Now that the pilot hole has been cut it is possible to drill the main (large) hole. Attach the appropriate diamond core and ensure that there is a constant supply of cold water (see water cooling information in the previous sections of this article). Diamond cores that are larger than 13mm will require an adapter with pilot pin that locates into the pilot hole that has been cut previously to ensure the perfect hole will be made. Starting the drill vertically begin to drill in a circular motion with sufficient pressure until the tone of the drill changes.
The Armeg PTC Carbide drill bit range comprises of excellent porcelain tile drill bits that are capable of cutting 15-25 holes in grade 5 porcelain or 50+ in lesser grades of porcelain. These carbide drill bits boast non-slip start-up thanks to diamond-ground tip geometry. The Armeg PTC Soft Tile drill bit range is ideal for drilling softer tiles such as ceramics and travertine. They feature point-ground tips to help reduce slippage and wander. Armeg Tile Drilling Accessories for use with Armeg PTC drill bits include: water feed pump kit water feed adapters water feed clamp & drive/piloting guides to ensure non-slip start-up with small diameter diamond cores.
Identifying the Size of Hole to be Drilled. The first step is to correctly identify the size of hole to be drilled. This is very important as the diameter of the hole to be cut dictates the method that you will use to drill into the tile. The majority of holes that are 10mm and under in diameter will be drilled with the tile already fixed to the wall. Conversely the majority of holes over 10mm in diameter will be drilled into the tile before the tile has been fixed. When drilling holes that are 13mm or larger in diameter make sure that the tile to be drilled is placed in a tray that will collect the waste water that is produced.
