Eagle Cutting Tool AC712-032-I Cobalt Aircraft Drill

Product Description

The EAGLE CUTTING TOOL AC712-032-I is a cobalt aircraft extension drill designed for deep-reach drilling applications in aerospace, structural, and general metalworking work. With a 1/2 inch cutting diameter and a 12 inch overall length (OAL), this bit reaches into cavities and structural members where standard-length drills cannot. The cobalt construction provides elevated heat resistance and edge retention when drilling through hard metals including stainless steel, high-strength aluminum alloys, and titanium. Licensed machinists, aircraft maintenance technicians, and structural fabricators are the primary installers of this tool.

Aircraft extension drills like the AC712-032-I are specified when access depth exceeds the reach of jobber-length or stub drills. Common applications include airframe assembly and repair, drilling through stacked structural panels, and deep-hole work in fabrication shops. The extended shank allows the bit to pass through guide bushings and fixtures common in aerospace and structural drilling jigs. This is an import-grade bit suitable for production and maintenance environments where volume consumption is expected.

Key Features

• 1/2 inch cutting diameter for heavy material removal
• 12 inch overall length for extended reach into deep cavities and structural assemblies
• Cobalt construction for improved heat resistance and edge retention in hard metals
• Aircraft-style extension geometry for use with drill jigs and guide bushings
• Import-grade production bit suited for high-consumption maintenance and fabrication use

Compatibility

Designed as an OEM-style replacement aircraft extension drill for use in standard 1/2 inch chuck configurations on handheld and drill-press setups requiring extended reach.

Installation Notes

Installation is performed by machinists, aircraft maintenance technicians, or structural fabricators using a drill press, handheld power drill, or pneumatic drill motor with a 1/2 inch chuck. Secure the workpiece firmly before drilling and use appropriate cutting fluid when working through hard metals to extend bit life. Follow applicable shop safety procedures and relevant industry standards for drilling operations. Inspect the cutting edges before each use and replace the bit when edge chipping or excessive wear is observed.
