It features an 80-degree trigon (W-shape) geometry with a positive rake angle of 18 degrees and a TiAlN PVD coating applied under the WNN10 grade designation. The insert carries a 3\/8-inch inscribed circle, a 0.016-inch corner radius, and a maximum depth of cut of 0.257 inches. The FN2 chipbreaker geometry and honed cutting edge make it well-suited for finishing and semi-finishing operations on non-ferrous metals. Licensed machinists and CNC operators install this insert in screw-clamped toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is optimized for primary use on non-ferrous metals, including aluminum and copper alloys, and is rated as a secondary option for steel and stainless steel workpiece materials under ISO material codes P and M. The neutral hand orientation allows use in both right- and left-hand toolholder configurations. Multi-use application includes turning, facing, and boring operations. The WCGT insert style with clearance code C and tolerance code G is sized to the 32.51 insert size code, corresponding to ISO designation WCGT06T304-FN2 WNN10 and industry standard number WCGT3(2.5)1-FN2 WNN10.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiAlN PVD coating under WNN10 grade for thermal resistance and tool life on non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e80-degree trigon shape (insert shape code W) with positive 18-degree rake for reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eFN2 chipbreaker geometry suited to finishing and semi-finishing passes\u003c\/li\u003e\n\u003cli\u003eThree cutting edges per insert for extended usable life\u003c\/li\u003e\n\u003cli\u003eHoned cutting edge style for clean surface finish on non-ferrous workpieces\u003c\/li\u003e\n\u003cli\u003eScrew-holding method compatible with standard WCGT-series toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit insert for screw-clamped WCGT-series turning toolholders conforming to ANSI and ISO standards.
