Abstract

Power tools (1) may include an electric motor (11) disposed within a housing (5). A lighting device (20) may be mounted on the housing and may serve to illuminate the area around a tool bit and/or a portion of a workpiece (W) that will be machined by the tool bit. An electric light (23) may be connected to a power source circuit (11a) via an electric line that includes electric wires (25). In order to facilitate the wiring operation, a wire guide (22, 122) preferably supports or retains at least a portion of the electric line. The wire guide may be mounted on the housing such that the wire guide extends along an inner surface or an outer surface of the housing. In the alternative, the electric line may be disposed within a recess (31) defined within an inner surface or an outer surface of the housing. In either case, the electrical line can be easily wired or installed and the electric line preferably does not interfere with machining operations during operation of the power tool.
