Advantages:
M-2 is the most widely used high speed steel for general purpose cutting applications. With a high working hardness, M-2 has an optimum combination of wear resistance and toughness, making it desirable for non-machining applications such as punches, die buttons, cold heading inserts and cold forming rolls.
