Milwaukee 48-89-2733 Black Oxide Jobber Drill Bit 6 in

Product Description

The MILWAUKEE 48-89-2733 is a black oxide jobber length drill bit engineered for tradespeople who need consistent performance drilling through metal, wood, and PVC. The Thunderbolt construction features a thicker web core than a standard drill bit, providing increased resistance to side-load breakage during heavy use. A parabolic flute geometry evacuates chips quickly to maintain cutting speed and reduce heat buildup. The 135-degree split point tip starts on contact without walking, and the 3-flat shank seats firmly in drill chucks to prevent slipping. This bit measures 6 inches in overall length and weighs 0.15 pounds.

This drill bit is suited for general-purpose jobsite work in residential construction, mechanical contracting, and maintenance trades. It performs on flat and curved surfaces alike, making it practical for electrical rough-in, plumbing penetrations, and light fabrication tasks. The reduced shank diameter allows use in 3/8-inch chucks, broadening compatibility with common portable drill models on the job. Licensed electricians, plumbers, HVAC installers, and general contractors will find it a reliable everyday bit for mixed-material drilling applications.

Key Features

• Thicker web core resists side-load breakage and extends bit life compared to standard geometry
• 135-degree split point tip starts on contact and eliminates walking on curved or hard surfaces
• Parabolic flute design clears chips fast, reducing heat and maintaining cutting efficiency
• 3-flat shank prevents rotation and slipping in drill chucks during high-torque applications
• Reduced shank diameter compatible with 3/8-inch chucks for use with a wide range of portable drills
• Black oxide coating adds surface lubricity and corrosion resistance for extended tool life

Compatibility

Designed for use with standard keyed and keyless drill chucks, including 3/8-inch chuck capacity drills. Suitable for drilling metal, wood, and PVC in portable drill applications.

Installation Notes

Install the bit fully into the drill chuck and tighten all three flats evenly before use. Inspect the cutting tip and flute edges before each use and replace the bit if chipping or dulling is observed. When drilling metal, use appropriate cutting fluid to reduce heat and extend bit life. Follow applicable worksite safety codes and wear eye protection during all drilling operations.
