Eagle Cutting Tool AC712-012-I Cobalt Aircraft Drill

Product Description

The EAGLE CUTTING TOOL AC712-012-I is a cobalt aircraft drill bit designed for extended-reach drilling applications in aerospace, automotive, and structural metalworking. The cobalt construction provides heat resistance and edge retention when drilling through hard materials such as stainless steel, high-strength alloys, and hardened metals. At 3/16 inch in diameter and 12 inches in length, this bit is built for reaching deep or obstructed bore locations that standard-length drill bits cannot access. It is a standard import-grade cobalt bit suited for use by machinists, sheet metal workers, and maintenance technicians requiring extra-length capability.

This drill bit is used in applications where standard jobber-length drills fall short. Typical scenarios include drilling through aircraft skin and structural frames, automotive unibody and frame work, and industrial maintenance tasks involving deep or offset hole placement. The 3/16 inch diameter makes it suitable for pilot holes, riveted joint drilling, and bolt-clearance work in metal fabrication environments. Import-grade construction keeps acquisition costs in line for high-turnover shop use.

Key Features

• Cobalt steel construction for heat resistance and extended tool life in hard-metal drilling
• Extra-long 12-inch length provides extended reach for deep or obstructed bore locations
• 3/16 inch diameter suits pilot holes, rivet drilling, and bolt-clearance applications
• Import-grade pricing supports high-consumption shop and field use
• Designed for use in aerospace, automotive, and structural metalworking applications

Compatibility

Designed as a standard 3/16 inch shank cobalt aircraft-length drill bit compatible with any drill motor, drill press, or magnetic base drill accepting a 3/16 inch round shank.

Installation Notes

Installation of this drill bit is performed by machinists, sheet metal workers, and maintenance technicians using standard drill motors or drill presses. Secure the shank fully in the chuck before drilling and verify the workpiece is clamped to prevent movement. Use appropriate cutting fluid when drilling hardened or stainless steel to extend bit life and maintain hole quality. Dispose of worn bits per shop safety procedures and inspect the cutting edges before each use.
