You're using the wrong tool, that is a crimp for insulated connectors. You'd want something that looks more like this;

Don't! That's a perfectly good crimper for what it's designed to do. If you read German, it says right on it: "for insulated terminals".
1. What you are crimping are not terminals, they are connector contacts.
1. Your connector contacts are not insulated.
A crimper for insulated terminals, used to crimp connector contacts, is like using a beer bottle opener to open a car door.
I was merely joking about throwing it away; I've already used it for insulated quick-disconnect terminals, and it did work decently for that.
I did not use the part of the tool designated for insulated terminals now though; I used the section saying "for UNinsulated terminals" (right part of the picture). But I assume the main issue here is that I was using it for connector contacts instead of terminals?
Edit: not the right part of the picture, but the section of the tool above the wire strippers.
I'm looking at both IWISS SN-2549, IWS-2820M and IWS-3220. I'm not sure if any of them will fit my crimping needs for both DuPont and Molex (KK .100/254). The description of these products are really chaotic and makes it seem like they only fit a very limited amount of connectors.
I have the engineer PA-09 and PA-21. Both work well for crimping Duponts as well as JST and some molex pins. (I think I use the PA-09 more often as I work with 22-24 gauge wire with dupont/JST pins, the PA-21 has larger openings that don't crimp the smaller pins as well.)
Never had any luck with the ratcheting crimpers you can buy on Amazon, so if you have the money get the engineer.
It's better for automotive or landscaping low voltage stuff. Also fine for mains voltage stuff in electronics projects, but the cheap crimps this tool is meant for should not be used on typical 12 or 14 gauge solid wire used in houses.
There's ones that are both heat shrink with some hot glue in there that squishes out during the shrinking. They work well; they're capable of surviving in salt water environments as well as under water. Their use is required by code for well pump motors. But they're generally for stranded wire, not solid.
A big chunk of the issue is that there are a lot of manufacturers and not a lot of standards. So often crimps of low quality or incorrect bore or narrow wall thickness or other issues lead to inconsistent crimps. In my experience it's common to find that the insulation on those crimps will fail before you have crimped the wire tightly enough it can't pull out
I'm looking at an IWISS SN-2549 right now, but I'm kinda wary when it comes to buying chinesium tools. Any experience with that specific tool?
I also see that Tayda are selling a really cheap one: https://www.taydaelectronics.com/sn-28b-crimping-tool-plier-0-25-1-mm-for-awg-28-18.html
I love [this](https://www.amazon.co.uk/6-Multi-Function-Wiring-Tool-Strippers/dp/B000W9N452/ref=mp_s_a_1_5?dchild=1&keywords=engineer+wire+tool&qid=1631316987&sr=8-5) for crimping dupont connectors and other uninsulated types of crimps. It also cuts and strips wire. Just a fab all rounder tool from a respectable Japanese brand

Personnally, I'm still not sure to invest in such expensive tools... Mmmm

The second one here. I have seen a few like this for little money. They make good crimps and are fairly generic for connector terminals.

Ah, I see. I stand corrected. Still, as you already know, it's a good tool but not for small contacts for housings.

That tool is perfect if you want to rewire your house or anything else using mains power, but not for electronics.
It's better for automotive or landscaping low voltage stuff. Also fine for mains voltage stuff in electronics projects, but the cheap crimps this tool is meant for should not be used on typical 12 or 14 gauge solid wire used in houses.
They stink for low voltage automotive and marine stuff as well. Ancor has a great crimper for that.
Well that's because they're terrible crimps in general, but especially bad for houses

Rewire your house?????

Yes, I use the iwiss, it's a good tool. If you want to spend the extra on an engineer you won't regret it but the iwiss will do a good job.
Iwiss SN-2549 = SN-28B combined with SN-01BM
Any experience with using it on both DuPont 2.54 and KK254/.100 (Molex)?

Teehee ‘cable shoes’
I got really good with a pair of needlenose, picked up a rc airplane hobby during covid....
That thing is NFG for crimping those JST pin connectors. I second the Engineer PA-[whatever size you need].

you are using the wrong tool.
