Porcelain Tile / August 22, 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.
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.
