The expanding internal chaser is worth adding to the thread saving arsenal, just insert to the bottom of the thread, expand and unwind. Very handy for cleaning up pulled threads in blind holes prior to fitting longer studs. Just using a tap quite often over threads, these things clean up the existing so even if you need to thread deeper you are indexed off the original.
