It carries the TN60 manufacturer grade with a TiCN plus NbC coating classification noted as uncoated in process, featuring a positive rake angle of 14 degrees and a honed cutting edge for consistent, controlled chip formation. The triangular insert shape provides three usable cutting edges, and the 1\/64-inch corner radius supports fine finishing passes on steel and stainless steel workpieces. This insert is held by clamp-style toolholders and suits machinists and CNC operators working in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThe TSJ02820 is rated for external turning, boring, back boring, internal facing, and copying operations. Its primary workpiece material is steel, with secondary suitability for stainless steel, making it a practical choice for general-purpose turning in both production and maintenance machining. The insert conforms to ANSI and ISO standards and carries ISO code TPGR160304R-B with industry standard number TPGR321RBTN60. It is suited to light-to-moderate material removal rates in the P01, P10, and P20 material grade range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCermet insert material with TiCN plus NbC coating for wear resistance on steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eTriangular shape with three cutting edges maximizes usable insert life\u003c\/li\u003e\n  \u003cli\u003ePositive 14-degree rake angle reduces cutting forces and heat generation\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style for consistent surface finish on finishing and semi-finishing passes\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp-style TPGR toolholders per ANSI and ISO standards\u003c\/li\u003e\n  \u003cli\u003eSuitable for external turning, boring, back boring, internal facing, and copying operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in clamp-style TPGR-series indexable toolholders conforming to ANSI and ISO ISOI series standards.
