A tool that includes an interchangeable drive head and a split gear body for transmitting torque to the drive head. The compact nature of the split gear body allows for an automatic power means, for example, an electric or air motor, to supply torque through the split gear body into the interchangeable drive head. Further, the interchangeable drive head includes a gear that is positioned around a receiving portion for receiving a head of a workpiece, so that the interchangeable drive head itself is part of the gear assembly. The above structure allows for a compact design while still allowing for an automatic power means to transmit the torque to the workpiece. |
