Built to Series 906 specifications and compliant with NAS 907 Type B standards, it features a 135-degree split point that is self-centering and eliminates the need for a center punch on most materials. The oxide finish provides mild corrosion resistance and reduces friction during drilling. With a diameter of 7\/64 inch (0.1094 inch decimal) and a 6-inch overall length, this bit delivers the reach needed for structural, sheet metal, and aerospace-style access work performed by machinists and trade professionals.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for through-drilling in confined or deep-set locations where extension length is required. Typical applications include aircraft and aviation maintenance, metal fabrication, HVAC ductwork, electrical panel work, and structural installations where a standard jobber-length bit cannot reach the target bore. The right-hand spiral flute and web-thinned, tapered web configuration promote efficient chip evacuation in ferrous and non-ferrous metals as well as plastics. It is a general-purpose tool appropriate for bench drill press, hand drill, and drill motor use across industrial and field settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point with self-centering geometry eliminates center-punch step on most substrates\u003c\/li\u003e\n\u003cli\u003e6-inch overall length provides extended reach into deep or obstructed bore locations\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction delivers durability across ferrous metals, non-ferrous metals, and plastics\u003c\/li\u003e\n\u003cli\u003eOxide finish reduces surface friction and provides mild corrosion resistance\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web reduces thrust load and improves cutting efficiency\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 Type B standard for consistent dimensional and performance compliance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-fit extension drill bit for use in any right-hand drill chuck accepting a straight cylindrical shank at 7\/64 inch diameter; confirm chuck capacity and application material before installation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists, maintenance technicians, and qualified trade professionals. Secure the bit fully into the chuck and verify concentricity before drilling. Always power down and lock out the drill motor before changing bits.
