Adafruit Universal Micro Crimping Pliers - 1.0 to 1.9mm Size Contacts [ADA350]
Make cables and wiring harnesses with ease using the best crimping pliers we've used. These precision machined crimpers will turn you into a pro, no more painful struggles with pliers and generic crimpers that smoosh your contacts so they wont fit properly.
This model will work best for smaller common connectors, from 1.0 to 1.9mm / AWG #32-20 - all those frighteningly small contacts used in fine pitch connectors.
There's a great website at ENGINEER Co. with lots of details. There is also a video tutorial showing how to use the tool so please check it out!
If you want to know whether it can do a particular pin number, they have a detailed compatibility chart as well
