Milwaukee 48-89-4819 Shockwave Titanium Jobber Drill Bit

Product Description

The MILWAUKEE 48-89-4819 is a titanium-coated jobber length drill bit engineered for use with both impact drivers and standard drills. It features a variable RED HELIX design with an aggressive 35-degree helix angle that transitions to 15 degrees, promoting rapid chip removal and reducing heat buildup during extended drilling cycles. The 135-degree split point tip starts on contact without walking, delivering accurate, clean holes across a range of materials. The titanium coating extends service life compared to standard black oxide bits. Licensed HVAC, plumbing, and electrical trades regularly reach for impact-rated bits like this one during rough-in and service work.

This bit is suited for residential and commercial jobsite applications where an impact driver or corded drill is the primary tool. The impact-duty construction handles the rotational shock loads produced by impact drivers without premature failure. Metric sizing on this bit accommodates metric fastener pilot holes and metric hardware installations common in equipment servicing and panel work. The chip breaker geometry helps maintain cutting performance in steel, aluminum, wood, and composite materials encountered across trade work.

Key Features

• Titanium coating for extended service life compared to black oxide drill bits
• Variable RED HELIX geometry with 35-degree to 15-degree transition for rapid chip evacuation
• 135-degree split point tip for precise, no-walk starts
• Impact-duty rated construction compatible with both impact drivers and standard drills
• Chip breaker design reduces heat buildup during continuous drilling
• Metric sizing for metric pilot hole and hardware applications

Compatibility

Designed as an impact-duty replacement or addition for use in standard drill chucks and impact driver hex chuck configurations across residential and commercial trade applications.

Installation Notes

Installation of this bit requires securing it firmly in the tool chuck before operation to prevent slippage or runout. Always wear appropriate eye protection when drilling metal or composite materials. Ensure the workpiece is clamped or otherwise secured before drilling to prevent movement. Follow applicable OSHA and site-specific safety requirements when operating power tools on commercial or industrial jobsites.
