Milwaukee 48-89-4617 5/16 in Titanium Drill Bit 3-pack

Product Description

The Milwaukee Electric Tool Corp 48-89-4617 is a 5/16-inch titanium-coated impact duty drill bit engineered for use with impact drivers. Part of the Shockwave line, it features a variable helix design with an aggressive 35-degree helix angle that transitions to 15 degrees at the tip. This geometry promotes rapid chip evacuation, reducing heat buildup so the cutting edge stays sharp through repeated use. The 135-degree split point tip starts on contact without walking, delivering fast, accurate holes. Sold in a 3-pack, this bit suits high-volume drilling tasks on job sites where durability and throughput matter.

These impact duty titanium drill bits are intended for trade professionals and skilled tradespeople who rely on impact drivers as primary drilling tools. The titanium coating is rated for use across a broad range of drilling applications, including wood, metal, and plastics. The Red Helix design is optimized to handle the high-torque, high-vibration output of impact drivers without premature wear or breakage, making it a practical choice for carpenters, electricians, plumbers, and general contractors running production work.

Key Features

• Variable helix with 35-degree aggressive angle transitioning to 15 degrees for rapid chip removal
• 135-degree split point tip prevents walking and starts holes precisely without a center punch
• Titanium coating provides up to 3 times longer life compared to black oxide drill bits
• Engineered specifically for impact drivers to handle high-torque, high-vibration conditions
• Sold as a 3-pack for job site redundancy and extended service life

Compatibility

Designed as an OEM-style impact duty replacement bit compatible with standard hex-shank impact drivers used in residential and commercial construction applications.

Installation Notes

Installation of this bit requires a compatible impact driver with a standard hex chuck. Ensure the driver is powered off and the chuck is fully released before inserting or removing the bit. Use appropriate personal protective equipment including eye protection when drilling. Follow applicable worksite safety codes for tool use and material handling.
