A power tool system includes a tool body with a motor having an output member that drives an accessory. The output member defines an output member axis. An end effector is coupled for rotation with the output member relative to the tool body. The end effector is configured to retain the accessory. A light source is disposed on the end effector. A consumable tool, such as a holesaw, is removably attachable to the end effector, and has an illumination opening configured to be substantially aligned with the light source. The holesaw may have a generally cylindrical side wall and a base wall that defines a central opening for receiving an arbor, an aperture spaced radially outward by a first distance for receiving a projection on an arbor and an illumination opening spaced radially a second greater distance.
