Milwaukee Selfeed drill bits deliver speed and endurance for repetitive drilling of large holes. Designed for any trade that demands woodcutting for installing pipe and conduit, Selfeed bits feed into work without pressure and provide faster boring of clean, accurate holes. The bits have improved balance with reduced runout, while the hex shank provides a secure gripping surface for the drill chuck. Every Milwaukee Selfeed drill bit is coated with a rust inhibitor. Built to last and designed to perform, these Selfeed bits are re-sharpen able so you can keep them cutting like new. 2 feed screws are included.
