Hex Shank Drill Bits | McMaster-Carr
Titanium Nitride (TiN) Coated Insert these bits directly into power screwdrivers, impact drivers, and other tools that accept 1/4' hex shanks. 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 black-oxide drill bits.
