Milwaukee 48-89-2710 Black Oxide Jobber Drill Bit 6 in

Product Description

The MILWAUKEE 48-89-2710 is a black oxide jobber length drill bit built for demanding jobsite use. The Thunderbolt-series web features a thicker core than a standard drill bit, providing greater resistance to side-load breakage during heavy drilling cycles. A parabolic flute geometry clears chips and debris rapidly, reducing heat buildup and extending bit life. The 135-degree split point tip starts on contact without a center punch, eliminating walking and delivering fast, accurate holes. Installed by electricians, plumbers, HVAC techs, and general tradespeople, this bit is suited for use with portable drills on curved or flat metal and wood surfaces.

The 48-89-2710 is designed for everyday trade use in residential and light commercial applications. The reduced shank diameter allows it to seat in standard 3/8 inch chucks, making it compatible with a wide range of portable drills commonly found on job sites. The 3-flat Secure-Grip shank design locks the bit firmly in the chuck and reduces the risk of slipping under torque. Ideal for drilling sheet metal, structural steel, wood framing, and similar materials encountered in HVAC, plumbing, and electrical rough-in work.

Installation Notes

This drill bit is used by licensed tradespeople across HVAC, plumbing, and electrical trades. Ensure the drill chuck is fully tightened around the 3-flat shank before operation. Wear appropriate eye protection when drilling metal or other hard materials. Replace the bit if the cutting edge shows visible wear or if drilling performance degrades, as a dull bit generates excess heat and increases the risk of breakage.
