Manufactured to a VCB grade with a TiAlN PVD coating, this insert offers broad material compatibility and consistent thread form across a wide range of workpiece materials. The 3JIR insert style features a 60-degree included angle and an SCB chipbreaker suited for standard threading operations. With a 3\/8-inch inscribed circle, the 53588 fits standard toolholders used in CNC and manual lathes for internal threading. Manufactured under ISO 9001:2008 quality standards, it is a reliable choice for machinists and tooling professionals requiring repeatable UN thread production.\u003c\/p\u003e\u003cp\u003eThis insert is applied in internal threading operations on components requiring Unified National (UN) thread forms. The 12 TPI pitch and 3\/8-inch inscribed circle make it appropriate for mid-size bore threading in both production and job-shop environments. Compatible workpiece materials span a wide range, including cast iron, non-ferrous alloys, carbon and alloy steels, stainless steels, heat-resistant superalloys, and hardened materials, as reflected by the primary workpiece material codes H, K, M, N, P, and S. Machinists in metalworking, aerospace component manufacturing, and general machining operations will find this insert suited to their standard threading requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with TiAlN PVD coating for wear resistance across universal workpiece materials\u003c\/li\u003e\n\u003cli\u003eRight-hand internal UN thread form with 60-degree included angle and 12 TPI\u003c\/li\u003e\n\u003cli\u003e3\/8-inch inscribed circle for compatibility with standard 3IR toolholders\u003c\/li\u003e\n\u003cli\u003eSCB chipbreaker geometry for controlled chip evacuation in internal bores\u003c\/li\u003e\n\u003cli\u003eVCB manufacturer grade optimized for standard series threading applications\u003c\/li\u003e\n\u003cli\u003eManufactured under ISO 9001:2008 certified quality processes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement threading insert for standard 3IR internal toolholders used in UN thread cutting applications.
