Milwaukee Elec Tool 48-89-2304 Cobalt Drill Bit 7/64 in 5-pack

Product Description

The MILWAUKEE ELEC TOOL 48-89-2304 is a 7/64-inch cobalt twist drill bit sold in a 5-pack, engineered for hard metal drilling in professional trade and industrial applications. The variable helix design transitions from a 35-degree helix angle to 15 degrees, promoting efficient chip evacuation and reducing heat buildup during extended drilling cycles. A 135-degree split point tip starts on contact without center-punching and prevents the bit from walking on smooth or curved surfaces. Cobalt construction delivers superior heat resistance compared to standard high-speed steel, making this bit well-suited for stainless steel, hardened metals, PVC, and wood.

This bit is intended for electricians, plumbers, HVAC technicians, fabricators, and maintenance professionals who regularly drill into hard or abrasive materials. The enhanced tapered web strengthens the core and increases flute durability for sustained use in production or service environments. According to the manufacturer, this bit provides up to 15 times the service life of standard black oxide drill bits, reducing bit changes during repetitive drilling tasks on hard metal workpieces.

Compatibility

Designed as an OEM-style replacement or upgrade for standard 7/64-inch twist drill bits used in 3/8-inch or larger keyed and keyless drill chucks across corded and cordless drill drivers.

Installation Notes

This bit is installed by trade professionals using standard drill chucks; confirm the chuck accepts round-shank bits before use. Always secure the workpiece before drilling and wear appropriate eye protection. When drilling stainless steel or hardened metals, use a low speed setting and apply cutting fluid to extend bit life and manage heat. Disconnect power tools from their power source before changing bits.
