Carrying the 1115 manufacturer grade and a PVD-applied TiAlN and AlCr2O3 dual-layer coating, it is engineered primarily for machining stainless steel, with secondary suitability for superalloys and titanium. The insert features an 80-degree diamond shape, a sharp SGF chip breaker geometry, and a 0.20 mm corner radius for controlled, clean cuts at tight tolerances. It belongs to Sandvik Coromant's T-Max P series and is installed by CNC machinists and toolroom technicians on lathes and turning centers requiring consistent insert geometry and coating performance.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for finishing and semi-finishing passes on stainless steel and difficult-to-machine materials including superalloys and titanium. The SGF chip breaker is optimized for light to medium depths of cut, making it a practical choice in precision turning applications where surface finish and edge integrity are critical. With four available cutting edges per insert and neutral hand orientation, it fits standard CNGG-style toolholders used in both production and job-shop turning environments. The 0.5000 inch inscribed circle size and 3\/16 inch thickness are common dimensions in medium-range turning toolholder systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePVD-coated TiAlN and AlCr2O3 dual-layer coating for heat resistance and wear performance on stainless steel and superalloys\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (CNGG style) with sharp SGF chip breaker for controlled chip formation\u003c\/li\u003e\n  \u003cli\u003e0.20 mm corner radius for tight-tolerance finishing and semi-finishing passes\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert, neutral hand, maximizing tool economy\u003c\/li\u003e\n  \u003cli\u003eClamp and pin insert holding method for secure seating in compatible toolholders\u003c\/li\u003e\n  \u003cli\u003eT-Max P series with ISO code CNGG 12 04 02-SGF 1115 for straightforward cross-referencing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNGG-style turning toolholders compatible with a 0.5000 inch inscribed circle and 3\/16 inch insert thickness.
