Built from solid carbide and coated with a CVD-applied TiCN, Al2O3, and TiN multilayer stack, this insert delivers wear resistance and thermal stability during continuous and interrupted cuts. The diamond-shaped insert body features a 55-degree included angle, a 0.79 mm corner radius, and four usable cutting edges. The PM chip breaker geometry is optimized for productive turning in steel and cast iron. Installed by machinists and CNC operators in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for turning operations on steel as its primary workpiece material and cast iron as a secondary material. It fits standard DNMG-style toolholders that accept a 3\/8-inch inscribed circle insert with clamp or screw holding. The T-Max P series designation indicates compatibility with SANDVIK COROMANT T-Max P toolholder systems. The neutral hand orientation makes it suitable for both right-hand and left-hand cutting directions depending on toolholder configuration. Typical applications include external turning, facing, and profiling passes in medium to high production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD-applied TiCN, Al2O3, and TiN multilayer coating for extended tool life in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape (Shape Code D) with four cutting edges for cost-per-edge efficiency\u003c\/li\u003e\n  \u003cli\u003e0.79 mm corner radius for a balance of edge strength and surface finish capability\u003c\/li\u003e\n  \u003cli\u003ePM chip breaker geometry suited for steel turning with controlled chip formation\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation compatible with multiple toolholder setups\u003c\/li\u003e\n  \u003cli\u003eClamp and screw insert holding method for secure seating under load\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in DNMG-style toolholders within the SANDVIK COROMANT T-Max P series.
