Sponsored: These Hi-Flex Foam Sanding Pads are some of the newest and best quality foam sanding pads on the market. Made from dense foam and evenly coated on one side with aluminum oxide grit, these pads measure 4-1/2″ × 5-1/2″ × 3/16″ thick. This makes for an extremely long-lasting pad that’s very flexible for finish sanding on contoured parts, routed profiles and carvings. Depending on the grit, they’re also great for whitewood sanding or sanding between coats of a finish. Made by Klingspor, these are quality sanding pads.
