Built from high-speed steel with an oxide finish, it cuts a 0.209-inch diameter hole using a 135-degree split point that self-centers on contact and reduces walking on curved or angled surfaces. The web-thinned, tapered-web construction lowers thrust requirements and improves chip evacuation through the 2.5-inch spiral flute length. At 6 inches overall length, it gives technicians the reach needed for recessed or obstructed drilling applications in metal fabrication and aircraft maintenance work.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for right-hand drilling in ferrous and non-ferrous metals in general-purpose shop, MRO, and aerospace maintenance environments. The straight-cylindrical shank seats securely in standard drill chucks and drill motors. Its extended reach makes it practical for structural assemblies, tight bays, and applications where standard jobber-length bits cannot access the workpoint. The 0.209-inch diameter corresponds to wire gauge size 4. It conforms to NAS 907 Type B standards, making it appropriate for aerospace and precision metalworking applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point self-centers on contact, reducing bit walk and improving hole accuracy\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered-web geometry lowers required thrust and aids chip evacuation\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with oxide finish provides wear resistance for general-purpose metal drilling\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length with 2.5-inch flute length extends reach into recessed and obstructed workpoints\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type B standards for aerospace and precision metalworking use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use drill bit for applications requiring a 0.209-inch diameter, NAS 907 Type B compliant aircraft extension drill in general-purpose metal drilling setups.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this drill bit is performed by machinists, aircraft maintenance technicians, and metalworkers using standard drill motors or drill presses. Secure the straight-cylindrical shank firmly in the chuck before operation and verify chuck key is removed before starting the tool. Apply appropriate cutting fluid for the workpiece material to extend bit life and improve hole finish. Inspect the cutting edges for wear or damage before each use and replace the bit if the point shows chipping or rounding.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.209 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: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.209 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\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: 11034\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51736799936818,"sku":"11034","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/127faed2987d64b36e2dec26dd95426b_6edce675-da1f-4755-829d-93ac02378b7c.jpg?v=1788780518","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-11034-aircraft-extension-drill-bit-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
