Built from high-speed steel with an oxide finish, it delivers reliable cutting performance in steel, aluminum, and similar materials. The 135-degree split point with web thinning allows for self-centering entry without a center punch, reducing setup time. At 12 inches overall length with a 2.4375-inch spiral flute, this bit is sized for reaching into recessed cavities, structural panels, and deep assemblies common in fabrication, aerospace maintenance, and industrial trades.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for right-hand drilling in professional shop and field environments. The straight cylindrical shank fits standard drill chucks without adapters. Its general-purpose classification and NAS 907 compliance make it appropriate for metal fabrication shops, aviation maintenance facilities, HVAC and mechanical contractors drilling through structural members, and industrial maintenance technicians requiring extended reach. The tapered web configuration reduces thrust load and heat buildup during drilling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 9 wire size, 0.1960 inch decimal diameter — precise sizing for close-tolerance hole requirements\u003c\/li\u003e\n\u003cli\u003e135-degree split point with web thinning for self-centering drilling, no pilot hole needed\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with oxide finish for wear resistance and corrosion inhibition\u003c\/li\u003e\n\u003cli\u003e12-inch overall length provides extended reach into deep assemblies and structural panels\u003c\/li\u003e\n\u003cli\u003eSpiral flute, 2.4375-inch flute length promotes chip evacuation during extended-depth cuts\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 standard for aircraft-grade tooling requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose aircraft extension drill bit compatible with any standard drill chuck accepting a 0.1960-inch straight cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed and operated by machinists, maintenance technicians, and trade professionals using portable or bench-mounted drilling equipment. Secure the straight cylindrical shank fully in the chuck before operation to prevent runout. Use appropriate cutting fluid when drilling ferrous metals to extend tool life and manage heat. Inspect the cutting edges and web for damage before each use and replace the bit if chipping or excessive wear is present.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 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\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\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\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\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: 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.E05.0498\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51731000557874,"sku":"C.E05.0498","price":20.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c31983a3272929de37b21bcbde079ff3.jpg?v=1788725674","url":"https:\/\/voomisupply.com\/products\/hertel-c-e05-0498-aircraft-drill-bit-no-9-hss-12-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
