It features a CVD-applied triple-layer coating of TiCN, Al2O3, and TiCN, which provides wear resistance and thermal stability during continuous and interrupted cuts. The insert carries an 80-degree diamond shape, a neutral hand orientation, and a 0.8 mm corner radius. With four usable cutting edges and the RM5 chip breaker geometry, it delivers controlled chip formation across a broad range of depths of cut up to 12.90 mm. This insert is intended for use by machinists and tooling professionals in production turning environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered primarily for steel and stainless steel workpieces, corresponding to ISO material codes P and M, with secondary suitability for super-alloys and titanium (ISO code S). It is applicable across turning, facing, and boring operations, making it a versatile option for shops running mixed production. The RM5 chip breaker geometry suits medium-duty cutting conditions where chip control and surface finish consistency are priorities. The WMP20S grade sits within material grade designations M20, P25, and S20, covering a useful range of feeds and speeds in general-purpose turning.\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 applications\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (shape code C) with chamfered and honed cutting edge style\u003c\/li\u003e\n  \u003cli\u003eRM5 chip breaker geometry supports turning, facing, and boring with controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert maximize cost-per-edge value\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation fits standard CNMG toolholders without left- or right-hand restriction\u003c\/li\u003e\n  \u003cli\u003eCompatible with both clamp and pin insert-holding methods\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNMG-style indexable turning toolholders that accept a 432 insert size (0.5000 inch inscribed circle, 3\/16 inch thickness).
