Provided is an apparatus for testing a resonance enhanced rotary drilling module, which apparatus comprises: (i) a resonance enhanced rotary drilling module comprising an oscillator; (ii) a fixed frame for fixing the apparatus to a base surface; (iii) a movable frame for moving the rotary drilling module in an axial direction relative to a sample; (iv) a means for generating relative rotary motion between the drilling module and a sample; and (v) a torsion restraint unit for reducing the torsional loading on the oscillator. |
