Eagle Cutting Tool 1090-123-I Hss Silver Deming Drill Bit

Product Description

The EAGLE CUTTING TOOL 1090-123-I is a high-speed steel (HSS) Silver Deming drill bit sized at 1-23/64 inches with a reduced 1/2-inch shank. Silver Deming bits are designed to drill large-diameter holes in metal, wood, and plastic using a standard 1/2-inch drill chuck, eliminating the need for a larger Jacobs-style chuck. This bit is suited for HVAC technicians, plumbers, electricians, and sheet metal workers who need to bore oversized holes through structural materials, equipment panels, or pipe penetrations. The HSS construction provides durability across a wide range of materials encountered in trade work.

This drill bit is intended for use in residential and commercial trade applications where large-diameter holes are required and access is limited to a standard 1/2-inch chuck drill or drill press. Typical uses include boring holes for conduit, pipe, or duct fittings through wood framing, steel panels, and similar substrates. The reduced shank design makes it compatible with widely available equipment already on the job site.
