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.
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.

Leaning in ensures that the drill will not slip and wander off center as you begin to drill into the tile.
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.
