Milwaukee 48-89-2722 Thunderbolt Black Oxide Drill Bit Free Returns

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, which provides strength and protects against side-load breakage. The parabolic flute clears chips quickly, keeping the bit cool. A 135-degree split point tip starts on contact and prevents walking for fast, accurate holes, making it effective for drilling on curved surfaces.

• Designed for durability: thicker web offers greater strength.
• 135-degree split point for accurate drilling and prevents walking.
• 3-flat Secure-Grip shank reduces slipping in the drill chuck.
