This crimping tool can be used to crimp both male and female versions of our Tamiya connector crimp pins, mini Tamiya connector crimp pins, JST RCY connector crimp pins, JR crimp pins, Futaba J crimp pins, and crimp pins for 0.1″ housings onto 16-28 AWG wires to make custom cables. The crimping die has a width of 7 mm, and the tool offers ratcheting action for increased consistency and ease of use.
Using the Crimping Tool
Prepare the wire by stripping about 1/8" (3 mm) of insulation from the end. Place the wire in the crimp pin, lining it up so that the stripped portion lies between the inner set of tabs on the crimp pin, while insulated wire lies between the outer set of tabs.
Tip: Instead of removing the crimp pin from the reel by breaking it off at the base (as intended), it can be helpful to leave a small tab on the back of the crimp pin to help you line it up and hold it in place while crimping, as shown in the pictures below. Then, you can remove the tab after it is crimped.
Place the wire and crimp pin on the appropriate tooth of the tool’s die, making sure that the insulated end is on the raised and wider half of the tooth. The tabs should point toward the cavity on the other side of the die so that the tool bends them inward around the wire when it closes.
Close the jaws of the tool slowly and completely until they release. The tabs on a properly crimped pin should form one barrel around the wire conductors and another barrel for strain relief around the wire insulation.
