The 12-inch overall length gives technicians the extended reach needed to access confined or obstructed bore locations where standard-length bits fall short. At 0.375 inches in diameter with a 135-degree split point, the bit self-centers on contact, reducing the need for a center punch and minimizing walking on hard surfaces. An oxide finish provides baseline lubricity and surface protection during cutting. This is a general-purpose tool suited for right-hand rotation in a standard or extended drill motor.\u003c\/p\u003e\n\u003cp\u003eThe 11116 is designed for use in aviation maintenance, structural fabrication, and industrial metalworking where extended reach is required. The 3.625-inch spiral flute length efficiently evacuates chips during deep-hole drilling. With a straight-cylindrical shank measuring 0.375 inches in diameter, it seats securely in standard drill chucks and drill press collets. The Series 912 designation identifies it as a NAS 907 Type B compliant tool, making it suitable for use in applications governed by that specification. A two-flute, web-thinned, tapered-web design reduces cutting resistance and supports controlled feed rates in ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point for self-centering entry without a pilot hole or center punch\u003c\/li\u003e\n  \u003cli\u003e12-inch overall length provides extended reach into deep or obstructed bore locations\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles general-purpose metal drilling across ferrous and non-ferrous stock\u003c\/li\u003e\n  \u003cli\u003eOxide finish adds surface lubricity and basic corrosion resistance during use\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered-web geometry reduces thrust requirements and cutting resistance\u003c\/li\u003e\n  \u003cli\u003eNAS 907 Type B compliant — suitable for aerospace and aviation maintenance applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style general-purpose extension drill bit compatible with standard drill chucks and collets accepting a 0.375-inch straight-cylindrical shank.

Ensure the shank is fully seated and the chuck is securely tightened before operation. Apply consistent feed pressure and use appropriate cutting fluid for the material being drilled to maximize bit life and hole quality. Inspect the cutting edges before each use and remove from service if the point shows signs of wear or chipping.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\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: 3.625 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, Self-Centering\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: 0.375 inches\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 -0.0010 inches\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  \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: 11116\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51733580022066,"sku":"11116","price":35.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9cfe4602e4dc52ea3b0ff0cce686eaae_1d00e6ea-2512-49ee-96fd-2486817c2b98.jpg?v=1788756536","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-11116-aircraft-extension-drill-bit-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
