Ensure that scrap tiles or another similar material is placed under the tile that is being drilled. This will help to halt the progress of the drill once it has finished drilling through the tile. Before drilling tile ensure that you are wearing the correct safety equipment including safety glasses or goggles. Ensure that you are using a residual current device (RCD) to help prevent electric shock. Drilling Small Diameter Holes (10mm or Smaller) with Diamond Cores. Mark the center of the hole to be drilled into the tile by using a marker or a sticky drive pad.
Recommended Equipment for Drilling Porcelain Tile. High quality diamond core drill bits. Carbide pilot drill bit - only required if youre drilling large diameter holes (13mm or larger) and dont have a suitable-sized (8mm) diamond drill bit. Masonry drill bits - included with quality tile drill bits. Water cooling equipment. Electric drill Clear safety glasses / goggles.
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.
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.
