An impact tool that realizes an ON-lock function with a simple mechanism and makes it possible to switch between activation and deactivation of the ON-lock function with few operation processes is provided. A hammer drill having at least two operating modes including a hammer mode in which an impact force is transmitted to a tool bit whereas a rotational force is not transmitted thereto includes: a motor as a power source; a trigger lever and an ON-lock button that are operated by an operator; a sensor that detects whether a selected operating mode is the hammer mode or not; and a controller that controls the motor based on an operation of the trigger lever and the ON-lock button. When the ON-lock button is operated while the hammer mode is selected, the controller performs ON-lock control to maintain the motor in the operating state even when the trigger lever is not operated.

An impact tool in which stop control of a motor as power source of a tool bit is changed in accordance with a predetermined condition is provided. A hammer drill having two or more operating modes including a hammer mode in which an impact force is transmitted to a tool bit whereas a rotational force s not transmitted thereto and a hammer drill mode in which at least the rotational force is transmitted to the tool bit includes a motor as a power source and a control part that performs stop control to stop the motor, and the control part performs any one of two or more of the stop controls in accordance with a predetermined condition.

A rotary hammer selectively operates in multiple modes including a first mode and a second mode. The rotary hammer includes a switch, a motor, a switch manipulation member, a locking member, and a mode detecting device. The switch manipulation member includes a body, and a protrusion that is movable between a protruding position and a retracted position. The body houses a solenoid configured to operate based on a detection result of the mode detecting device. The locking member is movable between an unlock position and a lock position where the locking member holds the switch manipulation member in an ON position by abutting the protrusion in the protruding position. The protrusion is integrated with a plunger of the solenoid. The protrusion is configured to be in the protruding position when the present mode is the first mode, and in the retracted position when the present mode is the second mode.

An electric machine tool includes a first actuating device and a second actuating device. The second actuating device is arranged at a distance from the first actuating device. The first actuating device is mechanically connected to the second actuating device by a switching connector which is configured to be loaded in tension only.

The disclosure is based on a hand-held power tool having at least one switch device which comprises at least one switching element at least for activating a power supply of a drive unit, having at least one quick-change tool holder which is provided for holding an insertion tool which is different from an insertion tool with an SDS shaft having a maximum transverse extent of 10 mm and/or having at least one accumulator interface. It is proposed that the at least one switching device comprises at least one locking unit which is provided for maintaining, at least essentially independently of an effect of an operator activation force, an active operating mode which can be activated by actuating the at least one switching element.

A power tool that includes a housing, an electric motor, an input device, a reciprocation drive assembly, a striker, an anvil, and an electronic controller is provided. The electronic controller can control the electric motor based on a state of the input device. The electronic controller can receive a first signal from the input device, the first signal indicating a first constant speed of the electric motor, and, in response to the first signal, set an operational speed of the electric motor to the first constant speed. The electronic controller can further receive a second signal from the input device, the second signal indicating a second constant speed of the electric motor that is greater than the first constant speed, and, in response to the second signal, set the operational speed of the electric motor to the second constant speed.
