This decision is made by the type of abrasive and grit you have selected or the type of process you will be performing with the abrasive. Paper – Used mainly for wood finishing in weights from A, C, D, E and F. A is the lightest weight. Cloth – Produces a flexible backing in a wide range of weights. The more popular J and X weights are standard stock items. The J weight is the lightest and most flexible whereas the X weight is a heavier backing providing the widest range of use. The weight of the backing is usually specified after the grit number. For example, 40D means 40 grit with “D” weight backing.
