It carries the TN60 manufacturer grade and features a TiCN plus NbC coating classification listed as uncoated process, with a positive rake angle of 15 degrees and a honed cutting edge for clean, consistent chip formation. The triangular insert shape provides 3 cutting edges, an inscribed circle of 0.375 inches, and a corner radius of 0.0156 inches (1\/64 inch). It is used in external turning, boring, internal facing, back boring, and copying operations, and is installed by machinists and tooling technicians in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for finishing and semi-finishing passes on steel and stainless steel workpieces, corresponding to ISO material grades P01, P10, and P20. It fits ISOI-series toolholders that accept TPMR-style inserts with a clamp holding method. The ISO designation for this insert is TPMR160304HQ, and the industry standard number is TPMR321HQTN60. Its multi-use design supports a range of turning applications, making it a practical choice for shops that run varied workpiece materials and geometries on the same setup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCermet insert material with TiCN plus NbC coating composition for thermal and wear resistance\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle (15 degrees) with honed cutting edge reduces cutting forces on finishing passes\u003c\/li\u003e\n  \u003cli\u003e3 usable cutting edges on a 60-degree triangular shape maximize insert life per unit\u003c\/li\u003e\n  \u003cli\u003eHQ chip breaker geometry supports back boring, boring, copying, external turning, and internal facing\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.2167 inches supports semi-finishing and finishing stock removal\u003c\/li\u003e\n  \u003cli\u003eCompliant with ANSI and ISO insert standards for reliable toolholder fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for ISOI-series TPMR-style clamp-type toolholders accepting a 3\/8-inch inscribed circle triangular insert.
