Sized at Letter H (0.2660 inches decimal), this bit features a 135-degree split point that self-centers on contact, reducing walking and the need for a center punch. Constructed from high-speed steel with an oxide finish for added surface hardness, it spans 12 inches in overall length and uses a straight-cylindrical shank. The two-flute spiral configuration with a web-thinned, tapered web promotes efficient chip evacuation during extended-depth cuts.\u003c\/p\u003e\n\u003cp\u003eThis bit is built for general-purpose drilling in aerospace, aviation maintenance, and industrial fabrication environments where extended reach is required. It is well suited for drilling through airframe structures, tubing, and assemblies that restrict direct bit access. Right-hand cutting direction makes it compatible with standard drill presses, hand drills, and pneumatic drilling equipment. The 2.875-inch flute length provides adequate chip clearance even at depth. It meets NAS 907 standards, making it appropriate for work performed to aerospace drilling specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter H size — 0.2660 inches decimal equivalent\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with self-centering tip reduces layout and setup time\u003c\/li\u003e\n  \u003cli\u003e12-inch overall length for deep-reach and restricted-access drilling\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with oxide finish for surface durability\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web improves chip flow and reduces thrust force\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 aerospace drilling standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose aircraft extension drill bit compatible with standard straight-shank drill chucks accepting a 0.2660-inch shank diameter, suitable for use in hand drills, right-angle drills, and drill presses.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eAircraft extension drill bits should be installed by qualified aviation maintenance technicians or industrial machinists following applicable workplace and aerospace safety procedures. Ensure the drill chuck is fully secured around the straight-cylindrical shank before operation and confirm the workpiece is properly fixtured to prevent movement. Operate at speeds appropriate for the material being drilled — high-speed steel bits require reduced RPM on hard alloys to avoid overheating. Inspect the cutting edges and web for wear or damage before each use and replace the bit if tip geometry is compromised.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.2660 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: 2.875 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: 0.2660 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\u003eSelf-Centering\u003c\/strong\u003e: Yes\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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.E05.0676\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51736375951666,"sku":"C.E05.0676","price":44.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dc70c6259e279f4b62ef97e72a4011c4.jpg?v=1788777572","url":"https:\/\/voomisupply.com\/products\/hertel-c-e05-0676-aircraft-extension-drill-bit-letter-h","provider":"Voomi Supply","version":"1.0","type":"link"}
