It features a 135-degree split point that reduces walking and eliminates the need for a center punch on most materials. The spiral flute geometry and oxide finish help with chip evacuation and mild lubrication retention during cutting. With a 4-1\/16 inch flute length and 6 inch overall length, this bit delivers extended reach without sacrificing rigidity. It is suited for use by aviation maintenance technicians, metalworking tradespeople, and industrial maintenance mechanics.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is built for general-purpose metal drilling in applications requiring extended reach, such as drilling through structural airframe members, deep castings, machinery frames, and fabricated assemblies. The straight-cylindrical shank accommodates standard drill chucks. The Series 500-6 designation indicates this bit conforms to extended-length aircraft drill standards, making it appropriate for MRO shops, aerospace fabrication, and industrial maintenance environments where access is restricted and hole location accuracy is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point for self-centering entry and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across a range of ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e4-1\/16 inch flute length (4.0625 inches) provides extended reach for deep or obstructed holes\u003c\/li\u003e\n  \u003cli\u003eOxide finish aids in lubrication retention and mild corrosion resistance during storage and use\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces cutting resistance and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction, 2 spiral flutes, straight-cylindrical shank fits standard chucks\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type B standard for aircraft extension drills\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style aircraft extension drill bit suitable for use in standard drill chucks accepting a 7\/16 inch straight-cylindrical shank, conforming to NAS 907 Type B specifications for extended-length aircraft drilling applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists, aviation maintenance technicians, or industrial tradespeople familiar with metal drilling procedures. Secure the workpiece fully before drilling and ensure the drill chuck is tightened properly to prevent slippage. Use appropriate cutting fluid for the material being drilled to extend bit life and improve hole quality.
