It carries a TiAlN and TiN PVD coating applied over a submicron carbide substrate under manufacturer grade IC807, providing wear resistance and thermal stability across a range of workpiece materials. The insert measures 6.5 mm (0.2559 inches) in length with a 3\/8-inch (0.3748 inches) inscribed circle and a 1\/32-inch (0.0315 inches) corner radius. The HTW chip breaker geometry is engineered for controlled chip formation during moderate to heavy turning passes.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning operations in shop environments handling materials across ISO material groups H, K, M, P, and S, covering hardened steels, cast irons, stainless steels, carbon steels, and heat-resistant superalloys. It fits clamp and pin style toolholders that accept the WNMX insert style with an 80-degree trigon shape and N clearance code. Maximum depth of cut is 4.0 mm (0.1575 inches). Machinists and CNC operators performing finishing to semi-finishing passes on precision components will find the positive rake geometry and wiper edge useful for achieving tighter surface finish tolerances.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide submicron substrate with IC807 manufacturer grade for toughness and edge retention\u003c\/li\u003e\n  \u003cli\u003eTiAlN and TiN PVD dual-layer coating for oxidation resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003eHTW chip breaker optimized for controlled chip evacuation during turning\u003c\/li\u003e\n  \u003cli\u003eWiper edge geometry for improved surface finish in finishing passes\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle reduces cutting forces on workpiece and spindle\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin insert holding methods for secure seating in toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in WNMX-style clamp and pin toolholders accepting an 80-degree trigon insert with N clearance code, M tolerance code, and insert size code 342.
