How to Drill through Porcelain Tile Without Breaking it
First, get a drop sheet and lay it on the floor to collect the dust from the drilling process. Next, have a hose system or water sprayer for lubrication.
Measure the place you want to drill and mark it with an X. Use masking tape over the mark and redraw the mark. This will make it appear clearer.
Break Through the Glaze
The glazed outer surface is designed to withstand abuse and everything you throw at it. It is the hardest part to get through since you will be dealing with a sliding drill because it is smooth.
That is why we have involved a masking tape. You can also use a wood plank to support the drill.
The Drilling Process
This is where we call for patience because if you are not, you may end up with a poorly done job.
Start by drilling at a slow speed and take it slow. You can increase the speed gradually while ensuring it does not go beyond medium pressure. Apply firm and even pressure and remember not to exceed lest you will damage the tile.
As you continue the process, pause and apply water to the tip and hole for lubrication. You can also have a pair of extra hands if you do not wish to stop drilling halfway through.
After you get through to the backside of the tile, you can rest easy as it will now be a matter of drilling through the mounting surface or the wallboard.
You should rely on the mounting surface for anchoring if you are installing racks instead of the tiles because any additional pressure may crack the tile.
If you are going to get a perfect hole without all the mess involved in drilling through porcelain tile, you will need to have the correct drill bit. But how do you go about picking the perfect model?
Here are a few Considerations to have at heart.
This material is used for industrial applications. They have a sharp cutting edge and cut at high speeds. But when it comes to their use in porcelain tile, they are prone to puncturing the tile.
They are only applicable if you can drill with the least pressure.
This type of drill bit is used in everything that is not wooden which counts for our porcelain tile issue. They have their strength from their diamond coated tips. They grind into the porcelain to deliver a clean hole without risking fractures.
There are many shapes and sizes of diamond drill bits, but it comes down to two styles: сore drill bits and blunt nose drill bits.
As the name indicates, these drill bits have a core or hollow tip. The edges of the tip are lined with diamonds.
The upside of the tip is also slightly lined with the diamonds. This is to allow it to make a round hole using the edge of the tip rather than producing a hole that is the whole diameter of the tip.
They are needed for large holes as they only drill out a small portion of the desired hole. They are also regarded to be fast to get the most extensive work done in a couple of minutes.
These drill bits have a reliable tip that is completely lined with diamonds along the edges and the sides.
They drill a complete hole which makes them useful if you are drilling small holes. They usually come in sizes up to 3/8inches.
If you are decorating porcelain dishes, blunt nose drill bits are a perfect choice, but for installing vanities and towel racks, you are better off with core drill bits.
Drilling with Diamond Drill Bits
It is important that you drill slowly using diamond drill bits. This is because they tend to get hot if used at high speeds which may burn and destroy the tip.
Also, increased temperature may cause fractures and breakage to the porcelain tile.
If you are drilling and you see burn marks, yellow, black, or brown marks, it is a sure sign that you are drilling too fast or you are applying to much pressure in the drilling process.
Why do you need Lubrication?
When drilling through porcelain tile, you will need to use water as a coolant for the tip. This will prevent heat build-up which is a sure cause of fractures.
Since there will be dust produced in the drilling process, the water will form paste that will work as the required lubrication. This way, you can have a clean hole and save your drill bits for using the next time.
What about the Pressure?
Pressure is known to increase the friction rather than the drilling speed. As such, it is crucial that you go slow and do not exceed beyond a medium pressure. As we said, fractures are messy which is what we are trying to avoid.
When getting close to the end of the hole, it is also vital to apply the least pressure possible so that the other side does not crack when you finally get through to it.
Also, you do not want to use hammer drills with diamond drill bits. This is because the bit will either split or mushroom damaging it for any future work.
Professionals may get you worried when looking to acquire the right drill bits for porcelain tile. But I think we got that part covered. We have listed the Top Best Drill Bits for Porcelain Steel. As hard and brittle as porcelain tile can be, these drill bits are the right match for it.
You can now take on professional and DIY projects involving porcelain tiles and always have a clean job after that. With one of these tools, all you need to do is gather some patience, and you are good to go.
