Identifying the Size of Hole to be Drilled. The first step is to correctly identify the size of hole to be drilled. This is very important as the diameter of the hole to be cut dictates the method that you will use to drill into the tile. The majority of holes that are 10mm and under in diameter will be drilled with the tile already fixed to the wall. Conversely the majority of holes over 10mm in diameter will be drilled into the tile before the tile has been fixed. When drilling holes that are 13mm or larger in diameter make sure that the tile to be drilled is placed in a tray that will collect the waste water that is produced.
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.
