Most toilet pans and bidets require heavy duty fixings like anchor bolts or screws to hold them onto a tiled floor. How do you drill the tiles so that you can fix that pan down securely. 365Drills show the PORSADRILL diamond tile drilling system cutting PLUGS out of tiles so that the fixing can pass right though the tile. The point of this is that by missing the tile there is a less likely change of breaking the tile. By drilling a plug out of a tile you can have easy access to the hard concrete floor below or the wooden substructure. On a concrete floor if you have to drill it out then by having a wide hole in the tile means you wont hit it / split it with the hammer action drill. The tequnique also works if you have to put items down on areas like airport terminal tiled floors (example cash point machines) on shop floors. You name it if the floor is tiled then cut a plug out rather than a small hole.
