ABSTRACT:
A vibrating drill/driver includes a motor for driving a spindle about the longitudinal axis thereof, a switching handle supported for rotation about a longitudinal axis thereof, a clutch mechanism for varying a working torque in dependence on rotation of the switching handle, a switching ring having a recess and capable of rotating together with the switching handle, and a switching plate having a tip for engagement in the recess. A vibrating cam mechanism is provided to be operable to undergo a slidable engagement to provide a vibration for the spindle in an axial direction thereof when the tip of the switching plate is engaged in the recess of the switching ring. With the above-described construction, the rotation of the switching handle in one direction causes the vibrating drill/driver to be set in one of a clutch mode, a vibrating mode, and a drilling mode in this order.
