Eagle Cutting Tool A712-017-I Hss Aircraft Drill 17/64

Product Description

The EAGLE CUTTING TOOL A712-017-I is a high-speed steel (HSS) aircraft extension drill bit engineered for deep-reach drilling applications in aerospace, aviation maintenance, and general metalworking. With a 17/64 inch diameter and a 12 inch overall length (OAL), this bit provides the extended reach needed to access tight or deep bore locations that standard-length drills cannot serve. The HSS construction delivers reliable cutting performance across steel, aluminum, and other common structural metals. This type of drill is a standard tool for airframe technicians, sheet metal workers, and maintenance mechanics working on aircraft structures and similar assemblies.

Aircraft extension drills are used wherever standard drill lengths fall short. Common applications include drilling through airframe skins, structural panels, deep assemblies, and layered sheet metal stacks. The 12 inch OAL makes this bit well suited for reaching through bulkheads, framing members, or any workpiece where bit-to-chuck clearance is a limiting factor. It is appropriate for use in both hand-held pneumatic drills and drill press setups commonly found in MRO and fabrication environments.

Key Features

• 17/64 inch diameter for precise hole sizing in aircraft and sheet metal applications
• 12 inch overall length provides extended reach beyond standard drill bit lengths
• High-speed steel (HSS) construction maintains cutting edge integrity across ferrous and non-ferrous metals
• Compatible with standard drill chucks used in pneumatic and electric hand drills and drill presses
• Minimum order quantity of 1 for flexible purchasing

Compatibility

Designed as an OEM-style replacement and standard fitment aircraft extension drill for use in aerospace maintenance, aviation fabrication, and general metalworking applications requiring extended-reach HSS drill bits in the 17/64 inch diameter class.

Installation Notes

Aircraft extension drills should be installed by qualified airframe technicians, sheet metal workers, or experienced machinists familiar with proper drilling procedures. Secure the workpiece fully before drilling to prevent bit deflection, which is more pronounced with extended-length bits. Use appropriate cutting fluid or lubricant when drilling through steel or thick aluminum to preserve bit life. Follow applicable aviation maintenance manual (AMM) procedures and workplace safety requirements when performing structural drilling on aircraft.
