Carrying manufacturer grade TP2501, it is designed for external turning operations including back turning, facing, profiling, and general turning. The insert features a 35-degree diamond shape, a neutral hand orientation, and a chamfered and honed cutting edge for controlled chip formation. With four usable cutting edges and an M3 chip breaker geometry, this insert delivers consistent performance on steel and stainless steel in production machining environments. It is installed by machinists and CNC toolroom technicians on lathes and turning centers.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning steel (ISO material code P), stainless steel (M), and cast iron (K). It fits within the VNMG-M3 series toolholder system and is appropriate for roughing, semi-finishing, and finishing passes where the M3 chip breaker geometry is specified. Typical applications include shaft work, facing operations, and contour profiling on both manual and CNC turning equipment. Material grades P10, P20, P30, and P35 are supported. The insert conforms to both ANSI and ISO standards, with ISO code VNMG160404-M3 and industry standard number VNMG331-M3.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD Duratomic multilayer coating: TiCN, Al2O3, Cr for extended tool life on steel and stainless\u003c\/li\u003e\n  \u003cli\u003e35-degree diamond insert shape with 4 cutting edges for maximum index value\u003c\/li\u003e\n  \u003cli\u003eM3 chip breaker geometry supports back turning, facing, profiling, and turning\u003c\/li\u003e\n  \u003cli\u003eChamfered and honed cutting edge reduces chipping on interrupted cuts\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp, pin, and lever lock holding methods\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO standards; ISO code VNMG160404-M3\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in VNMG-series toolholders that accept a 35-degree diamond insert with a 3\/8-inch inscribed circle, M tolerance, N clearance, and clamp, pin, or lever lock holding.
