How To Drill Through A Porcelain Tile Without Cracking It

Porcelain tiles are a popular choice because of their durability and scratch resistance. These qualities can make drilling porcelain difficult.

Drilling through porcelain tile is one of the most difficult do-it-yourself tasks.

The difference between success and failure can be made by knowing the right tools.

Today we will show you how to drill through porcelain tiles without cracking them.

The Right Tools

Planning ahead is key to drilling jobs. It is essential to have the right equipment and steady hands.

The type of drill bit used to drill through porcelain tiles makes a big difference.

A diamond-tipped drill tip is recommended for porcelain tile. This drill bit is very hard and can penetrate porcelain tile.

Failure to plan and prepare can lead to smashed tiles and big mess. You must have the following:

Use the right drill bit

Use the correct type of drill bit when drilling porcelain tile. You will get a better view of the hole if you use the right bit.

The drill bit should be as hard as the surface to which it is being used – which can be tricky with porcelain. This is a very difficult material.

Even a beginner can use the right drill bit to make holes in porcelain tiles.

Drill bits with diamond tips

The diamond powder in tiny pieces embedded in diamond drill bits gives them extra cutting power.

These bits are useful for bathroom applications, where you need to drill through tiles in order to mount towel racks or vanities.

Many first-time drillers may find it strange to consider purchasing diamond drill bits.

Carbide and diamond are extremely popular because of their durability.

Carbide-tipped drill bits

Carbide is a combination of carbon and metal that makes it very durable.

Carbide drill bits are usually made from steel and have a carbide tip. Because of their strength, they are often used in industrial applications.

They are capable of cutting through concrete, masonry and tile.

Drill with Variable Speed Trigger

Variable speed drills allow you to drill at a low speed when necessary.

Drills of today often have a variable speed trigger. This means that the drill spins faster if you squeeze harder.

You can control your drill’s speed between zero rpm to the maximum speed with a variable speed trigger or multiple speed settings.

Cooling Lubricant

It doesn’t matter what drill bit you use, it will heat up quickly. The bit can be cooled by using a cooling lubricant like water or cutting oil.

You can use a spray bottle or sponge to water, and you should be able to apply it often.

Preparation is key to success. This may include purchasing a diamond or carbide drill bit. This type of job is not possible with a regular tile or masonry drill bit.

Steps to Drill Through Porcelain Tile

After you have the tools, it is time to learn how to do the job properly.

This experience can be made easier by many skilled craftsmen. These steps will help you drill porcelain tile.

Step 1: Make your mark

Use masking tape to mark the area you want to drill.

Tape will prevent the drill bit from sliding and marks will help you be precise with your drill.

After marking the hole, you can use the drill bit. You will need an angle to drill through porcelain tile. This will allow the drill bit to cut the tile at an angle.

The drill bit should be held at a 45 degree angle. To cut through tile, tilt the drill.

Sometimes, the drill bit can slip and cause cracking of the tile.

Step 2: Slowly start

Start at the lowest setting of the variable speed dial on your drill. Do not apply too much pressure as this could cause cracking.

It is important to maintain a steady pace, and only apply pressure to one tile.

It is important to maintain a steady, slow pressure and a low drilling speed.

Step 3: Let the drill bit cool off

You should ensure that the bit is not too hot when using a drill bit with a diamond tip.

Drilling too fast can cause the hole to break and crack the tiles.

Dip your drill bit in cutting oils or spray it with coldwater every 15-30 seconds. This will prevent overheating and any damage to your drill bits

Wipe the drill bit with a damp rag

Step 4: Continue

Continue these steps until the porcelain tile is drilled.

Important Things to Remember

It is important to drill porcelain tile slowly and with a steady hand.

A bit with a sharp tip is best for drilling porcelain tile. While a blunt bit can drill holes in tile, it won’t make a hole.

You should drill the tile using a diamond bit at a steady speed.

Too fast drilling may cause damage to the surface and ruin of your project.

A more successful job will be achieved by applying even pressure and stopping often to cool off the drill bit.

Drill bits can become very hot, especially if they are used to drill through porcelain tile.

You should be cautious about the heat generated by friction.

What to Avoid

A handyman who is experienced will tell you there are some common mistakes when drilling through very hard tiles.

Learn from experts to avoid costly mistakes and save money. Here are some of their top tips for drilling through porcelain.

Don’t drill too fast

Slow and steady wins this race.

Use a hammer drill only

The hammer drill is fast and moves back and forth much like a nail and hammer. This force will cause cracks in the tile.

If your drill bit is red or smoking, you should stop.

The drilling action is heating up and friction is creating smoke.

Don’t try to use a regular drillbit

Regular bits won’t be strong enough to do the job.

Don’t start the job without properly planning

It is important to take the time to prepare.

Be careful when working close to the edge of a tile

Porcelain tiles are especially susceptible to cracking so be cautious when working around the edges.

What makes Porcelain Tiles Special?

Different tiles have different properties. The hardness of a tile, just like rock, can vary greatly. It could be a crumbly adobe or durable marble tile.

Porcelain tiles have a unique quality because they are very hard. They are nearly as hard as granite rocks.

There are many materials that can be used to make tiles. Porcelain tiles are high in silica. The tiles are baked in a high-heat kiln, creating a hardened tile.

Porcelain is basically a man-made ceramic material. It is extremely difficult to drill through because it is dense and heavy.

Glazing porcelain tiles creates a shiny finish. This makes drilling through tiles even more difficult because of its slippery surface.

Porcelain and ceramic tiles are very popular because of their water resistance and durability.

This includes kitchen backsplashes and kitchen floors, bathroom walls and shower enclosures, and bathroom floors.

They are very popular as a wall and floor material so homeowners might need to drill through them.

Drilling through porcelain is required for certain projects

  • Towel rack installation
  • Remodeling your shower enclosure
  • Installing a new kitchen appliance
  • Hanging decor
  • Attaching mirrors
  • To fit a floor, cut tiles
  • Installation of pipes

These are just some of the potential issues that could affect homeowners and workers in construction. Porcelain tiles are very popular because they are strong and durable.

These same characteristics make it difficult to work with.

Even a novice handyman can succeed if he is well-prepared with the right tools.

Most Frequently Asked Questions

What is the average time it takes to drill through porcelain tile?

It is possible to spend as much as three to five minutes per hole. The right drill bit can make the process faster and more efficient.

Do not rush, you will make it through!

Do You Need to Wet a Tile Before Drilling?

Yes, it is important to use water to drill through tile, but porcelain tile is especially important.

When the tile and drill bit come in contact, a lot of friction is created, which generates a lot of heat.


To drill through porcelain tile, the first step is to position your drill bit at 45 degrees. To cut through tile, tilt the drill.

Sometimes the drill bit can slip, which will increase the chance of cracking the tile. It is important to apply pressure only to one tile at a time and keep the drill bit moving in a steady manner.

You should ensure that the bit is not too hot when using a drill bit with a diamond tip.

Although porcelain tiles are inexpensive and can be stylish, it is important to drill them correctly.
