Milwaukee 48-89-2715 Black Oxide Jobber Drill Bit 6 in

Product Description

The MILWAUKEE 48-89-2715 is a black oxide jobber length drill bit built for demanding jobsite conditions. It features a thicker web core than a standard drill bit, providing superior resistance to side-load breakage and extending overall service life. The 135-degree split point tip starts on contact, eliminating walking and delivering fast, accurate holes without a center punch. A parabolic flute geometry evacuates chips and debris efficiently, reducing heat buildup. The 3-flat secure-grip shank locks firmly in the drill chuck to prevent slipping under load. Weighing 0.03 pounds, this bit is sized for everyday use with portable drills.

This drill bit is suited for drilling into metal, wood, and other general-purpose materials across residential and commercial jobsite applications. The reduced shank diameter allows use in 3/8-inch chucks, making it compatible with a wide range of portable and stationary drills. Its parabolic flute design is especially effective on curved surfaces, where chip clearance and bit stability are critical. HVAC technicians, plumbers, electricians, and general tradespeople will find this bit useful for sheet metal penetrations, structural members, and fixture mounting tasks.
