Manufactured from high-speed steel with an oxide finish, it features a 135-degree split point that is self-centering and reduces the need for a center punch. The bit has a spiral flute with a web-thinned, tapered web configuration for improved chip evacuation. At 12 inches overall length and 0.2055 inches in diameter, it is sized for precision work in structural, aerospace, and general metalworking environments. Licensed HVAC, plumbing, and mechanical contractors often keep aircraft bits on hand for access drilling through framing and tight assemblies.\u003c\/p\u003e\u003cp\u003eThis bit is suited for right-hand cutting in ferrous and non-ferrous metals, plastics, and composite materials in residential and commercial construction or fabrication settings. The 12-inch overall length makes it effective for drilling through studs, joists, and sheet metal assemblies where standard-length bits cannot reach. The 2.5-inch flute length provides adequate chip clearance during extended-reach operations. It meets NAS 907 standards, making it appropriate for general-purpose aerospace and industrial drilling applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge size 5 (0.2055 inches) straight-cylindrical shank for standard chuck compatibility\u003c\/li\u003e\n\u003cli\u003e135-degree split point with self-centering geometry reduces walking on hard surfaces\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces cutting resistance and improves penetration rate\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with oxide finish for corrosion resistance and reduced friction\u003c\/li\u003e\n\u003cli\u003e12-inch overall length for deep-reach and extended-access drilling\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 standard for general-purpose aerospace and industrial use\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 3-jaw drill chucks accepting a 0.2055-inch straight-cylindrical shank.

Ensure the drill chuck is fully tightened before operation and that the workpiece is secured to prevent movement. When drilling through structural members, verify that no wiring, piping, or conduit is present behind the work surface before proceeding. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and reduce heat buildup.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.2055 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: 2.5 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2055 inches\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\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.E05.0522\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732386971954,"sku":"C.E05.0522","price":21.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3a8481e7e6139f22e893e185af8b2e38.jpg?v=1788742314","url":"https:\/\/voomisupply.com\/products\/hertel-c-e05-0522-aircraft-extension-drill-bit-135-pt","provider":"Voomi Supply","version":"1.0","type":"link"}
