Percussive augmenter of rotary drills for operating as a rotary-hammer drill

A percussive augmenter bit, comprising:

• a connection shaft configured for mounting the percussive augmenter bit onto a rotary drill, wherein the percussive augmenter bit is rotated by the rotary drill;
• an actuator that percussively drives the percussive augmenter bit;
• and
• an electric power transmission mechanism that provides power to the actuator while being rotated by the rotary drill;
• wherein hammering action from the actuator and rotation from the rotary drill are applied directly to material being drilled;
• and
• wherein the actuator comprises a piezoelectric actuator.
