It carries a manufacturer grade of 4340 and features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability across a broad range of cutting conditions. The insert measures 9.5 mm wide and 4.45 mm thick, with a corner radius of 0.80 mm. It seats in screw-lock toolholders and delivers four usable cutting edges per insert. This part is used by machinists and tooling technicians in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for milling steel, stainless steel, and cast iron workpieces, corresponding to ISO material groups P, M, and K. It fits the N331.1A insert style and is compatible with the L331.52C cutter series. The PM chip breaker geometry supports stable chip formation at moderate to aggressive feed rates. The neutral hand orientation and positive rake angle make it adaptable to a range of milling strategies including face milling and square shoulder milling. Typical applications include roughing and semi-finishing passes on medium to large component features.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, TiN for extended tool life on steel and cast iron\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert  -  reduces per-edge tooling cost\u003c\/li\u003e\n\u003cli\u003ePositive rake with PM chip breaker geometry for controlled chip evacuation\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.80 mm reduces insert chipping at entry and exit\u003c\/li\u003e\n\u003cli\u003eScrew-lock holding method for rigid, repeatable seating in the toolholder pocket\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation  -  compatible with both climb and conventional milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in the L331.52C cutter series.
