Milwaukee 48-89-2716 Black Oxide Jobber Drill Bit 6 in

Product Description

The MILWAUKEE 48-89-2716 is a black oxide jobber length drill bit engineered for high-cycle use in professional trades. The Thunderbolt design features a thicker web core that resists side-load breakage and extends service life compared to standard jobber bits. A parabolic flute geometry evacuates chips rapidly, reducing heat buildup during extended drilling. The 135-degree split point tip engages material on contact without walking, delivering accurate hole placement. A 3-flat shank design locks securely in the drill chuck to prevent slipping under load. This bit is well suited for electricians, plumbers, HVAC techs, and general contractors working with portable drills on the job site.

The 48-89-2716 is built for drilling into steel, wood, plastics, and other common construction materials encountered in residential and commercial trade work. The reduced shank diameter allows use in standard 3/8 inch chucks, making it compatible with a wide range of portable drill drivers commonly carried on the job. Its split point geometry performs well on curved and irregular surfaces where bit walking is a common problem, and the black oxide coating reduces friction and corrosion during storage and use.

Key Features

• Thicker web core provides greater resistance to side-load breakage and extends bit life
• 135-degree split point tip starts on contact and prevents walking for accurate hole placement
• Parabolic flute form clears chips and debris quickly to reduce heat buildup
• 3-flat secure-grip shank prevents slipping in drill chuck under load
• Reduced shank diameter fits standard 3/8 inch chucks
• Black oxide coating resists corrosion and reduces friction during drilling

Compatibility

Designed for use with standard portable drill drivers equipped with 3/8 inch or larger keyed or keyless chucks. The reduced shank diameter allows fitment in 3/8 inch chuck capacity drills commonly used in HVAC, plumbing, and electrical trades.

Installation Notes

This drill bit is installed and operated by any trade professional using a portable drill driver. Ensure the drill is powered off and the chuck is fully tightened on the 3-flat shank before use. Inspect the bit for cracks or deformation before each use and replace if tip geometry is compromised. Follow applicable OSHA hand and power tool safety guidelines when operating on the job site.
