Eagle Cutting Tool 1080-048-D Silver Deming Drill Bit 3/4 in

Product Description

The EAGLE CUTTING TOOL 1080-048-D is a 3/4-inch High Speed Steel (HSS) Silver and Deming drill bit with a reduced 1/2-inch shank. Silver and Deming bits are designed with a full-size cutting diameter paired with a reduced shank so the bit fits standard 1/2-inch chuck capacity drills and drill presses. This bit is manufactured in the USA and suited for drilling through ferrous metals, non-ferrous metals, and a range of industrial materials. Machinists, pipefitters, electricians, and maintenance technicians reach for this style of bit when a standard jobber-length drill will not achieve the required hole diameter.

This bit is used in metal fabrication shops, mechanical rooms, and field service applications where holes larger than 1/2 inch are required without a dedicated large-capacity chuck. Common applications include drilling knock-outs in enclosures, enlarging conduit holes, pipe fitting layout work, and general structural fabrication. The 1/2-inch reduced shank makes it compatible with widely available corded drills and benchtop drill presses already present in most trade shops.

Key Features

• 3/4-inch cutting diameter for oversized hole work beyond standard jobber-length capacity
• 1/2-inch reduced shank fits standard 1/2-inch chuck drills and drill presses
• High Speed Steel construction handles ferrous and non-ferrous metal drilling
• USA manufactured for consistent geometry and heat treatment quality
• Silver and Deming design provides stable, centered entry on flat and curved stock

Compatibility

Designed as a direct-fit replacement for standard 3/4-inch Silver and Deming drill bits with 1/2-inch reduced shanks used in 1/2-inch chuck capacity corded drills and drill presses.

Installation Notes

Secure the 1/2-inch shank firmly in a properly functioning 1/2-inch keyed or keyless chuck before use. Use appropriate cutting fluid when drilling through ferrous metals to extend bit life and reduce heat buildup. Clamp the workpiece securely and apply steady, moderate feed pressure — forcing the bit increases heat and accelerates edge wear. Inspect the cutting edges before each use and replace the bit if chipping or significant dulling is present.
