The Irwin Metric HSS Cobalt Drill Bits are perfect for drilling stainless steel and other high alloys. Their 135° split point grinding ensures perfect centring and reduced drilling pressure.
An industrial-quality ground flute ensures high-accuracy drilling and fast removal of chips. The drill bit body is manufactured from high-quality HSS steel containing 5% Cobalt (Co).
The added 5% Cobalt improves the red hardness (heat resistance) of the drill bit and results in significantly extended life. It has an attractive golden-tempered surface finish.
