How to cut 6-inch hole in porcelain tile?
Tiles will break if you do not support them underneath (close to the center) and if you apply pressure
Porcelain tiles are already very brittle by nature. And when you make a large hole in the tile, it becomes weaker.
One other tip could be about stopping every 30 seconds to clean the drilling area and cleaning the diamond hole saw rim.
If the tile breaks when you are almost past 90%, that means you have to be even slower and more gentle. Because during exit, the vibration and imbalance are the worst.
It could be a good idea to clamp the tile down. One of our customers used clamps and pieces of wood for both fixing and guiding the hole.
