It is manufactured from solid carbide and coated via CVD with a multilayer Duratomic coating of TiCN, Al2O3, and Cr for extended tool life and thermal resistance. The insert features a negative rake angle, a 60-degree included angle, and a chamfered and honed cutting edge style. With six usable cutting edges and an M3 chip breaker geometry, this insert is suited for productive material removal in steel and stainless steel applications. Licensed machinists and CNC operators working in production environments are the primary users.\u003c\/p\u003e\u003cp\u003eThis insert is primarily rated for steel (ISO material code P) at material grades P10, P20, P30, and P35, with secondary suitability for stainless steel (code M) and cast iron (code K). The M3 chip breaker geometry supports a broad range of depths of cut up to 0.6102 inches, making it appropriate for medium to roughing passes. It is compatible with insert holding systems using clamp, pin, or lever lock toolholders designed for TNMG-style inserts. The ANSI industry standard number is TNMG331-M3 and the ISO equivalent code is TNMG160404-M3.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD Duratomic multilayer coating (TiCN, Al2O3, Cr) for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eSix cutting edges per insert for extended per-unit value in production runs\u003c\/li\u003e\n\u003cli\u003eM3 chip breaker geometry supports turning, facing, boring, and back turning\u003c\/li\u003e\n\u003cli\u003eChamfered and honed cutting edge style reduces chipping at entry\u003c\/li\u003e\n\u003cli\u003eNegative rake, 0-degree relief angle (clearance code N) for rigid, stable cutting\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and ISO dimensional standards; ISO code TNMG160404-M3\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in TNMG-style toolholders that accept clamp, pin, or lever lock holding methods.
