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 three-flat Secure Grip™ shank holds the bit firmly in the drill chuck. The 135 deg 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.
