Qibaok Crimping Tool Kit Ratcheting Crimper with 1550PCS 2.54mm Dupont Connectors and 760pcs 2.54mm JST-XH Connectors for AWG 26-20(0.1-0.5mm²)

This crimp has been a life saver. I got it just for a small project, but it worked out so great, I am starting to use it for all sorts of electrical projects. While there are probably much better crimping tools out there, the prices are outrageous! This is a solid crimp with a full set of supplies for 1/2 to 1/10 of the price of some of the others I have seen.HIGHLY RECOMMEND!

I bought this to switch out some connectors on some Stepper Motor cables, and to use for making the JST connectors for my Radio Controlled aircraft and cars. This works well and allows me to control the cable lengths and replace damaged connectors. There is a variety of connectors (some I will never use) but for the $$ spent I'm very satisfied. I strongly suggest you follow the instructions and you will find this tool and the connectors get the job done.

My only major dislike at this point was that the package was already open for the crimp tool. So clearly it had been returned by another purchaser most likely. However, it does work just fine, so maybe the previous user wasn't sure how to best use this crimp tool. That being said, I have used more friendly crimp tools, but once I got used to how this one works, I was able to build the harnesses with pretty good success.One other complaint would be that the black connector package has no connectors for the male pins. This isn't a major issue since I bought the kit for the female pins and holding connectors, but it makes me wonder why they included these pins.I really do like the white connectors that are board mountable with the mating harness connectors. These lock in quite well.

The Crimp Tool: I've used OEM crimp tools for many years (decades actually). I didn't know what to expect from a generic tool. Much to my surprise, this really works well with one slight issue. I found this works excellent on the DuPont crimps and on Molex 08-50-0114 crimp terminals. For the PST style, it works but takes more practice on figuring out where to align the pin for best crimping, since the head is a bit too wide for this terminal (as is almost every crimp tool I have seen). It might take a little adjusting of the tool setting to get it right but now I hit very close to 100% perfect crimps each time. The handles are very comfortable, and the operation is smooth. It is a robust and well-made tool.As for the Dupont and JST headers, they all worked great with no issues. Both may be generic rather than OEM (I honestly don't know) but they still work fine. I've used hundreds of them so far. The assortments provided were an excellent starting point until you see which sizes you need most. And it is nice to have an assortment for prototypes and the occasional repair.

Crimps hold very well - just takes a little practice. For the price this is a great product!

Please be gentle I'm a crimping newbie and probably using the wrong terminology ;-) I've found that you can successfully crimp JST-XH connectors but you MUST be careful and VERY precise, I'd say the tolerance is less than .1 mm.The biggest problem that I've run into is that if you're not careful you'll mangle the connector or flatten the "tang" that holds the connector in place in the JST header. The solution is to make sure that the connector is properly placed into the crimper jaws before crimping. Here are some tips that I hope will help and I've attached a couple of pics.- I think that whether you use the 1st or 2nd set of crimper "teeth" depends more on the gauge of the wire you're using than whether you're crimping JST or Dupont connectors. I've been using 24awg wire so I used the 1st set of larger teeth (closest to the mouth of the crimper).- I find that before inserting the connector into the crimper jaws pinching the connector wings that hold the wire insulation so that they're closer to parallel (instead of V shaped) makes things a little easier.- The biggest thing to watch out for is that the tang (see attached pics) protrudes from the opposite side of the jaws before crimping. If not the connector will be mangled or the tang flattened so it won't hold in the header.I hope this helps and good luck.

The ratcheting mechanism is a little janky, but this makes much better crimps than other budget options I have tried.

Crimps perfectly
