Milwaukee 1/4" Thunderbolt Black Oxide Drill Bit 48-89-2722
MAXIMUM CORE STRENGTH FOR HIGH-TORQUE DRILLING APPLICATIONS
Standard drill bits often fail under the lateral pressure of professional jobsite use, but the ThunderboltĀ® series is engineered to solve that specific pain point. By utilizing a thicker core than traditional jobber bits, the ThunderboltĀ® web provides superior torsional strength, effectively protecting against side-load breakage when drilling through heavy-gauge steel or dense timbers. The parabolic flute geometry is a critical mechanical advantage, ejecting chips at a higher velocity to prevent heat buildup and maintain the integrity of the cutting edge. For those operating high-torque cordless drills, the 3-Flat Secure-Gripā¢ shank ensures the bit remains locked in the chuck, eliminating the slippage that ruins both the bit and the workpiece.
- / ThunderboltĀ® Web Design: Features a reinforced thicker core to provide ultimate durability and resistance against snapping during aggressive drilling.
- / 135Ā° Split Point Tip: Precision-ground tip starts on contact to prevent bit walking, ensuring accurate hole placement without the need for a center punch.
- / Parabolic Flute Geometry: Optimized shape clears chips and debris rapidly to keep the bit cool and extend overall service life.
- / 3-Flat Secure-Gripā¢ Shank: Three flat sides provide a rock-solid connection in the drill chuck, preventing bit spin-out under high-load conditions.
- / Black Oxide Coating: Provides essential lubricity to reduce friction and offers excellent corrosion resistance for long-term jobsite reliability.
