Milwaukee 48-89-2221 Titanium Jobber Drill Bit 2-pack

Product Description

The MILWAUKEE 48-89-2221 is a titanium-coated jobber-length drill bit sold in a 2-piece pack, designed for trade professionals who need extended bit life and consistent hole accuracy in demanding jobsite conditions. The bit features a thicker-than-standard web core that resists side-load breakage, and a titanium coating that reduces heat buildup to extend sharpness and deliver up to 3x longer service life compared to standard high-speed steel bits. The 135-degree split point tip starts on contact without walking, making it effective on curved or irregular surfaces. A parabolic flute design clears chips and debris rapidly to keep the bit cool during extended use.

This bit is suited for drilling through wood, metal, and PVC in residential and commercial construction, HVAC rough-in, plumbing, and electrical work. The reduced shank diameter allows use in 3/8-inch chucks, and the 3-flat shank geometry locks securely in the chuck to prevent slipping during high-torque drilling. Licensed tradespeople and experienced DIYers working with portable drills will find this bit effective across a range of common jobsite materials.
