Milwaukee 48-89-4805 Titanium Jobber Drill Bit Impact Duty

Product Description

The MILWAUKEE 48-89-4805 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 removal and limiting heat buildup to extend cutting life. A 135-degree split point tip delivers a precise start and eliminates walking on entry. The titanium coating provides up to 3 times the service life compared to black oxide drill bits. This bit is sold individually and suited for professionals who demand consistent performance across high-volume drilling tasks.

This drill bit is designed for metric-sized applications and fits standard jobber length drilling scenarios in construction, mechanical, and fabrication work. The impact-duty shank geometry makes it compatible with impact drivers as well as corded and cordless drills. The variable helix and chip breaker geometry reduce friction and heat in both wood and metal substrates, making it a practical choice for electricians, plumbers, HVAC technicians, and general contractors who drill frequently on the job site.

Key Features

• Titanium coating delivers up to 3 times the life compared to black oxide drill bits
• Variable helix transitions from 35 degrees to 15 degrees for rapid chip removal
• 135-degree split point tip prevents walking and ensures accurate hole starts
• Chip breaker geometry reduces heat buildup during extended use

Compatibility

Designed as an impact-duty replacement or upgrade drill bit compatible with standard hex-shank impact drivers and 3-jaw chuck drills used in typical trade and jobsite applications.

Installation Notes

This bit is installed and removed by a licensed tradesperson or experienced operator using a standard drill chuck or hex-shank impact driver collet. Ensure the driver or drill is powered off and the bit is fully seated before beginning work. Allow the bit to cool between extended drilling cycles to preserve coating integrity. Follow applicable safety codes and wear appropriate eye protection when drilling.
