60-grit discs are the matching item to 60-grit belts on the drum sander. If you had to sand the middles of your floor with 60-grit on the drum, you will most definitely need 60-grit to sand the edges. In the universe of floor sanding grits, 60-grit counts as the first fine grit. It has a very simple job: it reduces the scratches from the 36-grit mineral and leaves a scratch that can easily be removed by 80-grit, the last grit in the typical floor sanding sequence. If you skip 60, the 80-grit paper will not be able to make the 36-grit scratch disappear. We’ve tried it, but it just leads to tears.
But 60-grit should never be your final grit either because it leaves a scratch in wood that is still quite visible to the naked eye. 60-grit is a crucial link in the sequence of your sanding grits, but rarely gets to be the star.
