Milwaukee 13/32 in. Thunderbolt Jobber Drill Bit

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-degree split point tip delivers a precision start and prevents walking for fast, accurate holes. These black oxide bits require less effort to drill through metal, wood, and PVC, making them ideal for use with portable drills and effective for drilling on curved surfaces.
