The 135-degree split point geometry is self-centering, reducing the need for a center punch and minimizing walking on entry. A spiral flute with web thinning and a tapered web configuration improves chip evacuation and reduces thrust. The oxide finish provides mild corrosion resistance and helps retain cutting fluid. At 0.166 inches in diameter and 6 inches overall length, this bit is suited for applications where standard-length drills cannot reach.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is used in aerospace fabrication, aircraft maintenance and repair, and general metalworking where extended reach is required. The Series 501-6 designation identifies it as a general-purpose aircraft extension drill conforming to NAS 907 Type B standards. It is appropriate for use in tight bays, structural panels, and assemblies where a standard jobber-length bit lacks the clearance or reach to complete the hole. Right-hand cutting direction is standard for conventional drill press and hand-drill operation. Typical installers include aviation maintenance technicians, sheet metal fabricators, and general machine shop operators.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point with self-centering geometry eliminates pilot hole requirement on most metals\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces drilling thrust and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction suitable for steel, aluminum, and composite drilling\u003c\/li\u003e\n  \u003cli\u003eOxide finish for mild corrosion resistance and lubricity retention\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length with 2.125-inch flute length provides extended reach in confined assemblies\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type B standard for aircraft-grade drill bits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use aircraft extension drill conforming to NAS 907 Type B, suitable for use with standard 0.166-inch straight-cylindrical shank drill chucks in hand drills, drill presses, and right-angle drill adapters.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis drill bit is installed by aviation maintenance technicians and metalworking professionals following applicable maintenance manuals and shop procedures. Secure the workpiece before drilling and ensure the drill chuck is tightened fully to prevent shank slippage. Use appropriate cutting fluid when drilling steel or hard alloys to extend tool life and improve hole quality. Inspect the split point for chipping or wear before each use and discard the bit if the cutting edges are damaged.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 19\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1660 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1660 inches\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\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\u003eWeight\u003c\/strong\u003e: 0.042 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: 6001473\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51694106804530,"sku":"6001473","price":15.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/242a725ff91a89d972c5cf595935e053_4bc910b3-7059-483e-82c7-15a34c770460.jpg?v=1788320323","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6001473-no-19-hss-aircraft-drill","provider":"Voomi Supply","version":"1.0","type":"link"}
