Hook-and-loop sanding and surface-conditioning discs stick to a compatible backing plate to provide tool-free disc changes to minimize downtime and increase productivity. Unlike adhesive-backed discs, hook-and-loop discs can be reused after they've been removed from the backing plate. Sanding discs attach to a power sander and use a coated abrasive for smoothing surfaces. Surface-conditioning discs made of nonwoven nylon remove surface imperfections and create a smooth surface ready for finishing.
