M42 HIGH-SPEED STEEL

 

 

APPLICATIONS

M42 is a high-speed steel suitable for cutting tools such as, twist drills, broaches, taps, milling, cutters, saws, reamers etc.  In terms of performance, 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. 

 

PROPERTIES

M42 is highly Cobalt alloyed.  The composition of M42 makes for a good combination of toughness and hardness.  By virtue of these well-balanced properties M42 has come into wide use for all cutting tools.
