Abstract: An electric hand-held power tool for performing sanding work, in particular a finishing sander, is provided, that includes a drive plate (16)—which is drivable in a sanding motion using an electric motor—and a sanding plate (21?) attached thereto such that it is removable without the use of a tool, with means for attaching a sanding pad (22?). To create a multifunctional device with which various types of sanding work may be performed in an optimal manner, a tub-like recess (23) with a flat tub bottom (231) for receiving the drive plate (16) in a form-fit manner is formed in the top side of the sanding plate (21?) facing the drive plate (16); the sanding plate (21?) is attached in a manner such that it is removable without the use of tools, preferably via a Velcro attachment between the tub bottom (231) and the surface of the drive plate (16).

Abstract: A motor-driven machine tool (1) for tools which are to be driven rotationally has, configured as a hand-held machine tool, a pistol-shaped basic shape, in which, lying one behind the other in the stock part (2) in the direction of the main axis, a motor (4), a gear mechanism (5) and a tool changing magazine (6) are provided as a structural unit, wherein the tool changing magazine (6) which is designed, in particular, as a drum magazine is mounted on a neck (24) of the gear mechanism housing (22) and is penetrated by the output shaft (23) of the gear mechanism (5).

Abstract: The invention is based on a power tool, in particular a handheld electric power tool, having a housing (10) with a coolant duct arrangement, having through openings (14), for a cooling medium for cooling at least one motor located in the housing (10). It is proposed that the through openings (14) each have cross-sectional areas in the range from 0.15 mm2 to 10 mm2. A coolant duct arrangement is also proposed.

Abstract: The invention is based on a hand power tool, in particular a disk-type sander, that comprises a motor (12) with a drive shaft (14) located in a housing, whereby the drive shaft (14)—by way of its side furthest from the motor (12)—is joined via an eccentric (18) with a sanding disk (16) that can walk around an annular, turnably supported means (20, 72) that is capable of being braked via braking means (22, 62). It is proposed that the annular means (20, 72) are supported in the braking means (22, 62).

Abstract: A handheld machine tool, for example a circular saw, has a disk-shaped tool which is driven in rotation in a housing which holds a drive motor and a tool shaft carrying the tool. The tool can be clamped between a clamping nut, a clamping screw, and two supporting flanges. One supporting flange can be rotated easily relative to the tool shaft without use of auxiliary tools and is supported with an extensive friction at the tool. This supporting flange can be dependably clamped or loosened without tools. The machine tool further has an adjusting device which is coupled with that supporting flange to displace the latter axially toward the tool when that supporting shaft is rotated relative to the tool shaft due to rotational driving. The adjusting device therefore clamps the tool with an increasing force and tries to displace that supporting flange axially away from the tool automatically when the tool is stopped and accordingly reduces the clamping force.

Abstract: The hand-held machine tool has a tool holder (20) provided with a receptacle (19) into which a shaft portion (15) of a tool (16) is axially insertable. The tool holder (20) has a longitudinal axis (11) and includes a guide device (18) for axially guiding the tool (16); a device (23) for rotary slaving of the tool (16); a retaining device (28) for axially securing the tool (16) and a locking member (34) for locking the retaining device (28) in an open configuration for insertion or removal of the tool (16). The retaining device (28) is located in front of the guide device in an insertion direction of the tool (16) in the tool holder (16). The retaining device (28) is provided with an opening (31) for passage of the tool (16) through it.
