Porcelain Tile / September 14, 2018 / Brousseau
Porcelain comes in many shapes sizes and beautiful designs. All of these characteristics seem to make porcelain the clear choice when it comes to quality durability and easy of cleaning and maintenance. In reality the truth can be vastly different. The specifications regarding porcelain tiles are never verified or tested so any manufacturer can claim that their tiles are porcelain. Tile manufacturers can claim that they are manufacturing porcelain tiles without having them tested. In many cases tiles labeled as porcelain do not have the characteristics that make them quality tiles.
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.
These methods will not keep the drill bits cool enough and will drastically shorten the life of the drill bit. Ensure that the drill is in normal mode and set the drill to between 1000 and 1500 rpm. If you have marked the tile with a marker it is best to drill into the tile using a method called leaning in. Leaning in ensures that the drill will not slip and wander off center as you begin to drill into the tile.
