Since the cutters used in machining are basically used for cutting metal materials, the term "cutter" is generally understood as a metal cutting tool. Cutters can be divided into five categories according to the form of the workpiece processing surface: cutters for processing various external surfaces, including turning tools, planing tools, milling tools, external surface broaches and files; hole processing cutters, including drill bits, expanding reamers, boring tools, reamers and internal surface broaches; thread processing cutters, including taps, dies, automatic opening and closing thread cutting heads, thread turning tools and thread milling tools; gear processing cutters, including hobbing tools, gear shaping tools, gear shaving tools, bevel gears and broaches; and parting cutters, including inserted circular saw blades, band saws, bow saws, parting turning tools and saw blade milling tools.
