## Description

Knoweasy JST Crimper and Molex Crimper Compatible with JST, Dupont, Molex terminals - Precision Wire Crimp Tool - desertcart.com

Review: Excellent tool for deutsch connections - I got these to do one project. Well they work so darn good I am recommending them to anyone who works with these connections. Excellent crimp quality, and accuracy small and compact and a great value for the money for sure. Will not disappoint.
Review: Works great, very reliable. - I bought these for a specific project on my 3D printer but now that I can reliably make connectors I use it way more than anticipated. I mostly make JST and Molex connectors and it works great. I had to mess a few up before I found a reliable technique but now I can strip wires and make connectors super fast. Does the job. Very convenient and useful!

### ⭐⭐⭐⭐⭐ SN 01BM Red Handle Works for Futaba/JR R/C Connector Pins
*by K***A on February 5, 2019*

SN 01BM red handle work well for Futaba/JR R/C connector pins, servo/extension leads, small Rx battery leads. Need to get the hang of using it. Need to slightly "pinch, flatten or narrow" the spread of the insulation crimp ears until they are parallel to each other so the pin fits into and sits level in the tool before crimping. Getting the pin sitting level in the tool's "saddle/rounded/forming jaw" first and making sure the "narrow/crimping jaw" is sitting square and flat onto the rounded "U" of the pin is the key. >>Following info is for the cheaper blue handle sets that are available on Amazon as a "Do Not Buy" heads up.<< I bought and returned the blue handle $15 set. The jaws are too wide/thick for the Futaba/JR pins and crush the squared off portion where the plastic tabs need to lock the pin into the plastic blocks. Also the jaws were either rough or incorrect profile because every completed pin was stuck in the jaws and had to be pried out with a micro jeweler's screwdriver. They were also kind of snug and did not re-open themselves up after completing the crimp. I had to use my fingers from the inside of the handles to pop the crimpers open to setup another pin. Get these Red Handle "Knoweasy Pin Crimper for XH2.0mm XH2.54mm XH3.96mm Dupont D-Sub Terminals JST Pin Crimper, AWG 28-20 (SN 01BM" and start crimping.
