Milwaukee 13/32″ THUNDERBOLTBlack Oxide Drill Bit

MAXIMIZED CORE STRENGTH FOR AGGRESSIVE DRILLING APPLICATIONS

The Milwaukee 48-89-2732 13/32″ Thunderbolt Black Oxide Drill Bit is engineered to solve the primary failure point of standard bits: core breakage. By utilizing the proprietary Thunderbolt web, which features a significantly thicker core than standard jobber bits, this tool provides the structural integrity required to withstand high side-load pressures often encountered in portable drilling. The parabolic flute geometry is specifically tuned for rapid chip evacuation, preventing heat-related dulling and ensuring the bit remains cool during extended runs in wood, PVC, or metal. This mechanical design ensures a higher return on investment for professionals who demand consistent performance in high-torque scenarios.

• / THICKER WEB DESIGN: The Thunderbolt core provides superior strength, drastically reducing the risk of bit breakage under heavy side-load.
• / 135° SPLIT POINT: Eliminates bit walking on contact, allowing for immediate penetration and precision hole placement without a center punch.
• / PARABOLIC FLUTE GEOMETRY: Optimized to eject chips quickly, maintaining lower operating temperatures and extending the life of the cutting edge.
• / 3-FLAT SECURE-GRIP™ SHANK: Prevents the bit from spinning in the chuck, ensuring maximum torque transfer even in high-demand applications.
