VASCO M-30 is a high-speed tool steel containing nominally 8.70% molybdenum and 4.75% cobalt. It provides long life in machining difficult-to-cut metals, such as heat-resisting alloys and super-alloys. It is recommended for cutting tools requiring a good combination of suitable toughness with optimum cutting qualities. Typical applications of VASCO M-30 comprise milling cutters, broaches, drills, hobs, turning tools and dies. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on forming, heat treating, machining, and joining. Filing Code: TS-418.
