Eagle Cutting Tool 1080-037-D Hss Silver Deming Drill Bit

Product Description

The EAGLE CUTTING TOOL 1080-037-D is a 37/64-inch high-speed steel (HSS) Silver Deming drill bit with a reduced 1/2-inch straight shank. Silver Deming bits are designed for drilling larger-diameter holes in metal, wood, and plastic where standard jobber-length bits cannot be chucked in a 3/8-inch or smaller drill. The 1/2-inch shank allows the bit to seat securely in any 1/2-inch drill chuck, making it a common choice for electricians, plumbers, HVAC technicians, and general-trade mechanics who need to bore oversized holes through structural members, enclosures, or pipe penetrations.

This bit is manufactured in the USA and suited for use in both shop and field environments. It fits standard 1/2-inch keyed or keyless drill chucks found on corded and heavy-duty cordless drills. Silver Deming geometry — with a full-diameter cutting end and reduced shank — is a widely adopted format for trade professionals who need to keep a compact set of large-diameter bits without purchasing a full set of matching chuck sizes. Typical applications include conduit knockouts, pipe rough-in, bracket mounting, and sheet-metal fabrication.

Key Features

• 37/64-inch cutting diameter for oversized hole applications
• High-speed steel (HSS) construction for durability across metal, wood, and plastic
• Reduced 1/2-inch straight shank fits standard 1/2-inch drill chucks
• Silver Deming style allows large-diameter drilling without a large-shank chuck
• Made in the USA

Compatibility

Designed for use with any drill or drill press equipped with a 1/2-inch chuck. Suitable for drilling metal, wood, and plastic in residential and light commercial trade applications.

Installation Notes

Seat the 1/2-inch shank fully into the chuck and tighten securely before drilling. Use appropriate cutting fluid or lubricant when drilling through ferrous metals to extend bit life and reduce heat buildup. Wear eye protection and secure the workpiece before operation. For drill press use, set spindle speed appropriate to the material and bit diameter per standard machining guidelines.
