It carries the IC1007 manufacturer grade with a PVD-applied TiAlN coating, placing it in the submicron carbide category suited for demanding threading operations. The insert features a 16ER style profile with a 3\/8 inch (9.52 mm) inscribed circle and a corner radius of 0.0070 inch (0.17 mm). Right-hand orientation makes it compatible with standard external threading toolholders. Machinists and CNC operators working in job shops or production environments use this insert for consistent thread form on a broad range of workpiece materials.\u003c\/p\u003e\u003cp\u003eThis insert is intended for external UN-standard threading applications. The IC1007 grade with TiAlN finish is rated for use across universal workpiece material groups, covering common steel, stainless, cast iron, nonferrous, and heat-resistant alloy families as indicated by material codes H, K, M, N, P, and S. It fits into 16ER-profile toolholders used on CNC lathes and turning centers in both production and maintenance threading scenarios. The laydown seating geometry provides stable insert indexing and repeatable thread geometry across multiple cutting edges.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide submicron substrate with IC1007 grade designation\u003c\/li\u003e\n\u003cli\u003ePVD TiAlN coating for wear resistance across multiple workpiece material groups\u003c\/li\u003e\n\u003cli\u003e18 TPI UN external thread form, right-hand cutting orientation\u003c\/li\u003e\n\u003cli\u003e16ER insert style with 3\/8 inch inscribed circle for standard toolholder compatibility\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0070 inch (0.17 mm) for accurate thread root profile\u003c\/li\u003e\n\u003cli\u003eRated for universal material groups: H, K, M, N, P, and S\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 16ER-profile external threading toolholders conforming to ISO 13399 standards.
