The EAGLE CUTTING TOOL A700-030-I is a high-speed steel (HSS) aircraft extension drill bit designed for deep-reach drilling applications where a standard-length bit cannot access the workpoint. With a 15/32 inch diameter and a 6 inch overall length (OAL), this bit provides the extended reach required for drilling through airframe structures, deep cavities, and layered assemblies. HSS construction delivers the hardness and heat resistance needed for sustained use in ferrous metals, aluminum, and composite materials. Machinists, aviation maintenance technicians, and sheet metal workers typically reach for this bit when clearance depth is the limiting factor on the job.
This aircraft drill is suited for use in aerospace maintenance, automotive bodywork, HVAC ductwork fabrication, and general metal fabrication where standard-length bits fall short. The 15/32 inch diameter makes it appropriate for pilot holes, clearance holes, and through-holes in metal framing and structural assemblies. Its extended OAL allows drilling through stacked material thicknesses or through structural members that would otherwise require an extended reach adapter.
Designed as a general-purpose extended-length HSS drill bit compatible with standard drill chucks and pneumatic drill motors that accept 15/32 inch shank sizes, typical in aviation maintenance and metal fabrication applications.
This bit is installed by a machinist, aviation maintenance technician, or sheet metal worker using a corded drill, pneumatic drill motor, or drill press with a compatible chuck. Ensure the workpiece is properly secured before drilling and apply cutting fluid when drilling ferrous metals to extend bit life and reduce heat. Inspect the cutting edges before each use and replace the bit if chipping or dullness is observed. Follow applicable workplace safety standards for rotating tool operation.
