Porcelain Tile / August 26, 2018 / Brousseau.
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.
When the shipment arrives they can look vastly different from the ones that were originally ordered. Often the colors and textures can look different from the sample. Other times there may be surface scratches or other imperfections that make them look ugly. Once the shipment arrives at your door it can be extremely difficult to return them and ship them back. Other times the quality control issues are not noticed until the tiles are installed and then the manufacturer will never accept returns on already installed tiles no mater what types of problems they have.
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.
How to lean in... To lean in simply start the drill at an angle as soon as the drill bit has started to cut the tile slowly bring the drill into a vertical position. Ensure that sufficient pressure is being applied (tile dust should be evident in cooling water) and rotate slowly until you have cut the perfect hole. As you finish the hole you will notice that the tone of the drill will change. Using sticky drive pads. If you use a sticky drive pad it is unnecessary to use the leaning in method.
