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.
The Porcelain Enamel Institute (PEI) rating system is also a good reference when buying your porcelain tiles. In the rating system the tiles are measured according to their application. The range starts from PEI Class 1 up to PEI Class 5. When looking for the perfect porcelain tile designs for your home you can choose from a variety of designs that are glazed unglazed or through-bodied in color composition. Whatever your preference porcelain tiles are guaranteed to make your home cozy and beautiful.
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. If you have marked the tile with a marker it is best to drill into the tile using a method called leaning in. Leaning in ensures that the drill will not slip and wander off center as you begin to drill into the tile.
