A power tool is provided comprising: a power source; a power tool housing comprising a first mechanical coupling connectable with a second reciprocal mechanical coupling on a power tool accessory; and a first electrical coupling in electrical connection with the power source and mounted on the first mechanical coupling. The first electrical coupling is electrically connectable with a second reciprocal electrical coupling on the power tool accessory.

A dust collecting device for a power tool, the dust collecting device having a lamella filter and a rotatable shaft. In the collecting container of the dust collecting device, the lamellae of the filter can be set in an axial movement by a rotary movement of the shaft which is interrupted when the filter lamellae arrive in the region of release of the shaft. The release enables the lamellae to return to their original position, the return of the lamellae to this original position causing the lamellae to vibrate, which leads to the filter being cleaned. A power tool which has a proposed dust collecting device, as well as a method for operating a power tool and for cleaning a filter is also provided.

A drill comprising: a body, the body comprising a housing formed internally with at least two chambers; a rear handle mounted on the body; a tool holder mounted on the front of the body; an electric motor mounted in a first chamber, the electric motor comprising an end cap attached to a motor housing; a transmission mechanism mounted in a second chamber which is in driving connection with the electric motor, the transmission mechanism being driven by the electric motor when the electric motor is activated to either impart impacts to and/or rotate a cutting tool when held by the tool holder. The end cap engages with the housing to form a separating wall which separates the first and second chambers.

A dust collector includes a main body, a sliding part, and a communication passage. The main body includes an internal region disposed between a power tool and a dust storing region. The sliding part is held by the main body so as to be slidable in a first direction while partly protruding out of the main body through an opening and partly disposed in the internal region. The communication passage extends in a second direction crossing the first direction within the internal region. When the sliding part is placed at a closest position, a distance in the first direction between the opening and an innermost end of the sliding part is longer than a distance between the opening and the communication passage. The sliding part includes an interference avoiding part configured to avoid interference with the communication passage when the sliding part is placed at the closest position.

A hand-held power tool, in particular a hammer drill or combination hammer, is disclosed. The power tool includes a tool housing which has a receiving recess designed to replaceably receive a storage battery or a power supply unit. The hand-held power tool further includes an electric drive motor having a cooling fan and a first vent portion which is located on the tool housing outside the receiving recess and through which a volume flow generated by the cooling fan can be guided. The tool housing has a second vent portion which is different from the first vent portion and which is located in the receiving recess and through which the volume flow generated by the cooling fan can be at least partially guided.

A power tool, such as an impact driver, includes a motor having a rotor that rotates relative to a stator, and a centrifugal fan that rotates together with the rotor. A motor housing and a rear housing house the motor. Overlapping parts of the motor housing and the rear housing radially surround an outer circumference of the centrifugal fan. Air exhaust ports are defined in each of the overlapping parts and are offset in an axial direction of the rotor. Fluid communication paths are defined between the air exhaust ports in the overlapping parts. The fluid communication paths have an opening area or width in the axial direction that is smaller than an opening area or width in the axial direction of the air exhaust ports.
