Built from high-speed steel with an oxide finish, it carries a wire gauge size of 60, which corresponds to a decimal diameter of 0.0400 inches. The straight-cylindrical shank measures 0.0980 inches in diameter, and the spiral flute length is 0.6875 inches. The 135-degree split point with web thinning promotes accurate hole entry and reduces walking on hard or layered materials. This bit is a general-purpose tool suited for use by aviation maintenance technicians, machinists, and precision tradespeople working with thin-gauge metals, composites, and tight-tolerance assemblies.\u003c\/p\u003e\n\u003cp\u003eThe 11090 is rated to NAS 907 Type B standards, making it appropriate for aerospace and aircraft maintenance environments where controlled hole geometry is critical. The 6-inch overall length provides the extended reach needed when drilling through structural members, panels, or stacked materials where a standard-length bit cannot access the work area. Right-hand cutting direction is standard for conventional drill press and hand-drill operation. General-purpose performance rating makes this bit suitable for a range of metals encountered in aviation and precision fabrication work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire size 60 with a decimal diameter of 0.0400 inches for tight-tolerance precision work\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning for accurate, self-starting hole entry\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with oxide finish for wear resistance in metal drilling\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length for extended-reach drilling in confined or deep-access areas\u003c\/li\u003e\n  \u003cli\u003eNAS 907 Type B rated for aerospace and aircraft maintenance applications\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration with 2-flute spiral design for efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for aircraft maintenance, precision machining, and fabrication operations requiring wire-gauge drill bits conforming to NAS 907 Type B specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists, aviation maintenance technicians, or tradespeople familiar with small-diameter precision drilling. Secure the straight-cylindrical shank firmly in a compatible drill chuck rated for the shank diameter before operation. Use appropriate cutting fluid or lubrication when drilling hard metals to extend bit life and maintain hole tolerance. Inspect the cutting edges before each use — small-diameter bits at this size are susceptible to breakage if side-loaded or run at incorrect speeds.\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: 60\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal)\u003c\/strong\u003e: 0.0400 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: 0.6875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0980 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 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: 11090\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51755197825330,"sku":"11090","price":18.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/127faed2987d64b36e2dec26dd95426b_8aeae5de-73e5-45ce-819d-1b6d0dfe086c.jpg?v=1788952078","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-11090-aircraft-extension-drill-bit-wire-60","provider":"Voomi Supply","version":"1.0","type":"link"}
