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.
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.
It is not advisable to try and cool the drill bit by using an aspirator or drilling through a wet sponge these methods will not keep the drill bit cool enough and the drill bit will burn out. Set the electric drill to between 700 and 900 rpm. Make sure that the drill is in normal mode. Push the carbide drill bit gently into where you have marked the tile until you hear a cracking sound. Start drilling from a vertical position with sufficient pressure and dont stop until you hear a change in the tone of the drill. As soon as you hear the change in the tone begin to ease off.
There are some types of porcelain tiles that are quality made and do have characteristics that are vastly superior to ceramic tiles. You should always only shop for quality name brand tiles at quality tile shops to ensure that you are truly getting a quality product. Ask many questions at the tile store and ask to see as many samples as possible before you actually purchase them. Remember that many times you will be paying a premium for porcelain as opposed to just normal ceramic tiles. In many cases especially with indoor tile installations ceramic tiles will perform just as well at a much lower price.
