The rotary tool also includes a wrench assembly for adjusting the bit holder and a light source configured to emit light in a direction toward the bit holder. The wrench assembly is positioned adjacent the bit holder and is movable between a first position and a second position. The wrench assembly is coupled to the housing and disengaged from the bit holder assembly in the first position and is engaged with the bit holder assembly in the second position.
