SANDPAPER/SANDING DISCS
SANDPAPER INFORMATION GUIDE
What is Grit?
“Grit” is a reference to the number of abrasive particles per inch of sandpaper. The lower the grit the rougher the sandpaper and conversely, the higher the grit number the smoother the sandpaper. This make sense if you imagine how small the particles on an 800-grit sandpaper would need to be to fit into a 1" square. Sandpaper is referred to by the size of its grit.
