M42 High Speed Tool Steel Hardened & Ground Round

M42 is a molybdenum high speed tool steel with 8-10% cobalt added for increased hardness and hot hardness that is superior to other high speed grades and can obtain a hardness of up to 70 Rc. This results in a sharper cutting edge that lasts longer, even when being used to machine high-hardness and hard-to-machine alloys in heavy duty and high production applications.
