The EAGLE CUTTING TOOL A700-008-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 work area. With a 1/8-inch diameter and a 6-inch overall length (OAL), this bit provides the extended reach required for drilling through airframes, structural panels, sheet metal assemblies, and similar tight or recessed locations. It weighs 0.24 pounds. Machinists, aircraft maintenance technicians, and metalworking fabricators are the primary users of this type of tooling.
Aircraft extension drill bits like the A700-008-I are used wherever standard jobber-length bits fall short. Common applications include drilling through layered sheet metal, accessing fastener holes in structural assemblies, automotive body work, HVAC ductwork fabrication, and general metalworking tasks that require a longer reach. The 1/8-inch diameter suits pilot holes, rivet holes, and small-diameter through-holes in ferrous and non-ferrous metals.
Designed as an OEM-style replacement or direct-use aircraft extension drill bit suitable for use in standard 3-jaw drill chucks and right-angle drill attachments accepting 1/8-inch shanks.
Secure the bit fully in the chuck before drilling to prevent slippage and bit breakage. Use cutting fluid or lubricant when drilling ferrous metals to extend bit life and reduce heat buildup. Always wear appropriate eye protection when operating drilling equipment. Inspect the cutting edges before each use and replace if chipping or excessive wear is present.
