iCrimp Micro Connector Pin Crimping Tool 0.03-0.5mm² Ratcheting Crimper for D-Sub, Open Barrel suits Molex, JST, JAE

I've wrestled with cheap crimpers for years, the kind that mash the connector rather than crimp it, leave you with intermittent connections and generally make a frustrating job even more so. The iCrimp Micro Connector Crimping Tool has completely changed how I approach connector work on the bench. The ratcheting mechanism is the single biggest upgrade over generic crimpers. It won't release until the crimp cycle is fully completed, which means every single crimp is consistent and properly formed. No more second guessing whether you applied enough pressure or accidentally released early. Once you've used a proper ratcheting crimper it's impossible to go back. The range of 0.03 to 0.5mm² covers an impressive spread of wire gauges and the die selection handles D-Sub, open barrel and a solid range of micro connectors that come up constantly in electronics work. I've used it on JST, Dupont and various automotive style open barrel terminals and every result has been clean, mechanically strong and electrically reliable. Build quality is immediately obvious when you pick it up. The tool feels substantial and precise, the jaws align perfectly, and the ratchet action is smooth and positive throughout the stroke. It feels like a professional grade tool rather than an entry level hobbyist purchase. For anyone working with small gauge wiring on PCB harnesses, RC electronics, automotive looms or any kind of custom connector work, the precision this tool brings is immediately noticeable. Stripped insulation is gripped cleanly, the conductor crimp folds correctly and the retention tab sets firmly every time. The ergonomics are comfortable even during extended sessions and the handles provide enough leverage that crimping smaller terminals doesn't require excessive effort. My only minor note is that the included die options, while comprehensive for most common work, may not cover every proprietary connector type. Worth checking your specific terminal dimensions against the spec before ordering. Bottom line: An outstanding crimping tool that produces professional results consistently. If you do any volume of connector work at all, the step up in quality and reliability over a basic crimper is immediately worth the investment. One of the best tool purchases I've made for the bench.

Bought to replace my non-rachet crimping tool which I lost. This has been a great upgrade, doing both crimps in one go for various JST connectors (I've done the PH, XT and 1.25 variants so far and all crimped well first time).

I have a love/hate relation ship with JST crimps. I like them, I really like them, they're an excellent connector to use on projects and they come in a variety of sizes and pitches, and they're used everywhere. What I didn't like was crimping them. The crimps themselves are small, and they are fiddly to crimp due to this. When I first started using them, I did a quick search and picked a crimper, probably the first hit that came up, and when it arrived, it didn't work, it was impossible to use. So I did a little more research and it seemed that the engineer PA-09 was the crimper to use, so I bought that and it had been my tool ever since. It worked ok, it required a a number of hand movements to use successfully, rotating the tool around and swapping hands, it was still fiddly, but it worked most of the time. I had a conversation recently about the crimps and somebody recommended this tool, I went and read the reviews and people raved about it, furthermore, there were a number of reviews that mentioned the previously tool I was using, and people described the exact failures I experienced fairly often, I'd put it down to me making a mistake and because the PA-09 was the "go to" it didn't cross my mind to go seek out further issues. So I ordered this, it was reasonably cheap and I had both a first hand recommendation and the reviews. It arrived earlier. Wow is all I can really say, the product, considering the price feels extremely premium, the handles have a lovely soft texture to them, there's so seam to cut into your hand, the actual dies are incredibly well made and finished, and the ratchet on it is very precise, has a satisfying action and has a positive feedback. The tool is weighty as well, indicating it's good quality. If you'd handed this to me I would be convinced it was a German manufacturer device, I use Wera, Knipex, Mitutoyo and Wiha tools and this is every single bit as well made as those tools, I'm astonished at the quality for the price. Most importantly, the crimps are crimped perfectly, much more precisely than the PA-09 ever gave me. If you're looking to crimp JST connectors, then don't bother with anything else, this is the tool to use. It's arrived just in time as I have a lot of JST cables (8 way - both ends JST) to make up for the project which you can see the PCB's for in my photo. I'm now looking at other IWISS tools which I can get to replace some other bits and pieces, based solely on this tool being so good.

Possibly early days to be boasting of 100% success rate with these, but I've crimped about 20 connections so far and they have all worked ! I spent a long time trying to get my previous crimper (SN-28B copy) to crimp anything and they almost always failed; this crimper on the other hand has produced perfect crimps every time ! Be aware that there were no instructions supplied with this item, which was a little annoying, but if you look at the "Crimping Guidance" image accompanying the listing you'll see how the barrels need to be inserted into the crimper and from there it's fairly straightforward. I would advise that you prepare the barrels beforehand by making sure that the "wings" are parallel to each other (as supplied, mine tended to be splayed a little too far) and then insertion into the crimper is a whole lot easier. I think the crucial thing about these crimpers is that they "fold" the wings onto the sheathing and therefore bring everything in together nicely. Excellent product!

This is an excellent quality crimper and there are zero concerns about reliability. It's a reasonable price too. I thought it was a wire stripper too which I needed as well but its not it's only a crimper. I'm going to donate this one to my local technical college as they always need tools and they're going to appreciate this a lot.

They work fine, not as good as the much more expensive single op tool; and no ratchet. Do the job and ok for a small number of crimps where you can take your time.

If you like crimp tools this is sex on a stick, or possibly on a handle! Very well made it dies those tiny crimps on JST and Wurth connectors. Much ! Cheaper than the regular tools. Works well.

Does as needed

Really good crimping tool.

Plus petite que je n'imaginais, mais conforme. A l'air solide et précise. A tester en condition réelle.

Köpte den till JST SH men behövde till PicoBlade, visade sig att tången skall passa båda +++

Bought a blue crimper sometime ago and was never successful in crimping connectors without wasting connectors. Especially micro JST connectors, was persistent in trying100connectors and all failed. I almost concluded it is the fault on my part until I bought Iwiss crimper. I was successful with the first try.

Excelente herramienta, crimosdo perfecto para conector de OBD2
