It features an 80-degree diamond insert shape (Shape Code C) with a positive rake angle of 10 degrees and a 7-degree relief angle. The insert is coated with TiAlN via a PVD coating process, which delivers thermal resistance and wear protection across a wide range of workpiece materials. The JS chip breaker geometry promotes controlled chip flow during turning, facing, and boring operations. A licensed CCGT-style insert, it suits both finishing and semi-finishing passes. Installation and operation require a compatible screw-lock toolholder matching the CCGT insert pocket specification.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning, facing, and boring applications across a broad range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. It is applicable in both light and moderate cutting conditions and is appropriate for use in production and job-shop environments where tool versatility across multiple material grades is required. The neutral hand orientation allows use in standard right-hand or left-hand setups depending on toolholder configuration. Machinists and CNC operators working in aerospace, general metalworking, and precision manufacturing will find this insert applicable to common finishing and semi-finishing turning cycles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiAlN PVD coating on AH725 carbide grade provides thermal and abrasion resistance for extended tool life\u003c\/li\u003e\n  \u003cli\u003eJS chip breaker geometry controls chip evacuation during turning, facing, and boring\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (CCGT) with positive 10-degree rake reduces cutting forces on workpiece\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.1181 inches supports light to semi-finishing pass depths\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style improves edge stability and reduces micro-chipping on entry\u003c\/li\u003e\n  \u003cli\u003eCovers six primary workpiece material groups: P, M, K, N, S, and H material codes\u003c\/li\u003e\n  \u003cli\u003eMulti-use insert certified to ANSI and ISO standards for cross-platform toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in screw-lock CCGT-style toolholders accepting a 3\/8-inch inscribed circle insert with a 0.1730-inch hole diameter.
