According to a second embodiment the drive-side element of the stroke gear is designed such, that in a complete revolution of the drive-side element of the stroke gear the tool-holding device runs through more than a double stroke. According to another embodiment the drive-side element of the stroke gear is disposed concentrically around an axis of rotation of the driveshaft.
