Product Overview
BIT DRL BLKOX 135DEG SP 5/16IN
Milwaukee Thunderbolt black oxide jobber length 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 protect against side-load breakage. 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 Thunderbolt black oxide bits require less effort to drill through metal, wood and PVC and are highly recommended for use with portable drills.
