Built from solid carbide and CVD-coated with a TiCN, Al2O3, and TiN multilayer stack, this insert delivers high wear resistance across a range of steel cutting conditions. The 55-degree diamond (rhombic) shape provides a strong, versatile cutting geometry, while the PF chip breaker is optimized for finishing passes. With a 0.5 inch inscribed circle and a 1.19 mm (0.0469 inch) corner radius, the insert fits standard DNMG-style toolholders using clamp or screw holding methods. Machinists and CNC turning specialists running steel finishing operations will find this insert suited to applications where consistent surface finish and dimensional accuracy are the priority.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for turning applications on steel materials, corresponding to ISO material group P. The 4425 grade is characterized by high wear resistance to moderate wear resistance and toughness, making it appropriate for continuous to light interrupted cuts on steel. The PF chip breaker geometry is purpose-built for finishing operations where chip control and surface quality are critical. The neutral hand orientation allows flexible deployment in a range of turning setups. This insert is part of the SANDVIK COROMANT T-Max P series, a product line engineered for external and internal turning in production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for high wear resistance on steel\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond (rhombic) insert shape for versatile turning geometry\u003c\/li\u003e\n  \u003cli\u003ePF chip breaker optimized for finishing operations and controlled chip formation\u003c\/li\u003e\n  \u003cli\u003e1.19 mm (0.0469 inch) corner radius for consistent surface finish\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation compatible with standard DNMG clamp and screw toolholders\u003c\/li\u003e\n  \u003cli\u003ePart of the T-Max P series targeting steel turning applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement insert for DNMG-style toolholders accepting a 0.5 inch inscribed circle, 3\/16 inch thick negative-rake inserts with clamp or screw holding.
