Abstract: A machine tool, in particular a chop saw and/or miter saw, includes (i) at least one pivot arm, (ii) at least one drive unit arranged on the pivot arm, (iii) at least two energy storage units, in particular battery packs, which can be electrically connected in series, for supplying energy to the drive unit, and (iv) at least two coupling units for fastening the energy storage units to the pivot arm. The coupling units are arranged on the pivot arm at an offset to one another with respect to a longitudinal axis of the pivot arm, the longitudinal axis of the pivot arm running at least substantially parallel to coupling surfaces, in particular main extension planes, of the coupling units.
