IWISS Mini Micro Open Barrel Crimping Tools Works on AWG2820 JAM, Molex, Tyco, JST Terminals and Connectors

Nice product

I bought these July 2019 as a quick, next day delivery, “get me by until I can grab a nice pair from the tool truck” tool. I thought for sure they’d get a few uses and fall apart, but here we are, May 2020, and they’re still crimping along, usually daily! I crimp every small connector I come across with these; JST-XH,ZH,SH and even PH! Losi, PicoBlade, DuPont (servo connectors), etc. I’ve yet to have an issue with them, they just work! The ONLY gripe I have is that tiny connectors are somewhat challenging to keep aligned for the first crimp BUT you’ll find this is the same with every crimp tool when working with tiny connectors. They’re tough, easy to grip and unbelievably accurate. PRO-TIP; If you’re having trouble crimping with any crimp tool; 1) Choose the largest groove on the crimp tool that the connector pin to be crimped will fit in to. 2) Align the connector pin to be crimped in the tool, make sure the open side of the section to be crimped faces the W shaped groove (remember; the crimp tool will fold the metal flaps over the wire and crimp them down into and around the wire. 3) Insert your wire into the pin, until the wire jacket is just outside of the area you’ll crimp the wire into. 4) Crimp It! *The wire, not the jacket* Then move your pin to the next smallest groove that it barely fits in to, and crimp it again! Continue until you get to the smallest spot it will fit in to without major resistance and then move in to step 5. 5) Crimp the wire jacket into the wire relief about half way, and then, like before where you start large and work your way down, crimp it the rest of the way, gradually working it down the smaller grooves until it looks snug. 6) Verify your work. Pull test! Be gentle if it’s a tiny wire. KEEP IN MIND; * If at any point this tool fails you, try again! * You will almost certainly crimp incorrectly several times, wasting pins, try again! * You will almost certainly pull the wire out of the pin a time or two, wasting more pins, and have to.. try again! * You will almost certainly crimp too hard a time or two and either break the pin or tear the wire, just try again! You’ll get it eventually... don’t give up and blame the tool, just try again! You can buy pins to replenish any failures pretty cheap here on Amazon. The last batch of pins I bought were 1000/$4. That’s expensive if you’re running through tens of thousands of them a day but we’re Makers and DIYers, not large assembly plants, so order more and TRY AGAIN! 😀

Cette pince est de bonne qualité et bien fabriquée. Elle nécessite un peu d'entraînement mais une fois maîtrisée, elle offre des sertissages très précis et fiables. La construction est robuste et semble parfaite pour une utilisation régulière (comme amateur en tout cas). Le prix est un peu élevé, mais elle est essentielle pour les amateurs de bricolage et les makers. Je recommande vivement cette pince !

Crimpatrice per microconnettori, molto precisa ed economica. Attenzione non va bene per i fast-on di dimensioni normali

no come back for electric so I believe it,s ok

Works very well
