Introduction: Drilling Holes in Hard Porcelain Tiles With Diamond Drill Bits Holesaws Granite and Marble
Do you need to cut holes into very hard materials like porcelain tile, granite and marble? We can show you how to use diamond drilling kits made for the construction industry and used by professional installers, tilers, plumbers, builders, electricians and commercial shop fitters.
Step 1: Locate the Area of the Tile to Be Drilled With the Diamond Holesaw
Find the area on the tile where you are going to drill the hole with the diamond tile drill.
Step 2: Locating the Non-slip Guide Plate Onto the Tile Ready for the Tile Drill
Place the anti-slip guide plate into the correct area on the tile ready to accept the diamond holesaw or tile drill.
The more you push against the plate the tighter it grips the porcelain tile, or granite, marble, glass, mirror, or other hard stone material.
Step 3: Slot the Drill Into the Guide Plate Ready to Form the Hole in the Tile or Marble
Place the diamond crown or holesaw into the correct size hole of the drill plate and press the drill bit up against the porcelain ceramic tile or other hard material lik granite or marble.
If you have slightly wet the drill bit first by dipping it into water then this helps to cool it.
Slowly drill for between five and ten seconds but no more. You do not want to build heat into the holesaw.
Step 4: Remove the Drill to Expose a Small Pit Into the Tile
If you remove the drill and the anti-slip guide plate from the wall you will see the porcelain tile now has a small pit sunk into its mass. This will also be the same for marble tiles, granite worktops, travertine, slate, pottery and many other hard materials.
At this point you can discard the guide plate (drill plate) because it is no longer required.
The diamond holesaw will sit back easily into the ring and no pilot drill is required to hold everything in place.
Step 5: Place the Diamond Drill Back Into the Porcelain Tile to Drill Hole
The drill bit will slip back into the porcelain tile and lock into place without sliping.
It is very safe to drill the hole into the tile without the need of the guide plate.
Hard stone tiles including granite, marble, travertine and porcelain are very dense and so of course heat will begin to build up quickly as the diamonds grind away at the surface.
You must control the heat build up of the tile drill
Step 6: Add a Wet Sponge to Cool the Tile Drill As You Work the Stone Porcelain
You will need a small wet sponge about the size of a bar of soap and soaked in water. Using a sponge to cool the diamond drill bits will prevent early wearing of the tile drill as you bore a hole into the porcelain tiles.
Please note diamond drills are not like carbide drills. Carbide drill bits go blunt the second they overheat so must always be kept cool as you drill.
In contrast a diamond holesaw is very forgiving and if allowed to cool it will go on to grind holes into tiles.
But a word of caution: Please treat diamond holesaws with respect. Drill slowly, avoid heat and pressure to increase the lifespan.
This of the holesaw as a diamond grinder on the porcelain tile rather than a drill bit in the conventional sense. The tile drill is scraping away at the hard stone material and needs a little love and care !
Step 7: Holding the Wet Sponge UNDER the Drill Will Cool a Diamond Tile Drill
Hold the wet sponge UNDER the drill bit to cool the diamonds and you drill the hole into the very hard porcelain tile.
There are two reasons:
1) The sponge will actually prevent the water from pouring down the wall and onto the floor. Many bathrooms and kitchens are still in construction at this stage so not yet water tight. Introducing a jet of water via a water pump and an arbour can flood an area. In contrast the wet sponge only contains enough water to cool the drill and not to flood the project.
2) The wet sponge acts a catching device for the dust and spoil emitted from the stone tile. Fine particals of stone are being ground from the porcelain, ceramic or granite material. By holding the sponge UNDER the hole everything that comes out as waste can be caught.
Return the wet sponge to the bucket and rinse out. All the material from the tile drill will be contained and easy to get rid of
HOW EASY !
Step 8: Final Result. After 3mins a Perfect Hole Is Drilled Into a Porcelain Tile
After about 3 minutes of drilling into a 9mm a 11mm or even a 12mm very hard stone porcelain tile the diamond holesaw will have let you drill a perfect chip free hole into the material,
Because the diamonds are gentle they will slowly ebb away at the stone so no chips or breaks.
This is fantastic for tiles pre-fitted. A worry for installers can be breaking bathoom tiles when installed because of the time and cost involved in fitting them, removing them and replacing them.
Plus the customer is not too pleased.
Step 9: Final Thoughts to Drilling Hard Porcelain Tiles With Diamond Drills Holesaws
Diamond tile drills give neat elegant results to drilling very hard stone, granite, marble, porcelain, travertine tiles or materials either fitted or unfitted into kitchens and bathrooms.
They also work well in commercial areas like airports, bars, shops, restaurants, public plaes.
The joy of using this method is that it is quick, safe, easy and does no harm.
For example if you look at the example below the holesaw took a neat plug out of a tile. Because there is no centre pilot in the middle it didnt go deeper to hit or pierce any hidden pipework.
So thats a safe way to drill as well. Flooding bathrooms is messy and expensive.
