Built to Series 501-6 specifications, this bit carries a wire gauge size of No. 36, equal to 0.1065 inches in decimal diameter. The 135-degree split point is self-centering and web-thinned, reducing the thrust force needed to start a cut without a center punch. The straight-cylindrical shank seats securely in standard drill chucks. The oxide finish provides light corrosion resistance during storage and handling. Licensed HVAC techs, machinists, and aircraft maintenance professionals rely on this geometry for consistent, repeatable holes in steel, aluminum, and similar materials.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for production and maintenance drilling in aerospace, HVAC sheet metal, and light fabrication environments. The extended overall length of 6 inches provides reach into recessed or deep-clearance locations where a jobber-length bit cannot access. The 1.4375-inch spiral flute length handles chip evacuation effectively in the materials targeted by NAS 907 Type B standards. Right-hand cutting direction is standard for conventional drill press and hand-drill operation. It is sold individually and is appropriate for single-hole or low-volume precision work where bit condition matters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge No. 36 cutting diameter — 0.1065 inches decimal equivalent\u003c\/li\u003e\n  \u003cli\u003e135-degree split point is self-centering and eliminates the need for a center punch\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web construction reduces feed force and improves chip flow\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length provides extended reach into confined or deep locations\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles steel, aluminum, and general-purpose materials\u003c\/li\u003e\n  \u003cli\u003eOxide finish offers basic corrosion protection for storage and field use\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type B standards for aircraft-grade drilling applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose aircraft extension drill bit conforming to NAS 907 Type B standards, compatible with standard drill chucks accepting a 0.1065-inch straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of this drill bit is performed by machinists, aircraft maintenance technicians, and sheet metal workers using conventional drill presses or hand-held power drills. Secure the straight-cylindrical shank firmly in the chuck before operation and verify chuck key removal prior to powering on. Use appropriate cutting fluid for ferrous materials to extend bit life and maintain hole tolerance. Inspect the split point for wear or chipping before each use, as a damaged point will compromise self-centering performance.\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. 36\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1065 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: 1.4375 inches (1-7\/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: 0.1065 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: 0.04167 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: 6001337\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51721080340786,"sku":"6001337","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/242a725ff91a89d972c5cf595935e053_173a67c0-e04f-45d9-855c-3b1843382340.jpg?v=1788573216","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6001337-aircraft-extension-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
