ABSTRACT:
A means for holding a drill chuck key in operative position on a drill chuck is provided by a pair of arms that straddle the chuck and include a shape and resilience to ensure that the chuck will be brought into operative position by cam action, and thereafter, held in proper position. That is augmented by a means for detachably securing the chuck key to another part of the drill when it is not in use to adjust the chuck. That function is accomplished with a retaining element associated with the key or with the drill, and which, when associated with the drill, has a shape so that the arms by which the key is fastened to the chuck co-act in the same way with the retaining element as with the chuck.
