Feature | |||
M2 is W-Mo high speed steel, with a good toughness, wear resistance, red hardness and other comprehensive performance, is widely used in cutting tools and with excellent machining performance. | |||
Application | |||
M2 can be used for a variety of purposes: twist drills, taps, milling cutters, reamers, saw blades, broaches, roll-to-inserts, gear cutters and other gear cutters. In addition to cutting tools with red hardness requirements, they can also be used as cold work tool steels, such as die cutting, forming and embossing. |
