Built from high-speed steel with an oxide finish, it measures 12 inches in overall length and features a 2.1875-inch spiral flute. The 135-degree split point is self-centering and web-thinned, reducing the thrust required to start and maintain a cut through steel, aluminum, and similar materials. Two right-hand flutes clear chips efficiently during extended-reach operations. This bit is manufactured to NAS 907 standards, making it appropriate for precision trade work where dimensional accuracy matters.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for applications that require extended reach beyond what a standard-length bit can provide. Typical use cases include drilling through aircraft fuselage panels, structural steel, aluminum sheet, and deep-section assemblies where the work envelope does not allow a conventional bit to seat properly. The 0.1800-inch decimal diameter and straight cylindrical shank make it compatible with standard drill chucks and right-angle drill adapters common in aviation maintenance, fabrication shops, and mechanical contracting environments. General-purpose tool performance rating makes it appropriate for production and maintenance drilling alike.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 15 wire size, 0.1800-inch decimal diameter for precise hole sizing\u003c\/li\u003e\n\u003cli\u003e12-inch overall length provides extended reach into deep assemblies\u003c\/li\u003e\n\u003cli\u003e135-degree split point is self-centering, reducing walk-off on curved or angled surfaces\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web configuration lowers required drilling thrust\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with oxide finish for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eManufactured to NAS 907 standards for aerospace and precision trade applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style aircraft extension drill bit suitable for use with standard 3-jaw drill chucks and right-angle drill adapters accepting a 0.1800-inch straight cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of this bit is performed by machinists, aviation maintenance technicians, and metalworking tradespeople using standard drill presses, hand drills, or right-angle drills. Secure the straight cylindrical shank firmly in the chuck before use and verify the chuck is fully tightened to prevent slippage during extended-reach operations. Power down all equipment before changing bits. Do not exceed the recommended cutting speed for the work material, and use appropriate cutting fluid when drilling ferrous metals to extend bit life and maintain hole tolerance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1800 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: 2.1875 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\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1800 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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelf-Centering\u003c\/strong\u003e: Yes\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.E05.0457\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51738267025714,"sku":"C.E05.0457","price":20.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/df000223bcb57dab002fed7319895282.jpg?v=1788797406","url":"https:\/\/voomisupply.com\/products\/hertel-c-e05-0457-aircraft-extension-drill-bit-no-15","provider":"Voomi Supply","version":"1.0","type":"link"}
