A power tool includes a tool body and a coupler assembly including a couple r, an arrester, and a bit adapter. The power tool can selectively work with a screwdriver bit to serve as a power screwdriver. Or alternately, the coupler assembly is mounted to the tool body with an end of a shaft fit to an output spindle of the tool body to allow the bit adapter to be driven by the rotati on of the output spindle. The bit adapter can selectively receive and hold drill bits of different specifications and diameters for performing different drilling operations. Thus, the power tool can be selectively functioning as a power screwdriver or a power hand drill.
