A crimping tool is a specialized hand tool used to join two pieces of metal or other materials by deforming one or both of them to create a tight connection. This process, known as crimping, is commonly used in electrical work to attach connectors to wires, ensuring a secure and reliable electrical connection. Crimping tools come in various designs, tailored for specific applications, such as electrical connectors, cable terminals, or fiber optic cables. They typically feature a set of jaws that apply pressure to the materials being joined, allowing for efficient and effective assembly in various industries, including telecommunications and automotive.
