How to cut a hole in the tile for the faucet?
The diameter of the hole under the mixer can be different, 32. 35 mm; so that the drill does not slide on the surface, glue a strip of tape on the place of drilling; so that the hole in the tile under the mixer was accurate and even, without jagged edges, use a sandpaper coiled on a round stick.
- First, we draw a marker on the back side of the tile;
- On an angle grinder, install a dry-cutting disc;
- Be sure to guide the tool away from you. Try not to interrupt the line for the trimmer.
How to cut a hole in the tile for a pipe?
When cutting holes for a pipe experienced tiler enough one angle grinder with a diamond disc for concrete. For drilling deep through holes in walls it’s better to use special drill bits or pobedite concrete drill bits.
- Tubular diamond drill bits.
- Lance drills with a carbide tip.
- Carbide tipped twist drills.
The process of cutting a large hole in the tile with an angle grinder
It is necessary to draw the contours of the hole on the tile. If it is matte, then an ordinary pencil perfectly writes on it, on a glossy one, it is possible to draw with a marker or a cosmetic pencil for eyelashes.
Then start the angle grinder with a diamond disc, and at an angle begin to undercut the contour. At first the task is only to cut through the glaze without forming falcons.
After that, the angle is increased. You need to make a deeper groove from the marked outline.
So for a few revolutions of the angle grinder is required to deepen through the tiles.
The result will be a hole, but with quite jagged edges. It needs to be sanded. This is done with the tip of the disk, but already directed from inside the hole at a slight angle. Often, grinding is not even required, as the uneven circumference is closed.

Holes in the tiles for faucets, outlets and pipes
To drill holes in a wall tiled with ceramic tiles for outlets, diamond-coated core drills are used. Crowns can also be for drilling metal and wood, so it is important to use a crown specifically for tile. Core bits are available with or without pilot drill bit, which makes drilling easier. In the first case, the center of the circle to be cut out is tapped, a drill bit is positioned on the spot and drilling is performed.
The “ballerina” makes it easy to adjust the size of the hole
As the center drill goes deeper, drilling is performed with the crown. If the drill bit is not centered, the contour of the circle is drawn on the ceramic tile, the drill with the drill bit is placed on the contour, low rpm is turned on and, pressing alternately on the opposite edges of the drill bit, the groove is made along the contour and then drilling. It is possible to make a conductor out of plywood, which is a cut-out template of a circle of the same diameter as the drill bit. The stencil is placed against the wall, the crown is placed in the circle, and drilling is performed, in which the stencil will not allow the crown to move.
When drilling, the crown must be periodically cooled in water to prevent overheating and deterioration. Tile drill bits are also suitable for porcelain stoneware.
Around the mounting box under the outlet in such a hole should be a place for cement-sand mortar. This is necessary for a firm fixation of the box and socket.
Drilling a tile during installation on the wall
If you need to make holes in the tiles for mounting boxes, pipes or a faucet in the process of laying ceramics on the wall, you can also drill them in different ways.
On the face of ceramic tiles alcoholic marker draw a circle of desired diameter and along its contour, also without leaving the boundaries, drilled holes with a diameter of 3-4 mm at small increments with a concrete drill. Then, a grinder (angle grinder) with a disc diameter of 115 mm, designed for cutting stone, make 2-3 through cuts inside the contour, and use pliers to blot out unnecessary fragments from the tile. The edges are processed by rough abrasive paper, put on a round bar of suitable diameter, to flatness and absence of chips.
The following method is to cut a circle in the tile by cutting a groove with a grinder on the contour of the circle applied to the glaze, then make through cuts crosswise inside the contour and remove small fragments with wire cutters. The chips on the edges of the hole are removed with coarse sandpaper or a file.
Drilling a hole using a drill bit is done by rotating it
You can also make a round hole in the tile before laying with a special device called a “ballerina”. The attachment is a movable cutter mounted on a bar, which rotates by means of an electric tool around the axis of the center drill. The process of drilling with the “ballerina” consists of the following parts:
- Marking the center of the circle;
- setting the cutter to the desired diameter of the circle to be cut;
- glaze cut;
- drawing a groove on the back of the tile;
- Finishing of the circle from the front side.
Thanks to the ability to move the cutter along the bar, the tool can be configured to cut a hole of the desired diameter within the length of the bar. This eliminates the need to buy drill bits of different diameters.
To make a hole for a socket in the tile can also be a method of beating out. On the tile with a marker to draw the contour of the circle and in the middle of his drill 2-3 located close to each other holes, and then use pliers crumble the walls between them. Then, using the hammer placed on the floor as an anvil, light blows with the blunt end of the chisel crumble the edge of the hole in a circle, expanding it to the desired diameter.
Mounting boxes for outlets and switches can be square, and if you need to cut a square instead of a circle, using a different tool and techniques. To make a hole for a box of rosettes rectangular format, an outline is drawn on the glaze with a spirit marker.
Examples of failed tile drilling for electrical outlets
To exclude the formation of cracks during the subsequent cutting, it is necessary to drill through holes with a diameter of 8-10 mm in the corners of the square. Then, after fixing the tile on the board, use a concrete disc grinder to make all-round slots. The edges and corners of the square for the socket are processed with coarse sandpaper or a pencil file.
Figures of complex shape are cut with a string with a diamond sprayed, inserted in a hacksaw for metal.
On large format ceramic tiles, except for porcelain tiles, complex cuts are made with an electric jigsaw with a diamond-tipped saw. Cutting out in porcelain stoneware is executed by means of a grinder a disk with a diamond covering.
To avoid breaking the tile when drilling, the distance from the edge of the hole to the edge of the product should be at least 20 mm.
How to drill holes in tiles for dowels?
Depending on the required size, it is recommended that the holes are drilled with different tools. In some cases it is necessary to use a core cutter, in other cases a drill bit 8-16 mm is enough. But it is possible and a situation where it will be difficult to do without the angle grinder.
To drill through the tile for dowels, you need a drill bit for tiles 1-2 mm larger than the plastic insertion for the screw. First of all, it is necessary to carefully drill a layer of glaze without excessive pressure. And then slowly pass all the remaining ceramic to the wall.
Directly to the wall surface, especially if it is concrete, you should drill with another drill a little smaller. It is not necessary and simply senseless to waste specialized and expensive tools designed for tiles.
What drill bits to use for different surfaces
How to drill a hole for taps or outlets?
To drill holes larger than 20 mm for pipes or electrical outlets, a small drill bit is not enough. Here it is necessary to use crowns or a ballerina. The first option is more expensive, but also easier to work with. And the second option allows you to dispense with a single tool, with which it is possible to drill holes of different cross-section in the cross-section.
If you do not have a ballerina or crown of suitable diameter, you must drill several small holes around the perimeter of the large one. After drilling them out, you will need to carefully cut out the center outlined in this way with pliers and trim its edges with a rasp.
You can also resort to using an angle grinder. But it will be difficult to drill even round holes with it. This is more of a tool for cutting tiles to the desired dimensions or for cutting rectangular pieces out of tiles.
Features of tile drilling
Making holes in the tiles is not an easy job. This material in the production process undergoes a number of technological processes that make it strong, dense and brittle. Particularly tough surface. Brittleness and lack of the slightest plasticity in this case can be considered the greatest disadvantages. With careless drilling on the tiles are always formed chips and cracks, it may even split.
Therefore, never apply overload when drilling. Vibrating action is also inadmissible, as well as switching on the tool at high revolutions.
For your information. Special drill bits are used. made of high-strength materials that easily penetrate dense structures. Suitable drills with a special cut and configuration of the working part.
Suitable drill bits
- Flute drill bits for tile drilling. It is convenient to make small diameter holes with these special tools. For example, for fixing dowels. They have the usual cylindrical tail for clamping in the chuck of the drill. Drill bits are also available in the size of standard bits, with hexagonal.
Spearhead drill bits for tile drilling
- Tungsten carbide drills with a single-sided, sharp-edged edge. They go very well into the material and easily penetrate the outer layer, which is the densest one. If the drills were produced by a reliable manufacturer, they will last a long time.
Carbide drills with one-sided sharp-angled sharpening
Diamond or corundum bits
- porcelain tile.
- Core drills with tungsten carbide coatings. They can be used for drilling tiles, granite and marble.
Tungsten carbide-tungsten drill bits
- “Ballerina”. a special drill bit. It is designed for larger holes and larger diameters. They are inexpensive, but they can be used to drill holes with a diameter of 3 to 9 cm.
How to drill holes in tiles: helpful tips
Before you start drilling, consider the following recommendations.
First tip. It is difficult to make a precise marking. The point of the future drilling is marked directly on the tile surface with a marker (pencil). However, it will work better if a piece of masking tape is applied to the area to be treated. Then you can make a marking. Visibility is excellent, and drilling is much easier to start, because the sharply sharpened drill will not slide off the mark.
This approach is more correct than drilling into the center. If you use a drill bit (sharp nail, dowel), the tile surface can be damaged. chips and cracks will form.
Second tip. High speeds in the process of drilling tiles is inadmissible. The speed range is within 100-400 rpm. It is easy to determine the required frequency by experimentation.
Third tip. You can use a drill with an impact function. Then, starting the work, you should disable this option and check the result.
Tip Four. When you make a drill not yet laid tiles, prepare a comfortable place for work. The tiles are laid on the surface:
Check that there are no hard particles left on the workplace. They will not allow the tile to adhere tightly to the surface.
Fifth tip. The cutting part of the tool can get very hot during operation. At the same time heated and the place of drilling, which cracks the tile. So, it is not necessary to press hard with the drill bit. Spending a little more time, it is possible to get a good result. And the drill has to be cooled periodically. You can, for example, dip it in machine oil and wipe it off afterwards.
The hole can be drilled directly on the wall, that is, after the tile has been laid. Then drops of oil can get into the interstitial grout. As a result, it takes a lot of work to remove oil stains.
Drilling attachment using a drill jig with coolant
Sometimes you have to use a forced coolant supply. Professionals usually use a special device. a pressure vessel with a conductor. Its tasks include:
The sixth tip. The drill bit must be held perpendicular to the tile surface.
Seventh tip. In the process of drilling ceramic (when holes of considerable diameter are made, it is felt especially), flies away a lot of sharp splinters, most of which are very small and sharp. Protect your eyes and hands.
Small diameter holes: how to drill them correctly
Usually on the wall covered with ceramic, fix it:
Then you use hammered plastic dowels, up to 1.2 cm in diameter. It is worth considering the situation when you have to drill a wall that has already been tiled, and the glue under it has had time to fully cure.
Step One. Determine the drill place. It must be at a distance of up to 1.5 cm from the edge of the tile. Otherwise the drill bit can slip into the joint between the tiles. Also the edge can break off during drilling or from overheating.
Step Two. After making a marking, insert the drill chuck of the appropriate diameter to install the dowel. This means that the hole must be wider than the diameter of the dowel plug, by 1-2 mm.
Step three. Insert the drill bit into the marked center. Drilling should be carried out at a slow speed. The most difficult is to overcome the top layer of cable. Drilling deeper will be easier.
Step Four. Once the drill has passed the thickness of the tile and reached the wall, it is removed. There is no need to spoil the tool, it is not cheap.
Next, you can work with a drill bit for peorizing the walls. Its diameter should match the size of the dowel. To continue drilling to the desired depth, you need to drill through the hole in the tile freely.
The work must be performed extremely carefully, otherwise an accidental warping can damage the edges of the hole in the tile, because when working with a long drill is always marked at least a slight runout.
Step Five. It remains only to put a dowel in the hole, gently score. But a clumsy movement can easily ruin all the work. Any accidental impact on the tile gives a crack.
Step Six. You can screw in a screw, a hook, other fastener.
How to drill a hole in the tile with an ordinary drill bit
Let’s imagine that you are faced with the task of hanging a holder for toilet paper. The toilet is tiled, which makes the task much more difficult. What must you do to drill the hole cleanly without cracking the tiles?? I will show you the way how to do it easily, and even with an ordinary concrete drill.Of course, the toilet paper holder is just an example. With this method you can hang anything: a shelf, a mirror, a towel rack, etc.п.
How to drill a hole in a ceramic tile with a regular drill bit
No doubt, if you have in stock a special drill bit for glass and tile, then of course it is better to drill with it. I don’t have a tool like that, because I don’t do a lot of repair work. Story from the category of home economics.So all I’ve got is A set of concrete drill bits.So, here we go. Let’s try on the place where there will be a holder for further installation. At the point of drilling glue pieces of duct tape or masking tape.
Duct tape is not only for drawing the markings. It prevents the divergence of microcracks during drilling and protects the tile from breaking.
Now the most important operation. Take the concrete drill bit and put it on the mark. Start hitting the drill with a light hammer, periodically turning the drill with your hand. The time for one hole is about one minute. The result should be a small groove in the tile.
Drilling: general guidelines
For drilling work, you should not use too high revolutions: it is enough if the tool creates rotation at a speed of 100 to 400 revolutions. The exact desired number of rotations depends on the type of material and its coating.
It is not necessary to create too much pressure on the working tool. this can lead to the destruction of tiles and overheating.
If no water blowers are available and the tile is level, local cooling can be used. For this purpose a plasticine funnel is modeled around the area of work, which is filled with cold water.
In order to drill properly, the drill or screwdriver should always be placed perpendicular to the work area. Without special tools, you have to monitor this parameter yourself.
You should never disregard protective equipment. drilling work on ceramic tiles is always accompanied by a flying out of small splinters, which are especially dangerous in the eyes.

What you need for drilling ceramic tiles
What, in fact, is the essence of the whole problem of drilling ceramic? Features of the technological process of tile production. high temperature firing, the high density of the material and its surface strength (especially if there is a layer of glazing) have in addition to the obvious advantages logically ensuing disadvantage. Ceramic products are characterized by fragility, lack of any kind of plasticity, and the tile with careless handling, cutting or drilling can easily give a crack, chips, and even break into several fragments.
Unfortunate result of unsuccessful drilling
In addition, the material itself has a very strong abrasive effect on the cutting tools during processing, and conventional drills will dull in a matter of seconds.
Conclusions. for drilling you should not apply excessive load, vibration action, high number of revolutions of the tool. And, accordingly, the drills themselves must be made of high-strength materials, capable of passing the dense structure, and have the appropriate configuration or sharpening.
So, what you may need for drilling tiles:
|Electric drill. The main condition for it is the obligatory presence of the smooth adjustment of rotation speeds.|
|A good quality electric screwdriver with a powerful autonomous power supply is quite sufficient.|
|It is not necessary to write off already forgotten hand drills. For drilling small holes such a tool will be quite enough, and the adjustment of the rotation speed is not a problem at all. By the way, sometimes even a regular drill bit comes in handy.|
|Standard drill bits with tungsten carbide tips. Frankly, it is not the best choice. such a variant of sharpening will create difficulties in penetrating the toughest layer of the upper tile. Rather, they will be needed to deepen into the wall thickness after the holes in the tile have been made with other drills. designed for a percussive-rotating action.|
|Special lance drills for work with tiles. Very convenient for making small diameter holes (for example, for dowel fasteners). Can have a regular cylindrical shank for clamping in the drill chuck. There are drills and with hexagonal shank, to the size of standard bits. they are convenient to work with an electric screwdriver. Usually enough for a couple dozen holes in regular tile. It is more difficult with porcelain stoneware, because it cannot make more than two or three holes.|
|Special carbide drills with unilateral, sharp-angled grinding. They “dig into” the tiles well, easily pass through the outer, thickest layer. Such drills from a good manufacturer will work a lot.|
|Special drill bits with diamond or corundum coating. Belongs to the category of professional tools, they can cope both with tiles and porcelain tiles. Designed as a hollow tube, which makes drilling easier. there is free exit for waste material. Most commonly produced for larger holes.|
|Similar to those already mentioned, tungsten carbide-tungsten drills. Can be used not only for ceramic tiles, but also for natural materials such as marble, granite, etc.п. They are usually sold in sets for a number of diameters, i.e. they are often purchased by professionals regularly faced with this technological operation.|
|For single works, if it is necessary to make holes of large diameter, it will be more profitable to buy a special drill. “ballerina”. They are inexpensive, but they are quite capable of doing the job in a range of diameters from about 30 to 90 mm. The design is simple. a central drill bit (usually lance-shaped) and a carbide-tipped foot parallel to it. the leg can vary. so you can set the desired radius of the hole.|
|Some models of tile cutters are equipped with a built-in manual “compass”. a device that allows, without resorting to other tools, to cut a hole in the tile. The pattern is similar to a “ballerina” and the rotation is transmitted manually, by means of a crank.|
|For easy and precise drilling of straight holes, the work can be performed with special appliances. jigs. They are fixed on the surface, usually with suction cups, and do not let the drill go sideways, which is especially important when you start drilling.|
|When drilling certain types of tiles the tool gets red-hot very quickly, and the quality of work reduces. You have to resort to artificial cooling with water. To do this, use special blowers that supply water under low pressure to the place of the cut.|
How to drill holes in tiles for dowels?
Depending on the required size holes are recommended to drill with different tools. In some cases you will need to use a drill bit, and in other cases a drill bit of 8-16 mm is enough. But the situation is also possible, when it will be difficult to do without the angle grinder.
To drill tiles for dowels, you need a drill bit for tiles 1-2 mm larger than the plastic insert for the screw. They must first carefully without excessive pressure to drill through the glaze layer. And then gradually all the remaining ceramic up to the wall is cut.
Directly to the wall surface, especially if it is concrete, should be drilled already with another drill a little smaller. Wasting specialized and expensive tools designed for tile is not worthwhile and simply makes no sense.

How to make a rectangular cutout in ceramic tile
Ceramic tile has great strength. It is able to withstand loads of 3 tons per square centimeter, which is much higher than this parameter in concrete and even reinforced concrete. Highly rigid, it does not bend or warp even under very high tensile stress.
Therefore, cutting this material is not quite an easy task, and tools for processing ceramic tiles must be even more durable and hard, made of special grades of steel or with a diamond coating.But today there are many manual and electromechanical devices that allow even in domestic conditions to work with ceramic tiles, cutting it not only along straight lines, but also along curved ones, including the cutting of square, rectangular, round, oval and shaped holes.Below we will consider not the most difficult option: how to make a rectangular cut, adjacent to one edge of the ceramic tile, with special tools.
How to rationally perform a cut in the tile
Let’s assume that we have a water electric tile cutter with a bottom-mounted motor at our disposal. The cooling tank is under the disc, and it is partially immersed in it during operation.A handheld tile cutter will greatly facilitate the upcoming work. It can be used to make an incision in the glaze and with special paws to break the tile along the line of this incision. We also need pliers.Using a marker and ruler, we draw the contour of the planned cut. Then with the water tile cutter and the ceramic tile disc we cut two equal and parallel lines to each other and to the side edges according to the marks.
You can not fear that the disk will overheat or the thermal stress will break the tile. The tool, by capturing water from the container, cools itself and the place of the cut, so the working temperature does not exceed the permissible value.We have to somehow remove the part of the tile between the two slots and the line that connects them. This can be done in different ways. But we will use a handheld tile cutter, because we have it in stock.
Using its cut-off roller, we guide the trimmer trimmer line over the glaze from one to the other of the slots made with the water tile cutter.
You could use the legs of the same tool to break off the “tongue” outlined by the two slits and one notch. But we’re going to do things a little differently.We will use the pliers that we have on hand. Grab their jaws to fill the cutout and press lightly on the handles.
A characteristic sound is heard, and an extra piece of tile is left in the jaws of the pliers, breaking off exactly along the line of the notch.
