A hand-held/hand-guided random orbital polishing/sanding power tool has a static body and a motor for driving an eccentric element with a rotational movement about a first rotational axis, and a plate-like backing pad rotatably connected to the eccentric element about a second rotational axis. The first/second axes extend parallel to and spaced apart from one another. Part of an external circumferential surface of the eccentric element has a rotational symmetry re the first axis to form a rotationally symmetric part. The tool has a first bearing between the rotationally symmetric part and the static body so the eccentric element is rotatably guided re the static body about the first axis, and also having a mechanical gear arrangement with two meshing gear wheels arranged between the motor's drive shaft and the eccentric element, and one meshing gear wheel attached to the eccentric element for transmitting torque thereto.

A hand-held machine tool (1) for sanding or polishing a workpiece features a housing (2); a motor (4) for rotating a tool shaft (5) of the machine tool about its axis of rotation (6); and a backing pad (3) for releasable attachment of a sanding or polishing element thereto and eccentrically attachable to the tool shaft by an eccentric element (11) to allow the backing pad to perform a working movement. The machine tool implements different working movements of the backing pad attached thereto. The housing includes first magnetic elements (16) facing the backing pad. The backing pad attached to the eccentric element includes second magnetic elements (17) facing the housing. The machine tool implements a first working movement if a magnetic force is active between some first and second magnetic elements and a second working movement if no magnetic force is active between the first and second magnetic elements.

A power tool includes a grinder, sander or a polisher, which has two working modes. According to an embodiment a dual power tool includes a motor operable in two operational directions, where an operational mode of the dual mode power tool is changeable by changing operational direction of the motor.

A handheld multifunction power tool includes a driveshaft, a hub assembly, and a stem. The hub assembly includes an outer hub and an inner hub that is rotatably coupled with the inner hub and rotatable with respect to the outer hub. Rotation of the inner hub relative to the outer hub facilitates selection from among a rotary mode and a random orbital mode.

A portable abrading machine includes an abrading-machine main body, a battery holster, and a power-supply cord. The abrading-machine main body includes a main-body housing, which houses a motor, and an abrading part, which is configured to move with orbital motion when a motor shaft of the motor is rotated. The battery holster includes a battery-mounting part, on which a battery is mountable. The power-supply cord is configured to supply electric power from the battery, when mounted on the battery-mounting part, to the abrading-machine main body. The power-supply cord connects the abrading-machine main body and the battery holster without going through the housing.

A hand-held electric power tool comprising an elongated tool housing, that supports an electric motor, and a moveable backing plate protruding externally from the tool housing. The electric motor actuates the backing plate, and the backing plate performs a rotational, random-orbital, orbital or gear-driven working movement in its plane of extension. A bottom surface of the backing plate detachably holds a polishing or sanding member. The tool housing has a rear part formed to be gripped by a hand of a user of the power tool thereby holding the power tool during its intended use and a tubular front part from which the backing plate protrudes, the front part having a smaller diameter than the rear part and being attached to the rear part. At least part of the electric motor may be accommodated in the tubular front part of the tool housing.
