Built from high-speed steel with an oxide finish, this bit measures 0.0635 inches in decimal diameter and carries a 135-degree split point that is self-centering and web-thinned for reduced thrust and cleaner entry. The spiral flute design with a tapered web configuration promotes efficient chip evacuation. It is a right-hand cutting, general-purpose tool intended for use by machinists, aerospace maintenance technicians, and aircraft service professionals who require extended reach without sacrificing hole quality or positional accuracy.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for aerospace maintenance, sheet metal work, and general fabrication applications where standard-length bits cannot access the work area. The 6-inch overall length and 0.875-inch flute length make it practical for drilling through assemblies, structural panels, and layered materials in both production and field service environments. It meets NAS 907 standards, making it appropriate for use in aerospace and defense maintenance contexts. The straight cylindrical shank fits standard drill chucks without adapters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge size 52 (0.0635 inches decimal diameter) for precise small-diameter drilling\u003c\/li\u003e\n\u003cli\u003e135-degree split point with self-centering geometry reduces walking and improves positional accuracy\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web construction lowers cutting thrust and extends tool life\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with oxide finish provides wear resistance for general-purpose use\u003c\/li\u003e\n\u003cli\u003e6-inch overall length delivers extended reach into confined or deep work areas\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 standard for aerospace-grade 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 compatible with standard straight-cylindrical shank drill chucks.

Secure the straight shank firmly in the drill chuck before operation and confirm the workpiece is properly clamped. Apply appropriate cutting fluid when drilling ferrous materials to reduce heat buildup and extend bit life. Follow all applicable safety standards and shop procedures when operating rotary cutting tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 52\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.0635 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: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0635 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\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\u003eSelf-Centering\u003c\/strong\u003e: Yes\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.E03.0161\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730663801138,"sku":"C.E03.0161","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cf89de31863864ce61556f3b06ea527c.jpg?v=1788721081","url":"https:\/\/voomisupply.com\/products\/hertel-c-e03-0161-aircraft-extension-drill-bit-52-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
