Porcelain Tile / September 14, 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.
Drilling Large Diameter Holes (13mm or Larger). In order to cut holes that are 13mm or larger in diameter it is necessary to first drill a pilot hole. The pilot hole will act as a locater for a large diamond core and will help you to drill a perfect hole in porcelain tile. Attach an 8mm carbide drill bit or 8mm diamond bit to your drill. Follow the instructions given above for either Drilling Small Diameter Holes (10mm or Smaller) with Diamond Cores or Drilling Small Diameter Holes (10mm or Smaller) with Carbide Bits depending on whether you are using diamond cores or carbide drill bits. Leave out the final step in either case as you wont be drilling a fixing hole behind the tile.
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.
