These Scroll Sanders Plain End 180 grit x 1/2" are just as easy to attach as a regular scroll saw blade. The scroll sanders will sand narrow internal cuts, remove bumps, gouges, burn marks, and feathering. Each sander lasts many hours. Will fit into holes as small as 1/4 inch. The scroll sander sanding belts easily smooth the edges of scroll saw projects in wood, plastic, metal and composites. The fabric backed belts have molded polycarbonate ends for attaching to most scroll saws that take 5" standard blades. Remount the scroll sander with the opposite end up to double the life of your scroll sander!
