1. A hand-held tool comprising;

  • a housing;

    a gear head received within said housing;

    a motor received within said housing and having a motor shaft that is rotatingly driven by said motor;

    a tool spindle received within said housing substantially perpendicularly to said motor shaft and having one end protruding from said gear head for receiving a tool;

    a carrier element received on said housing;

    an eccentric coupling mechanism received within said housing, said eccentric coupling mechanism being coupled to said motor shaft and to said tool spindle for driving said tool spindle in an oscillatory rotating manner about a longitudinal axis thereof, said eccentric coupling mechanism comprising a coupling member being configured as a lever and being mounted pivotably on said carrier element, said coupling member being coupled to said motor shaft and to said tool spindle; and

    a mass balancing arrangement being coupled to said eccentric coupling mechanism and being configured to impart to said eccentric coupling mechanism a balancing motion opposed to an oscillatory rotary output motion of said tool spindle.
