Answers:    I tile every morning of my life, and hope you hold extra tile pieces. As one answer states a diag. Grinder and a diamond blade. I go through a couple a week, but for sure you can't pull a drizzling saw to the wall.

I'll assume not, but might you make the cuts on grout lines?

Also, I'm wondering in the region of even 5/8 drywall as a substrate for tile work?

You might also use a Dremel with a proper bit for the intensely corners, but with safekeeping the Di. Grinder will suffice, You probably can expect cutting into the dry wall as in good health.

I'm newly purchasing a FEIN Multi tool, that I'll use exclusively for installed tile cutting, especially grout.

You involve a 4 1/2" angle grinder with a diamond blade contained by it.
