Assorted grits: 180, 220 and (2) 120 grit Scroll Sander sanding belts. Easily smooth the edges of scroll saw projects in wood, plastic, metal and composites. These fabric-backed belts have molded polycarbonate ends for attaching to most scroll saws that take 5" pin end blades.

For best results work at lower speeds!
