Milwaukee 48-89-2754 Silver Deming Drill Bit 1 Inch

Product Description

The Milwaukee Electric Tool Corp 48-89-2754 is a 1-inch Silver Deming drill bit with a black oxide coating, designed for general-purpose drilling in wood and metal. Silver Deming bits feature a reduced 1/2-inch shank, allowing them to be chucked in standard 1/2-inch drill presses and heavy-duty hand drills when a full-diameter shank is not practical. The black oxide surface treatment reduces friction during cutting and provides a basic level of corrosion resistance, extending service life in typical shop and field conditions. This bit ships in a square sleeve case and is sold as a single unit.

This drill bit suits residential and light commercial applications where large-diameter holes are required in wood framing, steel plate, or similar materials. Typical install scenarios include HVAC rough-in, plumbing penetrations, electrical trade work, and general fabrication tasks. The 1-inch cutting diameter makes it a practical choice for conduit knockouts, pipe clearance holes, and anchor bolt passages in both new construction and retrofit work.

Key Features

• 1-inch cutting diameter for large-bore drilling in wood and metal
• Black oxide coating reduces friction and provides anti-corrosive protection
• Reduced 1/2-inch shank fits standard 1/2-inch drill chucks
• Square sleeve case included for organized storage and transport
• Suitable for general-purpose use across multiple trade disciplines

Compatibility

Designed for use in standard 1/2-inch keyed or keyless drill chucks found on drill presses and heavy-duty corded or cordless hand drills.

Installation Notes

This bit is installed and operated by any trade professional requiring large-diameter holes in wood or metal substrates. Secure the workpiece before drilling and use appropriate cutting fluid when drilling through ferrous metal to reduce heat buildup and extend bit life. Always verify chuck capacity before mounting a Silver Deming bit, as the reduced shank must be fully seated and tightened in the chuck jaws. Wear appropriate eye protection in accordance with applicable jobsite safety requirements.
