Eagle Cutting Tool C1080-058-D Cobalt Drill Bit 29/32 in

Product Description

The EAGLE CUTTING TOOL C1080-058-D is a 29/32-inch cobalt short-length (screw machine) drill bit with a 1/2-inch reduced shank, manufactured in the USA. Cobalt construction provides increased heat resistance and durability compared to standard high-speed steel, making it well suited for drilling hard and abrasive materials. The short flute length of a screw machine style bit delivers added rigidity and improved hole accuracy in production and maintenance drilling applications. At 0.69 pounds, it is a solid, tool-quality bit built for professional use in metalworking and fabrication environments.

This drill bit is intended for use in metalworking, machining, and industrial maintenance settings. The screw machine (SD) geometry, combined with a 1/2-inch shank, allows it to seat securely in standard 1/2-inch drill chucks and machine spindles. It is a practical choice for machinists, maintenance technicians, pipefitters, and fabricators who regularly drill through steel, stainless, cast iron, or other tough alloys where heat buildup and bit wear are common concerns.

Key Features

• 29/32-inch diameter cobalt construction for drilling hard and abrasive metals
• Short screw machine (SD) flute length provides rigidity and reduces deflection
• 1/2-inch reduced shank fits standard drill chucks and machine spindles
• Cobalt alloy offers superior heat and wear resistance over standard HSS
• Made in the USA

Compatibility

Designed as an OEM-style replacement or direct-use cobalt screw machine drill bit for 1/2-inch chuck drill presses, milling machines, and hand drills used in metalworking and industrial maintenance applications.

Installation Notes

This bit should be installed and secured in a properly rated 1/2-inch chuck before operation. Always verify the chuck is fully tightened and the workpiece is clamped securely before drilling. Use appropriate cutting fluid when drilling hardened or stainless steel to extend bit life and manage heat. Wear appropriate PPE, including safety glasses and gloves, when operating cutting tools.
