High speed tool steel
A tungsten-based high speed tool for a variety of common cutting tools. It does not contain molybdenum or cobalt. However, it is a relatively soft type in high-speed steel, but unlike SK material (tool steel), it is used at high speed in terms of wear resistance, impact resistance, hardness, and the like. In some cases it can be used.
