M2 High Speed Steel (M2) is a tungsten-molybdenum high-speed steel with a well-balanced composition suitable for a wide variety of applications. It has replaced T1 high-speed steel in most applications due to its superior properties and relative economy.
A general-purpose high-speed steel of the molybdenum type, M2 steel has balanced toughness, wear-resistance, and red hardness characteristics. This grade is frequently used in cold work punches, dies, and high-speed, light-cutting applications. Due to its better qualities, such as its bending strength, toughness, and thermo-plasticity, all of which are 50% greater than T1, M2 High Speed steel is by far the most often used high-speed steel in place of T1 in most applications. Group M steels make up over 95% of the high-speed steels produced in the US.

M2 is a standard high-speed steel grade. Having balanced alloy composition forms the basis of its high toughness and good cutting edge retention, rendering it suitable for a large variety of applications.
This grade is mainly used for all metal-cutting tools for roughing or finishing such as twist drills, diverse milling cutters, thread dies, broaches, reamers, countersinks, thread chasers, circular saw segments, shaping tools and woodworking tools. Also highly suitable for cold-forming tools such as cold extrusion rams and dies, as well as cutting and precision cutting tools, plastic molds with elevated wear resistance and screws.
