<p>The invention relates to a drilling/clamping device including a base body which can be extracted from the shaft or rod, provided at one end with a drilling head actuated by means of an electric motor housed inside the base body. The base body also includes means for coupling to the shaft or rod, provided with means for actuating an electrical contactor element in order to actuate the electric motor. In addition, a rising/falling pivoted connection is provided between the coupling means and the base body, such that, when pressure is applied to the rod or shank the coupling means move axially and abut against the contactor element associated with the electric motor, thereby starting the electric motor.</p> |
