Pro-Tip: To extend the life of your diamond hole saw, always use water to cool the bit. If drilling vertically into floor tile, create a small dam around the hole location using plumber's putty and fill it with water. This keeps the diamond grit submerged and cool throughout the entire cut, preventing heat damage and extending tool life.
