Bosch TI9IM Drill Bit Set, Steel, Titanium Nitrate, 9-Piece, For High Torque Impact Drill or Drivers

Bosch Impact Tough cents titanium drill bits provide 2X life over standard impact drill bits. Designed for use in the higher torque impact drill or 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.
