Milwaukee 48-89-2227 Titanium Jobber Drill Bit 5 3/4 in

Product Description

The MILWAUKEE 48-89-2227 is a titanium-coated jobber length drill bit engineered for trades professionals who drill through wood, metal, and PVC on the job. The bit features a thicker-than-standard web core — the Thunderbolt construction — that resists side-load breakage during heavy-duty portable drill use. A titanium surface coating reduces heat buildup to extend edge life. The 135-degree split point tip starts cutting on contact without a center punch. Overall package dimensions are approximately 7.75 inches in length and 1.9 inches in width, with a packaged weight of 0.21 pounds.

This bit is suited for residential and light commercial jobsite work including electrical rough-in, plumbing penetrations, HVAC sheet metal, and general structural drilling. The parabolic flute geometry clears chips quickly to reduce heat and maintain cutting speed. The 3-flat shank seats securely in standard drill chucks and resists rotation under torque. The reduced shank diameter also allows use in 3/8-inch chucks, making this bit compatible with a wide range of portable drills commonly used by electricians, plumbers, and HVAC installers.

Installation Notes

Installation of this bit requires inserting the 3-flat shank fully into the drill chuck and tightening securely before operation. Inspect the cutting tip for wear or damage before each use. When drilling metal, use appropriate cutting fluid to further reduce heat buildup and extend bit life. Ensure workpieces are properly secured before drilling to prevent movement.
