Bosch DSB5012 - 12-Piece 1/4 in.

Bosch Daredevil spade bits deliver the fastest drilling performance possible through wood, up to 10X faster than conventional spade bits. The bit as a full-cone threaded tip that pulls it through the wood, offering best-in-class speed through 2x4s. Ideal for clean-boring a lot of holes through wood fast to run conduit or pipe, these bits deliver a drilling speed and a force performance that sets them apart; these are not bits for counter sinking or Dowling. The spur-and-reamer feature on each Daredevil spade bit clears chips better, for a cleaner hole. 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.
