Abstract
An improved two-ended reversible drill/driver tool for use with power drills. The tool having a hollow cylindrical socket that at one end has a drive shank for insertion into a chuck of a powered drill, and, at the opposite end, has a polygonally shaped opening therein for receiving a correspondingly shaped, two-ended, reversible tool assembly. This tool assembly is sized to slide within the hollow socket, and has a combined drill bit and countersink at one end, and, at the other end, a polygonally shaped opening for accepting a screw driver bit having a shank with a polygonal cross section.

A reversible drill/driver tool for use with a powered drill having a chuck comprising:
- a two-ended reversible tool assembly having an elongate holder body means for holding at one end thereof a removable bit for drilling a pilot hole and countersink, and for holding at the other end thereof a removable screwdriver bit for driving a screw;
- an elongate hollow socket open at one end and having a drive shank attached at the other end to be received by the chuck of the powered drill;
- the hollow socket, sized to accept the two-ended reversible tool assembly within the interior thereof with one end of the reversible tool assembled exposed;
- a driving means operatively connecting the tool assembly with the socket for rotating the two-ended reversible tool assembly with the socket;
- the driving means comprising the open end of the hollow socket shaped to have a polygonal interior shape and the holder body shaped to have an elongate polygonal shaped portion intermediate the ends of the holder body for mating with the polygonal interior shape of the socket;
- a releasable retaining means for releasably retaining the two-ended reversible tool assembly within the hollow socket, the releasable retaining means including a releasable ball detent means having cooperating components on the exterior of the holder and the interior of the socket;
- a sleeve means located on and moveable along the hollow socket for operating the releasable retaining means from a position where the two-ended reversible tool assembly is held within the hollow socket to a position where the two-ended reversible tool assembly may be removed from the hollow socket;
- said ball detent means comprising a circumferential groove in the elongate polygonal portion of the holder body, the hollow socket having a sidewall with a detent ball opening with which the circumferential groove is registerable, and a detent ball in the detent ball opening to project into the circumferential groove;
- and
- wherein the sleeve means includes means for manipulating the detent ball into and out of engagement with the circumferential groove.
A reversible drill/driver tool for use with a powered drill having a chuck comprising:
- a two-ended reversible tool assembly having an elongate holder body means for holding at one end thereof a removable bit for drilling a pilot hole and countersink, and for holding at the other end thereof a removable screwdriver bit for driving a screw;
- an elongate hollow socket open at one end and having a drive shank attached at the other end to be received by the chuck of the powered drill;
- the hollow socket, sized to accept the two-ended reversible tool assembly within the interior thereof with one end of the reversible tool assembled exposed;
- a driving means operatively connecting the tool assembly with the socket for rotating the two-ended reversible tool assembly with the socket;
- the driving means comprising the open end of the hollow socket shaped to have a polygonal interior shape and the holder body shaped to have an elongate polygonal shaped portion intermediate the ends of the holder body for mating with the polygonal interior shape of the socket;
- a releasable retaining means for releasably retaining the two-ended reversible tool assembly within the hollow socket;
- and
- the releasable retaining means including a releasable "C" ring detent means having cooperating components on the exterior of the holder and the interior of the socket.
