Abstract
A power tool including a end effector rotatable with respect to the housing, a collar rotatable with respect to the housing, a printed circuit board (PCB) rotatably fixed with respect to the housing, and a light element operatively connected to the PCB and adjacent to the end effector and in a recess of the collar and located to illuminate a workpiece machined by the power tool. A method of providing light for a workpiece being machined by a power tool including locating lighting elements around a spindle of a power tool, aligning the lighting elements to shine light on a workpiece being machined by the power tool, operatively connecting the lighting elements to a PCB, containing and supporting the PCB with a guide, supporting wires configured to provide power to the PCB with the guide, locating the lighting elements, PCB and guide in a rotatable collar, and preventing the lighting elements, PCB and guide from rotating when the collar rotates.
