Bosch Daredevil® spade bits deliver drilling performance that is up to 10X faster than conventional spade bits. The bit has a fully threaded tip that pulls it through the wood, offering best-in-class speed through 2x4s. The contoured-paddle design on each Daredevil spade bit clears chips efficiently for faster and cleaner holes, making them ideal for running conduit or pipe. The hex shank with power groove reduces bit slippage in the drill and makes it suitable for use with a variety of drill types, including impact drills. Do not use in drill press.
