ABSTRACT:
A portable toolbox has a compartment closed by a lid, the lid being configured to mount a powered saw module to an inner face thereof such that the saw blade extends from an outer side of the lid which provides a flat sawbench. The toolbox is used with powered hand tools of the type having a power handle module incorporating rechargeable batteries and control switch for engaging a variety of multi-purpose tools having respective electric motors. A battery station receives the power handle module and an associated circuit controls and supplies power to the saw. An adaptor fixture may be employed in one configuration to provide a drill press and in another to provide a saw fence. The adaptor fixture includes a sliding carriage for mounting a powered hand drill and jaws for clamping engagement with the toolbox when used as a fence.
