Milwaukee 48-89-4823 Shockwave Titanium Jobber Drill Bit

Product Description

The MILWAUKEE 48-89-4823 is a titanium-coated jobber length drill bit engineered for use with both impacts 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 continuous drilling. A 135-degree split point tip delivers a precise start and eliminates walking on hard surfaces. The titanium coating extends service life significantly compared to standard black oxide bits, making this a working tool for high-volume drilling tasks on the jobsite. Licensed HVAC, electrical, and plumbing tradespeople commonly carry these bits for everyday metal and material drilling applications.

This bit is suited for a wide range of drilling applications including metal, wood, and composite materials in residential and light commercial trade work. The SHOCKWAVE design absorbs torque from impact drivers, reducing bit breakage under high-cycle conditions. The metric sizing makes it appropriate for applications requiring metric hole dimensions. The RED HELIX geometry channels chips away from the cutting zone, maintaining cut efficiency through longer run times without manual clearing.

Key Features

• Titanium coating delivers up to 3X service life compared to black oxide drill bits
• Variable RED HELIX design: 35-degree helix transitions to 15 degrees for rapid chip removal
• 135-degree split point tip for precise starts with no walking
• SHOCKWAVE impact-duty construction engineered for both impacts and standard drills
• Chip breaker geometry reduces heat buildup during extended drilling cycles
• Metric sizing for metric hole dimension applications

Compatibility

Designed for use with standard impact drivers and corded or cordless drills accepting jobber length bits. Suitable for drilling metal, wood, and composite materials across general trade applications.

Installation Notes

Insert the bit fully into the chuck or quick-change holder and confirm it is seated and locked before operation. Always wear appropriate eye protection when drilling. Match drill speed to the material being drilled — lower RPM for harder metals, higher RPM for softer materials. Inspect the cutting tip for wear regularly; a dull bit generates excess heat and reduces hole quality.
