Milwaukee Thunderbolt Titanium Coated 9/32" Drill Bit 48-89-2215
REINFORCED WEB DESIGN FOR STRESS-FREE METAL DRILLING
The Milwaukee 9/32" Thunderbolt Titanium Drill Bit is engineered to solve the primary failure point of standard jobber bits: core breakage. By utilizing the proprietary Thunderbolt web, this bit features a significantly thicker core that provides the structural integrity needed to withstand side-load pressure and high-torque applications. The titanium coating acts as a critical thermal shield, dissipating heat during repetitive drilling in abrasive materials like stainless steel or thick PVC to maintain a razor-sharp edge up to 3X longer than oxide alternatives. For precision work, the 135-degree split point eliminates bit walking on contact, allowing you to start holes on curved surfaces or polished metals without a center punch. The 3-flat Secure-Grip shank ensures that all the torque from your drill is transferred directly to the workpiece, preventing the bit from spinning in the chuck under heavy resistance.
- / Thunderbolt® Web: Designed with a thicker core to provide ultimate strength and protect against side-load breakage in demanding materials.
- / Titanium Coating: Reduces friction and heat build-up, extending the life of the bit by up to 3X while maintaining superior sharpness.
- / 135° Split Point Tip: Delivers a precision start and prevents walking on contact for fast, accurate holes in wood, metal, and PVC.
- / 3-Flat Secure-Grip™ Shank: Provides a rock-solid connection in the drill chuck to prevent slipping and maximize power delivery.
- / Parabolic Flute Form: Clears chips and debris rapidly to keep the bit cool and maintain high drilling efficiency.
