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

I wasn’t sure what to expect, but it’s better than I hoped. Worth every penny.

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!

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.

Perfect crimping of JST connectors as you can see in the photo. Certainly very helpful that is crimps both parts of the connector at once with different sizes so that there is proper contact between the wire and the sheath. Very good value, and made creating new stepper wires for my 3D printer an easy task.

This crimping tool needs a bit of practice but does a great job on the micro crimp pins and sockets.

First time I used this the ratchet mechanism stopped ratcheting! (Either the spring broke/detached or it was never there in the first place).
