Milwaukee 48-89-4814 Shockwave Titanium Drill Bit

Product Description

The MILWAUKEE 48-89-4814 is a titanium-coated jobber length drill bit engineered for use with both impact drivers and standard drills. Built on the SHOCKWAVE platform, it features a variable RED HELIX design with an aggressive 35-degree helix angle that transitions to 15 degrees, promoting rapid chip evacuation and reducing heat buildup at the cutting edge. The 135-degree split point tip starts on contact without walking, delivering fast and accurate hole placement. The titanium coating extends service life significantly compared to standard black oxide bits, making this a practical choice for high-frequency drilling tasks on the job site.

This drill bit is suited for general metalworking, wood drilling, and multi-material applications in residential, commercial, and industrial settings. The impact-duty construction handles the torsional load of impact drivers without premature failure, while remaining compatible with standard drill chucks. Electricians, plumbers, HVAC technicians, and general contractors will find it effective for repetitive drilling in a range of substrates. Metric sizing makes it appropriate for metric fastener and fixture applications.

Key Features

• Titanium coating delivers up to 3 times the service life compared to black oxide drill bits
• Variable RED HELIX geometry with 35-degree to 15-degree transition promotes rapid chip removal and reduces heat buildup
• 135-degree split point tip starts on contact and prevents walking for accurate hole placement
• Impact-duty construction engineered to handle torsional stress from impact drivers and standard drills
• Integrated chip breaker design further limits heat accumulation during continuous drilling
• Metric sizing for metric-specification applications

Compatibility

Designed for use with standard drill chucks and hex-shank impact drivers across a wide range of drilling applications in wood, metal, and general multi-material substrates.

Installation Notes

Installation of this drill bit is performed by qualified tradespeople including electricians, plumbers, HVAC technicians, and general contractors. Ensure the drill or impact driver is powered off and the chuck is fully secured before beginning work. Use appropriate personal protective equipment including eye protection when drilling metal or other hard substrates. Do not exceed the tool manufacturer's recommended speed range for the material being drilled.
