Cable crimpers allow for the joining of cable, wire, and other ductile materials. Cable crimping dies are used to make reliable and controllable electrical connections when two wires need to be temporarily or permanently joined together. Crimping tool cutting dies can cut different sizes of cable, wire, metal rope, or solid steel bars with a crimper tool. Hand crimpers are manual devices used to crimp wires, cables, and other ductile materials. Voice and data crimping dies are used to crimp voice and data connectors. Manual hydraulic hose crimpers are handheld hose crimping tools that feature air-assisted pressure.
