What’s the secret to doing it without breaking the tiles? Even though porcelain tiles are more difficult to drill due to their higher density, this does not preclude you from succeeding.

Following this post, you will learn how to drill porcelain tiles efficiently and without damaging them.

Is Porcelain Tile Superior?

In a mosaic, not every piece of tile is the same. There is a vast range of hardness in tiles, from adobe to marble.. However, tiles made of porcelain have unique qualities in that they are extraordinarily durable. This is because they’re so rugged; they’re comparable to stone.

Various materials are employed in the production of tiles. Sodium silicate is a critical component in porcelain tiles. Using extremely high temperatures, they are baked into a highly durable stone.

It is a ceramic substance created by human hands, and porcelain is one of the most common. But unfortunately, it’s dense, heavy, and nearly impossible to drill through.

Porcelain tiles can be coated with a glaze, which gives them a glossy appearance. Unfortunately, this tile-covered surface makes drilling difficult and incredibly slick.

Among the many uses for porcelain and ceramic tiles, which are known for their strength and resistance to moisture, are:

  • A kitchen’s walls and counters are both critical.
  • The floor of the kitchen
  • A bathroom’s partitions and shower stalls
  • Flooring in the bathroom

Many homeowners may have to drill through their floors and walls at some point due to its widespread use as a building material.

  • Projects that frequently necessitate drilling into porcelain tile include:
  • Setting up a towel railing
  • Enlarging and improving the shower area
  • Installing an additional appliance in the kitchen.
  • Decorations for the walls
  • Mirrors can be attached to walls.
  • The art of tiling to a specific floor measurement
  • Putting in the piping.

The Best Equipment for the Job

Planning is key to drilling projects’ success. You’ll be more successful with the correct tools and a steady hand.

The tile might be shattered if you don’t plan and prepare. You’ll need the following tools to drill through porcelain tile:

Drilling into porcelain necessitates a more challenging drill bit than the prepared material. The difficulty level here is really high.. The following drill bits are highly recommended:

Drill bits with diamond tips are incredibly hard.

Carbon and metal combine to form carbide, incredibly long-lasting material for drill bits.

A drill has a variable speed control.

Allows for low-speed drilling with a variable speed setting when necessary.

Lubricant that keeps things cool

No matter what drill bit is used, it will get incredibly hot. Cutting oil or even water can be used as a cooling lubricant for the bit.

Applying water with a sponge or spray bottle can be done, but you’ll have to do it a lot..

A novice do-it-yourself can make holes in hard porcelain tiles with the right drill.

A diamond or carbide drill bit may be necessary to succeed, so be sure to stock up on them. A standard masonry or tile drill bit will fall short in this case.

Purchase of a diamond bit may appear unusual to many first-time drillers. Despite this, carbide and diamond materials are widely used in many tools because they are long-lasting.

Know Your Tiles

Drilling through tile is a skill that requires careful attention to the material being worked with. You’ll have a better idea of the project’s scope if you know the specifics of the material you’re working with.

Because of their high density, porcelain tiles are more difficult to penetrate than ceramic ones. As a result, cutting through porcelain tiles is more complex and time-consuming than other tiles. A drill bit is also required to cut through porcelain tile’s hard surface. Drilling into stone tiles has the same consequences as digging into different materials.

With this background knowledge, let us have a look at the drill bits you’ll need to get started..

The correct drill bit is essential

Never use a worn-out drill bit on tile, no matter the material. Drill bits that have been used for a long time are less effective than new ones and increase the risk of destroying tile surfaces.

Use a particular drill bit for this work since conventional drill bits will not be able to pierce the tile’s hard surface. As an alternative, you should use diamond-tipped or carbide-tipped masonry drill bits. The first alternative is more expensive but long-lasting and can pierce even the most robust tile surface, such as porcelain. It is also more challenging to break through. In addition, they won’t burn out as quickly as masonry bits will.

In contrast, carbide-tipped masonry drill bits are the most commonly used for drilling into the tile. Even so, this sort of drill bit can be used for glazed tile and porcelain, although it is not advised for porcelain clay pots. Diamond drill bits as our EASY GRES are required for drilling porcelain stoneware and other hard materials.

This work can be made more accessible by RUBI’s extensive selection of drill bits, which are ideal for drilling into the tile. You may want to have a peek at them if you’re so inclined.

Measure & Marked out 

With tiles, it’s tough to hold down the drill bits since they move around on the surface, preventing you from drilling a hole. That, my friends, is a significant issue. If you make a mistake, you risk scratching or even cracking the tile.

Masking tape can stress the region where you intend to drill a hole. Then, using a ruler and an X-acto knife, mark the perimeter of the work area and apply the masking tape. After you’ve applied the masking tape, take another measurement to be sure you didn’t lose the hole. Then, when you begin drilling, you will have sufficient surface traction to hold the drill firmly.

With more than one hole to drill in your project, you can use wood as a template to save yourself from repeatedly going through this process. Drill a small hole into a piece of wood, making sure it’s the same diameter as the bit you intend to use. Hold it in place above the drill hole with your spare hand.

Once the drill bit is in place, go to 

The fun begins now. This section gives you a feel for drilling into the tile. The drilling can start as soon as the surface is designated or a wood template is in place.

We’re not sure if this is a problem since tiles are built to survive a lot of damage, which makes them immune to drilling. However, attempting to rush through the process can jeopardize your entire effort.

Drilling through tile is a time-consuming process that necessitates perseverance on your part. Slowly and methodically begin drilling. Be patient, since breaking through the thick glazing may take some time. Make sure you don’t fall prey to the idea that going full speed is more productive. It’s more likely that you’ll overheat the surface and cause vibrations that could cause damage.

Consistent pressure, but not too much pressure, should be used. If you don’t drill into the tiles, you’ll end up with cracks.

Ensure that the drill is always kept cool

Maintaining an excellent working environment is an integral part of drilling through tile. To keep the drill bit from overheating, use a little wet sponge.

If you’re working alone and are unable to hold the drill bit and the wood pattern in both hands at the same time, you can spray water on the drill bit periodically.. However, never use water in the motor section to avoid damaging the drill’s motor.

Another option to prevent the drill from overheating is to place a moist sponge underneath it. In addition to controlling the exercise from overheating, this method allows you to collect tile-related dust and debris. As a plus, you’ll prevent water from flowing down the wall onto the floor.

An important point to remember is that diamond bits don’t need to be constantly cooled, unlike carbide drill bits. If you let them cool down, they’ll keep working even if they’re overheated. So drilling slowly, not applying excessive pressure, and rinsing the drill with cool water will all help extend your instruments’ life.

After You Reach the Wall, Change the Bits 

You managed to sever the tile and hit the wall without causing any harm to it. You can now take a deep breath. All left is to drill a hole in the wall and then attach the accent pieces.

To avoid smashing into the wall, use a light touch when drilling.. An unstable anchor and loose accents will result if a wall is torn apart. It’s possible to switch drill bits if you think the one you’re currently using isn’t working as well as you’d like. To use a tile drill bit to bore a hole, however, you must drill slowly and steadily.

Did You Learn How To Drink Tile

Enjoy the finished product for a bit. You deserve a pat on the back, so go ahead and do it. Congratulations on a job well done. That’s a no-brainier! You did a fantastic job, my friend! The next project you take on will be more accessible now that you have more experience. The RUBI wet drill bits can be used in a variety of ways:

Several considerations must be made before beginning to drill through tile. To begin, you’ll need the appropriate equipment. If you don’t have the right drill bit, your chances of making a mistake increase dramatically. You need to wait for things to work out the second time. A race to drill holes in the tiling isn’t taking place.. Digging through the tile must be done carefully and steadily. Maintaining a relaxed environment is also essential. Cracks in the tile might be caused by overheating.

Finally, you must not give up on your goals.. With repetition, drilling through tile will no longer be a process that causes your heart to plummet to your stomach.

Porcelain Tile Drilling Mistakes You Don’t Want to Make

According to an expert handyman, people make a few frequent blunders when trying to drill through tough tiles.

If you learn from the pros, fewer blunders and more expensive repairs might be avoided. The following are a few of their recommendations for drilling through porcelain:

Drilling slowly and steadily is the key to success in this competition. Avoid using a hammer drill, which works in the same manner as a hammer and nail. A break in the tile will almost definitely result from such pressure.

As soon as you see smoke coming from the drill bit, you should put the drill down and check to see if it has been damaged. A standard drill bit will not do the job since it is not long-lasting enough.

Do not begin work until you have thoroughly planned it; it will be worth your while to put in the time upfront. It’s also important to exercise caution when working near a tile’s edge, which is particularly prone to cracking.


How do you drill porcelain tiles without breaking them?

Diamond Tipped drill bits are required for drilling porcelain tile, whether it’s on the wall or the floor, because they’re designed for more complex, denser materials like natural stone. While some drill bits are packed with wax to prevent the bit from overheating and harming the diamonds, others use water cooling to keep the gems safe.

Are porcelain tiles hard to drill?

Porcelain and natural stone tiles are more durable than ceramic tiles, so you’ll have to work harder to get to the other side. In addition, you’ll need a particular drill bit designed to pierce the hard glaze and the body substance of porcelain.


This guidance will put you on the right path to successfully drilling into the tile. Make sure you’ve got the appropriate drill bits, keep them cool, and calm and steady are some of the most critical things to remember! When drilling through tiles, patience is the essential trait you can have. A cracked tile is almost always the result of hasty work (and failure to control overheating during the drilling process.
