Built to Series 501-6 specifications, it carries a wire size of 38 (0.1015 inches decimal), a 135-degree split point for self-centering entry, and an oxide finish that provides mild lubricity and corrosion resistance. The 1.4375-inch spiral flute length and straight-cylindrical shank make it well-suited for controlled, accurate drilling where standard-length bits cannot reach. Licensed HVAC technicians, aircraft maintenance professionals, and sheet metal workers routinely specify this drill for close-tolerance applications.\u003c\/p\u003e\n\u003cp\u003eThis bit is designed for general-purpose drilling in metal substrates including steel, aluminum, and similar materials. The aircraft extension design provides additional reach beyond a standard jobber-length drill, making it useful in deep-cavity installations, structural repairs, and confined-space fastener hole preparation. The right-hand cutting direction and two-flute spiral geometry ensure consistent chip evacuation during use. Its NAS 907 Type B compliance makes it a recognized choice for aerospace and defense maintenance tasks where standardized tooling is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point for self-centering drilling without a center punch\u003c\/li\u003e\n  \u003cli\u003eWire size 38 (0.1015 inches) straight-cylindrical shank for standard chuck compatibility\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles a broad range of metal substrates\u003c\/li\u003e\n  \u003cli\u003eOxide finish provides mild lubrication and resistance to corrosion\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces cutting resistance and heat buildup\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type B standard for aerospace and industrial applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or general-use drill bit compatible with standard 3-jaw drill chucks accepting a 0.1015-inch straight-cylindrical shank, suitable for benchtop drill presses, hand drills, and magnetic base drills used in metal fabrication and aircraft maintenance.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of this drill bit should be performed by a qualified machinist, aircraft mechanic, or sheet metal technician familiar with cutting speed and feed rate selection for the target material. Secure the shank fully in the chuck and verify concentricity before drilling. Always use appropriate cutting fluid when drilling steel to extend bit life and reduce heat. Follow applicable shop safety standards and wear proper eye protection during all drilling operations.\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: 38\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.1015 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 Point\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1015 inches\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\u003eSelf-Centering\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered Web-Thinned\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: 6001427\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51717468291378,"sku":"6001427","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/242a725ff91a89d972c5cf595935e053_e73ebb00-dfc1-4a87-93f7-d0fdd6b4db05.jpg?v=1788540981","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6001427-aircraft-extension-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
