Wire cutters(pneumatic tools) are tools that use compressed air to more efficiently make holes in or cut metal or resin. Even items that cannot ordinarily be cut manually can be easily cut with little force. Different products cut a broad range of materials including copper wire, steel wire, and resin, and they handle a broad range of work including crimping, bending, and crushing. In addition to lightweight and easy-to-handle small handheld types and types that can be incorporated to automatic equipment, machinery, and robots, there are also a variety of other types including slide-type that slides to cut and those for heat cutting where the blade is heated to cleanly cut plastic, resin, and the like. Selection can be made to fit different applications. An air compressor is required to compress air when using.
