Eagle Cutting Tool C1090-063-I Cobalt Silver Deming Drill

Product Description

The EAGLE CUTTING TOOL C1090-063-I is a cobalt silver deming drill bit sized at 63/64 inches with a reduced 1/2-inch shank. Cobalt construction gives this bit the heat resistance and hardness needed to cut through tough materials including stainless steel, cast iron, hardened alloys, and other hard-to-drill metals. The reduced shank allows the bit to be chucked in standard 1/2-inch capacity drill presses and hand drills without requiring a larger chuck. This bit is suited for machinists, fabricators, pipefitters, and other trades that routinely drill oversized holes in hard material.

Silver deming style drill bits are a go-to solution when a standard jobber-length bit is too short or when a reduced shank is needed to access a 1/2-inch chuck for large-diameter drilling. This bit is appropriate for use in drill presses, magnetic drills, and heavy-duty hand drills in industrial, manufacturing, and mechanical trade settings where large-diameter holes are required through metal stock, plate, or structural material.

Key Features

• 63/64-inch cutting diameter for large-bore hole applications
• 1/2-inch reduced shank fits standard 1/2-inch drill chucks
• Cobalt construction provides superior heat resistance for drilling hard metals
• Silver deming geometry designed for controlled, accurate large-diameter drilling
• Minimum order quantity of 1 unit

Compatibility

Designed as a replacement or supplemental large-diameter cobalt drill bit compatible with any drill press or heavy-duty drill accepting a 1/2-inch round shank bit.

Installation Notes

This bit is installed and operated by machinists, fabricators, and trade professionals using drill presses or magnetic base drills. Always secure the workpiece firmly before drilling and use appropriate cutting fluid when drilling hard or stainless alloys to extend bit life and maintain cut quality. Inspect the bit for wear or chipping before each use. Do not exceed the recommended RPM range for the cutting diameter on the drill press being used.
