Tungaloy CPMT09T308-PS AH120 Square Carbide Turning Insert (10pc)

The Tungaloy CPMT09T308-PS AH120 (also cataloged as CPMT 32.52 PS AH120) is a new, factory-sealed 10-piece box of square (80°) positive-rake carbide turning inserts with a 7° clearance angle, medium tolerance class, and a central cylindrical hole for screw clamping. The "PS" chipbreaker geometry is a polished, precision-ground positive-rake breaker optimized for light-to-medium finishing and semi-finishing operations, particularly on steel (P-class), with the label confirming feed range f = 0.08–0.3 mm/rev (0.003–0.012 ipr) and cutting speed Vc = 50–200 m/min (164–656 sfm). The AH120 grade is Tungaloy's PVD-coated (TiAlN-based) cemented carbide engineered for steel and difficult-to-cut materials, delivering thermal resistance and edge toughness at low-to-moderate cutting speeds; the deep black PVD finish is clearly visible across all inserts in the photographs. With an inscribed circle of ~9.525 mm (3/8 in), a 3.18 mm thickness, and a 0.8 mm nose radius, these inserts are compatible with SCLP/SCMT-style positive toolholders requiring CPMT 09T3 inserts. The material applicability shown on the label covers P (steel), M (stainless), K (cast iron), N (non-ferrous), S (superalloys), and H (hardened), with P as the primary and dominant application. Made in Japan.
