How To Drill Porcelain Tile


If you’ve ever tried to drill into porcelain tile, you know that it can be a challenging task. Porcelain tile is notoriously difficult to drill through, but with the right tools and techniques, it is possible to get the job done. In this article, we’ll provide you with a complete guide on how to drill porcelain tile.

Understanding Porcelain Tile

Porcelain tile is a type of ceramic tile that is made by firing a mixture of clay, feldspar, kaolin, and other materials at high temperatures. This process makes the tile very hard and durable but also makes it difficult to drill through. Porcelain tile is commonly used in bathrooms, kitchens, and other areas that require a water-resistant and durable surface.

Tools You’ll Need

To drill porcelain tile, you’ll need the following tools:

  • Corded drill or cordless drill
  • Diamond-tipped drill bit
  • Masking tape
  • Spray bottle filled with water
  • Safety glasses
  • Dust mask
  • Gloves
  • Marker

How to Choose the Right Drill Bit

The key to drilling porcelain tile is to use a diamond-tipped drill bit. Diamond is the hardest material on earth and is capable of cutting through porcelain tile. When choosing a diamond-tipped drill bit, make sure it is the correct size for the hole you want to drill. You can find diamond-tipped drill bits at your local hardware store or online. There are various types of drill bits available based on the purposes such as drill bits for aluminium, and drill bits for wood.

How to Prepare the Porcelain Tile

Before you start drilling, you’ll need to prepare the porcelain tile. Start by placing a piece of masking tape over the area where you want to drill. This will help to prevent the drill bit from slipping and scratching the tile. Next, use a marker to make a small mark on the masking tape where you want to drill.

Fill a spray bottle with water and spray the area where you want to drill. This will help to keep the drill bit cool and lubricated, which will prevent it from overheating and breaking.

Drill Into Tile

Drilling through porcelain tile can be a challenging task, but it can be done successfully with the right tools and techniques. When drilling through tile, it’s important to use a drill with high torque and a diamond-tipped drill bit specifically designed for porcelain tile.

It’s also important to start with a small drill bit and gradually work your way up to the desired size. Use light pressure and let the drill bit do the work, avoiding pushing down too hard. Keep the area wet with a spray bottle to prevent overheating and to lubricate the drill bit. Use a slow speed and take breaks if the drill bit starts to overheat.

Once you’ve drilled through the tile, remove the masking tape and wipe away any dust or debris. Finally, be sure to clean up any debris or dust and take safety precautions to protect yourself from injury.

How to Clean Up After Drilling

After you’ve finished drilling, it’s important to clean up any debris or dust. Use a vacuum or dustpan to remove any loose debris from the area. Then, wipe the area with a damp cloth to remove any remaining dust or debris.

What to Do if You Break a Tile

If you accidentally break a tile while drilling, don’t panic. First, remove any remaining pieces of the broken tile. Then, use a tile repair kit to fill in the hole. Once the repair has dried, you can paint or seal the tile to match the surrounding area.


Drilling through porcelain tile may seem daunting, but with the right tools and techniques, it can be done successfully. Remember to use a diamond-tipped drill bit, keep the area wet with a spray bottle, and use light pressure. By following these tips and taking safety precautions, you can successfully drill through porcelain tile and complete your project.
