Milwaukee 7/32" Thunderbolt Black Oxide Jobber Length Drill Bit (12 PK) 48-89-2830
ENGINEERED FOR EXTREME DURABILITY AND SUPERIOR CHIP EVACUATION
The Milwaukee Thunderbolt Black Oxide drill bits are engineered to solve the most common failure point in metal drilling: side-load breakage. By utilizing the Thunderbolt web—a significantly thicker core than standard jobber bits—these bits provide the structural integrity required for high-torque applications and portable drilling where tool orientation isn't always perfectly perpendicular. The parabolic flute geometry is a critical mechanical advantage, aggressively ejecting chips and debris to minimize heat buildup and extend the cutting edge's service life. Designed for professional-grade performance in steel, wood, and plastic, these bits ensure every hole starts with precision and finishes with efficiency.
- / Thunderbolt® Web: Features a thicker core that provides ultimate strength and protects against breakage during side-loading.
- / 135° Split Point: Precision tip starts on contact to prevent walking, ensuring fast and accurate hole placement without a center punch.
- / Parabolic Flute Form: Optimized geometry clears chips and debris rapidly to keep the bit cool and maintain cutting speed.
- / 3-Flat Secure-Grip™ Shank: Prevents the bit from slipping in the drill chuck, maximizing power transfer and preventing shank damage.
- / Black Oxide Coating: Provides essential lubricity and superior corrosion resistance for long-term jobsite reliability.
