The HSS Twist Drill Bit Cobalt provides long-lasting performance when drilling stainless steel. This extended lifetime results from a cobalt alloy content of 5% and fully ground HSS (high-speed steel), which provides excellent surface quality, wear resistance and heat protection. Equipped with two cutters and two flutes, chips are removed quickly to make the bit last even longer. This drill bit works with alloyed and non-alloyed steel, stainless steel, cast iron, cast steel and acid- and heat-resistant steels. This drill bit works with alloyed and non-alloyed steel, stainless steel, cast iron, cast steel and acid- and heat-resistant steels.
