Kyocera DB187FNRT00420 Carbide Inserts

Got a pack of Kyocera carbide inserts here. The label says DB187FNRT00420 and they're made in Japan. These are for industrial machining and metalworking. The box is still sealed and has all the safety warnings on the back. If you do any lathe work or milling you probably know what these are. Just trying to clear out some extra shop supplies I don't need right now.
