Product Details

Milwaukee Thunderbolt black oxide jobber length drill bits are designed for durability and long life. The thunderbolt web features a thicker core than a standard drill bit, offering superior strength and protection against side-load breakage. A specially designed parabolic flute clears chips quickly while the 3-flat Secure-Grip shank firmly holds the bit in the drill chuck. The 135-degree split point tip provides precision starts and minimizes walking, ensuring fast, accurate hole drilling. These bits excel on curved surfaces and require less effort to drill through metal, wood, and PVC. They are ideal for use with portable drills.
