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.
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.
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 Ensure that the drill bit is frequently withdrawn in order to stop a build up of dust.
