A round sanding pad is covered with an abrasive material, which is circularly driven via a flywheel as in the orbital sander. In addition to the circular motion, the sanding pad rotates. The sandpaper is fixed on the sanding plate with a hook and loop. The additional rotary movement of the sanding pad greatly increases the removal rate. The rotary sander doesn’t vibrate. The pad is linked directly with the tool’s motor and therefore gets its full power.
