Porcelain Tile / August 27, 2018 / Brousseau
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.
Porcelain tiles may be classified into natural glazed and polished tiles. The natural porcelain tile normally does not undergo any further finish after it is exposed to high temperature. This type of tile may be referred to as unglazed or through body tile where the colour goes all the way through. The glazed tile is coated with liquid glass that allows the manufacturer to put in a variety of designs and play around with colours. It comes out glossy and is one of the easiest to maintain. They are highly recommended as walls or accents in bathrooms and kitchen.
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 carbide drill bit 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 Ensure that the drill bit is frequently withdrawn in order to stop a build up of dust.
