I'm not sure exactly what the grit number would be. But there are two different sides - one is slightly finer than the other. I never use clippers, just this file - the one side to shape and the finer side to smooth the edges.
I don't know the grit of this file, but can tell you that I have dry and brittle nails, and this file is very gentle, leaves no rough edges-will buy several more for purse, nightstand, etc.
It does not have a rough grit. One side is a little stronger than the other, but both sides are a mild grit. They work fine for me and I play guitar and file my nails down every week.
