The EAGLE CUTTING TOOL A712-014-I is a high-speed steel (HSS) aircraft extension drill bit designed for drilling in tight or deep-reach applications where a standard-length bit cannot access the work area. With a diameter of 7/32 inches and an overall length (OAL) of 12 inches, this bit provides the extended reach needed for structural, sheet metal, and aerospace-style drilling tasks. Licensed HVAC techs, sheet metal fabricators, plumbers, and general tradespeople keep extended-length bits like this in rotation for drilling through framing, ductwork flanges, and structural members where angle or depth makes standard bits impractical.
This aircraft drill bit is suited for use in residential and light commercial construction, mechanical trades, and fabrication environments. The extended 12-inch OAL makes it particularly useful when drilling through wall assemblies, floor joists, or deep channel stock. It is compatible with standard drill chucks that accept a 7/32-inch shank. This is an import-grade bit intended for general trade use where production volume or cost per hole is a factor.
Designed as an extended-length replacement or supplemental drill bit for use in standard keyed or keyless drill chucks accepting a 7/32-inch shank diameter.
This bit is installed and operated by general tradespeople, sheet metal mechanics, and construction professionals using corded or cordless drills and drill presses. Ensure the chuck is fully tightened and the bit is running true before engaging the workpiece. Reduce feed pressure when drilling through hard materials to extend bit life and prevent breakage. Always wear appropriate eye protection when drilling.
