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.
Drilling Large Diameter Holes (13mm or Larger). In order to cut holes that are 13mm or larger in diameter it is necessary to first drill a pilot hole. The pilot hole will act as a locater for a large diamond core and will help you to drill a perfect hole in porcelain tile. Attach an 8mm carbide drill bit or 8mm diamond bit to your drill. Follow the instructions given above for either Drilling Small Diameter Holes (10mm or Smaller) with Diamond Cores or Drilling Small Diameter Holes (10mm or Smaller) with Carbide Bits depending on whether you are using diamond cores or carbide drill bits. Leave out the final step in either case as you wont be drilling a fixing hole behind the tile.
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.
