Front	Soft	Back	Hard

Thread one of these pads onto the tool's arbor. Once the pad is secured, you can quickly attach, remove, and reuse hook and loop sanding discs.

Soft—Soft pads have a thicker layer of foam than hard pads, which conforms to contoured surfaces. They're also great for finishing work.

Hard—Hard pads are best for aggressive cutting on flat surfaces.

For 7" Diameter Disc—Pads for 7" and 9" disc diameter have a scalloped edge that applies less pressure on the work surface, reducing operator effort.
