Built from high-speed steel with an oxide finish, it features a 135-degree split point for self-centering starts and reduced walking on flat or curved surfaces. At 6 inches overall length with a 2.1875-inch spiral flute, it reaches into tight or recessed areas where standard-length bits cannot. The straight cylindrical shank measures 0.1800 inches in diameter, matching the 0.1800-inch decimal bore size. The web-thinned, tapered web configuration reduces thrust during drilling and improves chip evacuation in through-hole and blind-hole work.\u003c\/p\u003e\u003cp\u003eThis bit is suited for general-purpose metal drilling in aircraft structure, sheet metal, and fabrication applications. The extended length makes it practical for drilling through stacked materials, structural members, or panels where access is limited. It is commonly used by aviation maintenance technicians, sheet metal fabricators, and industrial maintenance mechanics. Right-hand cutting direction and two-flute spiral design keep it compatible with standard drill presses, hand drills, and right-angle drill motors used in production and repair environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge size 15 with 0.1800-inch decimal diameter for precise bore sizing\u003c\/li\u003e\n\u003cli\u003e135-degree split point with self-centering geometry reduces walking and pilot-hole requirements\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web lowers drilling thrust and improves chip flow\u003c\/li\u003e\n\u003cli\u003e6-inch overall length with 2.1875-inch spiral flute for extended-reach access\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with oxide finish for wear resistance in general-purpose metal drilling\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 standard for aircraft drill bit performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose aircraft extension drill bit conforming to NAS 907 standards, suitable for use in standard straight-shank drill chucks across hand drills, drill presses, and right-angle drill motors accepting a 0.1800-inch shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists, aviation maintenance technicians, or sheet metal fabricators familiar with drill speed and feed rates for the workpiece material. Secure the workpiece firmly before drilling to prevent movement that can cause bit breakage or oversized holes. Inspect the bit for chipping or wear before each use and replace if the cutting edges are degraded. Follow applicable workplace safety standards and aviation maintenance documentation when drilling structural aircraft components.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.1800 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: 2.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1800 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\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\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.E03.0457\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51731006882098,"sku":"C.E03.0457","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f42129b70c6f9a1d8e9b5c8e446c4b90.jpg?v=1788725765","url":"https:\/\/voomisupply.com\/products\/hertel-c-e03-0457-aircraft-extension-drill-bit-15-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
