Best Price Bosch TI2139IM 3/16 In. Impact Tough Titanium Nitride Coated Drill Bit

Bosch Impact Tough Titanium Nitride Coated Drill Bits provide 2X life over standard impact drill bits. Designed for use in the higher torque impact drill/drivers, they have an upgraded tip design for no-skate starts and a titanium cooling shield thanks to the titanium nitrate coating. The coating provides less friction and thus less generated heat. The bits have impact-rated shanks. Electricians, plumbers and HVAC pros will appreciate the tough construction of the bit, rated for heavy-gauge carbon steels, as well as light gauge metal and hardwood applications.
