Now that the pilot hole has been cut it is possible to drill the main (large) hole. Attach the appropriate diamond core and ensure that there is a constant supply of cold water (see water cooling information in the previous sections of this article). Diamond cores that are larger than 13mm will require an adapter with pilot pin that locates into the pilot hole that has been cut previously to ensure the perfect hole will be made. Starting the drill vertically begin to drill in a circular motion with sufficient pressure until the tone of the drill changes.
Attach the appropriate diamond core bit to the electric drill and ensure that there is a constant supply of cold water that is being directly aimed at the diamond core i.e. by using water cooling equipment. Note regarding water cooling. It is important to ensure that there is a constant supply of cold water directed at the drill bit in order to keep the diamond core cool and to help remove any debris that may have built up whilst drilling the tile. It is not advisable to try and cool the diamond drill bit by using a hand held aspirator or drilling through a wet sponge.
The term porcelain was coined from the Italian word porcellana because of its translucent characteristic similar to the cowrie shell. Porcelain was first developed in China and was exported to Europe between the 17th and 18th century. Beautiful jars and other delicate ornaments were made from porcelain but the discovery of its base material from soft paste to hard past has made porcelain an important industrial commodity. Porcelain is resistant to high temperatures resistant to abrasions and is also non-porous which allows very minimal water absorption. Today porcelain is an important material for insulation and is popularly used for dental prosthesis and veneers. That is why porcelain tiles are excellent choices for residential and commercial finishing.
