A multifunctional shaft apparatus includes a shaft base, a spindle, a tool holder, an ultrasonic vibration assembly, a laser light source and a mirror assembly. The spindle is disposed in the shaft base. The spindle has a laser channel extending along the spindle. The tool holder is disposed on the spindle. The tool holder has a hollow passage, an inner space and a recessed portion. The hollow passage is communicated with the laser channel. An inner wall of the hollow passage has at least one through hole communicated with the inner space, and the recessed portion is disposed on a bottom surface of the tool holder. The bottom surface has a light outlet. The ultrasonic vibration assembly includes a vibration member disposed in the recessed portion. The mirror assembly is disposed in the tool holder and is configured to reflect the laser light beam generated by the laser light source.
