The HSS twist drill bit with cobalt provides long-lasting performance when drilling in stainless steel. The extended lifespan results from the 5% cobalt alloy content and HSS (high-speed steel), which offer excellent surface quality, wear resistance, and heat protection. 

With two cutters and two flutes, chips are easily removed to increase the drill bit's lifespan. This drill bit works with alloyed and non-alloyed steel, stainless steel, cast iron, and acid- and heat-resistant steel. 

This drill bit works with alloyed and non-alloyed steel, stainless steel, cast iron, and acid- and heat-resistant steel. It features a cylindrical shank system (the shank is the same size as the drill bit) and is intended for use in drill stands and drill drivers.
