The EAGLE CUTTING TOOL A700-011-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 workpoint. With an 11/64-inch diameter and a 6-inch overall length (OAL), this bit delivers the reach needed for aircraft-style drilling tasks encountered in HVAC, sheet metal, electrical, and mechanical trade work. The HSS construction handles a wide range of materials including mild steel, aluminum, and plastics. It is sized for use in standard drill chucks and is appropriate for both handheld and drill-press setups.
Aircraft extension drill bits like the A700-011-I are commonly used by HVAC installers, electricians, plumbers, and sheet metal workers when drilling through wall cavities, structural members, or stacked panels where extra reach is required. The 11/64-inch diameter is a common pilot and clearance size for fastener and conduit work. This import-grade bit suits high-volume or production environments where cost-per-hole is a factor.
Designed as a standard HSS aircraft-style extension drill bit compatible with any drill chuck accepting a standard round shank in the 11/64-inch diameter range.
Aircraft extension drill bits are typically used by HVAC technicians, electricians, and sheet metal workers. Always secure the workpiece before drilling and use appropriate cutting fluid when drilling mild steel to extend bit life. Ensure the drill chuck is tightened fully before operation to prevent bit slippage. Wear appropriate eye protection in accordance with job-site safety requirements.
