Manufactured from solid carbide and finished with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, this insert is engineered for consistent performance in stainless steel and other ISO M-class workpiece materials. It features an 80-degree diamond insert shape, a 3\/4 inch inscribed circle, and a 3\/64 inch corner radius (0.0469 inches), providing a balance of cutting edge strength and surface finish capability. The neutral hand orientation makes it suitable for both right- and left-hand toolholder setups. CNC machinists and tooling specialists working in production turning environments are the primary installers of this insert.\u003c\/p\u003e\u003cp\u003eThis insert is part of the SANDVIK COROMANT T-Max P series, a platform commonly used in external turning, facing, and profiling applications. The MR chip breaker geometry is suited for medium to finishing cuts in stainless steel, providing reliable chip control across a range of feed rates and depths of cut. The four cutting edges per insert support cost-effective indexing in production environments. Applications include both roughing-to-finishing transitions and continuous cuts on austenitic and duplex stainless steel components in industrial manufacturing settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for wear resistance and thermal protection\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (CNMG) with 4 usable cutting edges\u003c\/li\u003e\n\u003cli\u003e3\/4 inch inscribed circle with 3\/64 inch corner radius for medium to finish turning\u003c\/li\u003e\n\u003cli\u003eMR chip breaker geometry optimized for stainless steel and ISO M-class materials\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation compatible with standard CNMG toolholders\u003c\/li\u003e\n\u003cli\u003eClamp and pin insert holding method for secure seating in the pocket\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNMG-style toolholders within the SANDVIK COROMANT T-Max P series.
