48-89-2736 Thunderbolt Black Oxide Drill Bit, 15/32 In.

The Milwaukee 48-89-2736 Thunderbolt black oxide drill bit is a jobber length bit engineered for reliable performance in wood, metal, and PVC. This bit is designed for extreme durability and long life in portable drill applications. The black oxide coating provides corrosion resistance for extended tool life.

The Thunderbolt design solves common frustrations with standard bits: walking across curved surfaces, premature breakage under side-load stress, and slow chip removal that binds the drill. The precision split-point tip delivers accurate starts and prevents walking on curved surfaces for faster, cleaner holes.
