Abstract
A spindle for drilling heads has a substantially tubular or annular shape, with a clearance that is arranged so that it is coaxial with a drilling axis, and includes a gripping member or jaws configured to grip a drilling rod, and an actuator for selectively opening or closing the gripping member or jaws and rotating around the drilling axis integrally with the gripping member or jaws. The spindle also includes a revolving joint, through which the fluid that activates the actuator flows, and which is mounted on a free end of the spindle, on the end that is not directly constrained to the drilling head.
