Porcelain Tile / September 14, 2018 / Brousseau
Recommended Equipment for Drilling Porcelain Tile. High quality diamond core drill bits. Carbide pilot drill bit - only required if youre drilling large diameter holes (13mm or larger) and dont have a suitable-sized (8mm) diamond drill bit. Masonry drill bits - included with quality tile drill bits. Water cooling equipment. Electric drill Clear safety glasses / goggles.
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.
The hardness of porcelain tiles is an advantage for more reasons than appearance. This quality makes these tiles far more scratch resistant than ceramic tiles. When tiles get scratched up you have to go to a lot of expense and trouble to get them polished out and sometimes even that isnt possible. Porcelain tiles are also more resistant to chipping. This hardy nature also makes them less slippery than ceramic tiles which makes them a better choice for safety reasons as well.
