The 17\/64 inch (0.2656 inch decimal) diameter bit features a 135-degree split point that is self-centering and reduces the need for a center punch on most metals. With a flute length of 2.875 inches and an overall length of 12 inches, this Series 500-12 bit reaches into cavities and structural members that standard-length drill bits cannot access. Licensed trades and aerospace maintenance technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for drilling through aluminum sheet, mild steel, and other metals encountered in aircraft maintenance, HVAC equipment fabrication, structural steel work, and general industrial applications. The extended 12-inch overall length is the defining application feature, allowing access to confined or deep locations. The oxide finish provides moderate corrosion resistance and helps retain cutting fluid during use. Right-hand cutting direction is standard for use with conventional drill motors and drill presses.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point is self-centering, reducing walk on hard or curved surfaces\u003c\/li\u003e\n  \u003cli\u003e12-inch overall length provides extended reach into deep or confined workpieces\u003c\/li\u003e\n  \u003cli\u003e2.875-inch spiral flute length with 4xD flute-to-diameter ratio for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction suitable for ferrous and non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard 3-jaw chucks without an adapter\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces thrust force and extends cutting life\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type B standard for aircraft extension drill bits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and general-use aircraft extension drill bit for applications requiring a 17\/64 inch diameter, 12-inch overall length, straight-shank drill conforming to NAS 907 Type B specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed by machinists, sheet metal workers, and maintenance technicians using a standard drill motor or drill press equipped with a 3-jaw chuck. Secure the straight-cylindrical shank fully in the chuck before use to prevent slippage under load. Use appropriate cutting fluid for the workpiece material to extend bit life and improve hole finish. Ensure the workpiece is properly clamped before drilling to prevent rotation or shifting during the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 17\/64 inch (0.2656 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 17\/64 inch (0.2656 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split, Self-Centering\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 500-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: NAS 907 Type B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.083 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6001347\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51699224281394,"sku":"6001347","price":37.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/00c62afe4afb4c768fcc83692ac48d80_c85c31c9-54f3-4f40-b53c-26ef20c0411a.jpg?v=1788373761","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6001347-aircraft-extension-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
