Eagle Cutting Tool 1090-048-I Silver Deming Drill Bit

Product Description

The EAGLE CUTTING TOOL 1090-048-I is a 3/4-inch diameter high speed steel (HSS) Silver and Deming drill bit with a reduced 1/2-inch straight shank. Silver and Deming bits are designed specifically for drilling large-diameter holes in metal, where standard jobber-length bits are impractical. The reduced shank allows the bit to be chucked in a standard 1/2-inch drill press or handheld drill, making it a practical choice for machinists, maintenance technicians, pipefitters, and general metalworking tradespeople who need to bore oversized holes without a dedicated large-capacity chuck.

This bit is well suited for drilling through mild steel, aluminum, brass, and similar materials in fabrication shops, maintenance facilities, and on-site trade applications. It is an imported HSS Silver and Deming style, appropriate for general-purpose large-hole metalworking where production-grade carbide tooling is not required. Typical applications include conduit knockout enlargement, pipe flange work, sheet metal fabrication, and general metal drilling tasks where a 3/4-inch bore is needed.

Key Features

• 3/4-inch cutting diameter for large-hole metalworking applications
• 1/2-inch reduced straight shank fits standard 1/2-inch drill chucks
• High speed steel (HSS) construction for cutting mild steel, aluminum, and non-ferrous metals
• Silver and Deming style geometry provides stability and reduced chatter at large diameters
• Minimum order quantity of 1 — available as a single unit

Compatibility

Designed as a standard Silver and Deming replacement or general-use drill bit compatible with any drill press or handheld drill equipped with a 1/2-inch capacity chuck.

Installation Notes

Silver and Deming bits should be used in a drill press when possible to maintain proper alignment and reduce bit deflection at large diameters. Secure the workpiece firmly before drilling and apply cutting fluid to extend bit life and improve hole quality in ferrous materials. Inspect the cutting edges before use and do not operate a damaged or improperly sharpened bit. Always follow applicable shop safety practices and wear appropriate personal protective equipment.
