Milwaukee 48-89-2218 Titanium Jobber Drill Bit 2 Pack

Product Description

The MILWAUKEE 48-89-2218 is a titanium-coated jobber-length drill bit designed for extended service life and consistent accuracy in trade and jobsite drilling applications. The titanium coating reduces heat buildup to deliver up to 3 times longer life compared to standard high-speed steel bits. A thickened Thunderbolt web core adds structural strength and resists side-load breakage during aggressive drilling. The 135-degree split point tip starts on contact, eliminating walking and reducing the need for a center punch. Each package includes two bits.

This drill bit is suited for drilling through wood, metal, and PVC in both residential and light commercial applications. The parabolic flute geometry clears chips and debris rapidly to keep the bit cool during extended use. The reduced shank diameter allows use in 3/8-inch chucks, and the 3-flat shank design seats securely in the chuck to prevent slipping during operation. It is well-suited for portable drill use by electricians, plumbers, HVAC technicians, and general contractors working on curved or flat surfaces.

• 135-degree split point tip starts on contact and eliminates walking without a center punch
• Parabolic flute form evacuates chips quickly to maintain bit temperature and cutting performance
• 3-flat shank prevents slipping in drill chuck and accommodates 3/8-inch chucks via reduced shank diameter
• Effective on wood, metal, and PVC including curved surfaces

Compatibility

Designed for use with standard portable drills equipped with 3/8-inch or larger keyed or keyless chucks. Compatible with wood, metal, and PVC substrates in typical jobsite conditions.

Installation Notes

Installation of this bit is performed by electricians, plumbers, HVAC technicians, and general construction trades. Secure the bit fully in the chuck before operating the drill, ensuring all three flats engage the chuck jaws. Wear appropriate eye protection when drilling metal or PVC. Allow the bit to cool between extended drilling cycles to preserve coating integrity.
