Milwaukee 48-89-2722 Thunderbolt Black Oxide Drill Bit

Product Description

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.

Product Highlights

This bit is great for drilling metal, plastic, and wood materials. Its design allows efficient performance with less effort when using portable drills.
