I've never heard of Solomon using something like this. But a 'worm' or 'snake' that cuts stone comes up when discussing the ancient pyramids and other civilizations. 

The best theory on what it is, is some kind of taproot. Perhaps connect to the burning bush. 
There plants with flammable oils and vapors that only need a spark to ignite. 

Perhaps using these plants to cut stone was a slow process. Growing trees on cliff edges. 

Or, it was just a myth from witnessing trees growing over ancient ruins with roots following the form of brick work, Jumping to the conclusion that the roots are the form.
