Milwaukee 48-89-4813 Shockwave Titanium Drill Bit Metric

Product Description

The MILWAUKEE 48-89-4813 is a titanium-coated jobber length drill bit engineered for use with both impact drivers and standard drills. It features a variable helix design with an aggressive 35-degree helix angle that transitions to 15 degrees, promoting rapid chip evacuation and reducing heat buildup during extended drilling. The 135-degree split point tip starts precisely without walking, making it well suited for production drilling in metal and other common materials. The titanium coating extends service life significantly compared to standard black oxide bits. Licensed trades and general contractors use this bit for everyday hole-making on the job site.

This drill bit is intended for metric-sized applications and covers a wide range of general drilling tasks including metal, wood, and plastic substrates. It is sized and packaged as a single unit, making it a practical add-on replacement for worn bits in an existing set. The impact-duty construction allows it to handle the rotational stress and shock loads produced by impact drivers without premature breakage or tip failure, giving it versatility across job site conditions.

Key Features

• Titanium coating delivers up to 3x service life compared to black oxide drill bits
• Variable RED HELIX design with 35-degree to 15-degree angle transition for rapid chip removal
• 135-degree split point tip provides a precise start and prevents walking
• SHOCKWAVE impact-duty construction engineered to withstand shock loads from impact drivers
• CHIP BREAKER geometry reduces heat buildup during continuous drilling
• Metric sizing for metric-dimensioned hole requirements

Compatibility

Designed for use with standard 3-jaw drill chucks and hex-shank impact drivers accepting jobber length drill bits in metric sizing.

Installation Notes

This bit is installed and removed by a licensed electrician, plumber, carpenter, or general trades worker depending on the application. Secure the bit firmly in the chuck or impact driver collet before operation. When drilling metal, use appropriate cutting fluid to extend bit life and reduce heat. Inspect the split point tip before each use and replace the bit if the tip shows chipping or wear that would affect starting accuracy.
