This indexable carbide insert features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal protection during high-speed steel cutting. The insert carries a 0.40 mm corner radius, a 55-degree diamond shape, and a neutral hand orientation. With four cutting edges per insert, it delivers consistent performance across multiple index positions. Installed by machinists and CNC operators in production turning environments, it fits standard DNMG toolholders using clamp or screw holding methods.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered primarily for turning steel (ISO material group P) and cast iron (ISO material group K) in medium to finish machining applications. The PM chip breaker geometry is suited for stable, continuous cuts where chip control and surface finish are priorities. The T-Max P series is a standard Sandvik Coromant platform widely used in production shops running general-purpose turning operations on ferrous workpiece materials. It is sold individually but subject to a minimum order quantity of 10 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for wear resistance on steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape with four indexable cutting edges\u003c\/li\u003e\n  \u003cli\u003e0.40 mm (0.0156 inch) corner radius for medium to finish turning passes\u003c\/li\u003e\n  \u003cli\u003ePM chip breaker geometry for controlled chip formation in continuous cuts\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation compatible with standard DNMG clamp and screw toolholders\u003c\/li\u003e\n  \u003cli\u003eISO code DNMG 15 04 04-PM 4425 for cross-reference with toolholder catalogs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard DNMG-style toolholders accepting a 1\/2 inch (12.70 mm) inscribed circle insert.
