Eagle Cutting Tool 1090-121-I Hss Silver Deming Drill Bit

Product Description

The EAGLE CUTTING TOOL 1090-121-I is a high-speed steel (HSS) Silver and Deming drill bit designed for drilling large-diameter holes in metal, wood, and other industrial materials. With a 1-21/64 inch cutting diameter and a reduced 1/2 inch shank, this bit fits standard 1/2 inch drill chucks without requiring a larger capacity machine. Silver and Deming style bits are a common choice for machinists, maintenance technicians, and fabricators who need oversized bore capability from conventional equipment. The HSS construction provides solid cutting performance across a wide range of workpiece materials encountered in trade and industrial applications.

This drill bit is suited for use in metal fabrication shops, maintenance and repair operations, and general industrial settings where large-diameter holes are required. The reduced shank design allows the bit to be used in standard 1/2 inch capacity drill presses, magnetic base drills, and portable power drills. It is a practical solution for applications where step drilling or hole saws are not preferred and a clean, single-pass bore is needed.

Key Features

• 1-21/64 inch cutting diameter for large-bore applications
• Reduced 1/2 inch shank fits standard 1/2 inch drill chucks
• High-speed steel (HSS) construction for durability across common workpiece materials

Compatibility

Designed as a standard Silver and Deming style replacement or addition for use with 1/2 inch chuck drill presses, magnetic base drills, and portable power drills requiring a large-diameter HSS drill bit.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with large-diameter drilling operations. Secure the workpiece firmly before drilling and use appropriate cutting fluid to extend bit life and improve cut quality. Verify that the drill chuck is properly tightened on the 1/2 inch shank before operation. Follow all applicable workplace safety guidelines and equipment manufacturer recommendations when operating drill presses or portable power tools.
