Porcelain Tile / September 13, 2018 / Brousseau
There can be many quality issues regarding porcelain tiles that are sold at home improvement stores and discount tile stores. Many times these tiles are cheap imports that are vastly inferior with many quality control issues. Unwitting people thinking they are purchasing quality tiles that are superior to ceramic when in fact they are extremely cheap. These cheap tiles can present many problems in quality durability and they can be extremely difficult to clean and maintain.
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.
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.
