Bosch Titanium Nitride Coated Metal Drill Bit Set (21-Piece)

Bosch Titanium Nitride Coated Metal Drill Bits have been designed to satisfy the needs of HVAC or facility maintenance technicians, contractors and other pros who need solid, reliable bits for general-application drilling in high-carbon steel and light-gauge metal, as well as wood and plastic. The split-point tip has been engineered for no-skate starts and clean, accurate holes. The bit provides 2X longer life than standard drill bits, thanks to the tip design and titanium nitride coating. The three-flat shank design on bits 3/16 In. and larger promotes better gripping and guards against slipping.
