Milwaukee 48-89-2316 Cobalt Drill Bit 19/64 in 3 Pack

Product Description

The Milwaukee Electric Tool Corp 48-89-2316 is a cobalt drill bit designed for demanding metal drilling applications in trade and industrial environments. Sold in a 3-pack, each bit measures 19/64 inches in diameter and features a RED HELIX geometry intended to improve chip clearance and heat dissipation during high-speed drilling. Cobalt construction provides greater heat resistance than standard high-speed steel, making these bits well-suited for drilling through stainless steel, cast iron, and other hard ferrous metals. Electricians, plumbers, HVAC technicians, and fabricators reach for cobalt bits when standard bits fail or wear quickly on tough materials.

These bits are appropriate for both residential and commercial trade work where drilling into hard metals is routine. Typical applications include drilling through steel electrical enclosures, HVAC equipment panels, pipe flanges, structural steel, and hardware. The 3-pack format suits service technicians who carry spares or shops that cycle through drill bits at higher volume. Compatible with standard 3-jaw drill chucks on corded and cordless drills and drill presses.

Key Features

• Cobalt steel construction for elevated heat resistance and extended bit life in hard metals
• RED HELIX geometry promotes chip evacuation and reduces heat buildup at the cutting edge
• 19/64-inch diameter for precise hole sizing in metal fabrication and trade installations
• Sold as a 3-pack for backup availability on the job or in the shop
• Compatible with standard 3-jaw drill chucks on common corded and cordless platforms

Compatibility

Designed as a standard shank cobalt drill bit compatible with 3-jaw drill chucks on corded drills, cordless drills, and drill presses accepting 19/64-inch round shank tooling.

Installation Notes

Cobalt drill bits are installed by licensed electricians, HVAC technicians, plumbers, and pipefitters as part of routine metal drilling tasks. Secure the workpiece firmly before drilling and use cutting fluid or a cooling lubricant when drilling through thick or hardened steel to extend bit life. Wear appropriate eye protection and gloves. Inspect each bit for chips or cracks before use and discard damaged bits immediately.
