If you are in the process of repurposing a finished pot or turning a ceramic piece into a lovely planter, then you may need to drill a hole through ceramic without breaking it. Fortunately, drilling through ceramic is not as hard as you may think. With the right tools and a few simple steps, you can drill holes with no worries and no broken pots!

If you are creating a clay pot yourself, it is best to make a hole in the leather-hard stage and eliminate the drilling step. If you have an already made piece and decide that you want to add a hole, though, following the following tips will help you through the process.

How to Drill a Hole in a Ceramic Pot

Here it is, the step by step guide that you need. Read on to learn how to drill a hole through a ceramic pot without breaking it!

Step One: Acquire Proper Tools

The first step to any project is making sure that you have the right tools for the task. Here, you will need a drill and the right drill bit. Make sure you get one that is made for glass and tile or tile and stone.

You can get a range of specialized drill bits at many home improvement stores or order them online. You do not want to use a typical wood or metal drill bit, as these will not cleanly drill through the ceramic.

You will also need a soft surface on which to place your ceramic pot. The surface could be a piece of foam, some newspaper, or a towel. Make sure you have a spray bottle filled with water, too. The water will keep the ceramic dust levels down and ensure that your drill bit does not burn up.

Safety goggles to wear as eye protection are necessary to incase the pot does break and ceramic pieces go flying. You should acquire earplugs and ear protection because drilling will be loud. It is also essential to wear a face mask because the drilling will be dispersing clay particles into the air.

Additionally, a piece or two of masking tape or painter tape can make it easier to begin the hole and hold your drill bit steady. The more layers you use, the more traction for your drill bit and the better grip you will have as you begin to drill. This is especially useful on glazed ceramic pots.

Step Two: Prepare Your Space

Ensure that you are working in a well-ventilated area with lots of room to move and light to see. Before you begin drilling, check your pot thoroughly for any cracks.

If your ceramic has already been cracked, then drilling through it is a sure way to break your pot in half. Make sure there are no weaknesses to the structure.

  1. Place your ceramic pot upside down on your foam, newspaper, or towel.
  2. Use a marker to make a mark where you want the hole to be. You can use a ruler to make sure that you get it in the exact position you desire.
  3. Make sure that you are drilling from the outside of the pot inward. Position your pot so that it will not move or slide around once you start drilling.
  4. Place a strip or more of tape on the mark to make the drilling easier.
  5. Spray the bottom of the pot with water.

Step Three: Begin to Drill

Start with very little pressure and go slow as you use the drill. You will want to use less force than you would if you were drilling through wood or metal. Let the drill bit do most of the work for you.

The slower, the better; drilling too fast or pushing with too much pressure will likely cause the ceramic to break.

Be patient and go slow. You can occasionally stop to spray more water onto the area and to check the progress. Your speed and the clay’s thickness will determine how long it takes you to make it through the pot.

When you feel like you are getting close to the end, slow down until you feel the drill bit make its way completely through.

Step Four: Wash and Enjoy

Once you have successfully drilled through the ceramic, gently pull the drill bit out of the hole. Remove the tape and wash your ceramic pot off.

You did it; admire your work! Now you can plant to your heart’s desire or do whatever it is you plan to use your ceramic pot for.

Helpful Tips

Below are some helpful tips to remember when drilling through the ceramic. Keep these in mind to make the process smooth and seamless and to keep your ceramic pot intact.

  1. Get the right drill. Having a good power drill will make all the difference. Make sure that your drill is working correctly and is fully charged. I recommend using a cordless drill if you have one, avoid using hammer drills. It is often easier to use because you can move around freely. Working on small projects is always simpler with a budget friendly cordless drill.
  2. Slower is better. Drilling a hole can take anywhere from 30 seconds to 3 minutes to drill completely through the ceramic. Make sure you take your time and do not rush the process. If you go fast, you risk breaking the ceramic or breaking your drill. It can also lead to flying debris and possibly injury.
  3. Get the proper grip. I recommend holding the drill firmly in your dominant hand and lightly applying pressure to the back of the drill with your opposite hand. Remember, keep it light.
  4. Use multiple drill bits. If you are looking to create a bigger hole than ¼ inch, I recommend using various drill bits. Start with a ⅛ inch drill bit and drill a hole. Spay your pot with water again and switch to a size bigger, a ¼ inch drill bit. Go over the same spot again. Repeat the process with a ½ inch drill bit and so on. Sizing up slowly will keep your pot from cracking or breaking as you drill your hole.
  5. Decide how many holes are proficient for your project. If the pot is small, then one drainage hole is usually sufficient. However, if you have a larger pot or it has an odd shape, then drilling a few different holes might be beneficial. If you choose to have more than one, simply repeat the process until you are satisfied.

How to Drill a Hole Through a Terra Cotta Clay Pot

Although they are both made from clay, Terra Cotta is slightly different from glazed ceramic and requires a somewhat different process for drilling through it. Both materials are made from clay, but the process for heating Terra Cotta is a little different. It is made at a lower temperature than ceramic, and it is a very porous material.

To drill a hole through a Terra Cotta pot, you first want to completely submerge the pot in a large bucket of water. Let it soak for at least an hour. For the best results, let it soak overnight so that it can fully absorb the water.

When your terracotta has been soaking and is fully saturated, it will be much easier to drill through. This is because the water acts as a coolant and a lubricant. It helps keep your drill bit from overheating.

In the steps above, we mention spraying your surface with a water bottle as you work, but you won’t have to do this with soaked terra cotta.

It also eliminates the possibility of your pot breaking or cracking while you drill. The porous Tarra Cotta material is softened when it is soaked, and the risk of chipping and cracking is reduced. When your pot is thoroughly drenched, remove it from the water and allow excess water to drip off.

Begin drilling before it has time to dry out.

Although tape is not as necessary to keep your drill bit in place with Terra Cotta as it is with glazed ceramic, it never hurts to add a piece or two before you start. Place almost no pressure on the drill when you begin. You want the only force to come from you keeping the drill steady and in place.

Terra cotta is porous and can break more easily than most glazed ceramic, so keep it very light.

If your drill bit does begin to smoke, remove the drill bit and can soak it in the pot in the water again before proceeding.

Which Drill Bits Are Best?

The best drill bit for your project will vary based on what kind of material you are drilling through, whether they are going to be used for wood, clay or hard materials like stucco, and how big you want your hole to be.


For regular metal or plastic pots, you can use a standard drill bit to drill holes. If you are drilling clay or ceramic, however, you will need something special.

For unglazed, natural clay pots, such as Terra Cotta, a carbide masonry drill bit is the way to go.

For glazed surfaces, you will want to use a glass and tile drill bit. They have a spear point head that helps them cut through very tough surfaces without as much pressure.

A carbide masonry drill bit would require too much pressure and would likely cause the pot to crack if used on glazed ceramic.


The drill bit size you need will vary depending on how big you want the drainage hole. If you’re going to create one simple drainage hole, you will probably want at least a ½ inch drill bit. 

Plants in ceramic pots

As mentioned above, you will want to start with a small hole and size up your drill bits as you go to create a bigger and bigger hole diameter. This eliminates the strain that you are putting on the ceramic at one time and can help prevent cracking.

Why Drill a Hole in a Ceramic Pot?

Ceramics are beautiful pieces made by taking mixtures of clay, earth, powders, and water and shaping them into specific bowls or forms. They are baked at high temperatures in an ultra-hot oven called a kiln, then glazed with a coating.

There are many reasons why you might want to drill through the ceramic. The most common reason is to create a pot for plants. By drilling a hole in the bottom, you allow a drain for water, and you don’t have to worry about your plants dying from root rot.

This allows your plants to stay healthy while also creating beautiful decor with your ceramic bowls.

Some of the most creative ceramic plant pots include teapots, mugs, hanging plant holders, vases, baking dishes, ceramic animal shapes, and more.

Another exciting craft you can create with a ceramic pot is a hanging light fixture. To make this, you simply drill a hole through your pot following the steps above. Instead of a small drill bit, though, you will want to use a hole saw. Hole saws are diamond coated on the top.

For a light fixture, you will want to use one that is around 1 ⅝ inches wide.

You then thread a lamp kit through the hole you drilled and screw the end onto the inside. Insert a light bulb, plug it in, and enjoy your new hanging light fixture! You can also mount it to a wall or a stand to create other types of lights and lampshades.

People often create crafts out of ceramic tiles, as well. If you are drilling through ceramic tiles, you can make ornaments, hanging mosaics, hanging pictures, decorative trays, and more. With such a wide variety of shapes and kinds of ceramics, the creative possibilities are endless.

Final Thoughts

Whether you are looking to spice up your outdoor garden with some exciting new pots or to liven up space with a ceramic light fixture, drilling a hole has never seemed more manageable. As long as you follow these simple steps and keep the helpful tips in mind, you will be drilling perfect holes in no time.
