Built to Series 906 standards and compliant with NAS 907 Type B, this bit features a 135-degree split point angle with web thinning for reduced thrust and improved self-starting performance. The spiral flute geometry and oxide finish make it well suited for ferrous metals and tough alloys where clean, accurate holes are required. Licensed tradespeople and aerospace maintenance technicians working on structural and sheet metal assemblies will find this bit a reliable production tool.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is used in applications requiring extended reach and tight-tolerance hole making in metal substrates. The 0.055-inch diameter corresponds to wire gauge size 54, a common specification in aircraft structural drilling, instrument panel fabrication, and precision sheet metal work. The straight-cylindrical shank provides secure chuck engagement in standard drill chucks and pneumatic drills used in both shop and field service environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire size 54 (0.055 inches) diameter with tight tolerance of +0.0000 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e135-degree standard point angle with web-thinned tapered web for reduced entry force\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across ferrous and general-purpose materials\u003c\/li\u003e\n  \u003cli\u003eOxide finish provides basic lubricity and corrosion resistance during storage and use\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with 2-flute configuration for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCompliant with NAS 907 Type B standard for aircraft-grade drilling applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and general-purpose aircraft extension drill bit for use with standard straight-shank drill chucks in keyed, keyless, and pneumatic configurations compatible with 0.055-inch shank diameters.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this drill bit is typically performed by machinists, aerospace maintenance technicians, or sheet metal workers. Ensure the drill chuck is fully tightened and the workpiece is properly secured before drilling. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and maintain hole tolerance. Inspect the bit for wear or chipping before each use, particularly when working to tight diameter tolerances.\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: 54\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.055 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: 0.875 inches (7\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.055 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\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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: 11084\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51732046807346,"sku":"11084","price":16.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/127faed2987d64b36e2dec26dd95426b_c9cffa03-b4cb-4189-86c1-1791569d8d3f.jpg?v=1788738627","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-11084-aircraft-extension-drill-bit-0-055-in","provider":"Voomi Supply","version":"1.0","type":"link"}
