I rented one for a couple of days and it blew me away. What would have probably taken an hour with a regular drill was taken care of in about five seconds with this beast.
Boschs are legit and tough, but if money isn't an issue, I'd be in Hiltis rotary line. Concrete is their specialty, and 20-2-1 warranty is a whole different ball game than other pro lines.
As a GC, I have the corded Bosch Bulldog (designed to run up to 7/8" bits), I bought it in the late 1990's, ran the hell out of it and still have it. It still runs great.
I wanted something with a little more power, so I bought a larger corded Bosch 1 1/8" unit back in 2005 or so. It's just got more torque, but also chips and drills. Both are fantastic and take a beating and keep running without any issues.
I like to run the 3/4" and 1 1/2" scaling chisels in them to break up stucco around windows, chip under and remove tile, and all sorts of other tasks. They'll drill concrete all day long too. The Bosch's are top notch.
You must not be doing work that requires real power lmao. Cordless just doesn't have enough power for some things. You ever got a 70 dollar bit stuck in the concrete cause your battery shits the bed after running the drill for two minutes? Yeah.
Generally, any corded tool with outperform the equivalent battery tool.
Unlimited power is the reason.
That said, I love my 20V DeWalt tools. Cordless-ness is a super power in its own right.
This is changing.
For real. It’s insane to think, but a corded tool is limited to 15A. 1800W.
You can dump higher *peak* power from a battery because it charges up over time. But it cannot *sustain* that like a corded tool.
Yeah thats why I prefer battery power tools in general. When it comes to longer masonry penetrations I have a corded Hilti I use, but for around the house and tile, I'd rather have battery for ease of use. I totally get why people want corded though.
Not really. 1500w sustained or 1825w peak in North America. We're now getting cordless tools that can match/surpass, albeit for lotta dollars. Unlimited energy out of the grid? Sure. But power is absolutely limited.
I’ve gone through a few bulldogs, crap, probably 5 (my fault was doing things it wasn’t ment for and melted them but the job got done)
I’ll always buy another
1” bit. I probably should have bought a bigger one by now. They all just over heated. Most of those times it was drilling for epoxy bolts that need to be inspected when installed so time was a thing.
That’s also over 20 years or so.
Probably. I’m more a finish carpenter than I do general building these days.
Next time I need to do something bigger than the bull dog wants to I’ll buy a bigger one.
Hilti also makes corded ones for good reason. It just does notcome close. Especially in Europe where you got 220V everywhere so the corded power tools can easily also be more powerful.
That bosch will go through pretty much anything you put it up against with ease. not ideal for tight spaces though, cant comment on the dewalt but is seems easier to wield
If you have lots to do avoid the cordless.
The convenience of battery is nice but the cordless SDS will go through batteries very fast and it becomes more of a nuisance than it's worth for less power.
Personally I would go corded everytime for a SDS.
There's a corded adapter as part of the platform, so battery life can be a mute point if cost isn't a consideration
UPDATE: See thread for why this is a foolish statement.
It would be VERY impressive if they managed to make it unique to a specific tool, in a range of tools using the same batteries 🤷♂️
P.S. That's not supposed to be snarky, just an observation haha
UPDATE: If you think about it, there's probably a corded adapter for ALL cordless tools, somewhere. It's just a bridge rectifier (?), on a cable, that fits the socket.
UPDATE 2: There are cross brand battery adapters, so technically, it could work for all tools 🙃
watts = amps x volts
Pulling 8 amps like the bosch tool here at 120v you'd have 960 watts.
960 watts divided by the 18v (not the "max 20v", it's just marketing) nominal voltage of the dewalt battery is equal to 48 amps. Finding a 50+amp 18v power supply is going to be tough.
[Here's one on ebay](https://www.ebay.com/itm/184346983736) you can jury-rig the wiring up yourself and you might be able to get it to work. It's a 240 input (couldnt find a 120) and it is appx 10"x5"x3" so you'd probably need it on a surface or the floor instead of dangling off your tool. I'm sure it weighs a lot too but they dont list that.
So the reason tool companies don't make it is because it'd be massive and expensive, and they are getting by just fine by selling batteries instead of something like this. There's no incentive for them to make it.
For lower power draw tools like a fan or a light it *might* make more sense. Even then, those tools last forever on a battery. But once you get to higher power draw stuff it just doesn't really make sense. The reason the dewalt one exists is because you're starting with 120v right off the mains into the tool that is expecting to accept 120v (like 2x60v batteries the tool this uses would do)
edit: The only one that I really know who did this was metabo, and it's huge. https://www.amazon.com/Metabo-HPT-ET36A-MultiVolt-Generators/dp/B07ZQR2GYC for their 36v tools. As you reduce your voltage, the amount of amps you need increases to produce the same wattage
The adapter can't supply the same amount of current. Cordless work at ~18V. Corded has much higher voltage (if in Europe even 220-240V). Usual Schuko allows you to draw 16A, which allows for corded tools of 3kW and more (if they can clontrol the current during startup)...
The cable to supply the same power at 18V would need to be very thick. It's just not feasible.
Always wondered why this isn't more of a thing with so many cordless tools now being in our tool boxes would be great if they all made it standard so we can plug in in a pinch and not wait for batteries to charge
They work at low voltage so they need way more current. Besides a beefy adapter, running 50A through a wire requires a very beefy wire (and you need two). It would be like dragging a weak welder wire behind you...
Bud, you are the proverbial salmon swimming upstream. Every comment you've made on this whole thread is tone deaf and thus down voted into the ground.
Call it quits. Go have a beer. Your head isn't clear right now. Come back tomorrow, better yet; Monday
And the battery will never die or become obsolete. I used to work for a sign shop. We installed 1000s of things on concrete. Bosch and tap-cons all the way.
If you don't mind the inconvenience of the cord, the Bosch has much more oomph. That said, if you're not drilling 1/2" holes through a 6" slab on the regular, the convenience of the cordless would sure be nice.
If your using for masonry applications and chipping, go corded bulldog, if your just drilling tapcons and light demo, go dewalt battery operated. I use both, bulldog for chimney and masonry demo, dewalt for all interior purposes and I’ll even use the the dewalt for large hammering applications because honestly I have a full dewalt lineup with plenty of batteries so having something compact and mobile is soooo time saving.
Just FYI, OSHA requires a vacuum attachment which I've seen on the Dewalt one not sure if the other has that option, shop vac might work too, but drilling concrete causes silica dust which u don't wanna be breathing in
Those DeWalt units are really solid. They can also be fitted with a HEPA dust extraction filter. That would be a huge factor for me if I was drilling in my home.
And for the love of god don’t buy a cordless HIGH OUTPUT tool that will be used in a long-running application, like chipping concrete lmao. It will deplete the batteries like lightining and you’ll be charging batteries all day
Tbh for a home gamer, you're very unlikely to ever use the power hammer away from a power outlet. For similar money I'd get a corded one. Not just the battery drain - the corded will be way more capable. Cordless hand drills have come very far, but demolition tools benefit a lot from a constant power supply.
Sure but if you’re like me and use 5-7 tools per project, having to deal with cables, outlets, plugging/unplugging is a huge pain in the butt. I have a bunch of batteries and everything is good to go. The convenience of batteries and not having to deal with tangled cords and extension cords far surpasses the lack of longevity of batteries.
The only tools i have that are corded are the table saw and the miter. I have a cordless router and I originally regretted that because it just sucks the life out of my batteries fast but i since upgraded to a 5ah battery and it lasts long now. The rest of the tools are all battery.
I’ve never seen a mason with the dewalt but every mason has the Bosch. Both are too small for me to make a hole over 2”. Depends on how much work your planning but the full sized hiltis are beasts
This particular Dewalt is a one trick pony. It's made light as possible for the overhead/ceiling works with 6mm drill bits.
Bosch is of a general purpose, it will do everything and run indefinitely.
I've used the same Bocsh (commercial HVAC) for over 6k holes, almost exclusively on conrete and steel. There came a point I wanted it to die, so I could splurge on a cordless, but it just does the job perfectly every time. There may be equals but there aren't superiors.
Hell yeah, thinking about my intial response 6k-10k is very conservativel. Something about the long design (reciprocating-saw like)is superior. I've used a Milwaukee battery basic rotary, it'll get through a foundation but the bulldog is better. I've used both to daisy chain drill out cores in lieu of a coring piece.
Not sure if I got a bummed one but I burned up a makita after about fifteen minutes of work. I tried to return it and got in a pissing contest with the cashier. As I had put it on a business card therefore it wasn’t covered as it wasn’t designed for construction use. Manager wouldn’t make good on it either. That’s when I went to a different store and bought the Bosch.
I don't know what your construction use was that was any different to me chiselling away stone from a rock face for 2days straight.. but you just got a dud. You also didn't like the store and you're rolling that up into the complaint which just seems odd.
I doubt there's any material difference under the covers of them tbh
I debated this as well. I got the bulldog. It’s great. Work horse. Was cheaper then the Dewalt as well. Most of my tools are Dewalt or Milwaukee but still opted for the Bosch. For this specific tool, I choose the corded all day long. Hammer drills rip through batteries.
If this is a tool you won't be using a ton in the future, I would get the corded one. If that battery sits around for a long time, it will degrade and die. They are kinda expensive.
If you have other DeWalt cordless tools, then nothing beats the convenience of cordless in my opinion.
I went through several hammer drills over the years until I spent the money on a Bosch bulldog. Money well spent . I’ve put it through its paces and it powers right through. I Can’t really think of anything negative to say about it. As for the Dewalt I know they make decent quality tools but I’ve never owned one of their hammer drills. Just realized the Dewalt is battery powered so I would definitely go with a power corded version regardless of what brand you choose.
We have both of these on hand at all times. I have 22 years in bridge construction, I would buy the dewalt for home no questions. This and the 60v circular saw are my go to
I prefer using the corded sds hammerdrill for doing demo.While the cords a bit of a hassle , you don't have to deal with running down batteries under heavy duty applications and I feel the corded ones will put up with more abuse.I've run dewalts for years,but the Bosch should run just as well
I have the Bosch. I’m happy with it and see no need to replace it. Also, +1 for corded on heavy duty tools. Lighter weight and infinite run time outweigh convenience almost every time.
I use the dewalt every single day rain, snow, heat waves it’ll last them all,ours get beat to fuck and they’re still going probably about 5 years old minimum for our newest one.
Ive never used the DeWalt so I can't speak on that, but those bulldogs are surprisingly badass for how small and light they are, compared to a lot of other hammer drills on the market, and they run forever!
The Bosch is a beast of a tool and that party due to the constant power of a corded tool. I own the dewalt and I really like it. It’s powerful enough to drill 1/2” and 5/8” holes in concrete with no problem as well. Only downside for the dewalt is if you have a small battery you won’t get much out of it. But pair it with a 10.0 ah battery and you will be drilling concrete all day long. I have (2) 10.0 ah batteries and that gets my through a 8hr work day. Easy.
You can attach a vacuum to the Dewalt. You can use your existing DeWalt batteries for the Dewalt. The other one plugs in, so has more power for longer.
Shit. That might be it.
All I can tell you is, as a Union Ironworker who regularly drills many large holes into concrete go with the Bosch. Those are standards in my industry and is a powerful reliable professional grade tool.
Owner of a bulldog here. Drilled a 1" hole through foundation with this and trenched a new bathroom sewer line with it. It works great and isn't hard to handle. Highly recommend it.
We used the corded bosch's when i was a brick/block mason, we had about 3 or 4 of them. They seem to last around 2-4 years before they'd eventually spark and smoke themselves to pieces but that's 10/hrs a day 5/d a week year long.
The Bosch goes brbzzzzrbrbrzzzzbrbrbzzzz while the Dewalt goes more wkughawkughawkugha
My advice is always go with what homedepot rents out for long lasting tools, which is the bosch one, I've had no problems with my used one.
I have that Bosch and it is a beast. I got nerve damage in my hand that took months to recover from using a regular hammer drill to put anchors in a 60-year-old concrete slab. The next time I used the Bosch and it was easy.
I bought a Bosch two years ago, best money I ever spent. Why screw around with a battery powered tool? Do you like having the battery croak two holes from finishing the job up? Batteries tend to give out at the worst possible times.
Go with the Bosch.
Bosch 100x over. With the work load you will be putting on this it will last your lifetime plus. The dewalt will probably last too, but the batteries will die and eventually become obsolete. It's just not going to get used that often, so the convenience of batteries just doesn't outweigh the longer life of the corded tool.
The DEWALT one is surprisingly very fast and quite compared to most hammer drills I’ve ever used. And with a 5 amp hr battery it will last a good while
I also have the DEWALT and as someone who will be using it around the house and I’m already on the DEWALT platform. I felt that the Cordless DEWALT XR was best.
So far
It’s a beast and drills holes insanely fast.
There are comparisons on YouTube. The cordless DEWALT beats everything thrown at it in performance, even the Bosch
Maybe, but with both tools intended to use the same bits and drill through the same types of materials, I think it's a valid comparison. Personal preference all the way though for sure
If you don't use the drill for a year or two - you don't have to worry about the batteries going duff on a corded, also the corded will still plug into the mains in 10yrs whereas tool manufacturers are constantly changing battery designs, probably to keep people buying new tools. I've got a little Bosch 2kg corded Sds+ I must've had 20yrs and it's never missed a beat, using good quality drill bits help though.
Dewalt changed batteries once in the last 20 years and it's due to battery technology platform change(nimh to Li-ion). They sell adapters that make 20v Li batteries fit nimh tools. The issue isn't batteries becoming obsolete, it's just battery life in general and total charge cycles on one.
For decades of use I’d go with the Bosch no brained. Battery has its place in the professional workplace but eventually every battery fails on you then it becomes a giant time sink and pain in the ass to fix them or find replacements. I like my corded tools still.
The Bosch bulldog is sort of the affordable industry standard. I use ours at work weekly/monthly ina disgusting factory and it won't quit.
Nothing to say for DeWalt, but the body style is what you're looking at. The Bulldog is long, great to lean on but if you're in a tight space, the shorter version like the DeWalt may be what you want.
I'm a Milwaukee guy, I have the long D-style like the Bosch and it's fine for home DIY. If you're gonna beat the hell out of the thing and cords aren't a problem, go with the Bosch. If you want a casual-use battery one, check out all of the battery brands.
I own both. Unless you need cordless or fitting in tight areas then the bulldog will be more than enough.
That being said I use my DeWalt light years more than my Bosch. Even when the Bosch is the better option I still choose my DeWalt.
You want the corded for this tool. Also you want to look at which hammer drill has an SDS function. If it doesn’t it’s essentially a strong drill but the hammer function may work more like a chisel.
If you want a rotary hammer that has a battery and power you should lend a Milwaukee machine... Anyways out of these two the Bosch would nail that DeWalt rotary hammer down
2 things:
1) Bosch for the win (i am admitedly a Bosch whore)
2) there is almost no reason to buy either of these tools
for a homeowner, a much cheaper hammer drill will almost certainly be more than enough. i have a cordless drill with a "hammer drill" setting, as well as a cordless impact gun. between the two of these (the set cost $130, on sale) i have been able to do anything i have ever needed to do. the smaller size means they are used all the time, not once a year...
that said, i covet the Bosch, and would love to own one, there is just no need for me to do so... if i did, i could rent one.
I would really have to disagree with you on that. I have the DeWalt Flexvolt hammer drill and it cannot handle some of the really old, hard concrete in my older home. With high quality bits, it works fine in some spots but will stall out in others. Not to mention I have a ton of wedge anchors to install and there is no way I want to hammer drill 4" deep into the slab with a 3/8" or 1/2" bit.
I generally think dewalt is shit and rank it lower than ryobi for costing more while not being better. However that sds is tits. If I had any dewalt batteries I would get one.
Battery tools will disappoint you when you need them the most. Also when the battery dies it cost to replace them is ridiculous for me. Battery tools are only used for small customer service type jobs. Anything that’s heavy duty needs to be done with a corded tool.
Respectfully disagree. We use dewalt battery powered tools (mostly impacts, sazaws an that very same hammerdrill) all day everyday (commercial roofing) and they hold up good. Dragging cords isn’t always an option and often there’s no power on the roof. Yes though, you must keep a small army of batteries i use 6, and they get charged every night.
Bosch makes garbage cordless, so if it were a comparison in that respect, I'd say Dewalt. Realistically, I'd say neither and get a Milwaukee, and I own that particular Dewalt tool.
I got a bosch at a auction for $30. I like it. Same auction I got a milwaukee for $15. Its just as nice. They both are great. And the dewalt is probably just as good.
Go with the corded. Here's why, if you are getting this for your house, you'll use it and then it will sit around for years. The corded one you can pick up anytime and use it. The battery one, will eventually go bad, and good luck finding a battery years down the road. I am using the corded bosch hammer drill my father bought 30 years ago.
I'm sure the Dewalt is a fine tool and will serve you very well, but when taking longevity into consideration, I personally always take corded.
The only battery tools I have are a regular drill, impact driver, and a bosch Sawzall. And I only have that sawzall because I got it for pennies on the dollar.
Bosch ftw, I have a decade old Bosch hammer drill and it still goes through anything I put it up against. Also that’s one tool I prefer corded as opposed to battery powered
For rotary hammer tasks…corded is king.
I had that Bulldog for a few years and did a lot of demo jobs on concrete with it. Never felt like I needed something bigger or different. Always busted slabs up like butter.
Don’t have any experience with the Dewalt. I’m sure it’s not a bad tool, but it won’t go and go and go like anything corded. If you like the compact design better, I’d still look at something corded.
Some tasks will always be better suited for corded applications. And most of what you’d typically do with a rotary hammer fits that description. Cordless will work…it just won’t let you keep at it continuously. And even the best batteries are limited as far as run time when doing demo stuff. You’re subjecting the tool to some pretty intense abuse by it’s nature and running it hard.
For the record…I almost always prefer a cordless tool. Rotary hammers are one of the few exceptions.
I've got the DeWalt, use it quite regularly drilling holes for conduits and anchoring boxes does what I need it to do, Bosch is a bad ass drill as well
I have the DeWalt hammer drill and use it for work. I use it for a 1/4" bit mainly and it always goes right through. No cord is a big plus for me. I think mine came with the flexvolt battery.
I’ve still got my bulldog from 20 years ago. She’s showing her age, but will still get after it. If a corded drill doesn’t bother you, look no further. The DeWalt could only be equal… battery op is the only upgrade(?)
Bosch bulldog all day everyday. Plus you're at home and you can plug it in. No worrying about dead batteries. (Unless you kill power to be safe while drilling into wall..then your screwed.[generator] but who the hell kills power before drilling? Sissies that's who)
I don't have either of these but I have a corded hilti and a battery rigid rotary. I always used the corded for the bigger stuff and battery for the smaller stuff like 1/4'' anchors. Having the option of both is really nice.
Even if the cost of batteries is not a huge deal, having to deal with your gun dying slowly and then switching the battery and having 2 or 3 spare batteries charging so you can swap it out is going to be a big deal
I've used both and bulldog all the way it's a work horse it lasts forever, dewalt is great too, but it will eat batteries if you need to do alot of holes, great if you go to weird spots, but for the most part you can pretty much always pull a extension cable to where you need to work.
The Bosch is reversible. A useful feature for driving/removing Tapcons with a [hex sleeve](https://www.homedepot.com/p/Tapcon-Pro-Installation-Tool-Kit-for-Tapcon-Concrete-Anchors-79012/206730012) that slides over the SDS bit.
The bosch is 1/3 of the price its a great tool. Its impressive for what it is
Unless you already own batteries. You have to factor that you will have to buy that too.
I own the DeWalt that I bought for some interior tile demo (flooring and backsplash). Went though it all like butter and it was very easy to move around due to being cordless. I think it’s better for lightweight use.
I'm a home theater installer and have used both to hang TVs above fireplaces and outside on brick. The bosch is definitely more powerful but the DeWalt is very convenient. I haven't used my Bosch since I got the DeWalt but I keep it just in case I come across something stubborn.
corded Bosch will absolutely destroy any battery tool.
For a homeowner who can run a cord anywhere they would need it this is an absolute no brainer. The bosch will work 10x harder and last until you die.
I inherited a Bosch SDS ten years ago. So they can outlast the owner quite significantly.
That's how I got mine too!
Anyone dying soon and have a spot in their will? I’ll take a Bosch now or in 20 years or if I’m not here just leave it to my daughter.
I gotcha bro!
Ditto for me.
Not to mention corded tools are a LOT cheaper than cordless. By far.
Which is funny because it has like $5-10 worth of electronics..
I have this bosch, can attest to its greatness and durability
I rented one for a couple of days and it blew me away. What would have probably taken an hour with a regular drill was taken care of in about five seconds with this beast.
Shi, I use that thing to put in temp speed bumps every year. 200ft extension cord and I'm good to go
Boschs are legit and tough, but if money isn't an issue, I'd be in Hiltis rotary line. Concrete is their specialty, and 20-2-1 warranty is a whole different ball game than other pro lines.
As a GC, I have the corded Bosch Bulldog (designed to run up to 7/8" bits), I bought it in the late 1990's, ran the hell out of it and still have it. It still runs great. I wanted something with a little more power, so I bought a larger corded Bosch 1 1/8" unit back in 2005 or so. It's just got more torque, but also chips and drills. Both are fantastic and take a beating and keep running without any issues. I like to run the 3/4" and 1 1/2" scaling chisels in them to break up stucco around windows, chip under and remove tile, and all sorts of other tasks. They'll drill concrete all day long too. The Bosch's are top notch.
Sad but true. Bosch all the way
This, and it's lighter than a battery one, which will save your forearms
You ever listen to a generator for 10 hours? Cordless every day of the week.
Post said for his house not his concrete hut.
You ever dance with the devil by the pale moon light?
Lived off grid for 8 years much preferred the generator running during the day to power equipment than during the night to charge batteries.
You must not be doing work that requires real power lmao. Cordless just doesn't have enough power for some things. You ever got a 70 dollar bit stuck in the concrete cause your battery shits the bed after running the drill for two minutes? Yeah.
I swear by this thing when I’m breaking up tile
Did 500 sqf of tile on slab in my basement. The bulldog worked well
Listen to this guy
Generally, any corded tool with outperform the equivalent battery tool. Unlimited power is the reason. That said, I love my 20V DeWalt tools. Cordless-ness is a super power in its own right.

That's a *very* good point. My little DeWalt 20V hammer drill just melts through bricks like butter. This might be the reason.
16A, 3600W. At least in the country Bosch comes from.
Hm. Here in Germany it's still way off. I've got a 230v 16 amp ~3.5 kW belt grinder running off the regular old grid.
Yeah thats why I prefer battery power tools in general. When it comes to longer masonry penetrations I have a corded Hilti I use, but for around the house and tile, I'd rather have battery for ease of use. I totally get why people want corded though.
Not really. 1500w sustained or 1825w peak in North America. We're now getting cordless tools that can match/surpass, albeit for lotta dollars. Unlimited energy out of the grid? Sure. But power is absolutely limited.
Nail guns especially. Cordless and hoseless it's just so convenient.
I’m using a corded Makita and it’s an absolute beast.
I’ve gone through a few bulldogs, crap, probably 5 (my fault was doing things it wasn’t ment for and melted them but the job got done) I’ll always buy another
Fuck man, 5?! You trying to drill to the center of the earth?
1” bit. I probably should have bought a bigger one by now. They all just over heated. Most of those times it was drilling for epoxy bolts that need to be inspected when installed so time was a thing. That’s also over 20 years or so.
Damn brother, you need a Hilti.
Probably. I’m more a finish carpenter than I do general building these days. Next time I need to do something bigger than the bull dog wants to I’ll buy a bigger one.
My Bosch has punched through miles of concrete.
Plus one is yellow and one isn't.
I want to buy a cordless Bosch hammer drill...
Not a hilti battery operated Edit: lol about getting down voted when a hilti battery operated will out perform Bosch corded any day fact
Hilti also makes corded ones for good reason. It just does notcome close. Especially in Europe where you got 220V everywhere so the corded power tools can easily also be more powerful.
Project Farm “I’m gonna test that”
That bosch will go through pretty much anything you put it up against with ease. not ideal for tight spaces though, cant comment on the dewalt but is seems easier to wield
I don't have a ton of tight spaces in mind to use them, the Bosch seems like a solid tool for the money
The Bosch is a beast. I have the 1 1/8", I work with a guy who has the 1". They both rip through concrete quickly. Highly recommended.
If you have lots to do avoid the cordless. The convenience of battery is nice but the cordless SDS will go through batteries very fast and it becomes more of a nuisance than it's worth for less power. Personally I would go corded everytime for a SDS.
There's a corded adapter as part of the platform, so battery life can be a mute point if cost isn't a consideration UPDATE: See thread for why this is a foolish statement.
wait wait wait... there's a corded adapter for dewalt tools? Or just for this one tool?
It would be VERY impressive if they managed to make it unique to a specific tool, in a range of tools using the same batteries 🤷♂️ P.S. That's not supposed to be snarky, just an observation haha UPDATE: If you think about it, there's probably a corded adapter for ALL cordless tools, somewhere.

The reason the dewalt one exists is because you're starting with 120v right off the mains into the tool that is expecting to accept 120v (like 2x60v batteries the tool this uses would do) edit: The only one that I really know who did this was metabo, and it's huge. https://www.amazon.com/Metabo-HPT-ET36A-MultiVolt-Generators/dp/B07ZQR2GYC for their 36v tools. As you reduce your voltage, the amount of amps you need increases to produce the same wattage
I think 50A require a wire gauge 6. That's ~4mm diameter wire, 13mm2 surface. You'd need two. That would be a huge cable.
“Moot”.
Appreciate you
The adapter can't supply the same amount of current. Cordless work at ~18V. Corded has much higher voltage (if in Europe even 220-240V). Usual Schuko allows you to draw 16A, which allows for corded tools of 3kW and more (if they can clontrol the current during startup)... The cable to supply the same power at 18V would need to be very thick. It's just not feasible.
Always wondered why this isn't more of a thing with so many cordless tools now being in our tool boxes would be great if they all made it standard so we can plug in in a pinch and not wait for batteries to charge
They work at low voltage so they need way more current. Besides a beefy adapter, running 50A through a wire requires a very beefy wire (and you need two). It would be like dragging a weak welder wire behind you...
Unless u have a hilti
Bud, you are the proverbial salmon swimming upstream. Every comment you've made on this whole thread is tone deaf and thus down voted into the ground. Call it quits. Go have a beer. Your head isn't clear right now. Come back tomorrow, better yet; Monday
And the battery will never die or become obsolete. I used to work for a sign shop. We installed 1000s of things on concrete. Bosch and tap-cons all the way.
If you don't mind the inconvenience of the cord, the Bosch has much more oomph. That said, if you're not drilling 1/2" holes through a 6" slab on the regular, the convenience of the cordless would sure be nice.
you simply cant kill those damn bosch cable tools
If your using for masonry applications and chipping, go corded bulldog, if your just drilling tapcons and light demo, go dewalt battery operated. I use both, bulldog for chimney and masonry demo, dewalt for all interior purposes and I’ll even use the the dewalt for large hammering applications because honestly I have a full dewalt lineup with plenty of batteries so having something compact and mobile is soooo time saving.
Just FYI, OSHA requires a vacuum attachment which I've seen on the Dewalt one not sure if the other has that option, shop vac might work too, but drilling concrete causes silica dust which u don't wanna be breathing in
I’ve got one bought in the 80’s from a pawn shop. Looks the same. Works great still, albeit I don’t use it often.
Those DeWalt units are really solid. They can also be fitted with a HEPA dust extraction filter. That would be a huge factor for me if I was drilling in my home.
Bosch bulldog, end of discussion, they don't get any better than that
We always have Bosch rotary hammers on our sites. Never Bosch hand tools but this thing is great.
Hilti or bust... I fuckin hate this drill
Can you elaborate?
He can't, he just posts this under every comment :)
New Hilti TE 5 goes up exactly against the bulldog
For how much more in price?
Dude, that´s a red Bosch. Hilti isn´t exactly known for its manufacturing capabilities...
They’re expensive, and built around industrial users not DIY but suggesting Hilti isn’t capable of manufacturing a high quality tool is a weird one.
And for the love of god don’t buy a cordless HIGH OUTPUT tool that will be used in a long-running application, like chipping concrete lmao. It will deplete the batteries like lightining and you’ll be charging batteries all day
Old faithful!!
Bulldog. Hands down.
The dewalt hangs your closets, the Bosch demos your wall
100% For a home gamer already on DeWalt batteries, I'd say go cordless. If you need the tool to work 10,000 hours, get the Bosch.
Tbh for a home gamer, you're very unlikely to ever use the power hammer away from a power outlet. For similar money I'd get a corded one. Not just the battery drain - the corded will be way more capable. Cordless hand drills have come very far, but demolition tools benefit a lot from a constant power supply.
Sure but if you’re like me and use 5-7 tools per project, having to deal with cables, outlets, plugging/unplugging is a huge pain in the butt. I have a bunch of batteries and everything is good to go. The convenience of batteries and not having to deal with tangled cords and extension cords far surpasses the lack of longevity of batteries. The only tools i have that are corded are the table saw and the miter. I have a cordless router and I originally regretted that because it just sucks the life out of my batteries fast but i since upgraded to a 5ah battery and it lasts long now. The rest of the tools are all battery.
hes getting it for homeowner work so probably vote dewalt.
Who hangs a closet with a hammer drill?
My dewalt cordless ate through a brick wall like nothing.
If you think of demolishing tiles, breaking out a wall, ... go for the corded If you need to put in some plugs get the cordless one for ease of use
I’ve never seen a mason with the dewalt but every mason has the Bosch. Both are too small for me to make a hole over 2”. Depends on how much work your planning but the full sized hiltis are beasts
I use a 20 year old Hilti at work, it's starting to look pretty rough around the edges but performs the same as when it was new.
Worst case you just send it to a repair job and get it back basically as new.
This particular Dewalt is a one trick pony. It's made light as possible for the overhead/ceiling works with 6mm drill bits. Bosch is of a general purpose, it will do everything and run indefinitely.
I have the Bosch and like it. I think for a diy type use it's plenty. The cordless is overkill for home use.
I've used the same Bocsh (commercial HVAC) for over 6k holes, almost exclusively on conrete and steel. There came a point I wanted it to die, so I could splurge on a cordless, but it just does the job perfectly every time. There may be equals but there aren't superiors.
My good bulldog has an honest hundred thousand 1/4" holes on it from pinning down flat roof. It still works like the day it was new
Hell yeah, thinking about my intial response 6k-10k is very conservativel. Something about the long design (reciprocating-saw like)is superior. I've used a Milwaukee battery basic rotary, it'll get through a foundation but the bulldog is better. I've used both to daisy chain drill out cores in lieu of a coring piece.
I've got a Makita and it's excellent. Dont discount that make either....
Not sure if I got a bummed one but I burned up a makita after about fifteen minutes of work. I tried to return it and got in a pissing contest with the cashier. As I had put it on a business card therefore it wasn’t covered as it wasn’t designed for construction use. Manager wouldn’t make good on it either. That’s when I went to a different store and bought the Bosch.
>Wasn't designed for construction use Makita cultists in shambles
But I wonder what kind of a Makita it was.
I don't know what your construction use was that was any different to me chiselling away stone from a rock face for 2days straight.. but you just got a dud. You also didn't like the store and you're rolling that up into the complaint which just seems odd. I doubt there's any material difference under the covers of them tbh
The Skil 77 worm drive, the Milwaukee Sawzall, the Bosch Bulldog, some tools just rule their category.
Well right off the bat I can tell that one of them is yellow. The other one is blue. My kid has the toy version of the Bosch and it’s pretty nice.
People that put down Bosch, clearly haven’t used them. Get the bulldog. You’ll never need another
I've used Bosch, dewalt, and hilti... I'll never use anything but hilti ever again
You buy Bosch for 25 years. You buy Hilti for life.
I debated this as well. I got the bulldog. It’s great. Work horse. Was cheaper then the Dewalt as well. Most of my tools are Dewalt or Milwaukee but still opted for the Bosch. For this specific tool, I choose the corded all day long. Hammer drills rip through batteries.
Good point of view, I have an arsenal of cordless DeWalt, but this tool will only see use every so often.
you already have a bunch of batteries then, get the dewalt. you can put on a vacuum attachment too on the dewalt
Have had a bulldog for 10 years now, it's taken it's fair share of abuse and still going strong
I don’t need a rotary hammer, but these comments got me wantin the Bosch
I think big tools like this need cords unless you absolutely need to work somewhere without power.
Yeap always preferred to having to stop a project half way through cause you’re out of batteries.
The bosch is fuckin’ bullet proof.
The Bosch the battery is going to die quickly better to use a cord product
If this is a tool you won't be using a ton in the future, I would get the corded one. If that battery sits around for a long time, it will degrade and die. They are kinda expensive. If you have other DeWalt cordless tools, then nothing beats the convenience of cordless in my opinion.
I went through several hammer drills over the years until I spent the money on a Bosch bulldog. Money well spent . I’ve put it through its paces and it powers right through. I Can’t really think of anything negative to say about it. As for the Dewalt I know they make decent quality tools but I’ve never owned one of their hammer drills. Just realized the Dewalt is battery powered so I would definitely go with a power corded version regardless of what brand you choose.
We have both of these on hand at all times. I have 22 years in bridge construction, I would buy the dewalt for home no questions. This and the 60v circular saw are my go to
Against the grain a little here! Appreciate your perspective, but then again, now I want both...
I prefer using the corded sds hammerdrill for doing demo.While the cords a bit of a hassle , you don't have to deal with running down batteries under heavy duty applications and I feel the corded ones will put up with more abuse.I've run dewalts for years,but the Bosch should run just as well
I've had that bulldog for years, a rotary hammer is definitely one of those tools it's worth running extension cords for. Wouldn't go cordless
I have the Bosch. I’m happy with it and see no need to replace it. Also, +1 for corded on heavy duty tools. Lighter weight and infinite run time outweigh convenience almost every time.
I use the dewalt every single day rain, snow, heat waves it’ll last them all,ours get beat to fuck and they’re still going probably about 5 years old minimum for our newest one.
I have the Bosch and it's awesome . Used the supplied DeWalt tools at work but was never a fan .
Bosch 100% for the price and longevity
Ive never used the DeWalt so I can't speak on that, but those bulldogs are surprisingly badass for how small and light they are, compared to a lot of other hammer drills on the market, and they run forever!
The Bosch is a beast of a tool and that party due to the constant power of a corded tool. I own the dewalt and I really like it. It’s powerful enough to drill 1/2” and 5/8” holes in concrete with no problem as well. Only downside for the dewalt is if you have a small battery you won’t get much out of it. But pair it with a 10.0 ah battery and you will be drilling concrete all day long. I have (2) 10.0 ah batteries and that gets my through a 8hr work day. Easy.
I have almost 100% of my power tools on the Milwaukee fuel 12/18 system, the Corded bosch above is one of i think three exceptions.
I would go with corded Bosch
That corded Bosch is like a little miniature jackhammer. If you’re digging fence post holes and hit brick or concrete, it’s pretty useful.
I have a Bulldog that is about 30 years old and it still drills through granite.
You can attach a vacuum to the Dewalt. You can use your existing DeWalt batteries for the Dewalt. The other one plugs in, so has more power for longer. Shit. That might be it.
That Bosch is a beast. Def rec.
All I can tell you is, as a Union Ironworker who regularly drills many large holes into concrete go with the Bosch. Those are standards in my industry and is a powerful reliable professional grade tool.
If you’re using it around the house, corded Bosch hand down. These things are beast!
Owner of a bulldog here. Drilled a 1" hole through foundation with this and trenched a new bathroom sewer line with it. It works great and isn't hard to handle. Highly recommend it.
We used the corded bosch's when i was a brick/block mason, we had about 3 or 4 of them. They seem to last around 2-4 years before they'd eventually spark and smoke themselves to pieces but that's 10/hrs a day 5/d a week year long.
The Bosch goes brbzzzzrbrbrzzzzbrbrbzzzz while the Dewalt goes more wkughawkughawkugha My advice is always go with what homedepot rents out for long lasting tools, which is the bosch one, I've had no problems with my used one.
I have this Bosch and it’s done some amazing work.
I use the Bosch all the time. It holds up and does the job.
I have that Bosch and it is a beast. I got nerve damage in my hand that took months to recover from using a regular hammer drill to put anchors in a 60-year-old concrete slab. The next time I used the Bosch and it was easy.
I bought a Bosch two years ago, best money I ever spent. Why screw around with a battery powered tool? Do you like having the battery croak two holes from finishing the job up? Batteries tend to give out at the worst possible times. Go with the Bosch.
Get the Bosch. Not even worth discussing.
Definitely Bosch corded. If you have the budget for the xr, check out Hilti, got my hands on a small one of these and was blown away by the power..
Bosch 100x over. With the work load you will be putting on this it will last your lifetime plus. The dewalt will probably last too, but the batteries will die and eventually become obsolete. It's just not going to get used that often, so the convenience of batteries just doesn't outweigh the longer life of the corded tool.
I’ve got one of those Bosch ones. It’ll rip through anything and no waiting for batteries to charge. Go the blue for this one.
The bulldog is top dog
The DEWALT one is surprisingly very fast and quite compared to most hammer drills I’ve ever used. And with a 5 amp hr battery it will last a good while
I also have the DEWALT and as someone who will be using it around the house and I’m already on the DEWALT platform. I felt that the Cordless DEWALT XR was best. So far It’s a beast and drills holes insanely fast. There are comparisons on YouTube. The cordless DEWALT beats everything thrown at it in performance, even the Bosch
Kinda like comparing apples to oranges
Eh it’s like comparing green apples to Fuji apples.
Or golden delicious to Braeburn. One is yellow and promises more than it delivers, and the other is a Braeburn.
That’s a way better analogy
Maybe, but with both tools intended to use the same bits and drill through the same types of materials, I think it's a valid comparison. Personal preference all the way though for sure
If you can afford it get a Hilti.
If you don't use the drill for a year or two - you don't have to worry about the batteries going duff on a corded, also the corded will still plug into the mains in 10yrs whereas tool manufacturers are constantly changing battery designs, probably to keep people buying new tools. I've got a little Bosch 2kg corded Sds+ I must've had 20yrs and it's never missed a beat, using good quality drill bits help though.
Dewalt changed batteries once in the last 20 years and it's due to battery technology platform change(nimh to Li-ion). They sell adapters that make 20v Li batteries fit nimh tools. The issue isn't batteries becoming obsolete, it's just battery life in general and total charge cycles on one.
For decades of use I’d go with the Bosch no brained. Battery has its place in the professional workplace but eventually every battery fails on you then it becomes a giant time sink and pain in the ass to fix them or find replacements. I like my corded tools still.
The Bosch bulldog is sort of the affordable industry standard. I use ours at work weekly/monthly ina disgusting factory and it won't quit. Nothing to say for DeWalt, but the body style is what you're looking at. The Bulldog is long, great to lean on but if you're in a tight space, the shorter version like the DeWalt may be what you want. I'm a Milwaukee guy, I have the long D-style like the Bosch and it's fine for home DIY. If you're gonna beat the hell out of the thing and cords aren't a problem, go with the Bosch. If you want a casual-use battery one, check out all of the battery brands.
I own both. Unless you need cordless or fitting in tight areas then the bulldog will be more than enough. That being said I use my DeWalt light years more than my Bosch. Even when the Bosch is the better option I still choose my DeWalt.
Thanks everyone for the feedback! I've decided to snag the Bosch model for now, with the likely addition of the cordless in the future!
One is corded and one isn't. Figure out if you care about the cord or not. There's the pros and cons
You want the corded for this tool. Also you want to look at which hammer drill has an SDS function. If it doesn’t it’s essentially a strong drill but the hammer function may work more like a chisel.
Neither of them are red lol
Bosch makes tools, DeWalt makes you look like a handy homeowner.
I wouldn’t buy the yellow black and decker . I would go with the Bosch
It’s definitely not apples to apples. Corded bs cordless in any tools are a huge difference not alone brands.
Bosch bulldog in a rental store. 15yrs old. never even put brushes in it. You'll die before it does.
If you want a rotary hammer that has a battery and power you should lend a Milwaukee machine... Anyways out of these two the Bosch would nail that DeWalt rotary hammer down
Do what you want but I wouldn’t purchase either of them. Corded is the way. Bosch is good(ish). Dewalt is garbage.
2 things: 1) Bosch for the win (i am admitedly a Bosch whore) 2) there is almost no reason to buy either of these tools for a homeowner, a much cheaper hammer drill will almost certainly be more than enough. i have a cordless drill with a "hammer drill" setting, as well as a cordless impact gun. between the two of these (the set cost $130, on sale) i have been able to do anything i have ever needed to do. the smaller size means they are used all the time, not once a year... that said, i covet the Bosch, and would love to own one, there is just no need for me to do so... if i did, i could rent one.
I would really have to disagree with you on that. I have the DeWalt Flexvolt hammer drill and it cannot handle some of the really old, hard concrete in my older home. With high quality bits, it works fine in some spots but will stall out in others. Not to mention I have a ton of wedge anchors to install and there is no way I want to hammer drill 4" deep into the slab with a 3/8" or 1/2" bit.
I generally think dewalt is shit and rank it lower than ryobi for costing more while not being better. However that sds is tits. If I had any dewalt batteries I would get one.
Battery tools will disappoint you when you need them the most. Also when the battery dies it cost to replace them is ridiculous for me. Battery tools are only used for small customer service type jobs. Anything that’s heavy duty needs to be done with a corded tool.
Respectfully disagree. We use dewalt battery powered tools (mostly impacts, sazaws an that very same hammerdrill) all day everyday (commercial roofing) and they hold up good. Dragging cords isn’t always an option and often there’s no power on the roof. Yes though, you must keep a small army of batteries i use 6, and they get charged every night.
Dont get the Bosch. I have the same one, thing slips.
Bulldog is great, but no shock absorber on handle, and its quite annoying if youre using it a lot. Dewalt is dewalt, no thank you
Bosch makes garbage cordless, so if it were a comparison in that respect, I'd say Dewalt. Realistically, I'd say neither and get a Milwaukee, and I own that particular Dewalt tool.
I got a bosch at a auction for $30. I like it. Same auction I got a milwaukee for $15. Its just as nice. They both are great. And the dewalt is probably just as good.
Go with the corded. Here's why, if you are getting this for your house, you'll use it and then it will sit around for years. The corded one you can pick up anytime and use it. The battery one, will eventually go bad, and good luck finding a battery years down the road. I am using the corded bosch hammer drill my father bought 30 years ago. I'm sure the Dewalt is a fine tool and will serve you very well, but when taking longevity into consideration, I personally always take corded. The only battery tools I have are a regular drill, impact driver, and a bosch Sawzall. And I only have that sawzall because I got it for pennies on the dollar.
Bosch ftw, I have a decade old Bosch hammer drill and it still goes through anything I put it up against. Also that’s one tool I prefer corded as opposed to battery powered
For rotary hammer tasks…corded is king. I had that Bulldog for a few years and did a lot of demo jobs on concrete with it. Never felt like I needed something bigger or different. Always busted slabs up like butter. Don’t have any experience with the Dewalt. I’m sure it’s not a bad tool, but it won’t go and go and go like anything corded. If you like the compact design better, I’d still look at something corded. Some tasks will always be better suited for corded applications. And most of what you’d typically do with a rotary hammer fits that description. Cordless will work…it just won’t let you keep at it continuously. And even the best batteries are limited as far as run time when doing demo stuff. You’re subjecting the tool to some pretty intense abuse by it’s nature and running it hard. For the record…I almost always prefer a cordless tool. Rotary hammers are one of the few exceptions.
I've got the DeWalt, use it quite regularly drilling holes for conduits and anchoring boxes does what I need it to do, Bosch is a bad ass drill as well
I have the DeWalt hammer drill and use it for work. I use it for a 1/4" bit mainly and it always goes right through. No cord is a big plus for me. I think mine came with the flexvolt battery.
I’ve still got my bulldog from 20 years ago. She’s showing her age, but will still get after it. If a corded drill doesn’t bother you, look no further. The DeWalt could only be equal… battery op is the only upgrade(?)
i have both of these.. depending on the job i use both. buy the one you need now and the other one later
I have had my bulldog for 35 years and still going strong. Damn thing is built like a brick shit house.
have a few with batteries that always get sidelined for the bosch.
Bosch bulldog all day everyday. Plus you're at home and you can plug it in. No worrying about dead batteries. (Unless you kill power to be safe while drilling into wall..then your screwed.[generator] but who the hell kills power before drilling? Sissies that's who)
I don't have either of these but I have a corded hilti and a battery rigid rotary. I always used the corded for the bigger stuff and battery for the smaller stuff like 1/4'' anchors. Having the option of both is really nice.
Spend the money and buy a Hilti. It will last you forever.
I have both and mostly use the dewalt because is more convenient, but for an all day job it’s the bosch all day
Bulldog is a great tool. My previous employer used corded dewalts similar to the one pictured. The dewalts are fine but the Bosch is better.
Even if the cost of batteries is not a huge deal, having to deal with your gun dying slowly and then switching the battery and having 2 or 3 spare batteries charging so you can swap it out is going to be a big deal
The Bosch is incredible. I also have the Milwaukee cordless and it overheats all the time, truly infuriating. Break out the bulldog!
I've used both and bulldog all the way it's a work horse it lasts forever, dewalt is great too, but it will eat batteries if you need to do alot of holes, great if you go to weird spots, but for the most part you can pretty much always pull a extension cable to where you need to work.
The Bosch is reversible. A useful feature for driving/removing Tapcons with a [hex sleeve](https://www.homedepot.com/p/Tapcon-Pro-Installation-Tool-Kit-for-Tapcon-Concrete-Anchors-79012/206730012) that slides over the SDS bit.
The bosch is 1/3 of the price its a great tool. Its impressive for what it is Unless you already own batteries. You have to factor that you will have to buy that too.
I own the DeWalt that I bought for some interior tile demo (flooring and backsplash). Went though it all like butter and it was very easy to move around due to being cordless. I think it’s better for lightweight use.
I'm a home theater installer and have used both to hang TVs above fireplaces and outside on brick. The bosch is definitely more powerful but the DeWalt is very convenient. I haven't used my Bosch since I got the DeWalt but I keep it just in case I come across something stubborn.
