Terminal tools are made from heat-treated No. 45 cold-rolled steel for long life and accuracy. Up-front crimping dies for 26-10 insulated terminals are color-coded for size. Easy to read engraved markings allow for easy placement of the different sized terminals into the tool. The crimping tool is ergonomically designed with a cushioned-grip and insulated handles. The Cambridge Crimping Tool is easy to use and tightly secures terminals to wires. The terminal crimping tool is heavy duty, but lightweight weighing only 7oz.
