Eagle Cutting Tool AC712-008-I Cobalt Aircraft Drill

Product Description

The EAGLE CUTTING TOOL AC712-008-I is a cobalt aircraft extension drill designed for deep-reach drilling in aerospace, structural, and sheet metal applications. Built with a 1/8 inch diameter and a 12 inch overall length (OAL), this drill bit provides the extended reach required when standard-length bits cannot access the work area. Cobalt construction delivers heat resistance and edge retention when drilling through tough materials such as stainless steel, hardened steel, and high-strength aluminum. Licensed tradespeople and maintenance technicians rely on this geometry for clean, accurate holes in tight or deep cavities.

This drill is suited for aircraft maintenance, structural steel fabrication, HVAC ductwork, and general metalworking where extended reach is a requirement. The 12 inch OAL makes it practical for drilling through thick assemblies, framing members, or stacked sheet metal panels where a jobber-length bit would fall short. It is also commonly used by electricians and pipefitters when routing through deep structural members.

Key Features

• 1/8 inch diameter with 12 inch overall length for extended-reach drilling
• Cobalt construction for superior heat resistance and extended tool life in hard metals
• Aircraft-style geometry provides accurate entry and reduced walking on metal surfaces
• Minimum order quantity of 1 — available as a single unit
• Lightweight at 0.24 pounds for reduced fatigue during overhead or awkward-angle drilling

Compatibility

Designed as a standard shank extension drill compatible with conventional drill chucks accepting 1/8 inch round shanks, suitable for handheld drills, drill presses, and right-angle drill attachments used in metalworking and maintenance applications.

Installation Notes

This drill is installed and used by machinists, sheet metal workers, aircraft mechanics, electricians, and pipefitters working with standard drill equipment. Secure the shank fully in the chuck and confirm chuck tightness before operation. Use appropriate cutting fluid or lubricant when drilling ferrous metals to preserve edge life and reduce heat buildup. Always wear eye protection and secure the workpiece before drilling.
