A power tool includes a housing. A motor is housed in the housing. A platen is driven by the motor. The housing includes a first housing part, a second housing part and a third housing part. The housing defines a battery receptacle portion configured to receive a removable battery pack which powers the motor. Each of the first housing part, the second housing part and the third housing part form part of the battery receptacle portion.

An electric power tool having a rotating tool. The electric tool is characterized in that a direction of rotation of the tool on the electric power tool can be set in dependence on an operating state of the electric power tool. The automatic settability of the direction of rotation of the electric tool is associated with the advantage that no gearbox for changing the direction of rotation, as in an internal combustion engine, is required. In addition, the user-friendliness of the electric power tool for the user can be significantly improved, since the user practically no longer has to worry about setting a “correct” direction of rotation of the tool. In a further aspect, the invention relates to a method for operating an electric power tool having a rotating tool, wherein the direction of rotation of the tool on the electric power tool is set in particular in dependence on whether or not a suction device is connected to the electric power tool.

In an automatic wet sanding apparatus including a disc and a cushion pad, a disc center hole is formed at a central portion of the disc and a pad center hole is formed at a central portion of the cushion pad. Water having been supplied to an introduction space inside a skirt is stirred as an eccentric head rotates eccentrically and thereby pushed out toward a painted surface via the disc center hole and the pad center hole with enhanced pressure. Thus, sanding dust resulting from automatic wet sanding can be washed away toward an outer circumferential side by the water that is pushed out toward the outer circumferential side, so that the likelihood of clogging due to sanding dust can be reduced and high sanding efficiency can be maintained.

The present disclosure relates to a grinding head (1) for a floor grinding machine for grinding floor surfaces of stone or stone-like material. Such a grinding head (1) comprises a lower casing member (3), comprising a lower support (31) and an upwardly extending edge portion (32), and an upper casing number (2), comprising an upper cover (21) and a downwardly extending edge portion (22), wherein the upper casing member (2) is joinable to the lower casing member (3) by causing axially distal portions of the edge portions to bear on each other.
