Eagle Cutting Tool C1080-042-D Cobalt Drill Bit 21/32 in

Product Description

The EAGLE CUTTING TOOL C1080-042-D is a cobalt screw machine (stub length) drill bit with a 21/32 inch cutting diameter and a 1/2 inch reduced shank. Cobalt high-speed steel construction provides elevated heat resistance and edge retention compared to standard HSS, making this bit suited for drilling hard and abrasive materials including stainless steel, cast iron, titanium, and hardened alloys. The stub-length body increases rigidity and reduces deflection in short-hole drilling applications. Manufactured in the USA.

This drill bit is used in metal fabrication shops, mechanical contracting, and maintenance environments where hard-material drilling is routine. The 1/2 inch shank fits standard 1/2 inch drill chucks and milling machine spindles. Stub length geometry is preferred when working in tight clearances or when maximizing drill rigidity is a priority over reach. Suitable for use in drill presses, milling machines, and heavy-duty hand drills with compatible chucks.

Key Features

• Cobalt high-speed steel construction for heat and wear resistance in hard-material applications
• 21/32 inch cutting diameter with a 1/2 inch reduced shank for use in standard chucks
• Stub screw machine length for increased rigidity and reduced deflection
• Made in the USA

Compatibility

Designed as a direct-fit replacement or upgrade cobalt drill bit for any 1/2 inch keyed or keyless chuck rated for a 21/32 inch cutting diameter in drill press or milling machine applications.

Installation Notes

Installation and use should be performed by machinists, tool-and-die professionals, or qualified maintenance technicians familiar with metal cutting practices. Secure the shank fully in the chuck before operation and verify the chuck is tightened with a chuck key where applicable. Always wear appropriate eye protection and follow facility lockout/tagout procedures when mounting tooling in powered equipment. Do not exceed the recommended feed rate or spindle speed for the material being drilled.
