1. An upper drill tool comprising:
central chuck having a chuck base and at least one chuck, the at least one chuck structurally configured to retain a drill bit;
an upper component coupled to the central chuck, the upper component having a lower stop surface;
a lower component having:
a central body with an outer surface, the outer surface having threads disposed thereon, the central body having a drill bit bore corresponding to each of the at least one chuck, to facilitate the passage of the drill bit therethrough, the bore terminating at a lower end of the central body; and
an outer ring having an inner surface, with the inner surface having outer ring threads positioned thereon, the outer ring threads matingly engaging the threads of the central body, the outer ring having an upper stop interfaceable with the lower stop surface of the upper component; and
a coupling assembly having a slidable coupling having a first end attached to the lower component and a second end attached to one of the central chuck and the upper component, the slidable coupling facilitating the slidable movement of the lower component from a first orientation wherein the upper stop is spaced apart from the lower stop surface and a second orientation wherein the upper stop is in abutting engagement with the lower stop surface, with the first orientation and the second orientation defining a stroke,
wherein the coupling assembly precludes rotation of the central body relative to the chuck base.
