Cobalt Steel Morse Taper-Shank Drill Bits
With better heat and wear resistance than high-speed steel, these cobalt steel bits can run up to 25% faster and have a longer tool life. Install the Morse taper shank directly into the tapered spindle on machines such as drill presses and lathes. A split point keeps the bit centered without a pilot hole.
Titanium-nitride (TiN) coated drill bits last longer and can drill at higher speeds than uncoated drill bits.
