Manufactured from cobalt tool steel, this bit handles harder materials and higher heat without losing its edge. The 135-degree split point is self-centering, eliminating the need for a center punch and reducing walking on smooth or curved surfaces. The straw finish is standard on cobalt tooling and indicates proper heat treatment. At 6 inches in overall length, this bit delivers the extended reach required for airframe, structural, and industrial drilling work where a standard-length bit cannot access the workpoint.\u003c\/p\u003e\u003cp\u003eThis bit is suited for drilling in steel, stainless steel, aluminum, and other hard materials encountered in aerospace, HVAC fabrication, sheet metal, and general industrial applications. The extended 6-inch overall length makes it the right tool for drilling through structural members, deep flanges, or stacked material where access is obstructed. It is installed and used by aviation maintenance technicians, sheet metal workers, HVAC installers, and industrial maintenance mechanics. The straight cylindrical shank fits standard drill chucks without any adapter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt tool steel construction for high heat resistance and extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point with self-centering geometry reduces walking and eliminates center punch requirement\u003c\/li\u003e\n\u003cli\u003e6-inch overall length provides extended reach for deep or obstructed drilling locations\u003c\/li\u003e\n\u003cli\u003e7\/8-inch spiral flute length with right-hand cutting direction and web-thinned tapered web for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraw finish indicates proper cobalt heat treatment\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 general purpose aircraft extension drill bit for use in any standard drill chuck accepting a 0.0635-inch straight cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed in a standard drill motor or drill press by a qualified technician or mechanic. Ensure the drill chuck is fully tightened before operation and that the workpiece is firmly secured. Use appropriate cutting fluid when drilling stainless steel or hard alloys to extend tool life and maintain cut quality. Follow applicable shop safety standards and any relevant airframe maintenance manual procedures when used in aerospace applications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 52\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0635 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: 0.875 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0635 inches\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\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\u003eUNSPSC Code\u003c\/strong\u003e: 23241637\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.E06.0161\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":67912754692402,"sku":"C.E06.0161","price":18.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aae97adf8248d1f1a2a3b12380facdac.jpg?v=1791239441","url":"https:\/\/voomisupply.com\/products\/hertel-c-e06-0161-aircraft-extension-drill-bit-size-52-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
