Built from cobalt high-speed steel with a straw finish, it carries a 135-degree split point that is self-centering and web-thinned, reducing walking and cutting force at entry. The straight cylindrical shank measures 0.1470 inches in diameter, matching the wire size 26 drill designation. With a 6-inch overall length and a 1.875-inch spiral flute, this bit reaches into confined areas that standard-length bits cannot access. It conforms to NAS 907 standards and is suited for right-hand cutting with a two-flute, tapered web configuration.\u003c\/p\u003e\u003cp\u003eThis bit is used in applications requiring extended reach into structural assemblies, aircraft panels, or fabricated metal components. The cobalt construction handles harder materials including stainless steel, high-strength alloys, and hardened steels that would accelerate wear in standard HSS bits. It is appropriate for general-purpose production drilling in aerospace maintenance, sheet metal fabrication, and industrial maintenance environments. Machinists, aerospace technicians, and metal fabricators typically select this bit when standard extension lengths are insufficient and precision entry is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt construction with straw finish for improved heat and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point with web thinning reduces walking and entry force\u003c\/li\u003e\n\u003cli\u003eSelf-centering tip eliminates the need for a center punch on most surfaces\u003c\/li\u003e\n\u003cli\u003e6-inch overall length provides extended reach for deep or obstructed drilling locations\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank for use in standard drill chucks and drill motors\u003c\/li\u003e\n\u003cli\u003eConforms to NAS 907 standards for aircraft-grade tooling applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose aircraft extension drill bit in wire size 26 (0.1470 inches) for use in standard straight-shank drill chucks; suitable for drilling steel, stainless steel, and high-strength alloys in aerospace and industrial applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed and operated by machinists, aerospace technicians, and metal fabricators using standard hand drills, drill presses, or pneumatic drill motors with a compatible straight-shank chuck. Secure the shank fully in the chuck before operation and verify chuck key removal before starting. Use appropriate cutting fluid for hard materials to extend tool life and maintain hole quality. Inspect the cutting edges before each use and replace if chipping or excessive wear is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 26\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1470 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: 1.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1470 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\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\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\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\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: 0.03 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.E06.0373\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749338153266,"sku":"C.E06.0373","price":16.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/47a0dd86dbf42797d732a88c8248de0c.jpg?v=1788904684","url":"https:\/\/voomisupply.com\/products\/hertel-c-e06-0373-aircraft-extension-drill-bit-26-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
