Abstract

The portable electric tool comprises a driving shaft (50), an eccentric (24) rotated by the driving shaft (50), a turning support (23) for an operating element (22) mounted on said eccentric (24) and a counterweight (49) to balance the eccentric (24). The eccentric (24) and the counterweight (49) constitute a single piece which is mounted on an axial extension (21) of the driving shaft (50).
