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.
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.
