The EAGLE CUTTING TOOL A712-015-I is a high-speed steel (HSS) aircraft extension drill bit engineered for deep-reach drilling applications in metal fabrication and aerospace maintenance work. With a 15/64 inch diameter and a 12 inch overall length (OAL), this bit is built for reaching fastener locations, structural members, and rivet holes that standard-length drills cannot access. HSS construction provides the hardness and heat resistance required for drilling through aluminum, mild steel, and other common airframe and structural materials. Licensed tradespeople and experienced technicians are the primary users of this type of tooling.
Aircraft extension drills are commonly used in aviation maintenance, sheet metal fabrication, HVAC ductwork installation, and structural assembly work where drilling through confined or deep cavities is required. The 12 inch OAL makes this bit well suited for applications where panel depth or framing obstruction prevents use of a standard jobber-length drill. It fits any drill chuck sized to accept a 15/64 inch shank.
Designed as an OEM-style aircraft extension drill for use in standard drill chucks and right-angle drill attachments that accept a 15/64 inch diameter bit.
Aircraft extension drills are typically used by aviation maintenance technicians, sheet metal workers, and structural fabricators. Secure the workpiece before drilling and use appropriate cutting fluid when drilling through steel to reduce heat buildup and extend bit life. Always wear appropriate eye protection. Inspect the bit for cracks or deformation before each use and replace if any damage is found.
