Abstract: A breaker tool has a chassis carrying a motor, an impact mechanism operating in a certain working direction, an enclosure rigidly connected to the chassis and surrounding at least the motor, and a handle device including two handles protruding from opposite sides of the enclosure and are vibration damped relative to the chassis via swing arms, where the swing arms are arranged to accomplish a flexible parallel movement providing coupling between the chassis and the handle device. The handle device includes a bridge to which the handles are secured. The swing arms are pivotally connected to the bridge via first pivots and to the chassis via second pivots, where at least one of the first and second pivots is a torsion pivot that provides a limited torsion damped oscillation of the bridge relative to the chassis in a direction substantially parallel with the working direction.
