Drilling in Tiles – Choosing the Right Drill

Drilling In Tile

Learning how to drill a hole in tile is often considered to be a tough job. In reality, it is actually not as hard as one might assume. It is true that it is a technical task, but with a little patience and the right tools, you can easily get this job done.

When dealing with ceramics, it is recommended that you use a cordless drill. It can help you get all sorts of jobs done from drilling and driving to sanding and buffing without the hassle of a cord.

Typically, a cordless drill comes with a battery so you don’t have to worry about power supply.

There are different types of cordless drills. Some drills have lithium ion batteries.

In that case you can simply keep the drill on the charger at all times so whenever you need to perform a drilling job, your drill is charged and ready.

For other types of batteries, you don’t need to charge your drill. Instead, you only charge the batteries and your drill is ready for the job.

When drilling into ceramic tiles, you need to take care of the pressure you apply on the tile.

A cordless drill is a perfect choice as it helps manage the pressure and prevents your tile from cracking. Most cordless drills have variable speed trigger. This allows you to control the speed of the drill bits, thus protecting your ceramic tiles. 

Along with a cordless drill, there are other essential elements such as specialized drill bits and knowledge of tiles which can help you effectively drill through ceramic tiles.

Know Your Tiles

Porcelain Tiles vs Ceramic Tiles

Before you learn how to drill a hole in tile, it is important to know about the type of material you are dealing with.

Although different types of tiles appear similar, they have some basic differences which can drastically affect how you go about drilling through them.

Different types of tiles have different levels of hardness.

Ceramic tiles are less hard compared to porcelain tiles.

This means you need to be more careful when drilling into ceramic tiles. Also, ceramic tiles are often glazed on one side. Thus you need to be extra cautious when drilling into ceramic tiles as the chipped glaze can damage the tile.

A Step by Step Guide on How to Drill in a Ceramic Tile

Once you are ready with your cordless drill and you know that you are dealing with ceramic tiles, you can get started with the job of drilling in ceramic tiles.

Getting Started

As you are about to get started, make sure you clean and inspect the tile. Before you start the drilling job, ensure that the tile is clean and free of any type of debris or grease.

This will also give you a chance to inspect your tile thoroughly. If there are any cracks or signs of pre-existing damage, replace the tile before you start your drilling job.

Choose the Right Drill Bit

Drilling in ceramic tiles is a specialized drilling task.

This is why it is important to use the right drill bit. You can use the following guidelines to help you choose the correct drill bit for drilling in ceramic tiles.

  • Regular twist drill bits cannot get through hard surfaces such as tiles. So use a carbide tipped glass or tile bit.
  • If you are unable to find a carbide tipped drill bit, you can also use high speed steel bits. However, these bits will wear down after a few uses.
  • If you want a larger hole in the tile, use a hole saw bit with glass or diamond tip.

Get Ready with the Safety Gear

For all drilling jobs in general, and for drilling in ceramic tiles in particular, you need to be ready with the safety gear.

Don’t forget to wear safety goggles or glasses, as these will protect your eyes in case the tile gets damaged.

Mark the Area

Glazed Ceramic Tile

Since ceramic tiles are glazed, this is a slippery surface to deal with.

To avoid slipping, we recommend that you mark the area with an X-shape. Use a paper tape, crossing at the center of where you want to drill the hole. This reduces the risk of slipping by giving extra friction when drilling the hole in ceramic tile.

Make a Pilot Hole

Before you start the actual drilling job, make a pilot hole. You can do this by placing the drill bit on the site of the hole, and lightly tapping with a hammer. Always remember to use the hammer lightly, otherwise it can damage the tile.

The Actual Drilling Job

Once you are fully prepared with your cordless drill, the right drill bits and a clean tile, it’s time to start drilling.

The key at this point is being patient. It might be very tempting to start your drill and get done with the job but an aggressive approach can overheat your drill bits along with cracking your tiles. To avoid the damage to your drill bits and tiles, take things slowly.

Start with a low speed and apply lesser pressure under you are through the first layer of glaze. You can then gradually increase the speed and pressure until you reach the desired depth of the hole.

Drilling through ceramic tiles can take up to 3-4 minutes so make sure you drill slowly. Once you drill through the tile and reach the wall, continue drilling slowly. If you wish to continue drilling beyond through the wall, you might need to change your drill bit which is more suitable for drilling in walls.

If you want to drill up to a certain depth in your tile, it is a good idea to cover your drill bit with paper tape. You can measure the depth on your drill bit, leave that portion uncovered and start drilling.

This will help you determine when to stop drilling in ceramic tile. Once you reach the point where the uncovered portion of your drill bit is in the tile, you have reached your desired depth and you can stop drilling.

Use Water throughout the Process

Drilling into ceramic tiles generates a lot of heat. Though ceramic tiles are hard, the heat generated through friction can crack the tile.

It can also damage your drill bit. To ensure that both the drill bit and the tile are safe, you can use water throughout the drilling job. Always remember that your drill bit should always feel warm. If it is hot, it is a good idea to stop and use water to cool down your drill bit before continuing.

Key Take Away

Knowing how to drill a hole in tile is a specialized skill which needs precision and patience. Ceramic tiles are much softer compared to other types of tiles such as porcelain so you need to deal with them more carefully.

Using a cordless drill is a perfect choice for such tiles. It will help you reach your desired depth with the added advantage of controlled speed and pressure, all without a cord.

Once you know the material you are drilling into and your machine, you are good to get started with the drilling job.

Always remember that you need to drill slowly and gradually to avoid damage to the tile. At the same time, you need to protect your drill bits so don’t forget to cool them down as you continue your drilling job.

Drilling in ceramic tiles will not always be perfect. Along the way, you will damage the tiles and your drill bits, but over time, you can master this job and perform it with accuracy and patience.
