The rotary sander has a good material removal output. A rotary sander can remove thick layers of rusts and paints over a large covering. This tool is perfect for works like sanding paint, wood, and plastic, varnish, polishing metal or removing rust. The rotary sander has a round pad but as compared to a random orbital sander it does vibrate. The rotary pad is connected straightly with the tool’s motor and therefore it gets full power. Industrial use: Auto body repair industry and woodworking industry have more use.
