Built from solid carbide and finished with a PVD-applied TiAlN coating, it carries the IC908 manufacturer grade and is engineered for consistent performance across a wide range of workpiece materials. The insert features a 3\/8 inch (0.375 inch decimal) inscribed circle, a 0.143 inch thickness, and a 0.20 mm corner radius. It is used in CNC and manual turning applications where precise internal thread form and tool life are priorities. Licensed ISCARTHREAD series tooling is typically installed by machining professionals in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal UN threading operations on a broad range of materials, including steels, stainless steels, cast irons, non-ferrous metals, high-temperature alloys, and hardened materials, as reflected by its primary workpiece material codes H, K, M, N, P, and S. The 16IR insert style and 16 size code position it for use in standard 16IR boring bar and threading toolholders. It is appropriate for both high-volume production runs and precision single-part work where thread quality and repeatability are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with PVD-applied TiAlN coating for wear resistance\u003c\/li\u003e\n\u003cli\u003eIC908 grade rated for universal workpiece material compatibility\u003c\/li\u003e\n\u003cli\u003eRight-hand internal UN thread form at 8 TPI\u003c\/li\u003e\n\u003cli\u003e3\/8 inch inscribed circle (0.3750 inch decimal) for precise toolholder seating\u003c\/li\u003e\n\u003cli\u003eM chipbreaker geometry for chip control during internal threading\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 13399 tooling data standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 16IR-style internal threading toolholders and boring bars that accept laydown inserts with a 3\/8 inch inscribed circle.

Ensure the machine spindle is fully stopped and the toolholder is secured before seating or replacing the insert. Use the correct torque wrench and insert screw for the toolholder series to avoid cracking the carbide substrate. Verify thread form and pitch with a thread gauge after first-article setup before committing to a production run.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16IR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC908\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C1, C2, C6, C7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 8 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.20 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.143 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN, PVD Process\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ISCARTHREAD\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: 0.1 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: 5902387\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51751382155570,"sku":"5902387","price":150.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eb67fa3ecc20a05c9b2a1018ac227116.jpg?v=1788923130","url":"https:\/\/voomisupply.com\/products\/iscar-5902387-threading-insert-8-tpi-3-8-inch-ic908","provider":"Voomi Supply","version":"1.0","type":"link"}
