These crimping pliers allow you to easily make your own wiring harnesses using crimp pins and cable housings. These are not a regular set of crimp pliers. These pliers are capable of crimping very small 1.25 - 2.5mm crimp pins. These work well with JST PH, SH, SHL, and ZH series pins as well as DF14 HRS and micro-latch from Molex. A similar set of crimpers from JST can be more than £250! We found these pliers to be very high quality at a great price.
