Eagle Cutting Tool C1080-045-D Cobalt Drill Bit 45/64 in

Product Description

The EAGLE CUTTING TOOL C1080-045-D is a 45/64 inch cobalt screw machine (stub length) drill bit with a 1/2 inch reduced shank, manufactured in the USA. Cobalt high-speed steel construction provides superior heat and wear resistance compared to standard HSS bits, making it well suited for drilling through tough materials including stainless steel, cast iron, titanium, and high-nickel alloys. The stub length body reduces deflection and increases rigidity in tight clearance applications. This bit is used by machinists, maintenance technicians, and industrial tradespeople who require consistent hole quality at elevated cutting speeds.

The C1080-045-D is designed for use in drill presses, CNC machining centers, and hand-held industrial drills equipped with a 1/2 inch chuck. The 1/2 inch reduced shank allows this larger-diameter bit to seat in standard 1/2 inch capacity chucks without requiring a larger spindle. Typical applications include metal fabrication shops, maintenance and repair operations, and production drilling in industrial and commercial settings where hard or abrasive materials are encountered regularly.

Key Features

• 45/64 inch cutting diameter for precise hole sizing in metal applications
• Cobalt HSS construction resists heat buildup during prolonged or high-speed drilling
• 1/2 inch reduced shank fits standard 1/2 inch drill chucks
• Stub length body increases rigidity and reduces bit deflection
• Made in the USA

Compatibility

Designed as an OEM-style replacement or direct-use drill bit for any drill press, machining center, or industrial hand drill with a 1/2 inch or larger chuck capacity.

Installation Notes

Secure the 1/2 inch shank firmly in the chuck before operation and verify the bit is fully seated with no runout. Use appropriate cutting fluid or coolant when drilling hardened or stainless steel to extend tool life and maintain hole quality. Wear appropriate eye and hand protection per standard shop safety practices. Inspect the cutting edges for wear or chipping before each use and remove the bit from service if edge damage is observed.
