Here’s the 80 grit Nylon Abrasive Cup Wheel that I think Nycole has used. I’m sorry to say that this isnt a good tool to use on most tile for most cases. Unfortunately, this particular nylon bristle product is rather unique as it has abrasive impregnated into the nylon bristles....and would be quite as damaging to the tile surface as if sandpaper was used to clean a car instead of a soapy sponge. But...

I don’t quite understand. Are you saying instead of running the wheel where all the bristles simultaneously made contact with the tile (drill would be perpendicular to the floor) that you laid it don’t on its side like a wheel to a car makes contact with the ground and the metal perimeter of this cup ground against the tile?
