Abstract: A device for measuring the torque or force exerted by a drilling machine during a rotation, driving or lifting of a tool. The measuring device includes an engaging device with a drilling battery or with a shaft of at least a drilling equipment or rotary of the machine the engaging device is susceptible of symmetrically or axial-symmetrically locking the drilling battery or the shaft preventing the rotation and/or the axial displacement in a position in correspondence to the tool. The engaging device is associated with at least a transducer for the detection of at least a maximum torque or of at least a maximum force exerted by the machine; and the measuring device is fixedly constrained to the drilling battery or to the shaft.
