Eagle Cutting Tool 1090D-060-I Dyno Sd Drill Bit 15/16 in

Product Description

The EAGLE CUTTING TOOL 1090D-060-I is a Dyno SD bright ground drill bit engineered for demanding metal drilling applications. Sized at 15/16 inch with a 1/2 inch shank, this bit is built for use in heavy-duty drilling operations where consistent hole quality and cutting performance are required. The bright ground finish indicates an uncoated, precision-ground cutting edge suited for general-purpose drilling in steel, iron, and similar materials. Machinists, tool-and-die workers, and maintenance technicians rely on bits in this class for accurate, repeatable results across production and repair environments.

This drill bit is appropriate for use in stationary drill presses, milling machines, and heavy-duty hand drilling equipment capable of accepting a 1/2 inch shank. The 15/16 inch diameter makes it well suited for through-hole drilling, reaming prep work, and enlarging existing bores in ferrous and non-ferrous metals. It is also used in fabrication shops and maintenance facilities where larger-diameter drilling is routine.

Compatibility

Designed as an OEM-style replacement and direct-fit cutting tool for drill presses, milling machines, and heavy-duty hand drills equipped with a 1/2 inch chuck or collet capable of accepting the specified shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or experienced technician familiar with rotating cutting tools. Ensure the drill chuck or collet is fully tightened and the workpiece is securely clamped before beginning any drilling operation. Always use appropriate cutting fluid or lubricant when drilling ferrous metals to extend tool life and improve hole finish. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed settings.
