Built to Series 501-6 specifications, it features a 135-degree split point that is self-centering and eliminates the need for a center punch on most materials. The 0.209 inch diameter matches Wire Size 4 and is ground with a straight cylindrical shank of the same diameter for positive chuck grip. The oxide finish provides light corrosion resistance during storage and use. Licensed tradespeople and aerospace MRO technicians use this bit for drilling through structural members, bulkheads, and assemblies requiring extended reach.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for general-purpose drilling in ferrous and non-ferrous metals, plastics, and composite materials where a 4xD flute-length-to-diameter ratio is required for chip clearance at depth. The 2.5 inch flute length and 6 inch overall length make it a practical choice for aircraft maintenance, HVAC sheet metal work, and structural steel fabrication where access is limited. Right-hand cutting direction is standard for conventional drill presses, hand drills, and drill motors.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point is self-centering and reduces walking on hard surfaces\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web improves chip evacuation and reduces thrust force\u003c\/li\u003e\n  \u003cli\u003e0.209 inch diameter ground to Wire Size 4 for precise fitment\u003c\/li\u003e\n  \u003cli\u003e6 inch overall length with 2.5 inch flute length for extended-reach drilling\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles general-purpose metal drilling\u003c\/li\u003e\n  \u003cli\u003eOxide finish provides light surface protection\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type B standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style aircraft extension drill bit conforming to NAS 907 Type B.

Secure the shank firmly in the drill chuck before use and verify the workpiece is clamped or fixtured to prevent movement. Use appropriate cutting fluid for ferrous metals to extend bit life and improve hole quality. Inspect the cutting edges and split point for wear or chipping before each use and replace the bit if damage is observed.\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: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.209 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: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.209 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\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\u003eSelf-Centering\u003c\/strong\u003e: Yes\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\u003eWeight\u003c\/strong\u003e: 0.04 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: 6001443\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51692527780146,"sku":"6001443","price":16.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/242a725ff91a89d972c5cf595935e053_75a10c98-d624-4674-bf75-f0a17da6b923.jpg?v=1788298936","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6001443-aircraft-extension-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
