ABSTRACT:
A mounting chuck for attachment to a drill having a rotatable collar on a main chuck portion. The main chuck portion includes a cavity receiving therein a tool mount having a tool removably secured therein at either or both ends thereof. The mount conforms to the cavity and the collar encircles both the cavity and the mount to selectively either retain the mount in fixed position on the chuck portion or allow the mount to be removed therefrom. The chuck portion includes a hollow axially extending chamber so that one of the tools on the mount may extend into the chamber while the other tool on the mount extends out from the chuck portion in an operative position. In this manner, the tools on the mount may differ and either tool may be quickly and easily selected.
