Built from solid submicron carbide and coated with a TiN\/TiAlN finish via PVD process, this insert operates in the IC908 manufacturer grade — a wear-resistant grade suited for a broad range of workpiece materials. The insert follows the 11IR style designation, indicating a right-hand internal threading geometry. It has an inscribed circle of 0.250 inches (6.35 mm), a thickness of 0.126 inches, and a corner radius of 0.002 inches (0.05 mm). It is part of the ISCARTHREAD series and conforms to ISO 13399 standards.\u003c\/p\u003e\u003cp\u003eThis insert is intended for internal UN thread cutting at 20 threads per inch. It is used in CNC turning centers and manual lathes wherever right-hand internal UN threads are required. The IC908 grade and PVD TiN\/TiAlN coating make it suitable for universal workpiece material applications, covering ISO material codes H, K, M, N, P, and S — spanning steels, stainless steels, cast irons, non-ferrous metals, high-temperature alloys, and hardened materials. It is installed in a compatible ISCARTHREAD 11IR toolholder by machinists and CNC operators in production and job-shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC908 submicron solid carbide grade with PVD TiN\/TiAlN coating for extended tool life across varied materials\u003c\/li\u003e\n\u003cli\u003eRight-hand internal threading geometry in the 11IR style for UN thread forms\u003c\/li\u003e\n\u003cli\u003e20 TPI cutting profile for standard UN fastener thread applications\u003c\/li\u003e\n\u003cli\u003e0.250-inch inscribed circle with a tight 0.002-inch corner radius for precise thread form accuracy\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 13399 for standardized tooling data and insert identification\u003c\/li\u003e\n\u003cli\u003eUniversal material compatibility across ISO codes H, K, M, N, P, and S\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in ISCARTHREAD series toolholders that accept 11IR-style laydown threading inserts.

Use the correct torque wrench and ISCAR-specified clamping screw when seating the insert to avoid insert rocking or microchipping of the cutting edge. Verify thread pitch and insert style designation against the toolholder specification before cutting. Machinists should confirm proper coolant delivery to the cutting zone when working with high-temperature alloys in the S material group.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 11IR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC908\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN\/TiAlN (PVD Coated)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.250 inches (6.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.126 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.002 inches (0.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: H, K, M, N, P, S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5902165\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51744529154354,"sku":"5902165","price":178.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a8936bbef9e0b925a1615ab54eb9e01.jpg?v=1788857587","url":"https:\/\/voomisupply.com\/products\/iscar-5902165-threading-insert-20-tpi-un-ic908-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
