Milwaukee 48-89-2738 Black Oxide Jobber Drill Bit 6 in

Product Description

The MILWAUKEE 48-89-2738 is a black oxide jobber length drill bit built for heavy-duty drilling in metal, wood, and PVC. The Thunderbolt web design uses a thicker core than a standard drill bit to resist side-load breakage and extend service life. A 135-degree split point tip starts on contact without walking, delivering fast and accurate hole placement. The parabolic flute geometry evacuates chips quickly to keep the bit cutting efficiently. This bit measures approximately 6 inches in length and weighs 0.22 pounds. It is suited for licensed tradespeople and skilled installers who require reliable performance from portable drill equipment on the jobsite.

This drill bit is designed for general trade use across electrical, plumbing, HVAC, and construction applications where drilling through metal, wood, and PVC is routine. The reduced shank diameter allows use in 3/8-inch chucks, making it compatible with a wide range of portable drills commonly found on residential and light commercial job sites. The 3-flat Secure-Grip shank seats firmly in the chuck to minimize slippage during high-torque drilling operations.
