FIELD: process engineering.

SUBSTANCE: invention relates to driven tool with friction coupling. Claimed tool comprises the tool body, actuator arranged in the tool body and dynamic damper. The latter comprises the case to house the weight and resilient element. The tool body is made integral with the damper case. The damper case features the elongated shape extending axially along the tool working member and has one axially exposed end. The weight and resilient element are fitted via the exposed end opening into the damper case. Said resilient element is compressed by the sealing element to seal said damper case opening and retained by the retainer. The handle is arranged at the tool body so that the damper case opening is directed outward when the handle is detached from the body.

EFFECT: decreased sizes.
