Built to Series 912 specifications and compliant with NAS 907 Type B standards, this bit features a 135-degree split point with web thinning for self-centering entry and reduced thrust on initial penetration. The 1\/8 inch diameter with a 12 inch overall length gives technicians the reach needed for structural, sheet metal, and confined-space drilling tasks. An oxide finish provides corrosion resistance and reduces friction during cutting. Right-hand spiral flutes measure 1.625 inches in length and evacuate chips efficiently during operation.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for use in aerospace, aviation maintenance, HVAC sheet metal fabrication, electrical conduit work, and general metalworking where extended reach is required. The straight-cylindrical shank seats securely in standard drill chucks. Its general-purpose tool performance rating makes it appropriate for production environments and field service alike. Professionals in sheet metal, structural assembly, and mechanical service trades rely on extension drill bits like this when working through deep panels, framing cavities, or layered assemblies where a standard jobber-length bit falls short.\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 and reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003e12 inch overall length for extended-reach drilling in confined or deep-access locations\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eOxide finish reduces friction and provides light corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks\u003c\/li\u003e\n  \u003cli\u003eNAS 907 Type B compliant for aerospace and structural applications\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration with 2-flute right-hand spiral for efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose extension drill bit for use in standard 3-jaw drill chucks accepting a 1\/8 inch straight-cylindrical shank.

Secure the workpiece before drilling and ensure the drill chuck is properly tightened on the shank before operation. Reduce feed pressure at breakthrough to prevent bit deflection or workpiece damage. Use appropriate cutting fluid for harder materials to extend tool life and maintain dimensional tolerance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 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: 1-5\/8 inches (1.6250 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\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 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 (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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 inches\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\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: 11100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51753000206642,"sku":"11100","price":18.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9cfe4602e4dc52ea3b0ff0cce686eaae_cde435a8-ebb4-4204-bc6d-8e251094e375.jpg?v=1788932016","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-11100-aircraft-extension-drill-bit-1-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
