The insert features a triple-layer CVD coating  -  TiCN, Al2O3, and TiCN  -  applied through a chemical vapor deposition process that delivers superior wear resistance and thermal stability. The 80-degree diamond insert shape provides a strong cutting edge geometry suitable for continuous and interrupted cuts. With a 0.5-inch inscribed circle, a thickness of 0.1875 inches, and a corner radius of 0.0157 inches, this insert is built for precision finishing and semi-finishing operations across a range of workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered for turning, facing, and boring applications in steel and stainless steel as its primary workpiece materials, with secondary capability in super-alloys and titanium. The MM5 chip breaker geometry and chamfered-and-honed cutting edge style are optimized for ISO material groups P and M, with S20 capability for demanding alloy applications. It carries a neutral hand designation, making it suitable for standard right-hand toolholders. The insert is held by clamp or pin methods and conforms to ANSI and ISO standards. ISO code reference is CNMG120404-MM5 WMP20S.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD triple-layer coating (TiCN \/ Al2O3 \/ TiCN) for extended tool life in steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eMM5 chip breaker geometry with chamfered and honed cutting edge for controlled chip formation\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (CNMG style) with 4 usable cutting edges\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin insert holding methods\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation for broad toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO standards; ISO designation CNMG120404-MM5 WMP20S\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard CNMG-style toolholders that accept a 0.5-inch inscribed circle, 80-degree diamond insert with clamp or pin retention.
