CarTech M42 high speed steel, a molybdenum-type super high speed steel containing high carbon and cobalt contents, is capable of being heat treated to high hardness levels.

This combination of composition and properties allows successful machining of high hardness materials and difficult-to-machine superalloys. Due to the alloy's high hardness, excellent hot hardness and wear resistance are obtained without loss of edge toughness.

Applications:
CarTech M42 high speed steel has been used primarily to machine difficult-to-cut or high hardness alloys. Typical tools made from the alloy include:

Broaches
Chasers
Drills
End Mills
Counterbores
Form Cutters
Gear Cutters
Hobs
Taps
Milling Cutters
