Tool Steel – M2

Tool Steel – M2 (1.3343)

M2 steel is the "standard" and most widely used industrial high-speed steel, commonly used as cutting tool material. It is often used in power-saw blades and drill bits. After heat treatment, its hardness is the same as T1, but its toughness and thermo-plasticity are higher than T1 by 50%.

It is usually used to manufacture a variety of tools, such as drill bits, taps and reamers.
