Porcelain Tile / September 12, 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.
Porcelain comes in many shapes sizes and beautiful designs. All of these characteristics seem to make porcelain the clear choice when it comes to quality durability and easy of cleaning and maintenance. In reality the truth can be vastly different. The specifications regarding porcelain tiles are never verified or tested so any manufacturer can claim that their tiles are porcelain. Tile manufacturers can claim that they are manufacturing porcelain tiles without having them tested. In many cases tiles labeled as porcelain do not have the characteristics that make them quality tiles.
There are some types of porcelain tiles that are quality made and do have characteristics that are vastly superior to ceramic tiles. You should always only shop for quality name brand tiles at quality tile shops to ensure that you are truly getting a quality product. Ask many questions at the tile store and ask to see as many samples as possible before you actually purchase them. Remember that many times you will be paying a premium for porcelain as opposed to just normal ceramic tiles. In many cases especially with indoor tile installations ceramic tiles will perform just as well at a much lower price.
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 Ensure that the drill bit is frequently withdrawn in order to stop a build up of dust.
