Abstract (en)
[origin: EP2230051A1] The tool (1) has a drive comprising a drive motor (3), a wobbling finger (6) and a connecting rod (8), which are designed to move a stroke-generating element (5) i.e. piston, in a reciprocating fashion along a translation axis (22). A counterweight (12) i.e. counter vibration device, is connected to the drive to partially compensate forces indirectly caused by the reciprocating motion. The counterweight is supported coaxial or parallel to the translation axis in a reciprocating movable manner. The counter weight is supported in a bush (20), which is designed as a hollow cylinder.
