This is a factory-new 10-piece box of Kyocera CNMG120412MS (CNMG432MS) carbide turning inserts in grade PR015S, Kyocera item number 41604570. The CNMG designation decodes as: C = 80° diamond shape, N = 0° clearance angle (negative rake), M = ±0.08mm IC/±0.05mm thickness tolerance, G = cylindrical hole with chip groove on both faces; size 12 = 1/2 in (12.7 mm) inscribed circle, 04 = 4.76 mm thickness, 12 = 1.2 mm nose radius; MS is Kyocera's medium-to-light chipbreaker geometry suited for a wide range of turning operations. Grade PR015S is a PVD-coated cemented carbide with Kyocera's MEGACOAT NANO multilayer coating, targeting ISO P, M, K, N, and S work material groups as shown on the package label, with particular strength in steel and stainless steel turning at medium cutting conditions. These inserts are manufactured in Japan (JP lot code visible) and are compatible with CNMG-style negative toolholders using a 1/2 in IC seat, such as MCLNR/L, DCLNR/L, and PCLNR/L style holders.
