Milwaukee 48-89-4804 Titanium Jobber Drill Bit Metric

Product Description

The MILWAUKEE 48-89-4804 is a titanium-coated jobber length drill bit engineered for use with both standard drills and impact drivers. It features a variable helix design with an aggressive 35-degree angle that transitions to a 15-degree angle, promoting rapid chip evacuation and reducing heat buildup at the cutting zone. The 135-degree split point tip provides a precise, self-centering start that prevents walking on the workpiece. This bit is sized to metric specifications and suited for everyday drilling in metal, wood, and general-purpose materials. Installers, maintenance technicians, and trade professionals who run impact drivers on the job will find this bit built to handle the torque and vibration those tools generate.

This drill bit is intended for jobsite and shop use across trades including electrical, plumbing, HVAC, and general construction. The titanium coating extends service life, delivering up to 3 times the longevity compared to standard black oxide bits under comparable drilling conditions. Metric sizing makes it a practical choice for applications requiring metric hole diameters. The bit is sold individually and is compatible with standard drill chucks and impact-rated quick-change chuck systems that accept round-shank jobber bits.

Key Features

• Titanium coating rated for up to 3 times the service life of black oxide drill bits
• Variable helix design transitions from 35 degrees to 15 degrees for rapid chip removal and reduced heat
• 135-degree split point tip for a precision, no-walk start
• Impact duty construction engineered to withstand torque and vibration from impact drivers
• Metric sizing for metric-dimensioned hole requirements
• Jobber length profile suited to general-purpose drilling depth

Compatibility

Designed for use with standard keyed and keyless drill chucks as well as impact-rated chuck systems that accept round-shank jobber length drill bits.

Installation Notes

Install and remove drill bits only when the tool is powered off and the chuck is fully stopped. Secure the bit fully in the chuck before operating to prevent slippage and reduce runout. When drilling metal, use appropriate cutting fluid where applicable to extend bit life and improve hole quality. Inspect the bit tip for wear or chipping before each use and replace if the cutting edges are degraded.
