A hand-held power tool, in particular a power screwdriver, includes a housing in which at least one drive motor is arranged for driving a tool receiving area. The drive motor can be activated via a manual switch, and the tool receiving area is designed to receive an insert tool. The hand-held power tool also includes an insert tool magazine for storing a plurality of selectable insert tools. The manual switch can be actuated in order to load a selected insert tool arranged in the insert tool magazine in the axial direction of the drive motor from the insert tool magazine into the tool receiving area and in order to activate the drive motor.

A tubular device for connection to a shaft such that a torque can be transmitted between the tubular device and the shaft comprises a hollow receiving region configured to receive a first supporting region of the shaft, and at least one first torque-transmitting section configured to engage with at least one second torque-transmitting section of the shaft. The hollow receiving region includes at least one contact surface configured to engage at least one first supporting region of the shaft when the tubular device is radially mounted to the shaft. The at least one first torque-transmitting section includes at least one bump which, starting from the at least one first contact surface, projects into the hollow receiving region and is positioned immovably on the tubular device.

A shaft for rotationally coupling a main device to a tubular device includes a first free end that is configured to be introduced into the tubular device, and a second end configured to be secured to the main device. The shaft also defines at least a first bearing region along an outer circumference that is configured to form a contact in a hollow accommodating region of the tubular device, and further includes at least one torque-transmitting section configured to engage with a torque-transmitting section of the tubular device. A securing device of the shaft includes a locking device that, in a locked state, is configured to prevent the securing device from being dismounted, and that, in an unlocked state, is configured to enable the tubular device to be dismounted. The securing device further includes an interlocking device that is arranged on the first end of the shaft, and that enables locking and unlocking the locking device.

An electric hand-held power tool for performing sanding work, in particular a finishing sander, is provided, that includes a drive plate ()&#x2014;which is drivable in a sanding motion using an electric motor&#x2014;and a sanding plate () attached thereto such that it is removable without the use of a tool, with means for attaching a sanding pad (). To create a multifunctional device with which various types of sanding work may be performed in an optimal manner, a tub-like recess () with a flat tub bottom () for receiving the drive plate () in a form-fit manner is formed in the top side of the sanding plate () facing the drive plate (); the sanding plate () is attached in a manner such that it is removable without the use of tools, preferably via a Velcro attachment between the tub bottom () and the surface of the drive plate (). The easy method of replacing the sanding plate makes it possible to quickly replace sanding plates () having different configurations for different requirements on sanding work (FIG.).
