It is not advisable to try and cool the drill bit by using an aspirator or drilling through a wet sponge these methods will not keep the drill bit cool enough and the drill bit will burn out. Set the electric drill to between 700 and 900 rpm. Make sure that the drill is in normal mode. Push the carbide drill bit gently into where you have marked the tile until you hear a cracking sound. Start drilling from a vertical position with sufficient pressure and dont stop until you hear a change in the tone of the drill. As soon as you hear the change in the tone begin to ease off.
Some of the more common issues that cheap porcelain tiles can have include: Cheap porcelain tiles can actually be extremely porous and difficult to clean. They will absorb all types of dirt spills and contaminates. These types of porous tiles will start to show dirty spots especially in heavy use areas and in the center of the floor where people walk. Soon your floor will look ugly and these types of deeply embedded stains are extremely difficult to clean. Often times it can help to seal these porous tiles but this can be costly and time consuming especially for a product that you thought was dense and would be easy to clean and maintain.
Simply start the drill in a vertical position and the sticky pad will ensure that the drill does not slip. Once you have finished drilling the tile simply peel off the sticky drive pad. Because the majority of small diameter holes will be cut into tiles already fixed to the wall it will be necessary to drill a fixing hole behind the tile. Replace the diamond core with the appropriately sized masonry drill bit and set the drill to hammer mode. Use a slow speed for drilling into hard materials to ensure that the tip doesnt overheat. Ensure that the drill bit is frequently withdrawn in order to stop a build up of dust.
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.
