Built to Series 501-6 standards and conforming to NAS 907 Type B, this bit features a 135-degree split point that is self-centering and eliminates the need for a center punch on most materials. The straight cylindrical shank measures 0.1695 inches in diameter, matching the cutting diameter for consistent chuck engagement. An oxide finish provides baseline corrosion resistance and reduces friction during drilling. The two-flute spiral design with a web-thinned, tapered web configuration promotes efficient chip evacuation and reduces feed force.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for professionals performing aircraft structural work, sheet metal fabrication, and general-purpose precision drilling where extended reach is required. The 6-inch overall length gives technicians access to recessed or deep locations that standard-length bits cannot reach. The right-hand cutting direction and 4xD flute-to-diameter ratio make it a practical fit for hand drilling with a standard electric drill or drill press in production and maintenance environments. Aviation maintenance technicians, machinists, and sheet metal workers are the primary users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point is self-centering for accurate hole starts without a center punch\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles a wide range of metals including aluminum, mild steel, and soft alloys\u003c\/li\u003e\n  \u003cli\u003eExtended 6-inch overall length provides reach into confined or deep locations\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces cutting resistance and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eOxide finish reduces surface friction and provides light corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eConforms to NAS 907 Type B standard for aircraft-grade dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style aircraft extension drill bit conforming to NAS 907 Type B, suitable for use with standard 3-jaw chucks and drill presses that accept a 0.1695-inch straight cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, aviation maintenance technicians, and sheet metal workers using a drill press or hand drill with an appropriate chuck. Secure the workpiece firmly before drilling and confirm the chuck is tightened to the shank before operating. Always wear appropriate eye protection and follow applicable shop safety protocols when drilling metal. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1695 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.125 inches\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSelf-Centering\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length to Diameter Ratio\u003c\/strong\u003e: 4xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1695 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: 501-6\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: 0.04167 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: 6001471\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51693721616690,"sku":"6001471","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/242a725ff91a89d972c5cf595935e053_7f169503-055d-4f97-ac68-f56f2849b7cc.jpg?v=1788316546","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6001471-aircraft-extension-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
