The detent based clutch requires the two halves to separate by some distance, lets call that distance z. So if tapping vertically in a mill or drill press, that will require that the distance between the workpiece and the chuck or collet be forced apart by distance z. But that can't happen in a mill, and is very difficult to make happen in a drill press. So the clutch will remain engaged and you'll break a tap.
