Features:

With high hardness and high temperature resistant nitride coating the surface, cutting blades are sharp. High speed, with super wear resistance and long service life. Forging repeatedly with air hammer, to improve its hardness and wear resistance. Under high speed it will show super fatigue fracture resistance of high speed steel. To prolong its service life, keep it warm in high temperature and high concentration of nitrogen for four hours to process deep nitrogen treatment on the surface, make it have strong cutting performance. Using machine tools to process coarse and fine grinding repeatedly on blade surface, as to achieve the high standard of surface finish. Mainly used for processing or cutting off on copper, iron, aluminum, alloy and other medium hard narrow and deep slot metal material. Can also be used for milling process on non-metallic materials such as plastic, wood.
