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. The straight-cylindrical shank measures 0.0935 inches in diameter, and the two-flute spiral design produces efficient chip evacuation. The 1.375-inch flute length and 12-inch overall length make it well suited for accessing fastener locations in tight or recessed areas. This is a general-purpose, right-hand cutting bit conforming to NAS 907 Type B standards.\u003c\/p\u003e\n\u003cp\u003eThe 11165 is used in aviation, aerospace, and industrial maintenance applications where standard-length drill bits cannot reach. The extended 12-inch overall length allows technicians to drill through structural panels, frames, and assemblies without disassembly. It is a common choice for aircraft mechanics, MRO shops, and industrial maintenance teams working on riveted or bolted structures. The 135-degree split point geometry reduces walking on hard surfaces, making it effective on steel, aluminum, and similar materials typical in these environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire size 41 with 0.0960 inch decimal diameter and tight tolerance of +0.0000 to -0.0005 inches\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 configuration lowers cutting resistance and thrust force\u003c\/li\u003e\n  \u003cli\u003e12-inch overall length provides extended reach for deep or obstructed drilling locations\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with oxide finish for general-purpose metal drilling\u003c\/li\u003e\n  \u003cli\u003eConforms to NAS 907 Type B standards for aircraft and industrial use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style general-purpose aircraft extension drill bit conforming to NAS 907 Type B, suitable for use in standard drill chucks accepting a 0.0935-inch straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, aircraft mechanics, or industrial maintenance technicians using a hand drill, drill press, or pneumatic drill with a compatible chuck. Secure the workpiece and verify chuck grip on the straight shank before operation. Use appropriate cutting fluid for ferrous materials to extend bit life and maintain dimensional tolerance. Inspect the cutting edges before each use and replace if chipping or wear is observed.\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: 41\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0960 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0935 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: 1.375 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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, 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 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 -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 912\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: NAS 907 Type B\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: 11165\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51749264326962,"sku":"11165","price":21.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9cfe4602e4dc52ea3b0ff0cce686eaae_bbf53f0f-1d89-47a8-b385-5eca515b69e6.jpg?v=1788903762","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-11165-aircraft-extension-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
