Built from high-speed steel with an oxide finish, it measures 6 inches in overall length with a 1.625-inch spiral flute. The 135-degree split point is self-centering and web-thinned, reducing walking and cutting effort on entry. This bit is manufactured to NAS 907 standards and suits general-purpose drilling tasks where a longer reach is required. It is commonly installed and used by aerospace technicians, maintenance mechanics, and machine shop professionals working with ferrous and non-ferrous metals.\u003c\/p\u003e\u003cp\u003eThis aircraft extension drill bit is intended for use where standard-length bits cannot reach, such as structural assemblies, aircraft airframes, and fabrication work requiring access through deep cavities or stacked materials. The straight cylindrical shank fits standard drill chucks without adapters. Its right-hand spiral flute geometry evacuates chips efficiently during through-hole and blind-hole drilling. General-purpose performance makes it suitable across a range of base metals encountered in production and MRO environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 30 wire gauge size  -  0.1285 inches decimal equivalent\u003c\/li\u003e\n\u003cli\u003e135-degree split point with self-centering geometry reduces drill walking\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web configuration lowers thrust requirements at entry\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with oxide finish for wear resistance\u003c\/li\u003e\n\u003cli\u003e6-inch overall length provides extended reach in confined or deep-access areas\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, 2-flute spiral design for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eManufactured to NAS 907 standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and general-use aircraft extension drill bit compatible with standard drill chucks accepting a 0.1285-inch straight cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is typically used by machinists, aerospace mechanics, and maintenance technicians. Ensure the drill chuck is fully tightened and the workpiece is secured before drilling. Apply appropriate cutting fluid when drilling ferrous metals to extend tool life and maintain dimensional accuracy. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 30\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.1285 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: 1.625 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: 0.1285 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: 0.2 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.E03.0326\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51779625746738,"sku":"C.E03.0326","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3b1e9262aaf305783a905cdf37ef84af.jpg?v=1789175068","url":"https:\/\/voomisupply.com\/products\/hertel-c-e03-0326-aircraft-extension-drill-bit-no-30","provider":"Voomi Supply","version":"1.0","type":"link"}
