iCrimp IWS-30J Ratchet Crimping Tool Set with 5 Jaws

A crimp made with ordinary pliers looks fine and then pulls apart, or works for months until vibration loosens it. A crimp is only good if the terminal is squeezed with the right shape and force, which is what a ratcheting crimper does: it won’t open until the full stroke is done.

This set puts five different jaws on one ratcheting frame, so the same tool handles insulated ring and spade terminals, bare terminals and flat tabs. For car wiring, speaker cables and battery leads, that covers most jobs.

Pro tip Do a pull test on every crimp: hold the terminal and tug the wire firmly. If it moves at all, cut it off and crimp a new one. It’s much easier to fix on the bench than inside a dashboard.
