Eagle Cutting Tool C1080-049-D Cobalt Drill 49/64 in

Product Description

The EAGLE CUTTING TOOL C1080-049-D is a cobalt screw machine (stub length) drill bit sized at 49/64 inches in diameter with a 1/2-inch reduced shank. Cobalt construction gives the bit increased heat resistance and hardness compared to standard high-speed steel, making it well suited for drilling through tough ferrous metals, stainless steel, cast iron, and hard alloys. The stub-length body is shorter and more rigid than a jobber-length bit, reducing deflection and chatter in production drilling applications. This bit is manufactured in the USA.

This drill bit is used in manufacturing, maintenance, and fabrication environments where hole accuracy and tool longevity matter. The reduced 1/2-inch shank allows it to seat in standard 1/2-inch drill chucks and machine spindles without requiring a specialty collet or adapter. Typical applications include metalworking, structural fabrication, and toolroom work where operators are drilling into hard or abrasive base materials.

Key Features

• Cobalt construction for superior heat and wear resistance over standard HSS bits
• 49/64 inch cutting diameter in a stub-length screw machine profile for added rigidity
• 1/2 inch reduced shank fits standard drill chucks and machine spindles
• USA manufactured to consistent dimensional tolerances
• Minimum order quantity of 1 — available as a single unit

Compatibility

Designed as a direct-fit replacement or shop stock drill bit for any 1/2-inch chuck drill press, CNC machine, or handheld drill motor accepting a 1/2-inch shank; no specific compatible model numbers were stated in the product data.

Installation Notes

Secure the shank fully in the chuck and verify runout before drilling. Always wear appropriate eye and face protection when operating drill equipment on metal stock. Follow applicable OSHA and shop safety standards for rotating cutting tools. Use cutting fluid or coolant appropriate for the base material to extend tool life when drilling hard alloys or stainless steel.
