Supreme Steels

M35

Product Description:

M35 is a high-speed tool steel that is an upgraded version of the M2 tool steel, with the addition of 5% cobalt. This gives M35 superior hardness, wear resistance, and strength, particularly at high temperatures. It is primarily used in cutting tools, drills, taps, and other tools that need to perform at high speeds and resist wear. M35 is often selected for applications that involve high-performance machining, such as high-speed cutting, drilling, and milling, where tools are exposed to high thermal and mechanical stresses. The addition of cobalt significantly enhances the heat resistance and cutting ability of the steel.
