Our THUNDERBOLT Black Oxide Drill Bit Set offers convenient, heavy-duty performance on the jobsite. Milwaukee drill bits are designed for extreme durability and long life. The THUNDERBOLT web features a thicker core than a standard drill bit to provide ultimate strength and protection against side-load breakage. Our 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 Degree split point tip delivers a precision start and prevents walking for fast, accurate holes. Black oxide drill bits are effective for drilling on curved surfaces. The Milwaukee THUNDERBOLT Black Oxide Bits require less effort to drill through metal, wood and PVC and are highly recommended for use with portable drills.
