Porcelain Tile / September 7, 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.
The hardness of porcelain tiles is an advantage for more reasons than appearance. This quality makes these tiles far more scratch resistant than ceramic tiles. When tiles get scratched up you have to go to a lot of expense and trouble to get them polished out and sometimes even that isnt possible. Porcelain tiles are also more resistant to chipping. This hardy nature also makes them less slippery than ceramic tiles which makes them a better choice for safety reasons as well.
Simply start the drill in a vertical position and the sticky pad will ensure that the drill does not slip. Once you have finished drilling the tile simply peel off the sticky drive pad. 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 diamond core 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 Ensure that the drill bit is frequently withdrawn in order to stop a build up of dust.
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.
