ABSTRACT:
A drilling tool consists of a drill and a tubular shaped receiving part fitted onto the trailing end of the drill. The outer surface of the receiving part is shaped to fit into the chuck or retainer of a drilling device which rotates the drill. The inner surface of the receiving part and the juxtaposed surface on the trailing end of the drill are in locking engagement, however, under certain torque conditions the locking engagement will be released so that the receiving part can rotate relative to the drill. Preferably, the locking engagement is established by deflectable projections formed on at least one of the receiving part and the drill which seat into recesses formed on the juxtaposed surface of the other. Passageways are provided between the trailing end of the drill and the receiving part.
