The EAGLE CUTTING TOOL A712-010-I is a high-speed steel (HSS) aircraft extension drill bit designed for drilling in tight or deep-reach applications where standard-length bits fall short. With a 5/32 inch diameter and a 12 inch overall length (OAL), this bit provides the extended reach required for airframe, automotive, and structural drilling tasks. HSS construction delivers durability across a range of ferrous and non-ferrous materials. It is well suited for HVAC technicians, sheet metal workers, mechanics, and maintenance professionals who need reliable depth penetration without multiple bit setups.
This drill bit is intended for use in applications where deep or extended-reach drilling is required, including drilling through structural panels, ductwork, sheet metal, and similar materials. The 12 inch OAL makes it a practical choice when working in confined spaces or accessing recessed mounting locations that standard drill bits cannot reach. It is compatible with standard 3-jaw drill chucks found on corded and cordless drills as well as drill presses.
Designed as a standard aircraft-length extension drill bit for use with 3-jaw drill chucks on handheld drills, right-angle drills, and drill presses where a 5/32 inch diameter and 12 inch OAL are required.
Insert and secure the bit fully into the drill chuck before operation to prevent slippage under torque. Ensure the workpiece is clamped or otherwise secured prior to drilling. Use appropriate cutting fluid or lubricant when drilling through harder metals to extend bit life. Always wear appropriate eye and hand protection in accordance with applicable workplace safety standards.
