A simple analytical model of bit whirl is presented. The model takes into account the history-dependent boundary conditions at the bit-rock interface. We show that the geometry of the bit can be lumped into only three parameters. Depending on the value of these parameters the system can be stable or undergo forward or backward whirl.
