Pro-Tip: Diamond grit saws perform best when kept cool. When drilling into hard tile or stone, use a spray bottle to apply water to the cut continuously. If you are drilling vertically, you can create a small "dam" of putty around the drill site to hold a pool of water, which will significantly extend the life of the diamond coating.
