Porcelain Tile / September 10, 2018 / Brousseau.
Drilling Small Diameter Holes (10mm or Smaller) with Carbide Bits. Firstly mark where the hole will be drilled on the tile using a marker. Attach a carbide drill bit to your drill. Ensure that there is a constant supply of cold water that is being directly aimed at the selected drill bit 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 in order to keep the drill bit cool and to help remove any debris that may have built up whilst drilling the tile.
In choosing your tiles do not get confused with the terms non-porcelain and ceramic tiles because although technically porcelain is a kind of ceramic ware the term ceramic tile is usually referred to as non-porcelain. These tiles are hard and non-porous and absorb very minimal water as compared to ceramic tiles which are softer and have high water absorption. Porcelain tiles are highly durable because they can resist abrasions unlike ceramic tiles that are prone to chipping and scratches.
With porcelain being one of the most popular choices of tile material available and with the trend for porcelain tile set to continue tilers have had to adapt their working methods and tools to be able to cater for the demands of their clients. Until recently a large number of tile fixers have shied away from the installation and drilling of porcelain tiles due its perceived difficulty. However drilling holes in porcelain tile is not difficult! Using the correct methods and the best tools for the job it is possible to achieve perfect cuts in a matter of seconds.
Identifying the Size of Hole to be Drilled. The first step is to correctly identify the size of hole to be drilled. This is very important as the diameter of the hole to be cut dictates the method that you will use to drill into the tile. The majority of holes that are 10mm and under in diameter will be drilled with the tile already fixed to the wall. Conversely the majority of holes over 10mm in diameter will be drilled into the tile before the tile has been fixed. When drilling holes that are 13mm or larger in diameter make sure that the tile to be drilled is placed in a tray that will collect the waste water that is produced.
