Built from high-speed steel with an oxide finish, it measures 12 inches in overall length, making it well suited for drilling through airframes, sheet metal, structural panels, and similar tight-access assemblies. The 135-degree split point is self-centering, reducing the need for a center punch on most surfaces. The spiral flute design clears chips efficiently, and the web-thinned, tapered web configuration reduces thrust and minimizes walking at entry. This bit is handled by machinists, aviation maintenance technicians, and fabricators working with metal in confined locations.\u003c\/p\u003e\u003cp\u003eThis drill bit is built for general-purpose metal drilling applications where standard bit length is insufficient. It fits typical use cases in aerospace maintenance, HVAC sheet metal fabrication, electrical panel work, and structural steel applications where extended reach is required. The straight cylindrical shank accepts standard drill chucks without adapters. The right-hand cutting direction is compatible with all conventional drill motors and drill presses.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point is self-centering for accurate hole starts without a center punch\u003c\/li\u003e\n\u003cli\u003e12 inch overall length provides extended reach into deep or obstructed work areas\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction handles steel, aluminum, and most common metals\u003c\/li\u003e\n\u003cli\u003eOxide finish provides basic surface protection and reduces friction during cutting\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces drilling thrust and walking tendency\u003c\/li\u003e\n\u003cli\u003e2-flute spiral design promotes efficient chip evacuation from deep holes\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 or drill press accepting a 1\/16 inch straight cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed and operated by machinists, aviation maintenance technicians, and metal fabricators. Secure the workpiece firmly before drilling to prevent movement at the small diameter entry point. Use appropriate cutting fluid on harder metals to extend bit life and reduce heat buildup. Inspect the cutting edges before each use, as small-diameter high-speed steel bits are susceptible to tip breakage if subjected to side load or excessive feed pressure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1\/16 inch (0.0625 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: 7\/8 inch (0.875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/16 inch (0.0625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\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\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Oxide\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\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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.E05.0159\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51734697574706,"sku":"C.E05.0159","price":18.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a651fa1265bb5785c0c982e5f10d6a85.jpg?v=1788765155","url":"https:\/\/voomisupply.com\/products\/hertel-c-e05-0159-aircraft-extension-drill-bit-1-16-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
