A detachable battery pack is connectable to hand-held power tools, such as spiral cutting tools, in which cuts are made by positioning the axis of the cutting tool motor housing perpendicular to a workpiece surface, and moving a cutting tool bit through the workpiece in a direction perpendicular to the axis of the bit to remove material from the workpiece. The battery pack allows the cutting tool to be utilized without an electric cord and without the need of a power source near-by, thereby increasing maneuverability, safety, and range of use. The battery pack is connected to the motor housing of the power tool by being received by a receptacle. The receptacle is preferably formed to include one or more storage compartments therein, accessible through apertures in the receptacle for storage of additional cutting tool bits. A sliding door on the receptacle may be provided to allow access to the storage compartments, and to close the compartments to secure items stored therein during operation of the cutting tool. The receptacle extends outwardly beyond the motor housing over a handle so that the weight of the battery pack is centered over the handle.
