Built to a 135-degree split point with web thinning, it self-centers on contact and reduces the force needed to start a hole without a center punch. The straw finish indicates heat treatment appropriate for cobalt-grade tooling. With a straight cylindrical shank measuring 0.0960 inches in diameter and a 6-inch overall length, this bit fits standard drill chucks and is well suited for aerospace, sheet metal, and structural fabrication work where extended reach is required.\u003c\/p\u003e\u003cp\u003eThis bit is intended for right-hand cutting in ferrous metals, stainless steel, hard alloys, and similar materials that generate high heat and wear through conventional high-speed steel tooling. The 1.375-inch spiral flute evacuates chips efficiently during extended-reach drilling. A tapered web and 2-flute configuration keep cutting geometry consistent through the full flute length. This is a general-purpose tool appropriate for production drilling, maintenance, and repair applications in fabrication shops, aerospace facilities, and industrial maintenance environments. A licensed machinist, toolmaker, or experienced fabricator would be the typical user.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt tool material resists heat and wear when drilling hard metals and alloys\u003c\/li\u003e\n\u003cli\u003e135-degree split point with web thinning for self-centering starts without a center punch\u003c\/li\u003e\n\u003cli\u003e6-inch overall length provides extended reach into recessed or deep-clearance locations\u003c\/li\u003e\n\u003cli\u003eStraw finish heat treatment appropriate for high-performance cobalt drill stock\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute evacuates chips and reduces heat buildup during drilling\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 standard for aircraft extension drill bits\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style aircraft extension drill bit conforming to NAS 907, suitable for use in standard straight-shank drill chucks and driver systems accepting a 0.0960-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed and used by machinists, fabricators, and aerospace maintenance technicians. Secure the straight cylindrical shank firmly in a compatible drill chuck before use. Always use appropriate cutting fluid for the workpiece material to extend bit life and reduce heat. Inspect the cutting edges and web for wear or chipping before each use and do not operate a damaged bit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 41\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.0960 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: 1.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0960 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\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 Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelf-Centering\u003c\/strong\u003e: Yes\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: 0.01 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.E06.0244\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51738753106226,"sku":"C.E06.0244","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/819b1e84787519b13ae1915a57be7eb9.jpg?v=1788803887","url":"https:\/\/voomisupply.com\/products\/hertel-c-e06-0244-aircraft-drill-bit-no-41-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
