Leaning in ensures that the drill will not slip and wander off center as you begin to drill into the tile.
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.
