Built from high-speed steel with an oxide finish, it measures 12 inches in overall length and features a 1.25-inch spiral flute with a 135-degree split point. The self-centering split point reduces walking on initial contact, and web thinning lowers thrust requirements on entry. The straight cylindrical shank seats directly into standard drill chucks. This bit is installed by aircraft technicians, machinists, and maintenance professionals requiring extended reach in tight or deep-clearance drilling situations.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for general-purpose drilling in metal, composite, and similar materials where extended reach is required. The 12-inch overall length makes it well-suited for drilling through structural members, bulkheads, panels, or assemblies that would otherwise block a standard-length bit. It conforms to NAS 907 standards, making it appropriate for aerospace maintenance and overhaul work as well as general metalworking and fabrication environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 43 wire gauge size, 0.0890 inch decimal diameter\u003c\/li\u003e\n\u003cli\u003e12-inch overall length for extended reach in deep or obstructed drilling locations\u003c\/li\u003e\n\u003cli\u003e135-degree split point with self-centering geometry reduces bit walking on entry\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web lowers cutting thrust and heat buildup\u003c\/li\u003e\n\u003cli\u003eOxide finish on high-speed steel construction resists heat and light corrosion during service\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with two flutes for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eConforms to NAS 907 standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose aircraft extension drill bit for use in standard straight-shank drill chucks; compatible with any chuck accepting a 0.0890-inch straight cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSecure the straight cylindrical shank firmly in a drill chuck rated for the shank diameter before operation. Ensure workpiece is clamped or fixtured to prevent movement during drilling. Always wear appropriate eye protection and follow applicable shop safety procedures when operating drilling equipment. Inspect the bit for wear or damage before each use and discard any bit showing cracks, chipped flutes, or deformed geometry.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 43\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.0890 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.25 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: 0.0890 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered Web-Thinned\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\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.E05.0226\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51736173412658,"sku":"C.E05.0226","price":20.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f2b4ae635176c7ab38711824f60e330c.jpg?v=1788776337","url":"https:\/\/voomisupply.com\/products\/hertel-c-e05-0226-aircraft-extension-drill-bit-no-43","provider":"Voomi Supply","version":"1.0","type":"link"}
