Milwaukee 48-89-4806 Shockwave Titanium Drill Bit

Product Description

The MILWAUKEE 48-89-4806 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, accelerating chip evacuation and reducing heat buildup during continuous drilling. The 135-degree split point tip starts on contact without walking, delivering clean, accurate holes across a wide range of materials. The titanium coating extends service life significantly compared to standard black oxide bits. This bit is sized in metric and sold individually. It is suited for electricians, plumbers, HVAC technicians, and general trade professionals who drill frequently with impact drivers or drill-drivers on the job.

The 48-89-4806 is intended for jobsite drilling applications in metal, wood, plastic, and composite materials. The SHOCKWAVE-series construction handles the high-torque output of impact drivers without the tip deformation or shank failure common in standard jobber bits. The variable RED HELIX geometry actively clears chips from the flutes, keeping the cutting edge cooler and maintaining cutting efficiency through longer run times. Metric sizing makes this bit appropriate for fastener and fixture applications requiring metric hole diameters.

Key Features

• Titanium coating provides up to 3X service life compared to black oxide drill bits
• Variable helix transitions from 35 degrees to 15 degrees for rapid chip removal and reduced heat
• 135-degree split point starts on contact and prevents bit walking
• Impact-duty construction engineered for use with both impact drivers and standard drills
• Metric sizing for metric-specification drilling applications
• Sold individually (each)

Compatibility

Designed as an impact-duty replacement or addition for trade professionals using standard 3/8-inch or 1/2-inch chuck drills and hex-shank-compatible impact drivers requiring metric jobber-length drill bits.

Installation Notes

Installation of this bit requires a compatible chuck or hex-shank adapter rated for the torque output of the tool in use. Secure the bit fully in the chuck before drilling and verify chuck key removal where applicable. Always wear appropriate eye protection when drilling. Reduce feed pressure when breaking through the back side of a workpiece to maintain hole quality and bit life.
