Machine tool

The invention relates to a machine tool， in particular a miter saw and / or miter saw， with at least one swivel arm (12)， with at least one drive unit (14) arranged on the swivel arm (12)， with at least two electrically storable energy storage units (16， 18)， in particular battery packs， for energy supply to the drive unit (14) and with at least two coupling units (20， 22) for fastening the energy storage units (16， 18) on the swivel arm (12). It is proposed that the coupling units (20， 22)， viewed along a longitudinal axis (24) of the swivel arm (12)， be arranged offset on the swivel arm (12)， the longitudinal axis (24) of the swivel arm (12) being at least substantially parallel to coupling surfaces (26， 28)， in particular main extension planes， of the coupling units (20， 22).
