Milwaukee 48-89-4816 Titanium Jobber Drill Bit 135 Split Point

Product Description

The MILWAUKEE 48-89-4816 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 15 degrees, promoting rapid chip removal and limiting heat buildup during continuous drilling. The 135-degree split point tip provides a self-centering start and eliminates walking on smooth or curved surfaces. The titanium coating delivers extended service life compared to standard black oxide bits, making this bit a practical choice for metal fabrication, mechanical, and general trade work where tool longevity matters.

This drill bit is suited for residential and commercial jobsite applications where professionals need a bit that transitions between a standard drill and an impact driver without swapping tools. The variable helix geometry helps maintain cutting efficiency across a range of materials including steel, aluminum, wood, and plastics. Metric sizing is available in this product line, and the bit is sold individually, making it straightforward to replace a single worn bit in a set.

Key Features

• Titanium coating for up to 3X service life compared to black oxide drill bits
• Variable helix design transitions from 35 degrees to 15 degrees for rapid chip evacuation
• 135-degree split point tip self-centers and prevents walking for accurate hole starts
• Compatible with both standard drills and impact drivers
• Chip breaker geometry reduces heat buildup during extended drilling
• Metric sizing available in this series

Compatibility

Designed as a direct-fit replacement jobber-length drill bit compatible with standard three-jaw drill chucks and impact driver bit holders used in general trade and mechanical applications.

Installation Notes

Installation of this drill bit requires securing it fully into the drill chuck or impact driver bit holder before operation. Ensure the workpiece is clamped or secured before drilling to maintain accuracy and operator safety. Use appropriate cutting fluid when drilling ferrous metals to preserve coating life and reduce heat. Follow applicable jobsite safety protocols and wear eye protection during all drilling operations.
