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.
When the shipment arrives they can look vastly different from the ones that were originally ordered. Often the colors and textures can look different from the sample. Other times there may be surface scratches or other imperfections that make them look ugly. Once the shipment arrives at your door it can be extremely difficult to return them and ship them back. Other times the quality control issues are not noticed until the tiles are installed and then the manufacturer will never accept returns on already installed tiles no mater what types of problems they have.
Unglazed tiles do not have a coated surface and full body porcelain tiles dont show wear anyhow due to the colour and design being throughout the entire tile. These types of tiles have a PEI rating of 0-5 meaning they can be used in any area. PEI classes are 0 through 5. The porcelain enamel institute scale is one that is used to help detect areas that tiles should be used in. The glazed tiles that have the overall 0 to 5 rating can be used anywhere from no foot traffic to industrial traffic making them ideal for use in your home.
