This indexable insert is manufactured from solid carbide with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, delivering wear resistance and thermal stability across a range of cutting conditions. The 80-degree diamond insert shape (Shape Code C) provides two strong cutting edges per corner, and with 4 cutting edges total, the insert offers extended tool life per unit. It carries a neutral hand orientation and fits standard CNMG-style toolholders. Machinists and CNC operators in production and job-shop environments install this insert for turning steel and cast iron workpieces.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning steel (ISO material code P) as its primary workpiece material, with cast iron (ISO material code K) as a secondary application. The PM chip breaker geometry is optimized for medium to roughing passes on steel components, helping manage chip formation and cutting forces. The T-Max P series designation indicates compatibility with SANDVIK COROMANT T-Max P toolholder systems. Typical applications include shaft turning, facing, and profiling on horizontal and vertical CNC turning machines in both production and maintenance machining environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for wear and crater resistance\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape with 4 cutting edges for cost-effective indexing\u003c\/li\u003e\n  \u003cli\u003ePM chip breaker geometry optimized for steel turning with controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation compatible with standard CNMG clamp and screw holding methods\u003c\/li\u003e\n  \u003cli\u003eISO code CNMG 12 04 16-PM 4425 for direct cross-reference and toolholder selection\u003c\/li\u003e\n  \u003cli\u003eManufacturer grade 4425 carbide substrate balances toughness and hardness for interrupted and continuous cuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNMG-style toolholders using clamp or screw insert holding methods within the SANDVIK COROMANT T-Max P series.
