Claim:
1. A drilling system for use in a drilling formation, comprising: a head assembly having a longitudinal axis, an outer surface, an inner surface, and a proximal end, the inner surface of the head assembly defining a central bore, the proximal end of the head assembly defining an opening in operative communication with the central bore; and an overshot having: wherein, upon positioning of the pivot joint element such that the end surface of the first end portion is substantially flush with the engagement surface of the proximal portion of the overshot, the longitudinal axes of the proximal and distal portions of the overshot are substantially axially aligned, wherein the inner surface of the head assembly is configured for secure engagement with the at least one latch member of the overshot when the at least one latch member is positioned in the latched position, and wherein, upon secure engagement between the at least one latch member of the overshot and the inner surface of the head assembly, the head assembly is operatively coupled to the overshot such that movement of the overshot results in a corresponding movement of the head assembly.
