Eagle Cutting Tool C1080-060-D Cobalt Drill Bit 15/16 in

Product Description

The EAGLE CUTTING TOOL C1080-060-D is a cobalt screw machine length (stub) drill bit designed for high-performance drilling in tough materials. Built to a 15/16 inch diameter with a 1/2 inch straight shank, this bit is suited for use in drill presses, milling machines, and heavy-duty handheld equipment. The cobalt construction provides increased heat resistance and hardness over standard high-speed steel, making it a go-to choice for machinists, maintenance technicians, and fabricators working with stainless steel, cast iron, and other hard or abrasive materials. Manufactured in the USA.

The C1080-060-D is intended for production and maintenance drilling applications where a shorter flute length offers greater rigidity and reduced deflection. Screw machine length bits are commonly used in CNC machining centers, turret lathes, and production drill presses. The 1/2 inch shank accommodates standard drill chucks and collet systems across a wide range of machine tool setups. This bit is appropriate for metal fabrication shops, industrial maintenance environments, and toolroom work.

Key Features

• 15/16 inch diameter for larger bore applications
• Cobalt alloy construction resists heat and wear during high-speed drilling
• Screw machine length provides added rigidity and reduced chatter
• 1/2 inch straight shank fits standard drill chucks and collets
• Made in the USA

Compatibility

Designed as an OEM-style replacement or direct-use drill bit compatible with any drill press, milling machine, or power tool equipped with a 1/2 inch or larger chuck or collet system.

Installation Notes

Installation and use should be performed by qualified machinists or trained tradespeople familiar with machine tool operation. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable tolerance. Always use appropriate cutting fluid when drilling hard metals to extend tool life and maintain hole quality. Follow applicable shop safety procedures and machine manufacturer guidelines during setup and use.
