Description
“HSS” is the standard material used for all ITM drill bits. M2 has good red hardness and retains its cutting edge longer than other general-purpose high-speed steels because of its increased quantity of tungsten (dull red heat up to 1000° F without loss of hardness or rapid dulling of cutting edge).
