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 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.
Steel bit with split point that eliminates the need for a center punch and keeps from skating on hard materials; three flats on the shank for better grip on chuck. Used in applications on farms and in machine shops.
M-7 high-speed steel for strength, heat resistance and wear resistance when drilling in wood, metal or plastic. Can be used with keyless chuck. Three-flatted shank design provides better chuck grip and reduces slippage. All Silver and Deming bits are 6 in long and feature a 1/2 in reduced shank that fits all 1/2 in drills.
135 deg split provides greater durability to reduce breaking.
