This insert features a TiAlN and AlCr2O3 PVD coating for enhanced wear resistance and thermal stability at the cutting edge. The 80-degree diamond shape (C-style) provides a strong, versatile cutting geometry suited to a wide range of turning applications. With a 1\/2-inch inscribed circle, a 1\/32-inch corner radius, and a neutral hand orientation, it fits standard CNMG toolholders secured by clamp and pin holding methods. This insert is part of the Sandvik T-Max P series and is primarily intended for use by CNC machinists and toolroom professionals.\u003c\/p\u003e\u003cp\u003eThis insert is engineered primarily for machining stainless steel, with secondary suitability for superalloys and titanium. These are demanding workpiece materials that require a tough, thermally stable coating and a controlled chip breaker geometry. The SMR chip breaker geometry is designed to manage chip flow and reduce cutting forces in these difficult-to-machine materials. It is well suited to finishing and semi-finishing passes on components in aerospace, medical, and industrial manufacturing environments where surface integrity and dimensional accuracy are critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiAlN and AlCr2O3 PVD coating provides thermal resistance and extended tool life in stainless steel and superalloy cutting\u003c\/li\u003e\n\u003cli\u003eSMR chip breaker geometry controls chip flow in difficult-to-machine materials\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (CNMG style) delivers a strong cutting edge with versatile approach angle options\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation compatible with both right- and left-hand toolholder setups\u003c\/li\u003e\n\u003cli\u003eClamp and pin insert holding method ensures secure seating under heavy cutting loads\u003c\/li\u003e\n\u003cli\u003e4 cutting edges per insert for cost-effective indexing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard indexable insert for CNMG-style toolholders accepting a 432 insert size with clamp and pin holding.
