It features an alumina TiC substrate with a PVD-applied TiN coating and a flat-top chipbreaker geometry. The insert measures 0.433 inches in length with a 0.25-inch inscribed circle and a 0.0315-inch corner radius. With 3 cutting edges, a 60-degree triangular shape, and a positive rake angle, it is suited for turning, facing, and boring operations where tool life and surface consistency on hard workpieces are the priority. Licensed machinists and CNC tooling technicians are the primary installers.\u003c\/p\u003e\u003cp\u003eThis insert is intended for machining hard materials, designated under ISO workpiece material code H. Its flat-top, honed cutting edge style and neutral hand orientation make it adaptable across turning, facing, and boring applications. The maximum depth of cut reaches 0.0787 inches. It fits into standard TPGN-style toolholders using a clamp-style holding method, making it compatible with a wide range of production turning setups in both job-shop and high-volume manufacturing environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlumina TiC ceramic substrate with PVD TiN coating for hard-material performance\u003c\/li\u003e\n\u003cli\u003eTPGN222 geometry: 60-degree triangle, 0.25-inch inscribed circle, 11-degree relief angle\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0315 inches with honed cutting edge for controlled engagement\u003c\/li\u003e\n\u003cli\u003e3 usable cutting edges per insert, neutral hand for versatile mounting\u003c\/li\u003e\n\u003cli\u003eFlat-top chipbreaker with positive rake angle suits turning, facing, and boring\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and ISO insert standards; industry standard number TPGN 222\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to seat in standard TPGN-style clamp-type toolholders conforming to ANSI and ISO specification TPGN 222.
