A highly efficient and effective ultrasonic nailing and drilling apparatus for various precision use, such as medical or dental surgery, comprises of a piezoelectric transducer means to give an axial thrust and a motor to give a rotation to a bit. Therefore, this ultrasonic nailing and drilling apparatus combines the best of the ultrasound nailing or drilling bit and the best of the rotational drill. The ultrasonic nailing and drilling apparatus further comprises of an elongated horn having an operative tip, wherein a bit can be fixedly attached. The operative tip can be in any form designed to for ultrasonic machines, and even can be in a similar shape as a flat screwdriver tip, as a Phillips head tip, or even as a conventional drill bit.
