It carries a wire gauge size of 9 (0.1960 inches decimal) and a 135-degree split point that self-centers on contact, reducing the need for a center punch. The straw finish is characteristic of cobalt tooling and provides mild heat resistance during high-speed drilling. At 12 inches overall length with a 2.4375-inch spiral flute, this bit is suited for deep-reach applications that demand rigidity without sacrificing chip evacuation.\u003c\/p\u003e\u003cp\u003eAircraft extension drill bits like the C.E07.0498 are used in aerospace fabrication, structural metalwork, and industrial maintenance where access is restricted or hole depth exceeds the reach of standard jobber-length bits. The right-hand spiral flute and web-thinned, tapered web construction allow efficient cutting in steel, stainless, aluminum, and other alloys. This is a general-purpose bit appropriate for machine or handheld drill use in both shop and field environments where NAS 907 tooling standards apply.\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 metals\u003c\/li\u003e\n\u003cli\u003e135-degree split point with self-centering geometry eliminates the need for a center punch\u003c\/li\u003e\n\u003cli\u003eExtended 12-inch overall length provides deep-reach access in confined or structural applications\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web reduces thrust force and improves cutting efficiency\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003eRight-hand, 2-flute spiral design promotes consistent chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose aircraft extension drill bit conforming to NAS 907 standards, suitable for use in standard drill chucks accepting a 0.1960-inch straight cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by machinists and metalworkers using handheld drills, drill presses, or CNC equipment. Secure the straight shank firmly in a keyed or keyless chuck before operation. Use appropriate cutting fluid or coolant when drilling hard alloys to manage heat buildup and extend tool life. Inspect the cutting edge for wear or chipping before each use and replace when performance degrades to avoid workpiece damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.1960 inches\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: 2.4375 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\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1960 inches\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 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: 0.92 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.E07.0498\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51727093432626,"sku":"C.E07.0498","price":35.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2743ba97996a47c7ce26211001c87c36.jpg?v=1788673195","url":"https:\/\/voomisupply.com\/products\/hertel-c-e07-0498-aircraft-drill-bit-wire-9-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
