The Milwaukee Thunderbolt black oxide jobber length drill bit is a durable, versatile solution for drilling in wood, metal, and PVC. Designed for extreme durability and long life, this 3/8-inch bit delivers precision starts and prevents walking for fast, accurate holes in a wide range of materials and surfaces.
The thicker Thunderbolt web core provides ultimate strength and resists side-load breakage better than standard drill bits. The specially designed parabolic flute form clears chips quickly and efficiently, while the 135-degree split point tip ensures precise starts without walking. With its 3-flat Secure-Grip shank, the bit holds firmly in the drill chuck and works effectively with portable and cordless drills on curved surfaces. The black oxide finish reduces friction, allowing the bit to drill smoother and cooler while requiring less effort to penetrate tough substrates.
