A power tool with a chuck and a tool body having a housing, a motor received in the housing, a light array mounted to the housing, and an output spindle extending through the light array and which is rotationally driven by the motor. The chuck has a chuck body, a plurality of jaws, and an outer sleeve. A rear end of the chuck body is rotatably mounted on the output spindle. The chuck body has a plurality of jaw apertures and a plurality of light holes. The jaw apertures and the light holes extend through a front surface of the chuck body. Each of the jaws is received in a corresponding one of the jaw apertures. The outer sleeve is disposed about the jaws and the chuck body. Light emanating from the light array is transmitted through the light holes to illuminate a zone in front of the chuck body.
