Milwaukee 48-89-2712 Black Oxide Jobber Drill Bit 6 in

Product Description

The MILWAUKEE 48-89-2712 is a black oxide jobber-length drill bit built for repeated use in demanding job-site conditions. The Thunderbolt design features a thicker-than-standard web core that resists side-load breakage and extends service life. A 135-degree split point tip starts on contact without walking, while a parabolic flute geometry clears chips and debris rapidly to reduce heat buildup. The black oxide coating adds lubricity and corrosion resistance. This bit is suited for electricians, plumbers, HVAC technicians, and general trade contractors who need reliable, accurate drilling through multiple material types with a standard portable drill.

The 48-89-2712 is designed for drilling through metal, wood, and PVC in residential and light commercial construction and service work. The reduced shank diameter allows use in 3/8-inch chucks, making it compatible with a wide range of portable drills commonly found on trade job sites. The 3-flat shank geometry reduces slipping in the chuck during high-torque drilling applications. At 6 inches in length, this jobber bit provides additional reach for installations where standard-length bits fall short.
