What is a crimping tool used for in electrical work?

A crimping tool is specifically designed to permanently attach electrical fittings, such as connectors or terminals, to wires by deforming or "crimping" the metal of the fitting around the wire. This mechanical connection ensures that the contact between the wire and the fitting is secure and can handle the necessary electrical load without the risk of disconnection.

Crimping is a preferred method in many electrical applications because it provides a reliable and strong bond without the need for heat, as is the case with soldering. This can also save time and effort on installations where speed is crucial. Proper crimping is essential to ensure good conductivity and prevent issues such as oxidation, which can occur with soldered joints over time.

The other options describe different tools or processes related to electrical work. For instance, stripping insulation is typically done with a wire stripper, while cutting wires is performed with wire cutters. Soldering involves melting material to create a joint, which is distinctly different from the mechanical action performed by a crimping tool.
