Pro-Tip: To extend the life of your diamond grit hole saw and prevent overheating, always use water as a coolant when drilling into hard tile or stone. Starting your cut at a 45-degree angle helps "score" the material and create a groove, allowing you to slowly bring the drill to a vertical position for a perfectly centered, chip-free hole.
