The insert features a 55-degree diamond shape with a negative rake angle, 4 cutting edges, and an M3 chip breaker geometry with a chamfered and honed cutting edge style. It carries a 1\/2-inch inscribed circle diameter, a 3\/16-inch thickness, and a 1\/32-inch corner radius. Designed for precision metal turning operations, this insert suits licensed machinists and tooling specialists working in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for back turning, boring, facing, and general turning applications on steel (ISO material code P), stainless steel (M), and cast iron (K). It carries material grade ratings of P10, P20, P30, and P35, making it a versatile choice across roughing and semi-finishing passes. The DNMG-M3 series geometry targets moderate to heavier chip loads in steel and stainless applications where reliable chip control and edge durability are priorities. It conforms to both ANSI and ISO standards and carries the ISO code DNMG150408-M3. It is sold individually with a minimum order quantity of 10 inserts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD Duratomic multilayer coating (TiCN, Al2O3, Cr) in TP2501 grade for extended tool life in steel cutting\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape with negative rake and N clearance for rigid, secure seating\u003c\/li\u003e\n  \u003cli\u003eM3 chip breaker geometry with chamfered and honed edge for controlled chip formation across P, M, and K materials\u003c\/li\u003e\n  \u003cli\u003e4 indexable cutting edges with clamp, pin, and lever-lock holding compatibility\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.5787 inches with a 1\/32-inch corner radius for precise finish control\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO standards; ISO code DNMG150408-M3\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with DNMG-series toolholders accepting clamp, pin, and lever-lock insert holding methods.
