    Abstract: A tool holder for a rotating and chiseling portable power tool is disclosed. A hollow spindle surrounds, coaxially with a working axis, a receiving space for receiving a tool. The hollow spindle has at least one cutout in the radial direction. An insert is inserted into the cutout in the radial direction. The insert has a rib that protrudes into the receiving space in the radial direction. A channel is arranged within the cutout and extends along the working axis. The channel is open into the receiving space and is bounded by the insert and an inner face of the cutout.

    Abstract: A power tool having a motor and an energy supply device, wherein an output current from the energy supply device to the power tool is greater than or equal to 70 amperes. The power-to-weight ratio of the power tool is in a range of greater than or equal to 0.30 kW/kg, for example. In addition, a power-to-weight ratio L of the power tool can preferably be in a range of greater than or equal to 0.30 kW/kg. In addition, a contact system for transmitting electrical energy from the energy supply device to the power tool is disclosed, wherein the contact system has at least one first contact and at least one second contact, wherein a contact area between the two contacts has a size of greater than or equal to 20 mm2.

    Abstract: A system including a machine tool and a power supply device, the power supply device being provided for supplying the machine tool with electrical power. The power supply device can be detachably connected to the machine tool by means of an interface, the interface coincluding at least one female contact partner and one male contact partner. The interface has at least one elastic means for reducing a relative movement between the male contact partner and the female contact partner, the at least one elastic device for reducing the relative movement between the contact partners being designed to engage with the at least one male contact partner and/or the at least one female contact partner. The power supply device includes at least one energy storage cell, the at least one energy storage cell having an internal resistance DCR_I of less than 10 milliohm. Methods for connecting a power supply device to a machine tool via an interface, and to an interface itself are also provided. A power supply device for use in the system.

    Abstract: A plug-in coupling (100) for making electrical contact with an electric drive (90) which is included in a hand-held power tool (200) and has a battery unit (20) which is to be accommodated by the hand-held power tool (200). The plug-in coupling (100) has at least one electrical contact plate (1) which is to be connected to the hand-held power tool (200), and at least one electrical contact spring pair (3) which corresponds to the contact plate (1), wherein the contact spring pair (3) is to be arranged on the battery unit (20) and is to be slid onto the contact plate (1) in the sliding-on direction (AR) and is to be withdrawn therefrom in the withdrawal direction (AB), wherein in the state in which contact is made (ZK) the contact plate (1) and the contact spring pair (3) form a frictionally locking latching-connection pairing.

    Abstract: A battery unit (100), which is designed for being received in a receiving recess (90) of an electrical hand-held power tool (200). The battery unit (100) includes a locking mechanism (10), which in a locking state (VZ) prevents the battery unit (100) from being pulled out of the receiving recess (90), wherein the locking mechanism (10) has an unlocking button (11) with a pressing area (13), by pressing and deflecting which the locking mechanism (10) can be brought into a release state (FZ), in which the battery unit (100) can be pulled out of the receiving recess (90) in a pulling-out direction (AR), wherein the pressing area (13) defines in the release state (FZ) and in relation to the pulling-out direction (AR) a first oblique plane (E1) in such a way that a vector component (FA) of an actuating force (FB) acting on the pressing area (13) is oriented in the pulling-out direction (AR).
