Specialized CNC grinding, slotting, and cutoff machines

Item Condition Notes

Status: New Old Stock (NOS) — This wheel is brand new, unmounted, and has never been used.
Cosmetic Details: Due to extended storage in an industrial warehouse environment, the wheel shows surface debris, light oxidation on the metal hub and diamond section, and superficial scratches on the metal core (visible in the provided photos).
Performance: These cosmetic issues are purely visual blemishes from long-term shelf life and will not affect the wheel's cutting performance, structural integrity, or lifetime.
