The insert features a TiAlN coating applied via PVD process, providing hardness and heat resistance suited for a range of workpiece materials. With a 60-degree included angle, 9.53 mm (3\/8 inch) inscribed circle, and 3.60 mm thickness, the 53688 follows a standard 3JIR style geometry for right-hand internal threading operations. Machinists and CNC programmers working in production or job-shop environments install this insert into compatible toolholders on lathes and turning centers.\u003c\/p\u003e\u003cp\u003eThis insert is intended for right-hand internal UN thread applications at 14 TPI in accordance with ANSI B1.1:74. The SCB chipbreaker geometry and universal material compatibility make it suitable for a broad range of workpiece materials including ferrous and non-ferrous metals and exotic alloys, corresponding to ISO material groups H, K, M, N, P, and S. It is used in single-point threading passes on CNC lathes and manual turning equipment where precise thread form and repeatability are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with TiAlN PVD coating for extended tool life across multiple material groups\u003c\/li\u003e\n\u003cli\u003e3JIR insert style with right-hand cutting orientation for internal UN threading\u003c\/li\u003e\n\u003cli\u003e14 TPI thread pitch conforming to ANSI B1.1:74 standard\u003c\/li\u003e\n\u003cli\u003e60-degree included angle for standard UN thread form\u003c\/li\u003e\n\u003cli\u003eSCB chipbreaker for chip control in through and blind-bore threading\u003c\/li\u003e\n\u003cli\u003eCompatible with ISO material groups H, K, M, N, P, and S (universal workpiece material range)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement threading insert for toolholders accepting the 3JIR insert style with a 3\/8 inch inscribed circle.
