However, it is also contemplated that the direction of rotation 26a, 28a may be automatically switchable during a cutting operation, for example, by way of the control and/or regulation unit.
The tool 10a comprises a lighting unit 30a to illuminate a cutting area 40a of the cutting unit 12a. The lighting unit 30a here comprises, by way of example, a lighting element 58a. The lighting element 58a is as an LED for example here, in particular an annular LED. Alternatively, it is contemplated that the lighting unit 30a comprises a plurality of lighting elements 58a. The lighting unit 30a is arranged on a side facing the alignment axis 38a of the base body unit 16a, in particular the tool head 46a, preferably on the inner side 50a.
The tool 10a comprises a removable cable stop 32a (cf.
Alternatively, it is conceivable that the stripping step 64a takes place after the round cutting step 66a, in particular wherein 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 stop 32a.
The alignment axis 38b is at least substantially perpendicular to a main extension axis of the manual machine tool 36b. A “main extension axis” of an object can be understood in particular as an axis that extends parallel to a longest edge of a smallest geometric cuboid that just completely encloses the object, and in particular extends through the center of the cuboid. The term “substantially perpendicular” can be understood to mean an alignment of a direction relative to a reference direction, wherein, in particular viewed in a projection plane, the direction and the reference direction enclose an angle of 90° and the angle has a maximum deviation of in particular less than 8°, advantageously less than 5°, and particularly advantageously less than 2°.
The plane is disposed at least substantially perpendicular to the main extension axis of the manual machine tool 36b. The tool 10b is disposed in extension of the manual machine tool 36b with respect to the main extension axis of the manual machine tool 36b.
