Crimping tools are specialized devices used to join two pieces of metal by deforming one or both of them to create a tight connection. They are commonly used in electrical work to attach connectors to wires, ensuring a secure and reliable connection. The tool typically features a pair of handles and a set of jaws that apply pressure to the connector and wire. These tools come in various types, including handheld crimpers for small jobs and hydraulic crimping tools for larger, more demanding applications. Proper use of crimping tools is essential for maintaining the integrity of electrical connections and preventing issues like short circuits or signal loss.
