HSS Drill Bit Set M35 IMPERIAL 21Pieces: 1/16inch - 3/8inch The auger adds a longCobalt increases the strength of the steel and makes it more heat resistant; this is an important factor in drilling hard materials because the friction of metal against metal can produce high temperatures that damage the material or the drill bit. Will perform and outlast normal HSS bits particularly if drilling tough metals. Fully ground M35 HSS material increases drill life. 135 Split point cuts faster and reduces wandering.
