For Heavy Duty Applications, Cobalt Steel - M42Combines good wear resistance with high red hardness values and is specially useful for difficult machining operations. The increase in red hardness permits higher cutting speeds on general work materials and allows cutting of harder and tougher work materials which generate more heat at the tool's cutting edges.
