Milwaukee 48-89-2211 Titanium Jobber Drill Bit Set

Product Description

The MILWAUKEE 48-89-2211 is a titanium-coated jobber-length drill bit sold as a two-piece set, designed for professionals who need consistent performance drilling through wood, metal, and PVC. The titanium coating reduces heat build-up to extend cutting life up to three times longer than standard uncoated bits. A thicker Thunderbolt web core adds structural strength and resists side-load breakage during aggressive drilling. The 135-degree split point tip starts on contact without walking, and the parabolic flute geometry evacuates chips quickly to keep the bit cool during extended use. HVAC techs, plumbers, electricians, and general contractors rely on this bit for fast, accurate holes in a range of field materials.

The 48-89-2211 is suited for residential and commercial jobsite applications where a reliable general-purpose drill bit is needed across multiple substrate types. The reduced shank diameter allows use in standard 3/8-inch chucks, making it compatible with the compact and mid-size portable drills common in trade work. The 3-flat Secure-Grip shank prevents slipping in the chuck under load. Both bits in the set are identical, providing a backup when one is in use or dulled.

Key Features

• Titanium coating reduces heat build-up and extends cutting life up to three times longer than standard bits
• Thicker Thunderbolt web core resists side-load breakage under heavy drilling pressure
• 135-degree split point tip starts on contact and prevents walking on curved or slick surfaces
• Parabolic flute design clears chips and debris rapidly to maintain bit temperature
• 3-flat Secure-Grip shank prevents chuck slippage during use
• Reduced shank diameter fits standard 3/8-inch drill chucks

Compatibility

Designed for use with standard portable drills equipped with 3/8-inch or larger keyed or keyless chucks. Effective for drilling wood, metal, and PVC across residential and commercial jobsite applications.

Installation Notes

Insert the bit fully into the chuck and tighten securely before drilling. Confirm the chuck is fully locked to prevent slipping under load, particularly when drilling metal. Allow the bit to cool between extended drilling cycles to preserve the titanium coating and cutting edge. Installation and drilling work should comply with applicable jobsite safety requirements for the trade performing the work.
