Built from high-speed steel with an oxide finish, this bit features a 135-degree split point angle that reduces walking and improves entry accuracy without a center punch. The 6-inch overall length provides the extended reach required in tight or deep-access drilling scenarios. With a straight cylindrical shank measuring 0.0520 inches in diameter and a spiral flute length of 0.8750 inches, the bit is suited for right-hand cutting in general-purpose applications. A tapered web configuration with web thinning reduces thrust and improves chip evacuation. Licensed tradespeople and aerospace maintenance technicians are the primary installers.\u003c\/p\u003e\u003cp\u003eThis aircraft extension drill bit is intended for use in aviation maintenance, sheet metal fabrication, and precision manufacturing environments where standard-length bits cannot reach the work surface. The size 55 wire gauge designation and 0.0520-inch decimal diameter make it appropriate for small-diameter, close-tolerance hole drilling in steel, aluminum, and similar materials. Its general-purpose performance rating and NAS 907 standard compliance make it a reliable option for both production and repair work requiring extended reach and controlled entry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge size 55, 0.0520-inch decimal diameter for close-tolerance small-bore drilling\u003c\/li\u003e\n\u003cli\u003e135-degree standard point angle reduces bit walking on entry\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web configuration lowers drilling thrust and improves chip flow\u003c\/li\u003e\n\u003cli\u003e6-inch overall length provides extended reach in confined or deep-access work areas\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with oxide finish for general-purpose durability\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 standard for aerospace and industrial 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 suitable for use with standard straight-shank drill chucks in hand drills, drill presses, and pneumatic drilling equipment used in aerospace maintenance and sheet metal fabrication.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of this bit is performed by licensed aerospace technicians, machinists, or qualified sheet metal workers. Secure the straight cylindrical shank firmly in an appropriate drill chuck before use and verify concentricity to prevent runout. Follow applicable workplace safety standards and any relevant NAS or OEM drilling procedures for the material being worked. Never exceed the rated speed range for the bit diameter and material combination.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 55\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0520 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: 0.8750 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0520 inches\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\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\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\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\u003eStandards\u003c\/strong\u003e: NAS 907\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.E02.0132\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51787791925554,"sku":"C.E02.0132","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e3c018f6d052b293312aaea2f84b1fc7.jpg?v=1789219029","url":"https:\/\/voomisupply.com\/products\/hertel-c-e02-0132-aircraft-extension-drill-bit-55-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
