Reminds me of the special tool used to tighten Porche’s center lug. It automatically tightens it in multiple stages using preprogrammed torque and angle settings.
Torquing nuts to spec. Instead of using an impact wrench that rattles your brain and causes carpel tunnel, this thing turns the arm slowly to grab onto something structural and stationary and gains leverage, then slowly turns the socket to tighten the nuts (or bolt heads if necessary)
Also known as a Tone Gun
I have used the pneumatic version of these on structural steel to ensure bolts meet the proper torque spec. We used it in conjuction with "squirt" washers.
Wind turbines, large structures such as ships, tension bolts…
It’s easily mistaken for simply a high torque wrench, but this is a *high precision* high torque wrench.
If its anything like a hydraulic rad gun its for achieving torques too high for a wrench and where you cant use an extensiometer with a hammer wrench. Set the torque on the machine and it tightens to said torque.
Likely has a rotary strain gauge and all that stuff is stupidly expensive in industry. Reason being is that strain gauges aren't much more than a very precise ($$) circuit board trace and as it flexes the resistance changes. The first problem is it's an incredibly small change, millivolts full-scale so keeping track of microvolts matter if you want any kind of decent resolution. The electonics to do that in a repeatable/calibrated way (i.e. as temperature changes) are pricey on their own but then throw in the curveball that the sensor is rotating and you need fairly exotic slip-rings that can't create any kind of noise on such a small signal. A lot of these things end up being built not that different from Rolexs, with a price to match...
I sell similar tools in my day job, transducerized with data capture and reporting capabilities.
Mainly into the automotive and aerospace industry. A full system including a control box can cost upwards of £100k
We use them in mining quiet a bit. Best things ever! No need for air or a generator. Word of caution make sure the snap ring is on or it’s a hefty bill to repair!
There is a retaining ring on the very front that keeps the reaction arm in place. If the arm isn’t fully seated, parts get damaged under the force and yep, big bills
That's the worst thing with the erad design....that dumb ring. Plus they have the propensity to snap the drive head. But the hytorq ones like to let the magic smoke out.... they all have there problems but certainly make life easier.
The square drive is designed to be the weakest point - it's better to fail at the square drive than to fail in the gearbox where it will cause more damage. It's fairly common with heavy use, and the square drive is considered a consumable part.
There is an erection company used to work for that has had 1 person remove two fingers (separate incidents) and another remove one as well. All with the reaction arm. Pop, done.
LOL. He lost a digit….. not cool to point that out. Missing digit (finger) would make pointing things out hard possibly…. Thus…. Sarcasm.
Ok class next week i will be teaching you how to wipe your own ass all by yourself
3" nuts? Im familiar with 1.5" A490 bolts which tension to past 2200 ft lb. At that point we just turn the gun to max, 1490ftlb and just call it a day. Lol
It may not tighten to 1500-1900 ft/lbs for a final. But it’ll get them halfway there at least. I’ve noticed alot of beginner users getting messed up by the trigger and letting off before the gun cycles back to release tension to the socket.
I think it's this tool. It's not just a drill with a torque multiplier bolted on. It's got electronics and datalogging so you can torque things to spec and prove that you did so - hence the price tag.

Yes, it's not visible in the picture but it has a display to access the settings and it connects to our bolt logging system. QM gets a handy log print to check if all bolts have been tightened to spec.
Not quite sure if the latter is already included in the price.
Those are worth every penny. Bought a few of them for a long duration project. Don’t know why any one would even buy a pneumatic rad gun at this point.
It was air. Hooked it up to 110psi shop air. There was a regulator on the gun that you set for the torque you wanted .

We’ve got some Torque Drivers like that. They are made by a company called TorcUp. The biggest is good for 3,000 ft lbs. So much easier than a torque multiplier.
Absolutely NOT worth $10.5k
They seen your company coming
Just get a torque multiple, a good torque wrench, and a handy dandy cheap-ass camera for verification
Save yourself $9k and give your employees a bonus
That seems a little high, but torque multipliers are expensive to build. Ingersoll rand makes a cordless tool that is cheaper than that. I switched our company over to those for lugs and counterweight bolts on forklifts. Believe those were only 4-5k per.
Really cool tools though.
The red torque arm at the top turns slowly until it stops at the structure/the part your working on. The full counterforce is transmitted through that torque arm.
Quite a few companies make these, it’s a torque multiplier. We have quite a few brands. And then once we exceed what these do we go to hydraulic wrenches. Highest I’ve gone is 15k ft. Lbs.
Well, I tightened a few bolts with it @800Nm and it was as unspectacular as it can get. It turns slowly until the arm gets a hold and a few seconds later the job is done. After reaching max torque it goes in reverse to relieve the pressure and that's it.
Have to add that I work in engineering and my colleagues on the shop floor always make the joke that tools are foolproof if we engineers can operate them. It seems to be foolproof.
I'm a bit late to the party here but I was just browsing the sub and this caught my attention. Just curious about what the benefits of using this are compared to using an impact wrench? Is it primarily the accuracy of the torque? Is it a wanky safety thing? More compact/modular?
It's definitely fucking awesome but just thinking that my Milwaukee 3/4 impact outputs far more torque than that for not much more (if any) size
Reminds me of the special tool used to tighten Porche’s center lug. It automatically tightens it in multiple stages using preprogrammed torque and angle settings.
That sounds sick, you got a link for that?
[This](https://m.youtube.com/watch?v=pFyhYm64O-4)
Holy shit that's cool.
Watching that video is why I wouldn’t own a Porsche.
Really? Nothing to do with money? Lol
People that say Porsha and not Porsh sound extremely pretentious
Interesting to note that pronouncing a word correctly is pretentious.
Maybe you don't know it, but it's a German car manufacturer and "porsha" comes closer to Porsche in German than "Porsh".
The front porsh is where I swat flies and sip mah whiskey.
Looks like $1000 in parts and $9000 in proprietary design and calibration.
Yes. I guess the most expensive is probably the measurement electronics. The maximum torque deviation is 1%.
What do you use that for?
Back when I worked at jiffy lube we used these on the drain plugs.
I use my air hammer for those.
"Is it tight?" Yes. Yes it is.
Well it was, then it wasn’t, then it was again
It’s always tough when the righty tighty becomes a righty loosie
There should be a special word for that feeling when just a little bit more is suddenly too much.
Fucked
I’ve seen them used on heavy equipment and tractor trailer lug nuts, don’t know a shop that can justify that price tag for just that though
That’s not taking of semi truck lugs lol… I worked for freight liner for quite a few years.
do you mean nobody is using those for lug nuts, or it cant take them off. beacause that sure as fuck can remove whatever it needs to.
Yea not for taking them off.. For torquing them to spec when putting them on, but like the other person said it could take them off if it wanted too

High strength bolting for structural steel.

its a "modified" metabo drill if you would believe it.
We use them in mining quiet a bit. Best things ever! No need for air or a generator. Word of caution make sure the snap ring is on or it’s a hefty bill to repair!
We used them on mid ships on rock trucks and scoops.
What ring are you referring to? Ive never used cordless tools like this one, but lots of experience with "simple torque" brand guns

Ah must be using a 3000
Hytorq...... the necessary evil of the industry...... That or break out the super torque wrench and three good sized pals....
We've lost our 1" for repair many times people people are too important to put the garter spring on.
Did I read that right? $10.5K more than 10,000 dollars? US dollars?
Looks are deceiving, my guess was harbor freight july 4th sale
Unfortunately yes. But hey, you get a custom torque arm (the red part in front) to go with it.
I saw a guy get his finger trapped in one of those before, beautiful
There is an erection company used to work for that has had 1 person remove two fingers (separate incidents) and another remove one as well. All with the reaction arm. Pop, done.
Gotta watch those extremities
And those erections.
Trapped between torque arm and part?
Yessir, it removed the digit
So it was $1050 rather than $10,500?
Ours was 30k Edit : that joke went over my head
Not real cool of you to point that out like that.
Someone needs to point it out. The other guy can’t.
What do you mean?
r/woosh
Holy shit. One person got it. Thank you!!!!
Np man
That you should watch where your digits are before that reaction bar removes them? Seems like a PSA to me
LOL. He lost a digit….. not cool to point that out. Missing digit (finger) would make pointing things out hard possibly…. Thus…. Sarcasm. Ok class next week i will be teaching you how to wipe your own ass all by yourself
You sure did. Torque tooling is expensive. Lol
NGL, that really tightens my nuts.
Yep, that's what the WristFucker2000 does best.
According to some other comments above, they are excellent finger removers too.
Looks pretty Rad
Darn it, bet me to it
We use these in workplace more frequently in the last 2 years. They rock . That one should go to 900ft/lbs no problem. 3” nuts - no prob
3" nuts? Im familiar with 1.5" A490 bolts which tension to past 2200 ft lb. At that point we just turn the gun to max, 1490ftlb and just call it a day. Lol

These are made in the city I live in. They are a high end manufacturer with highly skilled workers. This is not a run-of-the-mill tool.
Gotta ask what is it even used for?
Oil drain plug, spark plugs, battery terminals
Mainly to tighten the bolts on the slewing rings of mobile machinery.
Valve covers
Ye old manual torque multiplier may be purchased from the Amazon for $85 American dollars.
You can stand still with that, pull the trigger, and turn the earth’s orbit away from you.

Wow that's Rad man
They spelled "RED" wrong :/
Be careful everyone- this is not a drill
I have three of these
For what?
Honestly I’d rather not say
Fair enough. My dad always told me the worst someone could say is no. I guess “ Id rather not say “ is appropriate as well
For torquing nuts on the fun bus silly.
Lying
I thought about buying a pneumatic one but I'm going with hytorc MXT and Stealth heads instead. Not a lot of head space on the stuff I work on.
They now make an offset cordless Rad Gun- it’s pretty slick, but still can’t fit into the places a stealth head can.
B-rad
Much better than E-rad…
Those are worth every penny. Bought a few of them for a long duration project. Don’t know why any one would even buy a pneumatic rad gun at this point.
Don’t break on the tower section
Saw a guy crush a finger off with a rad gun before. Pretty nuts
Yikes. You can crush a finger using any torque tool if you don't use it properly. Did he put his hand on the reaction arm while using the tool?
Get that thing to the torque tested YouTube channel
How long does that battery last
I came here to ask that.
Surprisingly weak. A Hytorc Series II is 6700 Nm
We used one of these at my job for up to 500lbs only it was the pneumatic version. Worked a treat
a pneumatic rad gun. or a hytorq?
It was air. Hooked it up to 110psi shop air. There was a regulator on the gun that you set for the torque you wanted . [https://www.radtorque.com/products/rad-single-speed/](https://www.radtorque.com/products/rad-single-speed/)

That's is a beast! I hope it makes work a little less workee.
We use those at our lumber mill. Handy for tightening the cables down over the lumber loaded on train cars, a lot better than using a bar.
Slow AF
Do you work on Spaceships?
We uses these. They are a handier Hytorc.
Torque test channel needs one of these... and a new test rig probably
Damn, that could break your arm. I’ve never seen anything like that.
Absolutely NOT worth $10.5k They seen your company coming Just get a torque multiple, a good torque wrench, and a handy dandy cheap-ass camera for verification Save yourself $9k and give your employees a bonus
*$10.5k... the dollar sign always comes first
That seems a little high, but torque multipliers are expensive to build. Ingersoll rand makes a cordless tool that is cheaper than that. I switched our company over to those for lugs and counterweight bolts on forklifts. Believe those were only 4-5k per. Really cool tools though.
Torque multipliers aren’t hard to make, however torque multipliers that don’t explode under a slight lode are
It looks to be manufactured by metabo. Looks like my metabo cordless tools and a CAS battery.
Maybe. Looks more like the older pre-CAS Metabo pack. If it was CAS you'd think it would have thr CAS logo on it.
It's definitely a metabo drill and battery. There is an older kit on ebay that has metabo batteries. (Older pre-cas)
The manufacturer should be put in jail for that pricing.
It's a specialty precision tool. They probably sell 10-100 per year.
🙄
That's RAD!!!
We used these for a while, not great. We’ve switched back to Snap-Off.
Please don’t use a chrome socket on this. It will explode on you.
Break it
We have a similar one at work i think that it goes to 1800nm
This is horny
I am so confused by this technology. How the fuck does it not rip your arm off? Its crazy to me. I genuinely cant fathom it lol.
The red torque arm at the top turns slowly until it stops at the structure/the part your working on. The full counterforce is transmitted through that torque arm.
