Built to wire gauge size 11, the bit measures 0.1910 inch in decimal diameter and runs 6 inches in overall length. The 135-degree split point is self-centering, which eliminates the need for a center punch in most applications. A straw finish indicates the cobalt content and helps resist heat buildup during extended drilling cycles. Licensed HVAC techs, aircraft maintenance technicians, and industrial trades reach for this bit when material hardness demands more than standard high-speed steel.\u003c\/p\u003e\u003cp\u003eThis bit is suited for aircraft-grade aluminum, stainless steel, and structural alloys found in aerospace maintenance, sheet-metal fabrication, and industrial manufacturing environments. With a 2.3125-inch spiral flute length and a straight cylindrical shank measuring 0.1910 inch in diameter, it seats directly into standard drill chucks and right-angle drill attachments common in tight-access applications. Right-hand cutting direction is standard for conventional drill presses and handheld power drills. The tapered web with web thinning reduces thrust force and improves chip evacuation in deep-hole work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge size 11, 0.1910 inch decimal diameter for precision sizing\u003c\/li\u003e\n\u003cli\u003e135-degree split point with self-centering geometry — no center punch required\u003c\/li\u003e\n\u003cli\u003eCobalt construction with straw finish for heat resistance in hard-material drilling\u003c\/li\u003e\n\u003cli\u003e2.3125-inch spiral flute length with tapered, web-thinned design for efficient chip clearing\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank at 0.1910 inch diameter fits standard chucks and right-angle drives\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-specification aircraft extension drill bit conforming to NAS 907, compatible with standard straight-shank drill chucks and right-angle drill attachments used in aerospace, sheet-metal, and general industrial applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by a qualified technician familiar with drilling practices for hard materials. Secure the workpiece fully before drilling and confirm chuck fit with the 0.1910-inch straight shank before operation. Use appropriate cutting fluid or coolant when drilling stainless steel or high-temperature alloys to extend bit life and maintain dimensional accuracy. Inspect the cutting edges before each use and retire the bit at the first sign of chipping or excessive wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1910 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: 2.3125 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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1910 inches\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\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: 0.04 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.E06.0485\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51755724472626,"sku":"C.E06.0485","price":17.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2926f8e4a4613904d6b0036297504e6d.jpg?v=1788958621","url":"https:\/\/voomisupply.com\/products\/hertel-c-e06-0485-aircraft-drill-bit-size-11-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
