6 x 1.5-inch Diamond Wheel, 100 Grit.  Genuine CabKing wheel, brand new in original box.  Plastic hub.  Use wet.

CabKing diamond grinding wheels are manufactured using the highest quality diamonds to provide you a longer grinding life and clean, faster cutting. They are nickel electroplated using commercial grade diamonds uniformly throughout the entire width of the wheel, making them more durable and aggressive than silicon carbide wheels while giving you excellent quality and results. All wheels are made with a plastic center core, which puts less stress on machine bearings when compared to wheels with steel hubs because they are lighter.
