Bosch Impact Tough™ Black Oxide Drill Bits are engineered for use in the higher torque impact drill/drivers. They provide longer life than standard drill bits, thanks to their tip design and black oxide coating. The coating provides less friction and thus less generated heat. The bits have impact-rated shanks. With long flutes for excellent speed, these bits are built for general-purpose applications and work great in wood, plastic and light-gauge metal materials. They are great for general contractors and installers.
