Built to wire gauge size No. 12 with a decimal diameter of 0.1890 inches, this bit features a 135-degree split point that self-centers on contact, reducing walking and the need for a center punch. The straw finish indicates the cobalt alloy composition and provides moderate heat resistance. At 6 inches overall length, it reaches into areas that standard-length bits cannot access. Licensed HVAC, metalworking, and maintenance technicians regularly specify cobalt extension bits for confined-space drilling tasks.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for use on stainless steel, hardened steel, cast iron, titanium, and other difficult-to-machine materials found in aerospace and heavy industrial environments. The extended length makes it appropriate for drilling through structural members, deep cavities, or stacked materials where clearance is limited. It meets NAS 907 standards, making it appropriate for aerospace maintenance and manufacturing workflows where material traceability and dimensional tolerance are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge size No. 12 with 0.1890 inch decimal diameter for precise hole sizing\u003c\/li\u003e\n\u003cli\u003e135-degree split point with self-centering geometry reduces bit walking without a center punch\u003c\/li\u003e\n\u003cli\u003eCobalt tool material with straw finish for improved heat and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003e6 inch overall length provides extended reach into confined or deep work areas\u003c\/li\u003e\n\u003cli\u003e2.3125 inch spiral flute length with web-thinned, tapered web for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction with straight-cylindrical shank for standard chuck compatibility\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 standard for aerospace-grade dimensional and material 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 standard straight-shank drill chucks; conforms to NAS 907 standards for aerospace maintenance and industrial machining applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed and operated by machinists, maintenance technicians, and aerospace service professionals using standard drill presses, magnetic drills, or hand-held power drills with a compatible straight-shank chuck. Secure the workpiece firmly before drilling and use cutting fluid appropriate for the base material to extend bit life and manage heat buildup. Inspect the cutting edges before each use and discard the bit if chipping or excessive wear is observed. Follow applicable shop safety standards and material-specific drilling procedures when working with hardened or exotic alloys.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDecimal Diameter\u003c\/strong\u003e: 0.1890 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\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\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\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: 0.1890 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 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: 0.04 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.E06.0480\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51735019651378,"sku":"C.E06.0480","price":17.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a3b5929b4210fb5d3e5e6e3ece8aaebc.jpg?v=1788769261","url":"https:\/\/voomisupply.com\/products\/hertel-c-e06-0480-aircraft-drill-bit-no-12-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
