It features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal protection across a range of cutting conditions. The insert carries a 55-degree diamond shape (ISO shape code D), a neutral hand orientation, and a PM chip breaker geometry engineered for stable chip control during medium to roughing passes. With four usable cutting edges per insert, it delivers a low per-edge cost in production turning environments. Machining professionals and CNC operators working in job shops and production facilities are the primary users of this insert.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning steel and cast iron workpieces in both residential-scale job shops and high-volume production floors. It belongs to the SANDVIK COROMANT T-Max P series, which targets ISO P (steel) and ISO K (cast iron) material groups. Typical applications include external longitudinal turning, facing, and contour operations where consistent chip breaking and edge life are critical to cycle time and surface finish. The PM chip breaker geometry handles a range of depths of cut and feed rates common in medium-duty turning.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for thermal and abrasion resistance\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape with neutral hand orientation for versatile toolpath use\u003c\/li\u003e\n\u003cli\u003ePM chip breaker geometry for reliable chip control in medium to roughing turning passes\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert for extended tool life and reduced cost per edge\u003c\/li\u003e\n\u003cli\u003eISO insert code DNMG 15 04 12-PM 4425 for straightforward catalog cross-reference\u003c\/li\u003e\n\u003cli\u003ePrimary workpiece materials: steel (ISO P) and cast iron (ISO K)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement turning insert for SANDVIK COROMANT T-Max P series toolholders accepting DNMG 15 04 insert seats with clamp and screw holding methods.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInsert seating and indexing should be performed by a qualified CNC machinist or toolroom technician with the machine in a locked-out, zero-energy state per applicable lockout\/tagout procedures.
