Milwaukee 48-89-2229 Titanium Jobber Drill Bit 6.8 in

Product Description

The MILWAUKEE 48-89-2229 is a titanium-coated jobber-length drill bit built for demanding jobsite use across wood, metal, and PVC applications. The titanium coating reduces heat buildup and extends edge retention for up to three times longer service life compared to standard high-speed steel bits. A thickened Thunderbolt web core adds torsional strength and resistance to side-load breakage. The 135-degree split point tip starts on contact without center-punching and prevents walking on curved or irregular surfaces. Designed for licensed tradespeople and skilled installers who need consistent hole quality through a full shift.

This bit is suited for residential and light commercial installation work involving metal framing, conduit, plumbing rough-in penetrations, HVAC sheet metal, and general-purpose wood boring. The parabolic flute geometry evacuates chips quickly to reduce clogging during deep-hole drilling. The reduced shank diameter allows use in standard 3/8-inch drill chucks, making it compatible with compact drills commonly used in tight mechanical spaces. The 3-flat Secure-Grip shank seats firmly in the chuck and resists slipping under torque.

Key Features

• Titanium coating reduces heat buildup and extends bit life up to three times longer than uncoated HSS bits
• Thickened Thunderbolt web core resists side-load breakage during aggressive drilling
• 135-degree split point tip starts on contact and prevents bit walking on curved surfaces
• Parabolic flute design clears chips rapidly for cleaner holes and reduced heat
• 3-flat Secure-Grip shank locks into drill chuck and prevents rotation slippage
• Reduced shank diameter fits standard 3/8-inch chucks for use with compact portable drills

Compatibility

Designed for use with portable drills equipped with 3/8-inch or larger keyed or keyless chucks. Suitable for drilling wood, metal, and PVC in trade applications.

Installation Notes

Installation of this bit should be performed by qualified tradespeople familiar with rotary drilling tools. Ensure the drill is unpowered and the chuck is fully tightened around the 3-flat shank before operation. Select appropriate drill speed for the material being drilled — lower speeds for harder metals, higher speeds for wood and PVC. Inspect the bit for wear or chipping before each use and replace if the cutting edge is degraded.
