A: We do not recommend using the 7in. 16-Grit Abrasive Grinding Disc to rough up concrete to create a non-slip surface. These discs are manufactured to remove adhesives and coating from concrete.
A: I didn't need to use the adaptor.
A: not necessary very useful for dust collection Like some kind of shroud around the dics.
A: Yup, removed the surface of my concrete floor...if I pushed down hard enough, it really dug in deep.
A: Yes. Silicon carbide is meant to lightly sand rock type surfaces without sparks.
