Supreme Steels

M2

Product Description:

M2 is a high-speed tool steel that is widely used in the manufacturing of cutting tools, such as drills, taps, and milling cutters. Known for its excellent wear resistance, high hardness, and ability to retain its strength at elevated temperatures, M2 is one of the most popular tool steels in the high-speed tool steel family. It is an alloy of tungsten, molybdenum, chromium, and vanadium, which gives it its outstanding wear resistance and toughness. M2 is commonly used in applications requiring tools that must maintain sharpness and durability at high speeds and temperatures.
