Porcelain Tile / September 3, 2018 / Brousseau
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 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.
How to lean in... To lean in simply start the drill at an angle as soon as the drill bit has started to cut the tile slowly bring the drill into a vertical position. Ensure that sufficient pressure is being applied (tile dust should be evident in cooling water) and rotate slowly until you have cut the perfect hole. As you finish the hole you will notice that the tone of the drill will change. Using sticky drive pads. If you use a sticky drive pad it is unnecessary to use the leaning in method.
