How to Drill Through Ceramic Tile? 

Drilling thru ceramic tile can be tricky, especially when it’s a hard-glazed surface. It can take a while for the drill to penetrate the tile and it’s important to work slowly so that you don’t damage the surface behind the tile.

It’s a good idea to use the correct size drill bit for the job. If you’re not sure, check the manufacturer’s instructions. It’s also a good idea to lubricate the drill bit with water or cutting oil every 15 to 30 seconds, so it doesn’t burn out. 

Before you start drilling, mark the area with a pencil so that you know where you’re going. This will help you to avoid accidentally driving the drill bit into the wrong spot. You can also cover the area with masking tape to make it less likely for the drill to slip on the surface. 

Once you’ve marked the area, set the drill to low speed and start slow. You don’t want to overheat the tile and create vibrations that could damage it. 

Begin by drilling a small pilot hole. This will allow you to get the right size drill bit without damaging the ceramic tile in the process. It’ll also let you know if you need to adjust the drill bit’s angle to penetrate the tile more deeply. 

When you’re ready to drill through the whole tile, use a carbide-tipped masonry drill bit and set the tool to the lowest speed possible. Apply modest pressure as you go, working slowly to avoid splitting the ceramic. 

You’ll need to hold the drill firmly at all times, as a sudden movement or jerk of the drill can cause the tile to crack. It’s better to shave off a little of the tip than to drill through it completely. 

As with any DIY project, it’s best to make a plan and work according to it. Having a clear and accurate plan will save you time and money in the long run. 

For example, if you’re installing a towel bar, it’s important to know where the hole is going before you start drilling. If you don’t, you may end up with a lopsided bar or an awkwardly positioned one. 

Another thing to remember is that if you’re using a drill/driver, under no circumstances should you try to use it as a hammer drill. This can be very dangerous, as it could cause the wall to shift and your hand or arm to become entangled in the drill bit. 

To ensure your safety, wear gloves, a face shield, and a pair of goggles. It’s also a good idea if you’re using a hammer drill to set it to a low speed and start at the base of the hole. 

Once you’ve determined where to drill, use a spirit level to ensure its level. You can also put a drill guide on the surface of the tile to increase accuracy. 

After you’ve drilled all of the holes, it’s a good idea to remove the masking tape and clean up any excess debris from the hole. Then you can put the new fixture in place.
