Eagle Cutting Tool 1080-056-D Hss Silver Deming Drill Bit

Product Description

The EAGLE CUTTING TOOL 1080-056-D is a 7/8-inch High-Speed Steel (HSS) Silver and Deming drill bit designed for heavy-duty metal drilling applications. The reduced 1/2-inch shank allows it to fit standard 1/2-inch drill chucks, making it compatible with common heavy-duty drill presses and handheld power drills. Manufactured in the USA, this bit is built for trade and industrial use where consistent performance in ferrous and non-ferrous metals is required. Machinists, millwrights, pipefitters, and maintenance technicians regularly reach for Silver and Deming bits when drilling oversized holes beyond the capacity of a standard jobber-length set.

Silver and Deming bits in the 7/8-inch diameter range are typically used for drilling through structural steel, pipe flanges, electrical enclosures, and similar metal substrates. This bit is suited for use on drill presses, magnetic-base drills, and heavy-duty corded drills in shop or field environments. It is a practical choice for trades that need to drill large-diameter holes without switching to a step bit or hole saw.

Key Features

• 7/8-inch cutting diameter for oversized hole drilling beyond standard jobber-bit range
• High-Speed Steel (HSS) construction for durability in metal drilling applications
• Reduced 1/2-inch shank fits standard 1/2-inch three-jaw drill chucks
• USA manufactured for consistent dimensional tolerances
• Silver and Deming geometry provides effective chip clearance in deep-hole drilling

Compatibility

Designed as an OEM-style replacement or direct-use Silver and Deming drill bit compatible with any 1/2-inch chuck-equipped drill press or heavy-duty power drill.

Installation Notes

Installation is performed by machinists, millwrights, or skilled tradespeople using a drill press or heavy-duty power drill equipped with a 1/2-inch chuck. Secure the workpiece firmly before drilling and use an appropriate cutting fluid or lubricant to extend bit life and improve cut quality in metal. Never exceed the recommended RPM range for the drill diameter and material being cut. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is present.
