Built from high-speed steel with an oxide finish, this bit features a 135-degree split point that is self-centering and reduces the need for a center punch. The web-thinned, tapered web construction lowers thrust and improves chip evacuation. At 6 inches overall length with a 2.1875-inch spiral flute, it gives technicians extra reach in confined or deep-hole scenarios. Two right-hand spiral flutes provide efficient cutting at wire gauge size 16, equal to 0.1770 inches in decimal. This bit meets NAS 907 standards and is suited for general-purpose production and maintenance work.\u003c\/p\u003e\u003cp\u003eThis bit is commonly used in aviation maintenance, HVAC sheet metal fabrication, electrical panel work, and any trade application requiring extended reach into tight or recessed areas. The straight cylindrical shank seats in standard drill chucks without adapters, making it a practical drop-in for cordless drills, drill presses, and hand-held pneumatic tools. It is appropriate for both production line use and service-call fieldwork where drilling through stacked materials or deep cavities is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point is self-centering, reducing walking on hard or curved surfaces\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces drilling thrust and improves chip clearing\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with oxide finish for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003e6-inch overall length provides extended reach for deep-hole and confined-space drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with two flutes for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 standard for aircraft-quality 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 accepting a 0.1770-inch diameter shank, suitable for use in metalworking, sheet metal, and aviation maintenance applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is intended for use by machinists, aviation maintenance technicians, sheet metal workers, and trade professionals operating drill presses, hand drills, or pneumatic drilling equipment. Secure the straight cylindrical shank firmly in the chuck before use and confirm runout is within acceptable limits to avoid bit deflection at extended length. Always wear appropriate eye protection and ensure the workpiece is clamped securely. Do not exceed the rated cutting speed for high-speed steel tooling on hardened materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.1770 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: 2.1875 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\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: 0.1770 inches\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\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\u003eStandard\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.E03.0450\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51734671786290,"sku":"C.E03.0450","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a5089615d24816d3165896079845985.jpg?v=1788764647","url":"https:\/\/voomisupply.com\/products\/hertel-c-e03-0450-aircraft-extension-drill-bit-16-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
