It is manufactured from solid carbide in the IC908 submicron grade and finished with a PVD-applied TiN\/TiAlN coating for improved wear resistance and edge integrity. The insert follows the 16ER style designation and carries an inscribed circle of 0.375 inches (9.53 mm) with a thickness of 0.143 inches. It is right-hand oriented and intended for use by machinists and CNC turning professionals on threading operations where UNJ profile tolerances are required.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external threading applications on CNC lathes and turning centers in production and job-shop environments. The IC908 grade with PVD coating performs across a broad range of workpiece materials, including steel, stainless steel, cast iron, non-ferrous metals, and high-temperature alloys, as reflected by its universal primary workpiece material classification. It is a direct fit for ISCARTHREAD series toolholders accepting 16ER inserts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e16ER insert style with 24 TPI for UNJ external thread profile\u003c\/li\u003e\n\u003cli\u003eIC908 submicron solid carbide grade with PVD TiN\/TiAlN coating for extended tool life\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation for standard external threading setups\u003c\/li\u003e\n\u003cli\u003e0.375-inch inscribed circle with 0.143-inch thickness for precise seating in compatible holders\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.006 inches (0.15 mm) for accurate thread form geometry\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 with ISCARTHREAD series toolholders that accept 16ER style laydown threading inserts.
