  • using guide plate

In the market, you can find guide plate. This kind of guide plate is non-slip. And there are different diameters hole. You have to just push this plate against the porcelain tile. It will get tighter to the wall automatically.

Choose where to drill. Then hold your guide plate. There are smaller to larger holes. Larger holes are for the hole saw. Choose the right size. Now, slightly wet the drill bit into the water. This will help to cool the drill. Now slowly drill for five to ten seconds. This will be enough to make the slot. Remove the drill machine. There will be a small pit over the drill section. You can now start the drilling.

As with fast speed, the drill machine will get overheat and make vibration. But don’t lose the grip. Slowly increase the pressure over the drill point. Don’t increase at a time. Else this will turn into breaking the wall or cracking.


Always cool the drill bit

Don’t forget that your drill bit gets heated. It happens as you do the drilling for a long time. So, it is important to prevent the drill bit from overheating.

You can spray water maintaining a certain time. It will help to cool down the bit. But on the other side, it can affect negatively. Water can go into the motor. This can damage the drill machine.

So there is another way that you can follow without any risk. You can use a wet sponge. This will help you to cool the bit always. There are other benefits too. When to drill, there will be a lot of waste. So, those will be caught by this sponge as well. You have to hold the wet sponge below the drill bit. This is the proper and exact way to cool down the bit.
