Fit most rotary tools with three jaw chuck for accurate centering.. Wide Applications: Used for metalwork, tool making, model engineering, wood grinding, welding, chamfering, casting, deburring, sculpting. Can process stainless steel, iron, cast steel, bearing steel, high carbon steel, alloy steel, copper, aluminum, jade, wood etc.. Carbide Tip Files: Made of tungsten carbide (tungsten steel), it features wear resistance, good toughness, heat resistance. Carbide material with good milling and cutting performance, ensures high work efficiency.. Double Cut Design: Designed with double cut. The groove lines are crossed. Double groove rotary files are more suitable for the object density is relatively low, such as wood, plastic, aluminum. Fit most rotary tools with three jaw chuck for accurate centering.. Tips: Requirement rotating speed is: 6000-50000rpm/min. Mainly used on electric or pneumatic tools (can also be installed on machine tools).
