At 12 inches overall length with a 17\/64 inch diameter, this bit delivers access to deep or recessed work areas that standard-length bits cannot reach. The 135-degree split point is self-centering, reducing the need for a center punch and minimizing walking on entry. The straw finish indicates heat-treated cobalt steel construction, suited for use on stainless steel, high-nickel alloys, and other tough materials common in aircraft, industrial, and fabrication environments. Licensed machinists, A and P mechanics, and maintenance technicians are the typical users.\u003c\/p\u003e\n\u003cp\u003eThis aircraft extension drill bit is built for general-purpose drilling in production and MRO settings where material hardness or workpiece geometry demands both reach and cutting performance. The 2-7\/8 inch spiral flute length provides efficient chip evacuation during deep or angled drilling. The straight cylindrical shank is compatible with standard drill chucks used in handheld drills and drill presses alike. Typical applications include airframe work, structural fabrication, and hard-metal drilling in industrial maintenance environments where standard-length bits are inadequate.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e17\/64 inch (0.2656 inch) diameter with matching straight cylindrical shank for secure chuck grip\u003c\/li\u003e\n  \u003cli\u003e135-degree split point is self-centering and web-thinned for reduced thrust and cleaner entry\u003c\/li\u003e\n  \u003cli\u003e12 inch overall length provides extended reach for deep or confined drilling locations\u003c\/li\u003e\n  \u003cli\u003eCobalt tool material with straw finish for heat resistance and durability in hard metals\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting, 2-flute spiral design with tapered web configuration for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 standards for aircraft-grade drill bit performance\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 on handheld drills and drill presses.

Ensure the workpiece is securely fixtured before drilling to prevent movement. Use appropriate cutting fluid when drilling stainless steel or high-nickel alloys to manage heat buildup and extend bit life. Never exceed the rated speed range appropriate for the bit diameter and workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 17\/64 inch (0.2656 inch)\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: 2-7\/8 inches (2.8750 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\u003eSelf-Centering\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Straw\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: 17\/64 inch (0.2656 inch)\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\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: 0.01 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.E07.0675\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51788040470834,"sku":"C.E07.0675","price":40.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4c10946bb678588ea09f6e3d2f06bc86.jpg?v=1789222560","url":"https:\/\/voomisupply.com\/products\/hertel-c-e07-0675-aircraft-extension-drill-bit-17-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
