Milwaukee 48-89-4807 Titanium Jobber Drill Bit Impact Duty

Product Description

The MILWAUKEE 48-89-4807 is a titanium-coated jobber length drill bit engineered for use with both impact drivers and standard drills. 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 to extend cutting life. The 135-degree split point tip starts on contact without walking, delivering fast, accurate holes. Licensed tradespeople and contractors working in metal, wood, or general-purpose drilling applications rely on this bit for consistent performance across demanding jobsite conditions.

This bit is suited for residential and commercial construction, mechanical, and fabrication work where metric-sized holes are required. The titanium coating is effective across all standard drilling applications and is rated to deliver up to 3 times the service life compared to black oxide drill bits. It is sold individually and sized for use in standard chuck-equipped drills and impact drivers.

Key Features

• Titanium coating provides up to 3x service life versus black oxide drill bits
• Variable helix design transitions from 35 degrees to 15 degrees for rapid chip removal and reduced heat buildup
• 135-degree split point tip for precise starts and no walking
• Impact duty construction rated for use with both impact drivers and standard drills
• Metric sizing for metric-dimension hole requirements
• Chip breaker geometry further reduces heat accumulation during extended drilling

Compatibility

Designed as an OEM-style jobber length drill bit compatible with standard 3-jaw chuck drills and hex-shank impact drivers used in construction, mechanical, and fabrication trades.

Installation Notes

Secure the bit fully in the chuck or impact driver before use and verify it is seated straight to avoid runout. Always wear appropriate eye protection when drilling. Use the appropriate drill speed for the material being drilled to avoid premature coating wear. Inspect the tip for wear or chipping before each use and replace if the split point is damaged.
