Milwaukee 48-89-2216 Titanium Jobber Drill Bit

Product Description

The MILWAUKEE 48-89-2216 is a titanium-coated jobber length drill bit built for high-frequency use in trade and jobsite environments. The bit measures 4 3/8 inches in overall length and features a thicker-than-standard web core that resists side-load breakage during aggressive drilling. A titanium coating reduces heat buildup to keep the cutting edge sharper longer, extending service life up to three times compared to standard uncoated bits. The 135-degree split point tip starts on contact without walking, and the parabolic flute geometry clears chips quickly to maintain feed rate. Licensed electricians, plumbers, HVAC techs, and general tradespeople are the primary users.

This drill bit is suited for drilling through wood, metal, and PVC in both residential and light commercial applications. The reduced shank diameter allows use in 3/8-inch chucks, making it compatible with a wide range of portable drills commonly found on service vehicles and job sites. The 3-flat Secure-Grip shank prevents rotation in the chuck under load. It performs reliably on flat and curved surfaces, which is useful when drilling into pipe, conduit bodies, or structural members at awkward angles.

Key Features

• Titanium coating reduces heat buildup and extends cutting life up to 3x compared to standard bits
• Thicker web core provides greater resistance to side-load breakage
• 135-degree split point tip starts on contact and prevents walking for accurate hole placement
• Parabolic flute form clears chips rapidly to maintain drilling speed
• 3-flat Secure-Grip shank locks firmly in drill chuck to prevent slipping under load
• Reduced shank diameter fits 3/8-inch chucks for compatibility with compact portable drills

Compatibility

Designed for use with portable drills equipped with 3/8-inch or larger chucks. Effective for drilling wood, metal, and PVC across general trade applications.

Installation Notes

Install the bit fully into the drill chuck and tighten all three chuck jaws evenly before use. Ensure the drill is set to the appropriate speed for the material being drilled — lower RPM for metal, higher for wood. Wear eye protection when drilling metal or PVC, as chip ejection is aggressive with the parabolic flute design. Inspect the cutting tip before each use and replace the bit if the titanium coating is worn through or the tip shows visible damage.
