A hand-held power tool includes a housing in which a drive unit for actuating a tool holder is arranged. The housing forms a handle for holding the hand-held power tool. At least one fastening region is associated with the housing to which a safety loop for securing the hand-held power tool against falling can be fastened. The at least one fastening region has an optical and/or haptic marking element for marking the at least one fastening region.

An accessory device for a hand-held power tool includes a dust collection box that has a housing and a filter unit configured to filter an airflow. The housing is configured to be connected to a housing of the accessory device via a first securing unit. The filter unit is configured to be connected to the housing of the dust collection box via a second securing unit. The filter unit has a first sealing element arranged on the dust collection box side and a second sealing element arranged on the accessory device side. The filter unit is sealed from the housing of the dust collection box and the housing of the accessory device via the first and second sealing elements. The hand-held power tool in one embodiment is configured with a percussive mechanism.

A vacuuming-off device includes at least one vacuuming-off unit that has at least one interface. The interface is mechanically and electrically connectable to a hand-held power tool, in particular to a hammer drill and/or chipping hammer, in at least one first application. The vacuuming-off device further includes an adapter unit that, in at least one second application, is connectable to the interface. The adapter unit has at least one connecting unit that is connectable to at least one energy supply.

Vacuuming-off device

A hand tool machine device with a drive unit comprising at least one drive shaft, a transmission unit including at least one transmission element, a cooling unit including at least one fan element, and at least one sealing element configured to seal the transmission unit in at least on axial direction. The at least one fan element includes at least one receiving region configured to at least partially receive the at least one sealing element.

Hand tool machine device

A hand-power tool, in particular a drill and/or chiseling hammer, includes a transmission, a machine housing, and an inner housing arranged within the machine housing. The inner housing is provided for at least partially receiving at least one transmission element of the transmission. The at least one transmission element is supported jointly by the inner housing and by the machine housing.

Portable power tool

A hand power tool device includes at least one drive unit, which has at least one drive shaft. The hand power tool device also includes at least one transmission unit which has at least one transmission element that is directly connected to the drive shaft. The hand power tool device also includes at least one cooling unit which has a fan element. The fan element is at least substantially directly connected to the at least one transmission element of the at least one transmission unit.

Hand power tool device

A hand-held power tool includes a tool housing and a handle housing. The handle housing is movable relative to the tool housing. The hand-held power tool also includes an electric motor for driving the hand-held power tool. The electric motor is switched on and off by a relative movement of the handle housing relative to the tool housing. The hand-held power tool also includes a main electrical switch configured to apply an electrical voltage supply to the electric motor. The main electrical switch is switched by an actuating mechanism. The main electrical switch is actuatable with the aid of a movable component that is movable relative to the tool housing handily via the actuating mechanism, either directly or by the actuating mechanism.

The invention relates to a hand-held machine tool, in particular a hammer drill and/or chipping hammer. The tool according to the invention has a transmission device with a drive bearing that has at least one torque-transmitting means with a transmitting contour for transmitting a torque onto the drive bearing. According to the invention, the transmitting contour of the torque-transmitting means is produced by axial machining and/or a stamping and/or planning process.

Hand-held machine tool

The invention relates to a gearbox device, in particular, for a hammer drill or chisel, with a torque transmission mechanism, which has a first torque transmitting region for transmission of a torque to a first component and at least one second torque transmitting region for transmitting a torque to a second component. According to the invention, the first torque transmitting region and the second torque transmitting region at least partly have a corresponding partial contour for transmitting the torques.

Transmission device

A drill hammer for the three operation modes of drilling, chiseling, and hammer-drilling has a motor with a motor shaft; a gear with an intermediate shaft, a driving gear wheel, a toothed slaving shaft , a shifting hub, and a driven gear wheel; a percussion mechanism with a wobble disk and a wobble gear wheel; and a driven shaft with a driving gear wheel and a drill chuck. The gear is configured to be changed over easily without axial displacement of running gears that mesh with one another so that the drill hammer is more robust, shorter or more compact, and lighter in weight. The drill hammer is thus simply and economically constructed and whose efficiency is not impaired by the gear shifting mechanism.

Drill hammer with three modes of operation

The invention relates to a hand-held power tool, in particular a hammer drill which has a hammer drive, a rotary drive, a switching device, and a main output element. The switching device has a slide mechanism, which is designed for switching between different operating modes. According to the invention, the slide mechanism has at least one coupling element, which in at least one operating mode is directly coupled to a coupling element, the latter being rotationally fixed to the main output element.

Hand-held power tool

The invention relates to a handheld machine tool, in particular a hammer drill and/or chipping hammer. The tool has an impacting unit which has at least one impacting pin and a guide unit which is provided for guiding the impacting pin. It is proposed that the guide unit is formed from at least two different materials.
