2piece set of 5 inch (125 mm) soft sponge interface pads for hook and loop sanding discs and backing pads. Designed to improve contact on uneven surfaces, these pads provide cushioning and support for smoother, more consistent sanding results. Key benefits Better contact on uneven surfaces: the soft 12 mm sponge conforms to contours for closer edge sanding and more even abrasive contact. Easier tool handling: cushioning helps reduce orbital sander vibration for steadier control and a finer finish. Longer disc life: the 8hole pattern helps clear debris from the work surface, reducing clogging and extending the useful life of sanding discs. Quick changes: hook and loop connection allows fast attachment between sanding discs and backing pads.
