Eagle Cutting Tool C1080-062-D Cobalt Drill Bit 31/32 in

Product Description

The EAGLE CUTTING TOOL C1080-062-D is a 31/32-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 increased heat and wear resistance compared to standard HSS bits, making it suitable for drilling harder materials including stainless steel, cast iron, and high-nickel alloys. The stub-length body offers greater rigidity and reduced deflection in short-hole drilling operations. This bit is intended for use by machinists, pipefitters, ironworkers, and industrial maintenance technicians working with drill presses, CNC machines, or magnetic drills.

This drill bit is well suited for production drilling environments where heat buildup and bit wear are concerns. The reduced 1/2-inch shank allows it to seat in standard 1/2-inch chucks without requiring a larger spindle capacity. Typical applications include drilling through structural steel, heavy plate, pipe flanges, and other ferrous metals in industrial, fabrication, and maintenance settings. The screw machine length keeps the cutting edge close to the chuck for improved stability on demanding cuts.

Key Features

• Cobalt high-speed steel construction for extended tool life in hard and abrasive materials
• 31/32-inch cutting diameter in a stub screw machine length for added rigidity
• 1/2-inch reduced shank fits standard 1/2-inch drill chucks
• Made in the USA
• Minimum order quantity of 1 — available as a single unit

Compatibility

Designed as an OEM-style replacement or standard tooling addition for 1/2-inch chuck drill presses, magnetic drills, and CNC drilling spindles requiring a 31/32-inch cobalt screw machine drill bit.

Installation Notes

This bit is installed and operated by machinists, ironworkers, or qualified maintenance technicians. Ensure the drill press or machine spindle is fully powered down and locked out before changing tooling. Seat the 1/2-inch shank fully and securely in the chuck before operation. Use appropriate cutting fluid or coolant when drilling hard ferrous materials to maximize bit life and maintain dimensional accuracy.
