Milwaukee 3/8 in. Jobber Drill Bit

Milwaukee Thunderbolt black oxide jobber length drill bits are engineered for extreme durability and extended operational life. Built with a thicker core than standard drill bits, the heavy-duty web provides superior strength and helps protect against side-load breakage during rigorous drilling operations. A specially designed parabolic flute form rapidly clears chips and debris, while the 3-flat Secure-Grip shank prevents slipping within the drill chuck. The split point tip delivers precision starting on contact and eliminates bit walking, making it highly effective for drilling through curved surfaces, metal, wood, and PVC using portable drills.
