Built to a No. 35 wire gauge size (0.1100 inches decimal), it features a 135-degree split point that reduces walking and enables self-centering without a center punch. The straw finish cobalt construction resists heat buildup during extended drilling operations. With a 12-inch overall length and 1.5-inch spiral flute, this bit is suited to aerospace, fabrication, and maintenance applications where deep reach and precise entry are required. It meets NAS 907 standards and is installed by machinists, aircraft mechanics, and maintenance technicians.\u003c\/p\u003e\u003cp\u003eThis drill bit is sized for applications requiring a No. 35 wire gauge hole in ferrous metals, stainless steel, and high-temperature alloys. The extended 12-inch overall length is specifically intended for drilling through structural members, panels, or assemblies where a standard-length bit cannot access the work area. The right-hand spiral flute with web-thinned, tapered web configuration promotes efficient chip evacuation in deep-hole drilling scenarios common in aircraft and industrial maintenance work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 35 wire gauge size — 0.1100 inches decimal diameter\u003c\/li\u003e\n\u003cli\u003e135-degree split point with self-centering geometry reduces bit walking\u003c\/li\u003e\n\u003cli\u003eCobalt tool material with straw finish for heat resistance in hard materials\u003c\/li\u003e\n\u003cli\u003e12-inch overall length for extended reach in deep or confined drilling locations\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web for reduced thrust and improved chip flow\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 standard for aircraft-grade tooling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose aircraft extension drill bit compatible with standard straight-shank drill chucks sized for 0.1100-inch shank diameters.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is intended for use by qualified machinists, aircraft mechanics, or maintenance technicians operating hand-held or fixed drilling equipment. Secure the workpiece before drilling and confirm the drill chuck is properly tightened on the straight-cylindrical shank before operation. Use appropriate cutting fluid when drilling hard alloys or stainless steel to extend tool life and manage heat. Follow applicable workplace safety standards and equipment manufacturer guidelines during use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 35\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.1100 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: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1100 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\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: 0.03 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.E07.0279\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51738744455474,"sku":"C.E07.0279","price":31.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4c947eb21a5551dff64d2a929a02316.jpg?v=1788803745","url":"https:\/\/voomisupply.com\/products\/hertel-c-e07-0279-aircraft-extension-drill-bit-no-35","provider":"Voomi Supply","version":"1.0","type":"link"}
