Built to Series 906 specifications, it features a 135-degree split point that is self-centering and web-thinned, reducing walking and thrust on entry. The straight-cylindrical shank measures 0.191 inches in diameter, matching the wire gauge No. 11 drill size, and the spiral flute length runs 2.3125 inches. Right-hand cutting direction and a tapered web configuration suit general-purpose production and maintenance drilling tasks. Licensed HVAC, mechanical, and aircraft maintenance technicians working on sheet metal and structural assemblies will find this drill well suited for extended-reach access holes.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for applications where standard-length bits cannot reach, such as drilling through flanged assemblies, deep cavities, or obstructed sheet metal sections. The oxide finish provides baseline lubricity and corrosion resistance for dry or lightly lubricated cutting operations. With an overall length of 6 inches and a wire gauge No. 11 diameter of 0.191 inches, it fits common requirements in HVAC sheet metal fabrication, aircraft maintenance, and general metal fabrication shops.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point for self-centering entry with reduced thrust\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web construction minimizes walking on hard or thin material\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for durability across steel, aluminum, and similar metals\u003c\/li\u003e\n\u003cli\u003eOxide finish for basic lubricity and corrosion protection in dry-cut applications\u003c\/li\u003e\n\u003cli\u003e6-inch overall length provides extended reach into deep or obstructed workpieces\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 Type B standards for aircraft and structural drilling applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use aircraft extension drill for applications requiring a wire gauge No. 11 (0.191 inch) diameter bit with a straight-cylindrical shank and 135-degree split point geometry, conforming to NAS 907 Type B.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis drill bit is installed by machinists, aircraft maintenance technicians, and sheet metal tradespeople using standard drill chucks compatible with a straight-cylindrical shank. Always power down or de-energize all equipment in the work area before drilling near electrical components, and follow applicable shop safety and workholding procedures. Use appropriate cutting fluid or lubricant for the base material to extend bit life and maintain hole tolerance. Inspect the cutting edges before each use and replace if chipping or wear is observed to stay within the stated diameter tolerance of +0.0000 to -0.0007 inches.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.191 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: 2.3125 inches (2-5\/16 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: 0.191 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\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\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 -0.0007 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: 906\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: NAS 907 Type B\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 11041\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51751650099506,"sku":"11041","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/127faed2987d64b36e2dec26dd95426b_03052c43-652d-41d0-b496-af9c66c5d974.jpg?v=1788924027","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-11041-aircraft-extension-drill-bit-no-11","provider":"Voomi Supply","version":"1.0","type":"link"}
