Crimping pliers are specialized hand tools 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 electrical connection. The tool features a pair of jaws that can be squeezed together to apply pressure on the metal, forming a crimp. These pliers come in various designs and sizes, tailored for different types of connections and materials. Some models are designed for specific tasks, such as crimping RJ45 connectors for networking cables, while others can handle a range of tasks in automotive or construction applications.
