M2 grade steel has a good red-hardness and retains its cutting edge sharpness longer than other general purpose high speed steel, but not as shock resistant or as flexible as other HSS grade with less tungsten. Sets furnished in metal or plastic case.
- 135° Self-centering Split Point prevents walking when starting a hole and is commonly on heavy duty tools.
