Milwaukee 48-89-2224 Titanium Jobber Drill Bit 5 3/8 in

Product Description

The MILWAUKEE 48-89-2224 is a titanium-coated jobber length drill bit built for demanding jobsite conditions. The titanium coating reduces heat build-up to extend sharpness and deliver up to three times longer service life compared to standard uncoated bits. A thicker-than-standard web core provides added strength and resistance to side-load breakage. The 135-degree split point tip starts on contact without walking, and the parabolic flute geometry evacuates chips quickly to maintain cut speed. The 3-flat shank seats firmly in drill chucks to prevent slipping under load. Licensed HVAC, plumbing, electrical, and mechanical trades reach for this bit when drilling through metal, wood, and PVC on portable drills.

The 48-89-2224 is suited for residential and light commercial trade work where a reliable, general-purpose drill 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 drill drivers already on the job truck. The parabolic flute clears chips efficiently on curved or irregular surfaces, reducing the need for repeated withdrawal during deep holes. Electricians, plumbers, and HVAC techs will find this bit useful for conduit knockout prep, pipe penetration drilling, and sheet metal work.
