A method for operating a system that includes a main machine tool, an auxiliary device, and a transmission device with a first sending and receiving device assigned to the main machine tool and a second sending and receiving device assigned to the auxiliary device includes sending a first signal that represents a connection inquiry from the first sending and receiving device to the second sending and receiving device after an actuation of an input device of the main machine tool by a user. A second signal that represents a connection response from the second sending and receiving device is sent to the first sending and receiving device after an actuation of an actuating device of the auxiliary device by the user. The method further includes activating and/or testing an emergency cutout functionality of the actuating device by the actuation of the actuating device of the auxiliary device by the user.

A system includes a power tool and a suction device that is connected to the power tool via a suction hose. The power tool is drivable into a wall or into a substrate by a negative pressure produced by the suction device. A method includes driving the power tool into the wall or into the substrate by using the negative pressure produced by the suction device that is connected to the power tool via the suction hose.

A method for detecting whether a slip clutch release event has taken place in a power tool includes determining a first speed of a gear device by a first sensor, determining a second speed of a motor by a second sensor, and determining a current value by a third sensor. The method further includes determining a state of the power tool by using the first and second speeds and the current value, determining a state of the gear device in dependence on the current value by a control device, ascertaining a state of activity of the slip clutch in dependence on the first and second speeds by the control device, and ascertaining by the control device by a combination of the state of the gear device and the state of activity of the slip clutch whether the slip clutch release event has taken place.

A method is provided, the method comprising generating a data package, by control circuitry of a power tool; generating a unique signature for the data package with a private key, wherein the private key is generated by a secure element of the power tool, and wherein the secure element is a digital key storage unit; and transmitting the signed data package to an auxiliary device for verification.

Systems and methods for data security within power tools

A system includes a core drill and an automatic feed device. The core drill has a human machine interface (HMI) for controlling the core drill and the automatic feed device. A menu navigation of the HMI is automatically controllable in dependence on an operating state of the core drill or the automatic feed device. The menu navigation includes menu pages where the menu pages are displayable in dependence on the operating state of the core drill or the automatic feed device such that the menu navigation is controllable automatically depending on the operating state of the core drill or the automatic feed device.

A core drill bitincludes a tubular shaft, a mounting platformprovided on a proximal end of the tubular shaftfor mounting the core drill bit on a power tool, and an annular cutting sectionprovided with abrasive cutting segmentsarranged at a distal end of the tubular shaft. A first transponderis provided at the distal end of the tubular shaft. A repeateris provided comprising a second transponderat the proximal end of the tubular shaft, an antennafacing the first transponder, and a wired connectionbetween the antennaand the repeater
