Porcelain Tile / September 10, 2018 / Brousseau.
Attach the appropriate diamond core bit to the electric drill and ensure that there is a constant supply of cold water that is being directly aimed at the diamond core i.e. by using water cooling equipment. Note regarding water cooling. It is important to ensure that there is a constant supply of cold water directed at the drill bit in order to keep the diamond core cool and to help remove any debris that may have built up whilst drilling the tile. It is not advisable to try and cool the diamond drill bit by using a hand held aspirator or drilling through a wet sponge.

There can be many quality issues regarding porcelain tiles that are sold at home improvement stores and discount tile stores. Many times these tiles are cheap imports that are vastly inferior with many quality control issues. Unwitting people thinking they are purchasing quality tiles that are superior to ceramic when in fact they are extremely cheap. These cheap tiles can present many problems in quality durability and they can be extremely difficult to clean and maintain.
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 Ensure that the drill bit is frequently withdrawn in order to stop a build up of dust.
