Bosch Tool is the manufacturer of a number of power tools, including saws, sanders, drills and much more. Bosch offers a variety of random orbital sanders, in both a palm-style grip, or with an elongated body for two-handed operation. In either case, the motor employs an armature that utilises a pair of brushes that can wear out over time. Replacing the brushes on a Bosch DVS random orbital sander requires only a bit of time and a couple of screwdrivers.
