HSS M2 as a tungsten molybdenum, widely used in the production of machine tool bits, cold forming tools and cutting tools. M2 high speed steel offers high toughness combined with good cutting powers and will withstand increases in temperature without losing its temper.DLDT is the excellent supplier of AISI M2 tool steel.
Applications
Typical applications for M2 high speed steel are twist drills, reamers, broaching tools, taps, milling tools, metal saws. M2 is suitable for cold forming tools such as extrusion rams and dies, also cutting tools, plastic mould with elevated wear resistance and screws.
