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 more→work without pressure. 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 resharpenable so you can keep them cutting like new.

Featuring diamond-welded tips for long life and extreme durability, DEWALT Tile Drill Bits power through dense tile, solid-body porcelain, and more. Reverse-spiral threads enable continuous water cool more→ing for quick, clean drilling. Core ejection slots remove plugs for repeated cuts.

Milwaukee aircraft length black oxide drill bits are ideal for extra reach and deep drilling applications in metal, wood and PVC. The 135° split point tip delivers a precision start and prevents walk more→ing for fast, accurate holes. The 3-flat Secure-Grip shank holds the bit firmly in the drill chuck to prevent slipping.
