A herd of TARDISes (locked in Parallel Control with a lead TARDIS) can be set to travel in a closed time-like spiral through the Space-Time Vortex. Moving at a billion years a second this Time Drill can penetrate almost any temporal distortion or barrier (such as a Time Loop). It will also destroy any TARDISes involved.
