Manufactured from solid carbide in the IC908 grade with a PVD-applied TiAlN coating, this insert delivers thermal resistance and edge retention across a wide range of workpiece materials. It carries an ISO 13399 classification and fits the 16IR insert style. The inscribed circle measures 3\/8 inches (0.3750 inches) and insert thickness is 0.143 inches. A 0.003-inch corner radius keeps thread root geometry precise at a 1.50mm pitch.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal threading operations where ISO-standard thread profiles are required. The IC908 grade with PVD TiAlN coating supports universal workpiece material compatibility, covering steel, stainless steel, cast iron, non-ferrous alloys, high-temperature alloys, and hardened materials as reflected by primary workpiece material codes H, K, M, N, P, and S. It is a standard single-insert package item within the ISCARTHREAD series and is ordered in multiples of five.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC908 solid carbide grade with PVD TiAlN coating for extended tool life across varied materials\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting geometry for internal ISO thread profiles at 1.50mm pitch\u003c\/li\u003e\n\u003cli\u003e16IR insert style with 3\/8-inch inscribed circle for compatibility with standard 16IR toolholders\u003c\/li\u003e\n\u003cli\u003e0.003-inch corner radius for accurate thread root form\u003c\/li\u003e\n\u003cli\u003eISO 13399 compliant tooling data for use with CAM and tool management systems\u003c\/li\u003e\n\u003cli\u003eUniversal workpiece material rating covering steel, stainless, cast iron, non-ferrous, and superalloys\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 16IR-style internal threading toolholders within the ISCARTHREAD series.
