Applications

M35  steel is usually used in conditions with the demand for high hardness. M35 steel is suitable for cutting tools such as cutting tools including broaches, milling cutters, reamers, end mills and saw blades. It is also a good quality wear resistant HSS grade for cold work area. Steel M35 is also suitable for cold work applications, where exacting demands are imposed on wear resistance. The steel possesses an admirable combination of wear resistance and toughness and in these respects superior to the high alloyed cold work steels.

Applications

M42 steel is a high-speed steel suitable for cutting tools such as, twist drills, broaches, taps, milling, cutters, saws, reamers etc. In terms of performance, HSS grade M42 is a steel to be used in conditions where the demand for hot hardness is of great importance i.e. where high performance is essential.

Typically employed to machine the super alloys and exotic, AISI HSS M42 tool steel is employed in drills, hobs, taps, end mills, milling cutters, form and gear cutters, broaches and chasers.
