Built from high speed steel with an oxide finish, this bit features a 135-degree split point that is self-centering and web-thinned for reduced thrust and cleaner entry without a pilot hole. The straight-cylindrical shank measures 0.1695 inches in diameter, matching the wire size 18 designation. With a 2.125-inch spiral flute length and 6-inch overall length, it reaches into cavities and recessed work areas that standard-length bits cannot access. Right-hand cutting direction. Licensed trades and sheet metal professionals rely on this geometry for consistent, accurate holes in tight quarters.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for aircraft-structure repair, sheet metal work, and general-purpose metal drilling where extended reach is required. The NAS 907 Type B standard compliance makes it appropriate for aerospace maintenance environments as well as commercial and industrial fabrication shops. The tapered web configuration reduces walking and improves chip evacuation on through-holes in steel, aluminum, and similar materials. It installs into any standard drill chuck or right-angle drill accepting a 0.1695-inch straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point with web thinning for self-centering entry and reduced drilling thrust\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length provides extended reach into recessed and deep work areas\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across general-purpose metal drilling\u003c\/li\u003e\n  \u003cli\u003eOxide finish improves lubricity and provides basic corrosion resistance during storage\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration promotes efficient chip evacuation on spiral flutes\u003c\/li\u003e\n  \u003cli\u003eNAS 907 Type B compliant for aerospace and structural maintenance applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct specification drill for applications requiring a wire size 18, 0.1695-inch diameter straight-shank aircraft extension drill bit meeting NAS 907 Type B standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, sheet metal mechanics, aircraft maintenance technicians, and general trades using standard drill presses, hand drills, or right-angle drills. Secure the straight-cylindrical shank firmly in the chuck before use and verify the bit runs true to avoid oversize holes or premature wear. Use appropriate cutting fluid for steel applications to extend tool life. Follow applicable workplace safety and FAA or facility maintenance protocols when drilling aircraft structure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1695 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: 2.125 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\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\u003eSelf-Centering\u003c\/strong\u003e: Yes\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: 0.1695 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0007 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 906\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: NAS 907 Type B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CHICAGO-LATROBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 11048\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51735027548466,"sku":"11048","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/127faed2987d64b36e2dec26dd95426b_1d95dd05-4e78-4e8c-a68c-23a60ca6bb50.jpg?v=1788769398","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-11048-aircraft-extension-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
