Eagle Cutting Tool C1080-063-D Cobalt Drill Bit 63/64

Product Description

The EAGLE CUTTING TOOL C1080-063-D is a 63/64-inch cobalt screw machine (stub length) drill bit with a 1/2-inch reduced shank, manufactured in the USA. Cobalt high-speed steel construction gives this bit the heat resistance and hardness needed for drilling stainless steel, cast iron, hardened alloys, and other tough materials that standard HSS tooling struggles with. The stub-length flute geometry provides added rigidity and reduced deflection during drilling operations, making it a reliable choice for production environments and job-site metalworking alike. Licensed tradespeople and machining professionals working with heavy-gauge materials rely on this drill bit configuration for consistent hole quality.

This bit is suited for use in drill presses, CNC drilling centers, and heavy-duty hand-held drill units equipped to accept a 1/2-inch shank. The screw machine length design makes it especially practical for drilling operations where clearance is limited or where a shorter bit column improves control and accuracy. Typical applications include metalworking shops, fabrication facilities, mechanical contractors, and maintenance technicians working on industrial equipment.

Key Features

• Cobalt high-speed steel construction for superior heat and wear resistance in tough materials
• 63/64-inch cutting diameter for close-tolerance hole sizing
• 1/2-inch reduced shank fits standard drill chucks and collets
• Stub screw machine length provides increased rigidity and reduced deflection
• USA manufactured

Compatibility

Designed for use with drill presses, machining centers, and power drills accepting a 1/2-inch shank. Suitable as a direct replacement or working spare for cobalt screw machine drill bits of equivalent diameter and shank size.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with metal-cutting operations. Secure the shank fully in the chuck before operation and verify chuck key is removed prior to startup. Use appropriate cutting fluid when drilling hard metals to extend bit life and maintain hole quality. Inspect the cutting edges before each use and replace if chipping or excessive wear is observed.
