Abstract: 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.

Abstract: 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.
