“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). M2 is generally favored for high production machine work.

135° drill bits have a fatter point which gives the drill bit more cutting surface area. When more surface area cuts the steel, drilling is faster.
