Built from high-speed steel with an oxide finish, this bit is engineered for extended reach drilling in aerospace and general industrial applications. At 12 inches overall length with a 3.3125-inch spiral flute, it provides access to deep or recessed hole locations that standard-length bits cannot reach. The self-centering split point reduces walking on entry, and right-hand cutting with two flutes ensures efficient chip evacuation. Meets NAS 907 standards.\u003c\/p\u003e\u003cp\u003eThis bit is suited for use in aerospace fabrication, MRO (maintenance, repair, and overhaul) environments, and industrial production where deep-reach drilling in metal is required. The straight cylindrical shank accepts standard drill chucks. General-purpose tool performance makes it appropriate for drilling aluminum, mild steel, and similar structural metals common in aircraft and industrial assemblies. Machinists, aerospace mechanics, and metal fabricators are the primary installers of this tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter P size — 0.3230 inches decimal equivalent\u003c\/li\u003e\n\u003cli\u003e135-degree split point with self-centering geometry for accurate entry\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web for reduced thrust and improved chip flow\u003c\/li\u003e\n\u003cli\u003e12-inch overall length for extended reach into deep or obstructed locations\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with oxide finish for wear resistance\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 standard for aircraft extension drill bits\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with 2-flute design for efficient swarf removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose aircraft extension drill bit compatible with any standard drill chuck accepting a 0.3230-inch straight cylindrical shank, suitable for aerospace and industrial metal drilling applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed and operated by machinists, aerospace mechanics, or metal fabricators using standard or extended-reach drill presses, hand drills, or right-angle drill units. Secure the straight shank firmly in the chuck before operation and verify chuck capacity accommodates a 0.3230-inch shank. Use appropriate cutting fluid for the workpiece material to extend bit life and maintain hole quality. Inspect the cutting edges for wear or damage before each use and replace the bit if chipping or dullness is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.3230 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.3125 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\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: 0.3230 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\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\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: NAS 907\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C.E05.0820\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51736734761266,"sku":"C.E05.0820","price":53.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5921217d0e249d4e46ee6831d3c5be2a.jpg?v=1788779611","url":"https:\/\/voomisupply.com\/products\/hertel-c-e05-0820-aircraft-extension-drill-bit-letter-p","provider":"Voomi Supply","version":"1.0","type":"link"}
