Milwaukee 48-89-2732 Black Oxide Jobber Drill Bit 6 in

Product Description

The MILWAUKEE 48-89-2732 is a black oxide jobber length drill bit built for demanding, repetitive drilling in metal, wood, and PVC. The Thunderbolt design features a thicker web core than a standard drill bit, providing greater resistance to side-load breakage during heavy use. A 135-degree split point tip starts on contact without walking, and a parabolic flute geometry evacuates chips quickly to keep the cut moving. At 6 inches in length, this bit suits portable drills across a wide range of trade and job-site applications. Licensed electricians, plumbers, HVAC techs, and general contractors rely on this bit for everyday hole-making tasks.

This drill bit is suited for use in residential and light commercial construction, mechanical trades, and maintenance work. The reduced shank diameter allows it to seat in standard 3/8-inch chucks, making it compatible with a broad range of portable drills. It performs on flat and curved surfaces and handles multi-material drilling without requiring bit changes. The black oxide coating reduces friction and resists corrosion during extended use in field conditions.

Installation Notes

Insert the bit fully into the drill chuck and tighten all three chuck jaws evenly before use. Power down the drill and disconnect it from any power source before changing bits. Use appropriate cutting fluid when drilling through hard metals to extend bit life. Follow applicable workplace safety standards and wear proper eye protection during all drilling operations.
