Eagle Cutting Tool AC700-016-I Cobalt Aircraft Drill

Product Description

The EAGLE CUTTING TOOL AC700-016-I is a cobalt aircraft drill designed for deep-reach drilling applications in aerospace, aviation maintenance, and industrial fabrication. With a 1/4 inch diameter and a 6 inch overall length (OAL), this bit reaches into deep bores and confined spaces where standard-length drills cannot. The cobalt construction provides increased heat and wear resistance compared to standard high-speed steel, making it suitable for drilling through tough alloys, stainless steel, and hardened materials common in aircraft and structural work. Licensed technicians, A&P mechanics, and fabricators keep extended-length cobalt drills like this on hand for through-hole and blind-hole work in thick or stacked material.

This drill is intended for extended-reach applications in sheet metal, aluminum, stainless steel, and other hard materials encountered in aircraft repair, aerospace assembly, and general industrial fabrication. The 6 inch OAL makes it practical for drilling through thick structural members or accessing deep cavities that standard jobber-length drills cannot reach. It is suited for use in handheld drill motors, drill presses, and magnetic base drills commonly used in aviation and industrial maintenance environments.

Key Features

• 1/4 inch diameter with 6 inch overall length for deep-reach drilling
• Cobalt construction for enhanced heat resistance and extended tool life in hard materials
• Aircraft-length geometry designed for use in confined and deep-bore applications
• Suitable for drilling stainless steel, aluminum, hard alloys, and stacked materials
• Minimum order quantity of 1 unit

Compatibility

Designed as an extended-length cobalt aircraft drill for use in standard 1/4 inch drill chucks found on handheld drill motors, drill presses, and magnetic base drills used in aerospace, aviation maintenance, and industrial fabrication applications.

Installation Notes

This drill bit is installed by qualified machinists, A&P mechanics, or industrial fabricators using appropriate drill motor equipment. Secure the shank fully in the chuck before operation and verify the workpiece is firmly clamped to prevent movement. Use appropriate cutting fluid or lubricant when drilling hard alloys or stainless steel to extend tool life and improve hole quality. Follow applicable shop safety standards and wear appropriate eye protection during use.
