Built from submicron-grade solid carbide with a PVD-applied TiAlN coating, the IC908 grade delivers wear resistance and edge integrity across a broad range of workpiece materials. The insert cuts right-hand external NPT threads at 18 threads per inch (TPI) with a 3\/8-inch inscribed circle and a 0.002-inch corner radius. It is designed for machinists and toolroom operators running production or job-shop threading operations where consistent thread form and insert life are critical.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external NPT pipe thread applications in both production and maintenance machining environments. The universal primary workpiece material classification means it performs across steel, stainless, cast iron, non-ferrous alloys, and high-temperature alloys. Typical use cases include threading hydraulic fittings, pipe nipples, and fluid-system components where NPT sealing-thread accuracy is required. The insert seats in the laydown orientation within compatible 16ER-series toolholders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC908 submicron solid carbide grade with PVD TiAlN coating for extended tool life\u003c\/li\u003e\n\u003cli\u003e18 TPI NPT thread form, right-hand external cut\u003c\/li\u003e\n\u003cli\u003e3\/8-inch (9.52 mm) inscribed circle for use in 16ER-series toolholders\u003c\/li\u003e\n\u003cli\u003e0.002-inch corner radius for accurate NPT thread-form geometry\u003c\/li\u003e\n\u003cli\u003eUniversal material grade compatibility: steel, stainless, cast iron, non-ferrous, and high-temperature alloys\u003c\/li\u003e\n\u003cli\u003eCompliant with ISO 13399 cutting tool data standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 16ER-series laydown threading toolholders.

Power down and lock out the machine before indexing or replacing inserts. Use the correct torque wrench and seating screw specified by the toolholder manufacturer — do not overtighten the clamping screw. Verify insert seating and thread-form accuracy with a calibrated NPT thread gauge before running production parts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16ER Laydown\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 18 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches \/ 9.52 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.002 inches (0.06 mm)\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: TiAlN, PVD Applied\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (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\u003ePackage Quantity\u003c\/strong\u003e: 1 insert\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.079 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: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5902115\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51735219831090,"sku":"5902115","price":178.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/353f4ed8758adf97cfbaaf9e6d5ecba6.jpg?v=1788770480","url":"https:\/\/voomisupply.com\/products\/iscar-5902115-threading-insert-18-tpi-npt-ic908-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
