The longest tool life by high grade tungsten steel. Stable cutting screw threads improve rigidity on by optimize the edge and flute shapes. High performance without choosing work material, machine, cutting condition with high flexibility. Stable chips and cutting scene from Structural Steels to Stainless Steels, Aluminium AlloysHSS6542 surface TIN coating, used for drilling machines, tapping machines, CNC machining centers and other equipment. It can process steel, stainless steel, cast iron, ductile iron and other materials, which effectively reduces the problem of fragile breakage in the process of wire tapping.1. Using M35 Cobalt Containing Material. This material is currently the best grade of high-speed steel on the market. The cobalt content ensures the hardness and toughness of the high-speed steel. Suitable for drilling various metals, such as stainless steel, iron, copper, aluminum alloy, cast iron, and other metals, as well as various soft materials such as wood and plastic. 2. The thread part adopts the BLF structure, which effectively reduces the problem of easy breakage during the tapping process.
