Abstract
A new drill bit adapter for permitting use of drill bits which do not fit on a drill chuck which is provided with an electric drill. The inventive device includes an adapter chuck having a chuck body and an adapter shaft extending from an end of the chuck body. The shaft is sized for being retained by the drill chuck on the electric drill. The opposite end of the chuck body retains drill bits of a size which cannot be retained by the drill chuck. The drill bits are retained by a key operated retaining system, or by a hand tightened system, both of which are conventional.
