ABSTRACT:
A reversible drill/driver tool includes an elongated socket having a bifurcated part defining a tool-receiving space to receive a two-ended tool that includes first and second driving bits and a rod having two opposite ends connected respectively to the first and second driving bits, and pivoted to the bifurcated part so as to be rotatable relative to the socket and so as to dispose a selected one of the first and second driving bits outwardly of the space. A positioning member is slidable on the socket to position the rod at a desired position.
