Cordless crimpers compress lug and splice connectors onto cable, making solderless connections that are mechanically stable and electrically sound to prevent signal loss. Cordless crimpers apply steady force for a uniform crimp, and they operate faster and with less effort than manual crimpers. Jaws and dies provide the point of contact for crimpers to crimp or cut cable (depending on the jaw or die type). They connect to compatible cordless crimpers to replace worn jaws and dies, change jaws and dies to crimp different cable sizes and types, or switch to cutting jaws and dies.
