Porter-Cable 330 - Manual (Page 7)

In general, coarser grit sizes will remove the most material and finer grit sizes
will produce the best finishes.
Naturally, in all sanding operations, best results will be obtained if you select
the proper size and type of abrasives. Only garnet, aluminum oxide and
silicon carbide are recommended for use with finishing sanders. Flint paper is
not satisfactory for machine sanding, due to its weak structure.
Before starting to work, make sure you have the right abrasive for the
material on which the sander is to be used. Make sure you use the correct
size abrasive paper or cloth. Cut, do not tear, the abrasive sheets to size.
