Abstract: A quick release attachment tool where the rotary tool has a housing which encloses a motor with the housing having a central axis, a non-operational end portion and an operational end portion. A nose portion is formed at the operational end portion, and the nose portion has an outer annular groove disposed generally perpendicularly to the axis. The nose portion also has a non-circular element at the outer end thereof coaxial with the central axis. A rotatable shaft is connected to the motor and located along the central axis. The attachment tool includes a central cavity, an attachment end portion and a working end portion. A non-circular mating element is formed in the central cavity that matingly engages the non-circular element of the rotary tool. There is also a biased connection element provided on the attachment tool, which faces the central cavity. This biased connection element engages the annular groove of the nose portion when the attachment tool is fitted onto the rotary tool.
