M2 high-speed steel is a tungsten-molybdenum tool steel. M2 is characterised by well-balanced toughness, wear resistance and red hardness properties.
AISI M2 high-speed steel has largely replaced T1 in most applications due to its superior properties and advantageous pricing. M2 is medium-alloyed and is a good all-round performer with good machinability, in this respect it is superior to the high alloyed cold work steels.
