Product Description

The EAGLE CUTTING TOOL 1080D-039-D is a 39/64-inch diameter Dyno SD twist drill bit with a 1/2-inch straight shank and a bright gold finish. Manufactured in the USA, this bit is built for professionals who need consistent cutting performance in metal, wood, or composite materials. The bright gold coating helps reduce friction and extends bit life under repeated use. Weighing 0.69 pounds, it is a solid, job-site-ready tool suited for machinists, pipefitters, plumbers, and electricians who drill large-diameter pilot or clearance holes as part of their trade work.

The 1080D-039-D is designed for use in stationary drill presses or heavy-duty handheld drills with a 1/2-inch chuck. The 39/64-inch cutting diameter is a common size for clearance holes, conduit knock-outs, and through-hole applications in steel plate, structural iron, copper, aluminum, and similar materials. Its straight 1/2-inch shank provides a secure grip in standard 1/2-inch chucks without the need for adapters, making it a practical choice for industrial and commercial trade applications.
