Eagle Cutting Tool 1090-111-I Hss Silver Deming Drill Bit

Product Description

The EAGLE CUTTING TOOL 1090-111-I is a high-speed steel (HSS) Silver and Deming drill bit with a 1-11/64 inch cutting diameter and a reduced 1/2 inch straight shank. Silver and Deming bits are designed with a full-size cutting head and a reduced shank so they can be chucked in standard 1/2 inch drill chucks, making large-diameter drilling accessible without a dedicated large-capacity machine. This bit is suited for metalworking, fabrication, and general industrial drilling tasks where oversized holes are required in steel, aluminum, cast iron, and similar materials.

This drill bit is used in metal fabrication shops, maintenance and repair operations, and industrial service environments. The 1-11/64 inch diameter is a common size for bolt clearance holes, bushing seats, and conduit knockout applications. It is typically installed and operated by machinists, millwrights, pipefitters, and electricians working with drill presses or heavy-duty hand drills equipped with a 1/2 inch chuck.

Installation Notes

This bit is installed and operated by qualified machinists or trade professionals.
