A hand-held power tool includes a housing in which a drive unit and an impact-mechanism unit are arranged. The hand-held power tool further includes a tool-receiver interface configured to releasably connect with a tool receiver, the tool receiver configured as a stirrer-basket receiver. A user interface is configured to set at least one of a rotary-hammer mode and a stirring mode for the hand-held power tool.

Hand-held power tool

A power tool includes a housing in which a drive unit is arranged, and a tool holder for the detachable holding of a tool insert. The tool insert is configured to be driven percussively and/or rotationally. A sensor unit is configured to detect at least one movement variable, and electronics are configured to control or regulate the power tool. The electronics have a percussion detection unit configured to determine a percussion mode based on at least one movement variable and/or a rotation detection unit configured to determine a rotation of the housing. The electronics control the drive unit based on the determined percussion mode and/or the determined rotation of the housing. The electronics have at least two parameter sets for the percussion detection unit and/or at least two parameter sets for the rotation detection unit. The electronics are configured to select one of the at least two parameter sets.

A system includes first and second power tools that each have a percussion mechanism, a motor, and a transmission. The transmission includes a striking mechanism and is configured to transfer a driving motion of the motor to an insert tool held in a tool holder. The transmission has a guide tube that is identical in some regions along a working axis and accommodates a striker. The guide tube is rotatably coupled to the motor by a first transmission unit. The striker is driven to linearly oscillate by a piston of a second transmission unit. A ratio between a diameter of the tool holder and a diameter of the guide tube is 1.8 times greater in the first power tool than in the second power tool. A striking energy of the second power tool is mechanically reduced compared to a striking energy of the first power tool.

A hand-held power tool device, in particular a hammer drill and/or chisel hammer device, includes at least one operating element and at least one locking unit. The at least one locking unit includes at least one locking element and at least one controllable actuator element. The at least one locking element can be moved from at least one storage position into at least one locking position, and vice versa, and locks the operating element in at least one operating state in the locking position. The at least one controllable actuator element influences motion of the locking element.

Hand-held power tool device

A hand-power tool includes at least one oscillation-damping device that has at least one damping spring, a damping mass, and a mechanism housing. The oscillation-damping device has at least two retaining parts that at least partly enclose the damping mass.

Hand-power tool with an oscillation-damping device

A hand-power tool includes at least one oscillation-damping device that has at least one damping spring and a damping mass. The hand-power tool also includes a drive mechanism and a mechanism housing. The mechanism housing has a housing cover which is provided for closing a chamber in which the drive mechanism lies, and the housing cover has at least one fixing mechanism that at least partially fixes the oscillation-damping device in at least one operating state.

Hand-power tool comprising an oscillation-damping device

The invention is based on a handheld power tool, having at least one vibration-cancelling device that has at least one cancellation spring and one cancellation mass. It is proposed that the cancellation mass is constructed of at least one first mass part and at least one second mass part.
