Porcelain Tile / September 14, 2018 / Brousseau
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.
Porcelain tile and ceramic tile both start off the same being composed of more or less the same materials such as clay and quartz. After formation they are both fired to high temperatures. What spells out the difference between the ceramic white tile and porcelain tile is that the latter uses a more highly refined and purified clay making the porcelain tile denser than the other tile. This is an extremely important difference since being more dense means that porcelain tile absorbs far less moisture making it both durable and stain resistant.
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.
