How to Drill a Hole in Ceramic Tile?

A drill is one of the most essential tools for the DIYer. It’s useful for many projects around the house, from erecting internal pillars to anchoring cabinets and creating soak away. But drilling holes through ceramic, porcelain, or glass tile can be a challenge — especially if you don’t know how to do it right.

First, make sure the area where you want to drill is completely hazard-free. For example, if you’re tiling over a shower tray, check to make sure there’s no sub-ground plumbing or electric wiring below. You’ll also need to make sure there are no gas piping, propane tanks, or other pipes buried under the floor. 

Next, adhere masking tape to the wall at the exact spot where you plan to drill. This makes it easier to accurately mark the location of the hole and prevents it from moving while you’re working. 

If you’re using a jigsaw, a small, carbide-tipped masonry bit will work just fine for drilling through standard ceramic tile. But for porcelain, you’ll need a diamond-tipped bit that can safely grind away the tile and create a clean hole. 

To start, set your drill to its lowest speed and apply moderate pressure. Don’t go too fast or you’ll overheat the masonry bit and cause vibrations that could crack the tile. 

As you drill, lubricate the tip of your bit with water or cutting oil every 15 to 30 seconds. It’s also a good idea to dampen the surface of the tile with a spray bottle to keep temperatures down. 

Once you’ve reached the correct depth for your fixture, remove the tape and withdraw the bit horizontally from the hole. Repeat this process until the hole is completely withdrawn. 

Now, it’s time to use your drill to create a hole through the tile. Then, you can install your fixture. 

Unlike wood, tile doesn’t like to be drilled. But if you’re careful, you can drill through it with ease and avoid the risk of cracking it. 

The best way to learn how to drill a hole in tile is to practice it. Take some dummies or use the tools you already own to see if you can get it right. 

Once you’ve gotten the hang of it, though, you’ll be able to drill through tile quickly and easily without a hitch. It’s the kind of thing that you may not think twice about, but it can be hard to master. 

If you’re not quite confident enough to try this method yourself, consider buying a hole cutter instead. These tools come in all shapes and sizes, and they can cut round holes in any size tile you’d like. 

But before you buy, be sure to read the instruction manual carefully and follow the manufacturer’s suggestions. Some hole cutters can be difficult to use, so it’s a good idea to test out the tool on some scrap material before committing to a purchase. 

Luckily, there are plenty of tips to help you do this safely and correctly. Just be sure to always wear safety glasses, industrial gloves, and a respiratory mask if you’re going to be exposed to silica dust.
