Built from high-speed steel with an oxide finish, this bit carries a 135-degree split point that self-centers on contact, reducing walking and the need for a center punch. The straight cylindrical shank measures 0.1850 inches in diameter and the overall length reaches 6 inches, giving technicians extended reach in tight or deep-cavity work. Web thinning reduces thrust and cutting resistance, making it well suited for hand-held or drill press work where clean entry holes are required.\u003c\/p\u003e\u003cp\u003eThis bit is intended for use in applications that demand extended reach beyond what a standard-length drill bit provides, including aircraft sheet metal work, structural assembly, and general fabrication. Its 6-inch overall length and 2.3125-inch flute length make it practical for drilling through stacked materials or accessing recessed surfaces. It is typically installed and used by aircraft maintenance technicians, sheet metal fabricators, and machining professionals working to NAS 907 Type B standards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire size 13 (0.1850 inches) with tight diameter tolerance of +0.0000 to -0.0007 inches\u003c\/li\u003e\n\u003cli\u003e135-degree split point with self-centering geometry reduces drill walking\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces cutting thrust and extends bit life\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with oxide finish for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003e6-inch overall length provides extended reach for deep or restricted work areas\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with 2-flute configuration for efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose aircraft extension drill bit conforming to NAS 907 Type B standards, suitable for use in drill presses, hand drills, and pneumatic drilling equipment that accept a 0.1850-inch straight cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit should be installed and operated by qualified technicians familiar with metal drilling procedures. Secure the straight cylindrical shank firmly in the drill chuck before use, and verify chuck runout is within acceptable limits for precision work. Use appropriate cutting fluid or lubricant when drilling harder alloys to extend bit life. Follow applicable workplace safety standards and wear appropriate eye protection during all drilling operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1850 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\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\u003eSelf-Centering\u003c\/strong\u003e: Yes\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1850 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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0007 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\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 11043\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51727253504306,"sku":"11043","price":78.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/127faed2987d64b36e2dec26dd95426b_657ce287-3c6b-4d29-922b-4b3e8b8996e6.jpg?v=1788675470","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-11043-aircraft-extension-drill-bit-13-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
