The insert features a CVD-applied Duratomic multilayer coating of TiCN, Al2O3, and Cr for high wear resistance and thermal stability. The 80-degree diamond shape provides a rigid cutting geometry with a negative rake angle of 18 degrees and a chamfered and honed cutting edge, making it well suited to interrupted and continuous cuts on difficult materials. Four usable cutting edges maximize tool life per insert, and the M3 chip breaker geometry controls chip flow during moderate to heavy feeds.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for boring, facing, and turning operations on stainless steel as the primary workpiece material, with steel as a secondary application. It is compatible with toolholders that accept CNMG-style inserts using clamp, pin, or lever lock holding methods. The neutral hand orientation allows use in both right- and left-hand toolholder configurations. Typical users include CNC machinists and turning-center operators in production and job-shop environments working in material grade classifications M25, M30, and M35 per ISO coding.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD Duratomic multilayer coating (TiCN, Al2O3, Cr) for wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (Shape Code C) with negative rake for strong cutting edge\u003c\/li\u003e\n  \u003cli\u003eM3 chip breaker geometry optimized for medium to heavy feeds on stainless and steel\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert for extended usable tool life\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp, pin, and lever lock CNMG toolholder systems\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards; ISO code CNMG160612-M3\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for CNMG-style toolholders accepting a 5\/8-inch inscribed circle insert with a 1\/4-inch hole diameter and 1\/4-inch insert thickness, using clamp, pin, or lever lock holding methods.
