A method for indicating whether a hand-held power tool has reached a target is disclosed. The hand-held power tool includes a drive motor and the method includes (i) activating a target reached indication mode by way of a control unit, (ii) ascertaining a shutdown reason for the drive motor, and (iii) displaying the reaching of the target by way of a display unit as a function of the shutdown reason.

Method for indicating whether a hand-held power tool has reached a target

A hand-held power tool includes a drive unit actuatable via at least one manual switch, a control unit at least for controlling the drive unit, the control unit having a control-unit housing. The power tool further includes at least one user interface having at least one operating element, and a housing that at least partially accommodates the control unit and the user interface. The hand-held power tool also includes a positioning device, the user interface being supported on the control-unit housing by use of the positioning device.

Hand-held power tool

A method for operating a hand-held power tool is disclosed, wherein the hand-held power tool includes an electric motor. The method includes carrying out a screw connection of a connecting device in a support, providing at least one signal of an operating variable of the electric motor during the screwing, evaluating the received signal of the operating variable of the electric motor, and deciding whether the screw connection has been properly carried out, the decision being at least partially based on the evaluation of the received signal of the operating variable of the electric motor. A hand-held power tool is also disclosed.

Method for operating a hand-held power tool

The disclosure relates to a method for operating a handheld power tool having an electric motor, the method comprising: Sproviding at least one model signal waveform that is associated with a work progress of the handheld power tool; Sdetermining a signal of an operating variable of the electric motor; Scomparing the signal of the operating variable with the model signal waveform and determining a conformity evaluation on the basis thereof; Sidentifying the work progress at least partially using the conformity evaluation; Sexecuting a first routine of the handheld power tool at least partially on the basis of the work progress identified in method step S. 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.

Method for operating a handheld power tool

A hand-held power-tool device is described as including at least one intermediate shaft, which is formed as a planet wheel carrier and includes a plurality of planet wheel receptacles and planet wheel bearing points situated in the circumferential direction. It is provided that the intermediate shaft includes at least one material recess at least in the area of at least one planet wheel bearing point on its outer circumference.

Hand-held power-tool device

A handheld power tool gearbox unit, including at least one planetary gear stage, which includes at least one planet carrier, at least one planetary wheel, which is rotatably supported in relation to the planet carrier, and at least one bearing unit, which is provided to rotatably support the planetary wheel in relation to the planet carrier. The planetary wheel includes a pin, which rotatably supports the bearing unit in the planet carrier.

Handheld power tool gearbox unit

A handheld power-tool device is described as including a drive unit, which includes at least one driveshaft, and at least one rotary striking mechanism, which includes at least one intermediate shaft aligned at least essentially flush with respect to the driveshaft, and at least one bearing for mounting the driveshaft. It is provided that the bearing is situated at least partially in a plane, which intersects the intermediate shaft and extends at least essentially perpendicularly with respect to the intermediate shaft.

A hand-held power-tool device including at least one drive housing, at least one striking mechanism housing, and at least one rotary striking mechanism, which includes at least one planetary gear including at least one annulus gear. It is provided that the annulus gear is clamped between the drive housing and the striking mechanism housing.

A handheld tool device includes a hammer mechanism that has at least a striker and a cam guide that drives the striker at least in a hammer-drilling mode. The striker has at least a portion of the cam guide.

Handheld tool device

A machine tool system includes at least one portable machine tool and at least one energy storage apparatus. The at least one portable machine tool includes at least one tool receptacle configured to be arrange a machining tool, and at least one receiving interface. The at least one energy storage apparatus is configured to be arranged on the at least one receiving interface of the at least one portable machine tool. At least in a state when the at least one energy storage apparatus is arranged on the at least one receiving interface, the at least one energy storage apparatus is arranged at least for the most part within a boundary region of the at least one tool receptacle.

Machine tool system

A hand tool device has a tool spindle and a hammer mechanism which includes a hammer and at least one curve guide driving the hammer at least during a hammer drilling operation. The tool spindle has at least one bearing surface on which the hammer is movably supported in at least one operating state.

Hand tool device

A hand-held power tool, in particular an electric hand tool, includes an identification module and a housing. The identification module includes a transponder having at least one data store configured to store identification information and a radio module configured to transmit the identification data. The identification module is integrated into the housing.

Hand-held power tool, in particular electric hand tool

In a tool attachment for a handheld power tool, which includes a tool housing having a fastening interface, having an attachment housing, on which a locking unit, for locking the tool attachment on the fastening interface of the handheld power tool, and a tool receptacle for accommodating an insert tool are situated, a percussion mechanism is situated in the attachment housing, which is configured to apply percussions carried out in the axial direction in relation to the tool receptacle to an insert tool, which is situated in the tool receptacle, during percussion operation of the tool attachment, the tool receptacle being fixed in position in the attachment housing in a non-rotating way at least during percussion operation.
