It features a 55-degree diamond insert shape (Shape Code D) with a 0.5000-inch inscribed circle and a 0.79 mm (0.0313 inch) corner radius. The insert is manufactured from solid carbide substrate and carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN under manufacturer grade 4415. The PM chip breaker geometry is engineered for controlled chip formation during medium to roughing passes. Licensed machinists and CNC turning specialists install this insert as part of the T-Max P series tooling system.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning steel and cast iron workpieces in both production and job-shop environments. Primary workpiece material is steel (ISO code P); secondary application is cast iron (ISO code K). The neutral hand orientation allows use on standard right-hand turning setups. The insert is held in the toolholder via clamp and screw method, making it compatible with standard DNMG-style toolholders used in production turning cells. Typical applications include roughing and semi-finish turning of carbon steel shafts, cast iron housings, and similar machined components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: TiCN, Al2O3, TiN for wear and heat resistance on steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape with neutral hand for versatile turning setups\u003c\/li\u003e\n  \u003cli\u003ePM chip breaker geometry for reliable chip control in medium to rough turning passes\u003c\/li\u003e\n  \u003cli\u003e0.79 mm corner radius balances surface finish quality with edge strength\u003c\/li\u003e\n  \u003cli\u003e4 cutting edges per insert for extended tooling value across multiple setups\u003c\/li\u003e\n  \u003cli\u003eClamp and screw holding method compatible with standard DNMG-style toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in DNMG-style turning toolholders within the T-Max P series system.
