Milwaukee 48-89-2737 Black Oxide Jobber Drill Bit 6 in

Product Description

The MILWAUKEE 48-89-2737 is a black oxide jobber-length drill bit built for demanding jobsite use across metal, wood, and PVC. It features a thickened Thunderbolt web core that resists side-load breakage, a parabolic flute geometry that evacuates chips quickly, and a 135-degree split point tip that starts on contact without walking. The 3-flat shank locks firmly in the drill chuck to reduce slipping during high-torque drilling. The black oxide coating adds lubricity and corrosion resistance to extend service life. Licensed tradespeople and experienced DIYers alike rely on this bit for fast, accurate through-holes in a variety of common materials.

This drill bit is suited for residential and light commercial applications where a reliable general-purpose bit is needed across multiple materials. Its reduced shank diameter allows use in 3/8-inch chucks, making it compatible with a wide range of portable drills. The 135-degree split point is especially practical when drilling on curved or irregular surfaces where bit walking is a concern. It is sold individually and fits standard jobber-length applications in HVAC, plumbing, electrical rough-in, and general construction trades.
