How to cut a hole for the sink in porcelain stoneware

Independent drilling of a hole in a granite sink

Gone are the days when most people had enamel sinks in their kitchens. Today, everyone can, depending on the kitchen interior designer, install sinks made of a variety of materials. However, such “permissiveness” can cause difficulties if you, in addition to the standard mixer, wish to install additional equipment (filters or systems for water purification, detergent dispensers, etc.).

This is especially true for mine, which are made of natural or artificial materials (granite, porcelain, ceramic, stone, etc.). The high hardness and brittleness of these materials represents a certain difficulty in drilling, especially if you have decided to make the necessary hole yourself.

In order to drill a hole in a granite sink you will need: a manual drill, a carbide or diamond drill bit, a pobedite drill bit with a diameter of 6. 8 mm, a lubricant-coolant and a “sprayer” which can be made from a bottle of household detergent. As a cutter, at home you can use a diamond or bimetallic “crown”, which can be purchased at construction or tool stores, and as a cooling lubricant, it is desirable to use unisor or emulsol. If you cannot afford these liquids, you can use soapy water. And actually the kitchen sink itself, I got myself a model GRANFEST F-12, black.

On most models of brand sinks, on the back side there are some small indentations, which will help us to avoid alignment of the future hole. According to the manual of the equipment you are going to install additionally choose a place for its future installation.

Take a drill bit with a diameter equal to the diameter of the drill bit or drill head and drill the hole. Important: The drill bit must “float” in the coolant. There are several reasons for this: 1. You do not need to apply unnecessary force when drilling. 2. You can save on the sharpening of the drill bit by doing this, which prolongs its service life. 3. And finally, it will help to avoid excessive heating of the granite sink itself and thus prevent its destruction.

After you have drilled the hole turn your sink over and mount the drill bit or core bit in the drill and start drilling to the desired diameter. Needless to say, that the diameter of the cutter or core bit should be equal to the mounting diameter of the additional equipment. All modern faucets, soap dispensers have a 3,5 cm hole. Drill the hole with the cutter or head from the front side, as the output can be chipped because it is almost impossible to determine the last seconds of drilling and reduce the load on the drill in time. Do not forget that even at this stage of drilling you need to “fill up” the tool with your coolant. Unlike drilling a hole with a drill, you should not put too much pressure on the drill.

As a result of the last stage of the work, you should have a kind of bagel, which will indicate that you have not distorted the drill during drilling and performed your task qualitatively.

Additional tools

For porcelain tile drilling professionals additional equipment can be used: ballerinas, a centering device for diamond drill bits, a centering device for diamond drill bit, conductor, a bottle for the liquid temperature reduction of diamond drill bits or drill bits. A screwdriver or drill, possibly a drill bit holder, is a must for the job.

Ballerinas are used when there is a need to drill a very large hole in porcelain tile. They are fastened in the drill in the same way as the drill.

A centering device is used to prevent the drill bit from shifting. For disposable work, it is acceptable to quickly make a device out of plywood or wooden pieces (by drilling a hole in them of the required size).

Conductor is a professional device for maximum precision in porcelain tiles. Its purpose is to guide the drill precisely to a given point. the drill bit or core drill bit is designed to be cooled with a constant stream of water.

Drill porcelain tiles before or after installation?

As you understand, it is possible to drill as already glued to the floor or walls tiles, as well as those that are just going to put. It is, as they say, a matter of taste. I made the holes on the finished surfaces. In each case, there are pros and cons.

it is convenient to choose the place of drilling, it is possible to put a shelf or a holder, to move it;

the hole is made in one time to the right depth, you do not have to additionally drill the wall;

There is no risk of dismantling the damaged area, but you only have to drill from the front side;

It is more convenient to drill horizontally lying, and not glued vertically tiles, so it is easier to avoid tilting the drill at an acute angle to the tile;

Additional selection criteria

With what to drill a hole in porcelain tile relative to the cutting element is clear. However, this is not the only thing to consider when choosing a tool. It is also necessary to consider the required parameters of the result and the number of drilled holes.


Before drilling a porcelain tile, a precise marking is carried out. Because here, errors are sometimes unacceptable. Here the diameter of the hole is important for the choice of drill bit. Manufacturers offer almost any size tooling, but in great demand are 6-12 mm with a step of 2 mm.

The range of permissible dimensions of diamond drill bits is noticeably wider than that of drills. It is 8-150 mm. often masters use tooling from 20 to 100 mm. This is explained by the parameters of pipes and boxes for engineering communications.

It is worth noting one point regarding the marking of products for drilling. Diameter of tooling can be specified both in mm and in inches. In the case of the need to form precise holes, it is necessary to take into account such a fact.

When deciding what to drill porcelain tiles, you can be guided by the recommendations of craftsmen. They are for small or large holes.

Small diameter Large diameter
Small dimensions include dowel or dowel pins for self-tapping screws/nails. Here, the best solution would be a diamond drill under the peorator and a ring tackle. Only diamond drill bits can be used to form holes for utilities.

It is worth mentioning that tubular-type tools are subject to coolant (water). This rule eliminates tool overheating from additional friction against debris. A drills refer to porcelain drills for dry drilling. In the case of drill bits, the novice craftsman is recommended to use a centering rod. It is designed to correct the position of the cylinder, eliminating undesirable slipping on the surface of the decorative surface.

Working life

Another important criterion for determining what is better to drill porcelain tiles. operating life. To form several holes, it is sufficient to use a pobedite drill or drill bit, a diamond-coated drill bit. They are relatively easy to work with, the cost is quite low.

For large-scale work or professional activities the choice should be made in favor of tubular counterparts. Here, the drilling takes much more time, plus the periodic cleaning of debris and the cooling of equipment. But the productivity will be considerable without damage or destruction of cutting edge.

What can be drilled with for porcelain tiles?

At the moment, the most effective in porcelain tile drilling are diamond drill bits and diamond drills. Crowns are cheap enough and it is their main advantage over other cutting material. When creating holes using diamond drill bits, the face pressure on the plate is reduced and the speed of work is increased.

The disadvantage of crowns is their short service life.

To bring it together. An 8 mm tile can be drilled a maximum of five times with one drill bit.

Ring sintered diamond drill bits have a significantly longer service life. The drill bit’s working surface is at least two millimeters thick. The disadvantage of working with such drills is the low rate of obtaining holes. It takes up to 5 minutes to make one hole, but up to 100 of them can be made with one drill bit. For your information. Often, in order not to waste much drill bit, drill the hole not all the way through and leave a third of the tile untouched. This part is then simply knocked out. Therefore, in order not to see the chips that appear when knocking out the remainder, you must start from the front side.

It is a good idea to use a special pulley or pole for this work. This makes it easier to work, the hole is smoother, and the tool life is longer. Large revolutions in this process for the drill is not necessary, so you can take the most simple drill. The drill should be perpendicular to the board, otherwise the material can be destroyed.

Important. Peorator or impact drill must not be used categorically.

Drill cooling is obligatory. At home, this can be done with a jet of water from, for example, a plastic bottle. A sponge dampened with water will also work. If the drilling is done correctly, the drilled cylinder at the end of the process will simply fall out of the plate. Often, chips and cracks appear on the underside of the board in the place of drilling, but it will not affect the appearance. Chips can easily be removed with glue and will not affect the further process of installation.

Drilling instructions

Before you drill porcelain tile, decide on the task. If you need a neat hole with smooth edges, for example, to mount a socket, you need a straight cut and exact observance of the diameter. This is a job for diamond crowns or ballerina.

If the place of drilling in the future planned to be masked by a decorative element, such as a painting, jewelry accuracy in drilling makes no sense to observe. A drill bit such as a beater would do the trick.

If you have no experience, then experts recommend using drill bits with a guide middle.

Try not to work with a drill bit on a concrete floor. Put plywood under the tiles. It will take some of the vibration and pressure, protect the tool from “sticking” into the concrete, and help achieve an even cut edge.

Diamond drill bit

Drilling porcelain tiles at home with Pobedite is an activity that requires skill and care. To make the hole, make sure that there are no voids under the tile, otherwise the tile will burst. Knock all places for future drilling with wood. As soon as you hear a ringing sound, there is an air lock.

It is not recommended to work with pobeditom in the area of the joint in order not to spoil the appearance of porcelain tiles. If absolutely necessary, put duct tape right in the middle of the inter-tile joint and work at speeds up to 500 rpm.

The quality of almost any tool depends on the manufacturer and brand.

When working with pobedite drill bit fix the working surface beforehand. You rarely get high quality and accurate work by weight, especially if you are a beginner in this business.


Working with diamond drill bits requires an axial or centering drill. If you do not have one, use a template template additionally. To do this, a plywood sheet is attached to the place of drilling and secured with tape, so that it does not shift. As soon as the drill has overcome the template and has sunk 1-2 mm into the porcelain tile, the template is removed and the work continues without it.

Drilling can take place with or without coolant. The only thing that is important here is to mark the tiles accurately.

It is recommended to combine drilling with rocking. That is to say, little by little, by a couple of millimeters, to change the angle of inclination in relation to the working surface. It promotes cooling at the point of contact of the tile with the drill bit and helps avoid overheating.

It happens, the crown gets stuck in a partially made hole, its segment breaks, or the sludge gets clogged in the depth. The bit or its parts can be extracted with a reverse hammer.

The ballerina is handy when many holes of different diameters are to be made. Drill a hole with pobedite or a steel pen before working with a circular nozzle. This way the ballerina will not shift and spoil the face of the decorative tile.

It helps to lubricate the glossy work surface with machine oil. The process will go smoothly and evenly, there will be no sudden jumps and unplanned displacements of the tool.

Ballerinas are used in those cases where there is a need to drill a very large hole in porcelain tile.

How to drill

There are several ways to drill a hole in porcelain tile. Each has its own advantages and special features.

Wet surface

Wet drilling is the regular wetting of the nozzle and tile surface with water or oil for cooling. Wet” work with the diamond drill bit by rocking the tool smoothly from side to side. This is to evenly remove the wet cuttings from the drilling area. It is recommended to carry out such manipulations every 5-7 seconds.

Diamond drill bits tend to heat up during operation, so they need to be cooled down to prolong their working life.

For personal protection be sure to wear special glasses. Wet debris can fly to and fro. And covering your eye or regularly dodging will prevent you from making a perfectly straight hole.

Do not pour too much water. A small, thin trickle or sometimes just a couple of drops is enough. Add moisture with this type of drilling as soon as you see the first puff of dry dust rising.

Dry surface

Use a home vacuum cleaner for this type of drilling. It helps to remove the dust and sludge generated during work. Performing the dry process is best done with diamond bits that already have cooling oil in the cavities. This helps prevent “soaping” of the edge and makes the result tidier.

It is important that there is enough space between the segments of the nozzle for the sludge to escape. Otherwise the tool will be blocked.

Dry drilling of porcelain tiles is used in those cases where you need to get a large number of holes in a relatively short time.

If you do not have a vacuum cleaner, try to interrupt the work and remove the fine dust. You will spend more time, but the result will exceed expectations.

Dry drilling method is used when you need to make a large number of holes in a short time.

On the floor

If the tiles have already been laid and glued on the floor and you need to drill a hole to install, for example, partitions, it should not be difficult to work. In this case, the tile surface doesn’t move or vibrate, especially if it’s planted on the glue.

The main condition for quality work is to ensure that the exact placement of the drill bit in the chosen place, so that it does not shift. For this purpose, stick a tape, and the tool will not slip on the glossy surface. Make sure that there are no voids under the tiles, otherwise cracks will appear. And it is important to bring the drill to the floor already plugged in, rather than holding it stationary.

Drilling should be carried out strictly perpendicular to the surface to be treated.

It’s easy to drill on the floor using the wet method.

On the wall

If you drill into the tile from the matte side before gluing it to the wall, it will destroy the surface. When working with porcelain tiles it is important to keep the angle of the tool. Then the wall will be your helper. Work at a slow to medium speed, avoid hard knocks and jolts, and apply the same amount of force while working.

As in the work with tiles on the floor, mark the center of the future working circle and stick a piece of masking tape. This will prevent the tool from slipping.

Vary the diameter of the drill bit. If possible, make an initial cavity with a small-diameter bit first. Then finish it off with a coarser one. These simple manipulations will help you quickly make a hole of the desired diameter.

Specialists recommend using special framework-fixators that can hold the drill or other tool in the right position.

Drilling a hole in a ceramic sink for a faucet

The trauma room is full of people who thought they didn’t need insurance. And the stores are full of sinks that do not have holes to install the faucet. And no sink that has two holes, to accommodate two faucets, one for each hole. It’s understandable. Why put two faucets in one sink?

And if you imagine from time to time that you are the only hole in the sink and you get lonely in an island bounded by its outer, smooth ceramic edges, who will understand that, and who can you tell about it, expecting at least to be listened to, not to mention sympathized and understood?

hole, sink, porcelain

It seems to me that two holes in the sink for a faucet would be too much, and none would be too little. So today we will talk about how to drill only one hole in the sink. In a ceramic sink that does not have any holes to install a faucet from the day of his birth, if only sinks have such days, birthdays.

Some people do not understand the importance of having a hole in the sink for the faucet and consider any text containing a large number of words “hole” to be nonsense. So, I’ll try to write more simply, without abusing words like “hole” and “sink”.

What should be the diameter of the hole for the faucet

If we focus on the existing standard, it should be noted that the siphons, which are installed under the sink, in diameter are rarely more than thirty-five millimeters. If the sink already has a hole for the faucet, then most likely all questions will fall away by themselves, as it should fit.

But some companies have models of sinks, usually made of ceramic, that do not have holes for the faucet at all. The thing is that there are faucets, which are mounted either on the rim or on the wall over the sink. This raises the question of how to drill a hole easier. However, if you have a drill, the right drills and minimal skills it will not be an insoluble problem.

If you use a drill bit that has a diamond core, for example, with the same thirty-five millimeter diameter, you can easily make the required hole. It will not be necessary to somehow cool the drill bit, pour water. With modern equipment, none of this is necessary. With such a drill bit you will be able to make a perfectly flat hole, without any chips.

After the hole will be ready, you need to think about sealing. It will be necessary to put a gasket on the sink, and when the faucet will be installed in its place, it is not unreasonable to treat the joints with silicone sealant. This will prevent any possible leakage.

How to work with a tubular drill, in the following

Please note that the authors of the video clips show their understanding of the technology of working with tiles, which is not the final truth. Often there are alternative ways of drilling, using additional processing of the edges of holes and other actions. However, all methods require accuracy and attention, so as not to spoil the tool or the surface of the coating.

Useful Tips

When drilling tiles, there are often one-type situations that require the use of standard work techniques. Consider a few useful tips that can save the master from surprises or defects in the work:

  • Before you drill a tile, it is recommended to wet it, immersing it for a while in a container of water. This will reduce the heat of the tool, reducing the heat load on the material.
  • In order to speed up and facilitate the process of cleaning after drilling tiles on the wall, it is recommended to make a bag of newspaper and tape it to the wall under the future hole. During the work, the dust will fall into the bag, which at the end of the work is removed and thrown away.
  • Do not rotate the drill at high speed. The only case where it is possible to work at a high enough speed is when working with soft wall tiles.
  • Some sources recommend first tapping the hole to keep the drill from slipping out of alignment. However, this step is only necessary for “ballerinas” or carbide tools with a gentle angle of inclination of the cutting edges. For lance bits, coring is not necessary.
  • If the hole is close to the edge, proceed with care. The drill often slips into the tile joint, so it’s better to make a small size hole first, and then enlarge it with a tool of the right diameter.
  • If you make a hole for a dowel, it is recommended first to drill the tile with a javelin drill bit that is 1 mm larger in diameter than the size of the drill bit. This prevents damage to the tile and chips caused by drill bit runout.

These simple but very useful tips can help you avoid tile and tool breakage when drilling holes of different diameters.

Smaller diameters are best shaped with pobedite drills. Such approach is actual for diameter up to 12 mm with tiles. Drill or drill bit is selected/adjusted to a power of 800 watts. The chuck must be centered to avoid collision with the tile. If the surface is smooth, then on it to avoid slippage of the drill stick 4-5 plates of painter’s (paper) tape.

Standard holes up to 50 mm in diameter can be drilled with pobedite drill bits. It is better if they are equipped with an alignment drill. It will not allow the cylinder to move out of alignment. The cut begins with a small speed until the formation of the starting furrow of 3 mm in depth. further the speed can be increased.

Non-standard sized holes (55, 68, 71 mm) can be made using ballerina. It is a device with a centering drill on which the cutter is clamped by means of a rod. The distance between the elements is adjustable, the fixture is a clamping screw. The latter is considered the weakest point of the tooling, but insufficient tightening of the design leads to violations of the correct drilling process.

Often we have to decorate the inlets for sewer or ventilation outlets with a diameter of over 100 mm. Here, an angle grinder with a diamond disc is used. Sideways cutting is done less frequently without a blade guard. often make individual notches, nabrechtayut tiles with wire cutters or pliers, trim the edges file or disk. The third variant. an electric jigsaw.

The main points in a nutshell

Tile cutting tools with carbide cutters, rollers, or interchangeable discs are used to cut tiles at home.

Ceramic tiles are practically not cut with the glass cutter. Use a handheld tile cutter.

With replaceable diamond discs it is acceptable to use an angle grinder, circular saw, electric tile cutter.

Artistic cutting can be performed with a hand jigsaw with a diamond wire or a more advanced waterjet.

Circle-shaped holes can be made with a drill bit, crown or ballerina. For a large diameter resort to an angle grinder or electric jigsaw.
