No, I never put down any tile but I have cut and drilled alot of concrete.
The tools I used to cut and remove concrete were mostly dry, when we were putting in new concrete or working with concrete that we intended to keep the tools were mostly wet.
As far as tips go, let the saw do the work, don't force it because you end up borking the tile and ruining the blade.
And as always, measure twice, cut once.
