Cut Tile With A Grinder | Family Handyman
In this story, we'll show you how to use an angle grinder with a diamond blade to cut perfect circles and squares in even the toughest tile. You can buy a 4-in. or 4-1/2-in. grinder for around $50 and a dry-cut diamond blade (below) to fit it starting at $20. In general, more expensive blades will last longer.
