A drilling tool includes: a drive source; a bit attachment portion to which an end bit is attachable; a power transmission portion configured to apply a motive force to the end bit attached to the bit attachment portion; an operation portion switchable between an ON-state and an OFF-state by a manual operation and configured to receive a setting operation for setting a stop condition; and a controller configured to set the stop condition based on the setting operation, and to start driving of the drive source in response to a first switching operation for switching the operation portion from the OFF-state to the ON-state. In a state where the stop condition is set, even when the operation portion is in the ON-state, the controller stops driving of the drive source in response to the stop condition being met while the drive source is being driven.

In a handheld power tool having a drive motor operable via a manual switch for driving a drive body which is associated with a mechanical percussion mechanism and coupled to a percussion member for driving an output shaft provided with a tool receptacle, and an operating mode switchover element which is designed to switch over between a normal operation and a percussion operation of the percussion mechanism and which is coupled to the drive body being associated with the drive body, an operating device is provided for operating the operating mode switchover element which is coupled to the manual switch and which is designed to enable a switchover of the operating mode switchover element between normal operation and the percussion operation of the percussion mechanism by operating the manual switch.

The invention relates to a hand-held chiselling machine tool comprising a motor and a pneumatic percussive mechanism that is driven by the motor. The user can select between at least two idling rotational speeds by means of a selector switch. In the chiselling mode, a motor control unit regulates a rotational speed of the motor to a nominal rotational speed. This nominal rotational speed cannot be set by the user, but is predetermined with regard to an optimal efficiency for said percussive mechanism. The motor control unit sets the rotational speed of the motor to the selected idling rotational speed when the percussive mechanism is idling. At least one of the selectable idling rotational speeds is greater than the nominal rotational speed.

A remote demolition robot (10) comprising a controller (17), drive means (14), an arm member (11) movably arranged on a tower (10a) rotatably arranged on a body (11b) of the remote demolition robot (10) and a remote control (22) for providing commands, that are interpreted by the controller (17) causing the controller (17) to control the operation of the remote demolition robot (10), wherein the remote control (22) comprises a first joystick (24a) and a second joystick (24b), wherein the remote control (22) is characterized in that each joystick (24) is provided with a thumb control switch (26).

A power tool includes a housing, a motor disposed in the housing, a motor controller disposed in the housing and electrically coupled to the motor, and a transmission disposed in the housing and coupled to the motor. A tool bit holder is rotatably driven by the motor via the transmission and receives a tool bit for rotatably driving threaded fasteners. A power switch and an electronic model select switch are actuatable from outside the housing and are coupled to the motor controller. The power switch controls power delivery to the motor. The electronic mode select switch is configured to select between at least a first mode of operation in which power delivery to the motor is controlled by actuation of the power switch and an electronic lock on mode in which continuous power is delivered to the motor upon a single actuation and release of the power switch.

An electric tool includes a housing, a motor, a tool interface, a control circuit, a master switch, and a protection circuit. The tool interface is configured to connect to a power supply to supply power to the motor. The master switch is disposed on a current path formed by the tool interface and the control circuit. The master switch has an on state in which electric connection between the tool interface and the control circuit is on and an off state in which the electric connection between the tool interface and the control circuit is off. The protection circuit is connected between the master switch and the control circuit and is configured to disconnect connection between the tool interface and the control circuit in response to the master switch being in the on state before the tool interface connects to the power supply.

A rotary hammer operable in a first mode in which only a hammering operation to reciprocate a tool bit along a drive axis is performed and a second mode in which the tool bit is rotationally driven about the drive axis. The rotary hammer includes a motor, a controller to control operation of the motor, a trigger moveable between an off position and an on position, a mode selection dial operable to select the first or second mode, a lock mechanism moveable between a first position and a second position, a linkage moveable between a third position and a fourth position, and a switch in communication with the controller. The switch communicates with the controller to operate the motor at full power or communicates with the controller to operate the motor at a variable speed based on the position of the trigger between the on position and the off position.

The disclosure relates to a method for operating a handheld power tool having an electric motor, the method comprising: S1 providing at least one model signal waveform that is associated with a work progress of the handheld power tool; S2 determining a signal of an operating variable of the electric motor; S3 comparing the signal of the operating variable with the model signal waveform and determining a conformity evaluation on the basis thereof; S4 identifying the work progress at least partially using the conformity evaluation; S5 executing a first routine of the handheld power tool at least partially on the basis of the work progress identified in method step S4. The disclosure also relates to a handheld power tool, in particular an impact driver, comprising an electric motor and a control unit, wherein the control unit is designed to carry out a method according to the disclosure.
