48-89-2737 Thunderbolt Black Oxide Drill Bit, 31/64 In.

The Milwaukee 48-89-2737 Thunderbolt Black Oxide Drill Bit is a jobber-length drill bit engineered for durability and precision in demanding applications. Designed for general-purpose drilling in metal, wood, and PVC, this bit combines a reinforced core with advanced flute geometry to deliver fast, accurate results with minimal effort. The black oxide coating provides corrosion resistance for extended life.

The Thunderbolt web features a thicker core than standard drill bits, providing ultimate strength and protection against side-load breakage during high-torque drilling. Whether you're working on curved surfaces or tough materials, this bit resists breaking and maintains performance under demanding conditions, and requires less effort to drill through its target materials.
