BÖHLER high speed steels are used for machine tools such as drills, taps, hobs and broaching tools and in some cold forming applications. The properties required here are wear resistance, hot hardness and toughness which prevent breakage of cutting edges. This guarantees high tool life and low maintenance, and ensures a reproducible production process. Our high performance powder metallurgical high speed steels are a specialty. They are the mainstay in this demanding market segment. The characteristic properties of all high speed steel grades include:
