Built from high-speed steel with an oxide finish, it is designed for general-purpose drilling in aerospace and industrial applications where extended reach is required. The 6-inch overall length and 3.75-inch spiral flute give technicians access to deep or obstructed hole locations that standard-length bits cannot reach. Two right-hand flutes provide efficient chip evacuation, and the self-centering split point reduces walking on entry without requiring a center punch.\u003c\/p\u003e\u003cp\u003eThis bit is suited for use in aircraft maintenance, sheet metal fabrication, and structural assembly work where access to recessed or tight areas is a common job requirement. The straight cylindrical shank seats cleanly in standard drill chucks and right-angle drill attachments frequently used in aviation and industrial trade environments. It is intended for installation by aircraft mechanics, machinists, and experienced trade professionals working to NAS 907 standards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter W size (0.3860 inches) with 135-degree split point for self-centering entry\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces thrust and improves penetration efficiency\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with oxide finish for wear resistance\u003c\/li\u003e\n\u003cli\u003e3.75-inch spiral flute length supports deep-reach drilling applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction with two flutes for effective chip removal\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 standard for aircraft drill bit performance\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 and right-angle drill attachments used in aerospace, sheet metal, and industrial drilling applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified mechanics or machinists familiar with drilling procedures for aerospace and structural materials. Secure the workpiece before drilling and confirm the shank is fully seated and locked in the chuck before operation. Follow applicable shop safety procedures and any relevant NAS or OEM specifications for the material being drilled. Inspect the cutting edges for wear or damage before each use and replace the bit if chipping or excessive dullness is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.3860 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: 3.75 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: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\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: 0.3860 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 Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelf-Centering\u003c\/strong\u003e: Yes\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: 0.15 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.E03.0980\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51729324802354,"sku":"C.E03.0980","price":51.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/228a06da145bfb28d20ff70071012ed2.jpg?v=1788702917","url":"https:\/\/voomisupply.com\/products\/hertel-c-e03-0980-aircraft-extension-drill-bit-letter-w","provider":"Voomi Supply","version":"1.0","type":"link"}
