Built to Series 501-6 standards and conforming to NAS 907 Type B, it features a 135-degree split point that self-centers on contact, reducing the need for a center punch. The 0.228-inch diameter matches wire gauge size 1. The oxide finish provides basic corrosion resistance and helps reduce friction during cutting. This bit is suited for licensed maintenance technicians, aerospace fabricators, and precision metalworkers who require accurate, extended-reach holes in tight or deep workspaces.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for general-purpose drilling in metal, including aluminum, mild steel, and similar materials where extended reach is required. The 2.625-inch spiral flute length and 6-inch overall length make it well suited for drilling through structural members, frames, and assemblies where a standard-length bit cannot reach. Its right-hand cutting direction and two-flute spiral design promote efficient chip evacuation in through-hole and blind-hole operations alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point for self-centering starts without a pilot hole or center punch\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across general-purpose metal drilling\u003c\/li\u003e\n  \u003cli\u003eNAS 907 Type B compliant for aerospace and precision fabrication applications\u003c\/li\u003e\n  \u003cli\u003eOxide finish reduces surface friction and provides light corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web design reduces thrust and improves cutting efficiency\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length with 2.625-inch flute provides extended reach in deep or restricted access locations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-specification drill bit for use in standard straight-shank drill chucks accepting a 0.228-inch cylindrical shank, conforming to NAS 907 Type B aircraft extension drill specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed by machinists, aircraft maintenance technicians, and precision metalworkers using standard keyed or keyless drill chucks rated for the shank diameter. Secure the shank fully in the chuck before operation to prevent slippage under torque. Use appropriate cutting fluid for steel applications to manage heat buildup during extended drilling cycles. Always wear eye protection and secure workpieces firmly before drilling.\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: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.228 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: 2.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.228 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\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: 0.04167 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: 6001451\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51693351633202,"sku":"6001451","price":17.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/242a725ff91a89d972c5cf595935e053_b3036ff3-342d-4166-ab28-b6d1ca4dbba5.jpg?v=1788311095","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6001451-aircraft-extension-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
