Drilling Large Holes in Thick Outdoor Ceramic Floor Tiles using a Diamond Coated Drill

This video demonstrates the wet drilling of a large hole (1.5 inch or 38 mm) in an outdoor ceramic (porcelain) tile.
The tile has a thickness of 20mm and has a very rough anti-slip surface.
The hole is drilled with a diamond coated drill set from Drilax. This set comes with a foam holder for water containment and drill fixation.

Can I ask why you were putting a hole there? Drainage of some kind maybe?

The holes are required to mount a 20mm threaded stud for fixation of a heavy construction to prevent it from crushing the tiles.
