It carries the CPMT21.51-F1 industry standard designation and is manufactured to TP25 grade with a multilayer CVD coating of TiCN, Al2O3, and Cr for extended tool life and heat resistance. The insert features an 80-degree diamond shape, a neutral hand orientation, and a sharp cutting edge style with an F1 chip breaker geometry. With a 0.2539-inch insert length and a 0.0157-inch corner radius, it delivers controlled chip formation across a range of material removal applications. Licensed machinists and tooling professionals install this insert in standard CPMT-compatible toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for boring, facing, and turning operations on steel, stainless steel, and cast iron workpieces. The TP25 grade with CVD multilayer coating targets ISO material groups P, M, and K, corresponding to material grades P20, P30, and P35. It is a productive choice in production turning environments where consistent chip control and wear resistance are required across moderate to high cutting speeds. Two cutting edges per insert extend service life before replacement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTP25 grade solid carbide with multilayer CVD coating: TiCN, Al2O3, and Cr for wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape with sharp cutting edge for clean entry and low cutting forces\u003c\/li\u003e\n  \u003cli\u003eF1 chip breaker geometry for controlled chip formation in steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation compatible with standard CPMT screw-lock toolholders\u003c\/li\u003e\n  \u003cli\u003eTwo usable cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003eRated for boring, facing, and turning multi-use applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement insert for CPMT-series screw-lock toolholders conforming to ANSI and ISO standards.
