With a 5\/32-inch (0.1563 inch) diameter, a 135-degree split point, and a straw finish, this bit is built for general-purpose drilling in hard metals including stainless steel, high-strength alloys, and aircraft-grade materials. The 6-inch overall length combined with a 2-inch spiral flute gives machinists and maintenance techs extended reach without sacrificing chip clearance or rigidity. Right-hand cutting direction and a straight cylindrical shank make it compatible with standard drill chucks.\u003c\/p\u003e\u003cp\u003eThis bit is suited for aerospace maintenance, sheet metal work, and structural repair tasks where access is restricted. The cobalt construction handles elevated heat generated when drilling hardened or abrasive materials. The self-centering split point reduces the need for a center punch and helps prevent walking on curved or coated surfaces. General-purpose tool performance makes it appropriate for job shops, MRO facilities, and field service environments working with high-strength base materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt construction with straw finish for heat resistance and extended tool life in hard metals\u003c\/li\u003e\n\u003cli\u003e135-degree split point for self-centering entry and reduced thrust force\u003c\/li\u003e\n\u003cli\u003e6-inch overall length provides extended reach into confined areas\u003c\/li\u003e\n\u003cli\u003e2-inch spiral flute length promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces cutting resistance\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, straight cylindrical shank fits standard drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose aircraft extension drill bit meeting NAS 907 standards, suitable for use in standard drill chucks and right-angle drill attachments accepting a 5\/32-inch straight cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is intended for use by machinists, aircraft maintenance technicians, and experienced metal fabricators. Secure the workpiece before drilling and use appropriate cutting fluid when drilling in stainless or high-strength alloys to manage heat buildup. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed. Follow applicable workplace safety standards and use appropriate PPE including eye protection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5\/32 inch (0.1563 inch)\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 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\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: 5\/32 inch (0.1563 inch)\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\u003eSelf-Centering\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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.E06.0397\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51787016896818,"sku":"C.E06.0397","price":15.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4b0e1efda59dc1f229bff1a46f257338.jpg?v=1789209038","url":"https:\/\/voomisupply.com\/products\/hertel-c-e06-0397-aircraft-extension-drill-bit-5-32-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
