Porcelain Tile / September 13, 2018 / Brousseau
Now that the pilot hole has been cut it is possible to drill the main (large) hole. Attach the appropriate diamond core and ensure that there is a constant supply of cold water (see water cooling information in the previous sections of this article). Diamond cores that are larger than 13mm will require an adapter with pilot pin that locates into the pilot hole that has been cut previously to ensure the perfect hole will be made. Starting the drill vertically begin to drill in a circular motion with sufficient pressure until the tone of the drill changes.
Because the majority of small diameter holes will be cut into tiles already fixed to the wall it will be necessary to drill a fixing hole behind the tile. Replace the carbide drill bit with the appropriately sized masonry drill bit and set the drill to hammer mode. Use a slow speed for drilling into hard materials to ensure that the tip doesnt overheat. Ensure that the drill bit is frequently withdrawn in order to stop a build up of dust.
Some of the more common issues that cheap porcelain tiles can have include: Cheap porcelain tiles can actually be extremely porous and difficult to clean. They will absorb all types of dirt spills and contaminates. These types of porous tiles will start to show dirty spots especially in heavy use areas and in the center of the floor where people walk. Soon your floor will look ugly and these types of deeply embedded stains are extremely difficult to clean. Often times it can help to seal these porous tiles but this can be costly and time consuming especially for a product that you thought was dense and would be easy to clean and maintain.
