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.
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.
With all of the advantages of porcelain tiling you might be wondering why some people choose ceramic tile at all. The reason has up to now been simple: Porcelain tiles are slightly more expensive. However not all costs are found on a price tag. When you really look at the overall expenses taking into account the fact that porcelain tiles are less likely to be scratched chipped or cracked that their colors stay bright that theyre easy to clean and more safe for your family it seems clear that in the long run porcelain tiles are well worth the price.
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.
