The EAGLE CUTTING TOOL A700-139-I is a Number 39 high-speed steel (HSS) aircraft-length drill bit with a 6-inch overall length (OAL). Designed for deep-reach drilling applications where a standard-length bit cannot access the worksite, this import-grade bit delivers the reach needed for structural and mechanical assembly work. HSS construction provides the hardness and wear resistance required for drilling through steel, aluminum, and similar metals encountered in trade and light industrial settings. The extended shank makes it well suited for drilling through thick stock, stacked material, or confined areas with limited tool clearance.
This aircraft-length drill bit is used in applications where standard jobber-length bits fall short. Common install scenarios include HVAC sheet metal fabrication, electrical panel and conduit work, plumbing rough-in through framing members, and general mechanical assembly. The Number 39 diameter is a common size for pilot holes, tap drilling, and precision hole sizing in metal. Trade professionals in HVAC, electrical, plumbing, and general construction will find this bit appropriate for both shop use and field work.
Designed as a standard aircraft-length drill bit compatible with any 3-jaw keyed or keyless chuck accepting round-shank bits of Number 39 diameter.
This bit is installed and used by HVAC technicians, electricians, plumbers, and general mechanical trades. Secure the bit firmly in the chuck before use and verify chuck key is removed prior to operating the drill. Use appropriate cutting fluid or lubricant when drilling hardened or thick steel stock to extend bit life and reduce heat buildup. Wear appropriate PPE including eye protection when operating any rotary cutting tool.
