Drill Bits for Precise Holes
Specially-designed flutes keep these bits centered as they drill, resulting in straighter, rounder holes with tighter tolerances. They are titanium nitride (TiN) coated for wear and temperature resistance. Also known as double-margin drill bits.

Extended-Length Cobalt Steel Drill Bits
Access hard-to-reach spots and drill deep holes. 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. The split point keeps the bit centered without a pilot hole.
