The bit measures 17\/64 inch (0.2656 inch decimal) in diameter with a 12-inch overall length, making it well suited for drilling into recessed or hard-to-access areas where standard-length bits cannot reach. The 135-degree split point is self-centering, reducing the need for a center punch and minimizing walking on startup. An oxide finish provides a base level of surface hardness and lubricity. This bit is typically installed by machinists, aircraft maintenance technicians, and industrial tradespeople working with drill presses or hand-held power drills.\u003c\/p\u003e\n\u003cp\u003eThis aircraft extension drill bit is designed for general-purpose drilling in steel, aluminum, and similar metals where extended reach is required. The 12-inch length is particularly useful for drilling through structural panels, bulkheads, ductwork, or other assemblies with limited bit clearance. The straight cylindrical shank is compatible with standard drill chucks. Two right-hand spiral flutes clear chips efficiently across the 2-7\/8-inch (2.875-inch) flute length. The tapered web and web-thinned geometry reduce cutting resistance and improve hole entry performance in production and repair environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e17\/64 inch (0.2656 inch) diameter with 12-inch overall length for deep-reach access\u003c\/li\u003e\n  \u003cli\u003e135-degree split point is self-centering for accurate hole starts without a center punch\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability in ferrous and non-ferrous metal drilling\u003c\/li\u003e\n  \u003cli\u003eOxide finish for added surface hardness and reduced friction\u003c\/li\u003e\n  \u003cli\u003eTwo right-hand spiral flutes with tapered, web-thinned geometry for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard drill chucks\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 drill chucks accepting a 17\/64-inch straight cylindrical shank.

Secure the straight shank firmly in the chuck before operation and verify the drill is set to right-hand rotation. Use appropriate cutting fluid when drilling ferrous metals to prolong tool life and improve finish quality. Inspect the cutting edges for wear or chipping before each use and replace the bit if the split point shows signs of dulling.\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 (2.875 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: 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\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 Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.1 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.E05.0675\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51740486140210,"sku":"C.E05.0675","price":24.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9178c9ad22197534993010d4a3929058.jpg?v=1788825335","url":"https:\/\/voomisupply.com\/products\/hertel-c-e05-0675-aircraft-extension-drill-bit-17-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
