Milwaukee 48-89-2311 Cobalt Drill Bit 7/32 in 5 Pack

Product Description

The Milwaukee Electric Tool Corp 48-89-2311 is a 7/32 inch cobalt drill bit sold in a 5-pack, built for professionals who drill through hard metals, stainless steel, cast iron, and other tough materials on the job. The RED HELIX geometry is designed to maximize speed and life in demanding applications by reducing heat buildup during drilling. At 0.21 pounds for the pack, these bits are a practical addition to any drill kit used in metalworking, mechanical, electrical, or HVAC service work where accurate, clean holes in hard substrates are required.

These cobalt bits are suited for trade professionals in electrical, HVAC, plumbing, and general mechanical work who regularly need to drill through metal framing, brackets, enclosures, and equipment panels. The 7/32 inch diameter is a commonly used size for pilot holes, fastener clearance, and conduit or tubing applications. The 5-pack format reduces downtime by keeping spare bits on hand during continuous production or service work.

Key Features

• 7/32 inch diameter cobalt construction for drilling hard metals and alloys
• RED HELIX design reduces heat and improves chip evacuation during use
• Sold in a 5-pack for extended field use without restocking
• Cobalt material provides greater heat resistance than standard high-speed steel bits

Compatibility

Designed for use with standard 3/8 inch and 1/2 inch keyed or keyless drill chucks compatible with round-shank twist drill bits. Suitable for use in corded and cordless drills commonly used in HVAC, electrical, and mechanical trade applications.

Installation Notes

Cobalt drill bits should be installed in a properly tightened chuck before use to prevent slippage and bit damage. Always wear eye protection when drilling metal, and use cutting oil or lubricant when drilling stainless steel or hardened alloys to extend bit life. Secure the workpiece firmly before drilling to prevent movement and ensure a clean, accurate hole. Disconnect power to the drill before changing bits.
