Built to Series 502-6 specifications and finished with a black oxide coating, this bit features a 135-degree split point for self-centering starts without a center punch and a web-thinned, tapered web for reduced thrust and cleaner entry. At 6 inches overall length with a 3.4375-inch spiral flute, it provides the reach needed for structural, sheet metal, and airframe drilling work. Licensed tradespeople and aircraft maintenance technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for through-hole drilling in metal fabrication, aerospace maintenance, and general industrial applications where extended reach is required. The straight-cylindrical shank accepts standard drill chucks without adapters. The 4xD flute-length-to-diameter ratio and right-hand cutting direction make it appropriate for use in ferrous and non-ferrous metals in both handheld and drill-press setups. It meets NAS 907 Type B standards, making it a recognized choice for aircraft and structural drilling operations where dimensional compliance matters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point with self-centering geometry eliminates the need for a center punch on most surfaces\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web reduces cutting resistance and heat buildup during deep drilling\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length with 3.4375-inch flute provides extended reach for confined or deep-access locations\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish improves lubricity and corrosion resistance compared to bare HSS\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 0.332 inches fits standard keyless and keyed drill chucks directly\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type B standards for aircraft and structural drilling applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style general purpose extension drill bit compatible with standard drill chucks accepting a 0.332-inch straight-cylindrical shank, suitable for handheld drills, drill presses, and right-angle drill attachments used in metal drilling applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists, aircraft maintenance technicians, or skilled tradespeople familiar with metal drilling procedures. Power down all equipment and secure the workpiece before changing or seating the bit in the chuck. Ensure the shank is fully seated and the chuck is tightened before operation. Use appropriate cutting fluid or coolant for the material being drilled to extend bit life and maintain dimensional accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: Q\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.332 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: 3.4375 inches (3-7\/16 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, Self-Centering\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: 0.332 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 (Black Oxide)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 502-6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\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: 6001319\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51723236573490,"sku":"6001319","price":47.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0fc899d1bf6115334f340b397e07558e_f59daf70-5a0e-41a9-8fb1-0bed01f91711.jpg?v=1788602151","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6001319-letter-q-aircraft-extension-drill","provider":"Voomi Supply","version":"1.0","type":"link"}
