ABSTRACT:
An inflatable sanding drum used for a drill or a lathe to said a wood has a cover between an abrasive member and a rubber bladder which defines an air chamber of the roller. Thus, even if the abrasive member is worn out by the friction with the wood surface, the rubber bladder is protected from damage. When the cover is damaged, it may be replaced with a new cover thus reducing the risk of damage to the rubber bladder.
