A power tool in accordance with the invention includes a housing having an internal compartment with a motor therein, a handle connected to the housing for maneuvering the power tool, a working element connected to and driven by the motor to work on a workpiece, and a removable, portable power source having a first position wherein the power source is located primarily in the internal compartment of the housing and being electrically connected to the motor to provide power to the motor for driving the working element and a second position wherein the power source is located remotely from the housing and detached electrically from the motor. A preferred embodiment of the tool also includes a lock associated with the apparatus which has a lock position that prevents the removable, portable power source from unintentionally becoming separated from the power tool, and an unlock position that enables the removable portable power source to be selectively removed from the internal compartment of the housing and separated from the power tool. A preferred embodiment of the power tool includes the use of a rechargeable, removable, portable power source and an electrical connector which allows the power tool to be powered by an alternate power source located externally of the power tool.
