Pads, protectors and dust collection for the random-orbit sanders. Pads come in the machine diameters in hard, soft and supersoft — match hardness to the shape of what you're sanding, not to the machine. Edge protectors take the contact when the sander meets a wall or an adjacent panel. Long-life chip bags and turbo filter bags handle extraction where an extractor isn't connected; they're the difference between a sander that keeps its own cut clear and one that grinds its own dust back into the surface.
