ABSTRACT:
A tool for a power drill allows fast and convenient loading and unloading of a screw bit, drill bit, or other implement. The user preferably loads the tool with the necessary implements which are then carried with the tool. Each received implement is movable from a storage position to an in use position in drive engagement with the power drill or power screwdriver. The desired implements can rapidly be changed from one to the other, while the implements are retained on the tool.
