This listing is for a pack of 3 new Tungaloy CPMT09T308-PS AH120 square carbide turning inserts, manufactured in Japan. Decoding the ISO designation: C = 80° rhombic (square) insert shape, P = 11° clearance angle, M = ±0.05–0.13 mm tolerance class, T = insert with hole and chipbreaker on one face, 09T3 = 9.525 mm (3/8 in) inscribed circle with 3.18 mm thickness, 08 = 0.8 mm nose radius, PS = Tungaloy's precision-ground positive-rake chipbreaker geometry optimized for light to medium turning of steel. The AH120 grade is Tungaloy's PVD-coated (TiAlN-based multilayer) cemented carbide, engineered for steel turning (ISO P application group) and confirmed on the package label alongside ISO work material classifications P and M as first-choice, with N, S, and H as secondary. Per the visible label, the insert targets a feed rate of 0.08–0.3 mm/rev (0.003–0.012 ipr) and a cutting speed of 50–200 m/min (164–656 sfm) on steel. These inserts are compatible with CPMT-style toolholders accepting 09T3 geometry and are suitable for CNC turning centers performing finishing to medium stock-removal passes on carbon and alloy steels.
