Eagle Cutting Tool 1080-040-D Hss Silver Deming Drill Bit

Product Description

The EAGLE CUTTING TOOL 1080-040-D is a Silver and Deming high-speed steel (HSS) drill bit designed for drilling large-diameter holes in metal, wood, and other hard materials. With a 5/8 inch cutting diameter and a reduced 1/2 inch shank, it fits standard 1/2 inch drill chucks without requiring a larger capacity machine. This bit is manufactured in the USA and is a go-to choice for machinists, pipefitters, electricians, and general trade professionals who need reliable performance when drilling oversized holes on the job.

Silver and Deming bits are commonly used in industrial and commercial settings where full-size drill presses or heavy-duty hand drills are in use. The reduced shank design makes this 5/8 inch bit accessible to a wide range of equipment. Typical applications include drilling clearance holes for conduit, pipe hangers, structural connections, and metal fabrication work where twist drills in standard sizes fall short.

Installation Notes

This bit is installed and used by machinists, electricians, pipefitters, and general tradespeople operating drill presses or heavy-duty corded drills. Secure the 1/2 inch shank firmly in the chuck before operation and verify the workpiece is clamped or fixtured to prevent movement. Use appropriate cutting fluid when drilling steel or hard metals to extend bit life and improve cut quality. Inspect the cutting edges before each use and remove the bit from service if chipping or excessive wear is observed.
