Files slide their cutting faces along workpiece surfaces to smooth and shape them. They remove finer amounts of material than chiseling and grinding tools. Files are used in manufacturing, maintenance, metalworking, woodworking, pipe fitting, auto bodywork, and more. American-pattern files debur, shape, and sharpen when material removal is the main objective. Swiss-pattern files make smooth cuts and remove small amounts of material for precision filing. Sharpening files hone, shape, and debur saw teeth and cutting edges. Electrical contact files remove oxidation and refine metal contacts on switches and relays. Thread-restoring files repair worn or slightly damaged external threads on bolts, screws, and pipe. File handles and holders add a comfortable grip for better control than holding the file directly. File cleaners clear debris from file faces and edges to extend file life and restore proper performance.
