Milwaukee® S&D Black Oxide drill bits are designed for extreme durability and long life. A specially designed parabolic flute form clears chips fast, while the 3-Flat Secure-Grip™ shank holds the bit firmly in the drill chuck. The 135° split point tip delivers
a precision start and prevents walking for fast, accurate holes.
Effective for drilling on curved surfaces, Milwaukee® Black Oxide bits require less effort to drill through metal, wood and PVC, and are highly recommended for use with portable drills.
