The Radius 360º is a drywall sanding tool with unique lateral, up-and-down, and circular motion. The ability to change direction quickly without having to lift the pad off the wall is a huge advantage over conventional drywall sanding. Unlike a conventional sander, the Radius 360º's foam disc wears evenly and lasts much longer. Both the foam pad and sandpaper use a hook and loop design, making replacement easy.
