It features a CVD multilayer coating of TiCN, Al2O3, and Cr, delivering balanced wear resistance and toughness suited to steel, stainless steel, and cast iron workpieces. The triangular insert shape provides three cutting edges with a positive rake angle of 17 degrees and a relief angle of 11 degrees. With a corner radius of 0.0158 inches and an F1 chip breaker geometry, it is optimized for finishing operations requiring sharp, controlled cuts and smooth surface finishes.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for finishing passes in back turning, boring, facing, and general turning applications on steel (P-class), stainless steel (M-class), and cast iron (K-class) workpieces. Material grade designations P20, P30, and P35 indicate suitability for moderate to higher-toughness steel cutting conditions. The neutral hand orientation makes it compatible with standard TPMR-style insert pockets on a wide range of tool holders used in both production and maintenance machining environments. It is installed by machinists and tooling specialists in job shop, production, and maintenance machining settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and Cr for extended tool life on steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eF1 chip breaker geometry optimized for finishing operations with sharp cutting edge style\u003c\/li\u003e\n  \u003cli\u003eThree cutting edges per insert — ANSI code TPMR321, ISO code TPMR160304\u003c\/li\u003e\n  \u003cli\u003ePositive rake and positive side clearance for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation fits standard TPMR clamp-style tool holders\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut up to 0.611 inches in applicable finishing conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit insert for TPMR-series clamp-style turning tool holders conforming to ANSI and ISO standards.
