It carries the industry standard designation DNMU333-M3 and manufacturer grade TP1501, featuring a CVD-applied Duratomic coating of TiCN, Al2O3, and Cr for extended tool life and thermal resistance. The insert has a 55-degree diamond shape, a 3\/8-inch inscribed circle (0.3750 inches), a 0.0472-inch corner radius (3\/64 inch), and an overall length of 0.9134 inches. With four cutting edges and a negative rake geometry, it delivers consistent performance in steel and cast iron applications where tool economy and surface finish are critical.\u003c\/p\u003e\u003cp\u003eThis insert is suited for use on CNC lathes and turning centers in both production and job-shop environments. It supports back turning, boring, facing, and standard OD turning operations. The neutral hand orientation makes it adaptable across a wide range of setups. Primary workpiece material is steel (ISO P code), with secondary suitability for cast iron and hard materials (ISO K and H codes). Material grades P10 and P20 apply, making it appropriate for light to medium roughing and finishing cuts. The M3 chip breaker geometry is optimized for controlled chip formation during interrupted and continuous cuts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD Duratomic coating (TiCN, Al2O3, Cr) for thermal stability and wear resistance in steel and cast iron cutting\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape with four usable cutting edges for cost efficiency\u003c\/li\u003e\n\u003cli\u003eM3 chip breaker with chamfered and honed cutting edge style for reliable chip control\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation supports flexible setup on standard turning and boring operations\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut up to 0.4094 inches suitable for medium-stock roughing passes\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp, pin, and lever-lock insert holding methods\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct application insert for toolholders accepting DNMU-style inserts with a 55-degree diamond shape, 3\/8-inch inscribed circle, and clamp, pin, or lever-lock holding methods per ANSI and ISO standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machining professionals or CNC setup technicians.
