Abstract:

A power tool includes a housing having a large diameter rear portion and a narrow diameter nosepiece. An end effector is rotatably coupled to the housing. A holder with a substantially annular holder body is received over the nosepiece and non-rotatably coupled to the housing. A substantially annular cover having at least one transparent surface, and an internal annular groove, is received at least partially inside the holder body, and non-rotatably and axially fixed with respect to the holder. A substantially annular printed circuit board is received at least partially inside the annular groove in the cover, and non-rotatably and axially fixed with respect to the cover. A plurality of lighting elements is operatively connected to the printed circuit board and radially disposed about the printed circuit board. The lighting elements are aligned with the at least one transparent surface so as to illuminate a workpiece.
