To cut a hole in a large-diameter ceramic tile, a ballerina drill is often used, even more rarely - a diamond crown and similar methods. I want to tell you how to get out of the situation when you have nothing like that at hand, except for the grinder naturally. A Bulgarian or LBM is still more common than the tool listed earlier. This is a trick that you may need in your life.
Cut a round hole in the tile with a grinder
First, we first mark the center of the circle that we will cut, and then the full radius of the circle. And you need to do it all from two sides. From the front:
From the reverse:
Now take a grinder and make cuts as close to the edges as possible inside the circlecircle.
So we do on one plane of the whole circle.
Now turn the tile 90 degrees.
And we make grinders exactly the same cuts.
Pieces in the center begin to break - this is normal.
When you reach the end of the side of the circle, all partitions will break and you will have something like a circle.
Next, grind the edges of the circle, passing along them gently with the disc of the grinder.

Turn the tile on the inside. Just grind faces.
Then, in order to bring the circle back to normal, and to remove the sharp angle that has been formed, we cut it with a nipper. Carefully bite it all over the diameter.
For finishing, go through the file.
That's it. A little simple steps and you have a perfect circle in the tile. Throughout the work, do not forget about the means of protection - goggles and gloves. When working with angle grinders, be extremely careful and cautious. There is no doubt that the method proposed by me is much more laborious than the classical methods, but I just suggest you get out of a difficult situation.
