Milwaukee 48-89-2314 Cobalt Drill Bit 17/64 in 3-pack

Product Description

The Milwaukee Electric Tool Corp 48-89-2314 is a cobalt drill bit designed for drilling through hard metals, stainless steel, cast iron, and other demanding materials encountered in mechanical, plumbing, and electrical trade work. The RED HELIX geometry promotes faster chip evacuation and reduced heat buildup during extended drilling cycles. At 17/64 inches in diameter, this bit fills a common size requirement for bolt clearance holes, conduit knockouts, and pipe hanger applications. Each package contains 3 bits, giving installers ready replacements on the job without a supply run. Cobalt construction provides greater heat resistance than standard high-speed steel, extending service life in high-friction drilling conditions.

This drill bit is suited for use in residential and commercial trade applications where metal drilling is routine. Electricians drilling panel enclosures, plumbers working through metal framing, and HVAC techs mounting equipment to steel brackets will find the 17/64-inch diameter useful for standard fastener clearance. The 3-piece pack is practical for service vans and tool bags where bit attrition is a regular occurrence.

Installation Notes

Cobalt drill bits are installed by licensed tradespeople and experienced mechanics using standard drill chucks. Always center-punch the workpiece before drilling to prevent bit walking on smooth metal surfaces. Use appropriate cutting fluid on stainless steel and hardened materials to extend bit life and reduce heat. Wear appropriate eye protection and secure the workpiece before drilling.
