ABSTRACT:
A reversible drill and drive tool for performing a series of similar drill and drive operations. The tool consists of an elongated cylindrical housing having at its rear end a shaft of reduced diameter for insertion into the chuck of a power drill and a front and bifurcated to form two arms with parallel flat interior surfaces and a generally cylindrical tool-holding member having at each end an axially recessed cylindrical socket of reduced diameter adapted to receive a drilling tool at one end and a driving tool at its other end. Each arm of the housing contains an identical elongated slot running parallel to the axis of the housing, and the tool-holding member being slidably and pivotably pinned into the housing by a pin whose outer ends lie within the elongated slots in the arms of the housing. The tool-holding member also has a pair of identical and parallel flat sides which lie parallel to the flat interior surfaces of the arms of the housing and the housing has a third elongated slot which lies at 90.degree. to the first two slots and is positioned to provide clearance for the drilling tool projecting from one end of the tool-holding member as the tool-holding member is pivotably rotated about its pin, and the housing also has a plurality of recesses designed to accommodate portions of the tool-holding member and its tools when the tool holder is in its operating position.
