    Based on this model, it is demonstrated that drill bits undergo wobbling motion in drilling conditions. This model explains the lobed appearance of bottom hole patterns associated with PDC bit failure in hard rock drilling. Resonance is responsible for severe bit wobbling which may damage PDC bits rapidly in hard formation drilling.
