Alternatively or additionally, it is also conceivable for a preferably further spring element 18a of the alignment unit 14a to be arranged on the alignment elements 42a on a side facing the alignment axis 38a, which spring element preferably rests against the cable in at least one operating state, in particular in a cable alignment state.

[0044] The tool 10a has a display unit 20a for displaying a setting of the alignment unit 14a. The display unit 20a can be configured as a mechanical display, an electromechanical display, an electrical display, an electronic display, or the like, or as a combination thereof. The display unit 20a is arranged here, for example, on an outer side of the base body unit 16a, in particular the tool head 46a.

[0045] A cutting angle of the cutting elements 22a is adjustable. The cutting angle can be adjusted, for example, to produce a spiral, circular, and / or longitudinal cut. The cutting angle is adjustable, in particular adjustable, with respect to the alignment axis 38a.

[0046] The tool 10a has a sensor unit 24a for detecting at least one process parameter during the stripping of the cable. The sensor unit 24a here comprises, for example, an acceleration sensor and / or a gyro sensor. The process parameter has at least one acceleration parameter. The sensor unit 24a is configured to determine a hazardous situation depending on the process parameter. For example, the sensor unit 24a is configured to detect a tilting of the cutting unit 12a and / or an unintentional rotational movement of the tool 10a depending on the process parameter, in particular the acceleration parameter.

[0047] It is conceivable that the tool 10a has a control and / or regulating unit (not shown here) for controlling and / or regulating the alignment unit 14a and / or the cutting unit 12a, in particular the drive unit of the handheld power tool 36a. It is also conceivable that the alignment unit 14a and / or the cutting unit 12a can be controlled and / or regulated by means of a control and / or regulating unit (not shown here) of the handheld power tool 36a.

[0048] It is conceivable that the control and / or regulating unit is provided to control and / or regulate the alignment unit 14a and / or the cutting unit 12a, in particular the drive unit, depending on the process parameter, preferably during a cutting process by the cutting unit 12a and / or during an alignment process by means of the alignment unit 14a. For example, it is conceivable that the control and / or regulating unit is provided to adapt a rotation rate of the cutting unit 12a, to switch off the drive unit, or the like, depending on the process parameter.

[0049] The cutting unit 12a can be operated in a soft mode. The soft mode features a soft start. The soft start is active when the cutting unit 12a begins cutting the casing. For example, the rotation rate of the cutting unit 12a in soft mode, particularly in soft start, is reduced compared to normal mode. It is conceivable that the rotation rate of the cutting unit 12a in soft start is increased continuously, preferably continuously or in stages.

[0050] The cutting unit 12a is operable in two directions of rotation 26a, 28a. The cutting unit 12a is operable in two directions of rotation 26a, 28a relative to the rotation axis 44a. The directions of rotation 26a, 28a are opposite to each other. The cutting unit 12a is configured to cut the cable sheath in both directions of rotation 26a, 28a.

[0051] The cutting unit 12a is configured to produce two different cutting paths. The cutting unit 12a is configured to produce a first cutting path in one direction of rotation 26a of the directions of rotation 26a, 28a. The cutting unit 12a is configured to produce a second cutting path in a further direction of rotation 28a of the directions of rotation 26a, 28a, preferably opposite to the direction of rotation 26a. The first cutting path is different from the second cutting path. The cutting path can in particular be a circular cut, a spiral cut, a longitudinal cut, or the like. The first cutting path is, for example, a circular cut. The second cutting path is, for example, a spiral cut.

[0052] One cutting element 22a of the two cutting elements 22a is designed and / or arranged such that a cut in the casing by the cutting element 22a can be produced by rotating the cutting unit 12a, preferably relative to the base body unit 16a and / or the cable, only in the direction of rotation 26a. Another cutting element 22a of the two cutting elements 22a is designed and / or arranged such that a cut in the casing by the further cutting element 22a can be produced by rotating the cutting unit 12a, preferably relative to the base body unit 16a and / or the cable, only in the further direction of rotation 28a. The tool 10a has an operating element (not shown here) for switching the direction of rotation 26a, 28a. The operating element is designed as a button, a lever, a rotary knob, or the like.However, it is also conceivable that the direction of rotation 26a, 28a can be automatically switched during a cutting process, for example by means of the control and / or regulating unit.

[0053] The tool 10a has a lighting unit 30a for illuminating a cutting area 40a of the cutting unit 12a. The lighting unit 30a here has, for example, a lighting element 58a. The lighting element 58a is embodied here, for example, as an LED, in particular as a ring-shaped LED. Alternatively, it is conceivable for the lighting unit 30a to have multiple lighting elements 58a. The lighting unit 30a is arranged on a side of the base body unit 16a, in particular of the tool head 46a, facing the alignment axis 38a, preferably on the inner side 50a.

[0054] The tool 10a has a removable cable end stop 32a (see Fig. 3). The cable end stop 32a is detachably attachable to the base body unit 16a, preferably to the tool head 46a. The cable end stop 32a is adjustable. It is conceivable that the cable end stop 32a has a display for reading the setting of the cable end stop 32a. A maximum stripping distance, in particular parallel to the alignment axis 38a, can be set via the cable end stop 32a.

[0055] Fig. 8 shows a schematic sequence of a method for operating the tool 10a. In one method step, in particular in a cable insertion step 60a, the cable is preferably inserted into the tool 10a, preferably the tool head 46a, up to the cutting unit 12a. In one method step, in particular in an alignment step 62a, the cable is aligned by means of the alignment unit 14a, preferably with respect to the alignment axis 38a. In one method step, in particular in a peeling step 64a, the cable is peeled off until the cable end stop 32a is reached, preferably by means of the cutting unit 12a, preferably by means of a spiral cut. A peeled-off part of the sheath is detached from the cable with a circular cut, in particular in a circular cut step 66a, preferably after the cable end stop 32a has been reached.

[0056] Alternatively, it is conceivable that the peeling step 64a takes place after the circular cutting step 66a, wherein in particular the cable, in particular in the cable insertion step 60a, is inserted into the tool 10a, preferably the tool head 46a, up to the cable end stop 32a.
