Conforming to the DNMG431-M3 industry standard, this insert features a 55-degree diamond shape with a negative rake angle and a 0-degree relief angle. The TP1501 grade substrate is CVD-coated with a TiCN, Al2O3, and Cr Duratomic multilayer coating, optimized for wear resistance and thermal stability during continuous and interrupted cuts in steel and cast iron. With 4 cutting edges per insert and a chamfered and honed cutting edge style, this insert delivers consistent performance across high-volume production runs. It is sold individually but requires a minimum order of 10 pieces.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for medium to roughing steel turning operations in manufacturing and machining environments. Primary workpiece material is steel (ISO material code P), with secondary suitability for cast iron and hard materials (ISO codes K and H). Supported applications include turning, facing, boring, and back turning. The M3 chip breaker geometry is engineered for reliable chip control across a range of depths of cut, making it appropriate for general-purpose turning on CNC lathes in job shop and production settings. Licensed machinists and CNC operators are the typical end users for this insert.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDNMG431-M3 geometry with 55-degree diamond shape and negative rake for stable, high-force cutting\u003c\/li\u003e\n  \u003cli\u003eTP1501 grade with CVD-applied Duratomic TiCN, Al2O3, and Cr multilayer coating for extended tool life in steel\u003c\/li\u003e\n  \u003cli\u003e4 cutting edges per insert for cost-effective tool management in production environments\u003c\/li\u003e\n  \u003cli\u003eM3 chip breaker design for reliable chip control in medium to roughing steel applications\u003c\/li\u003e\n  \u003cli\u003eChamfered and honed cutting edge style for reduced insert breakage and consistent surface finish\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp, pin, and lever lock insert holding methods for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement insert for DNMG toolholders accepting 431-size inserts with clamp, pin, or lever lock holding methods.
