How to cut a hole in the roof for a pipe. How to make holes for pipes in different places Features of working on cast iron pipes

There is a need for their wiring through various obstacles, such as walls, floors and other elements of building structures.

But before making holes for the pipe, it is advisable to familiarize yourself with the known methods for implementing such operations, which often affect not only the supporting structures of the building, but also their decoration. In the specific conditions of laying a pipeline, a variety of methods can be used, which are supposed to be considered in our article.

What do you need to know?

The arrangement of holes in load-bearing walls and partitions requires compliance with the known requirements laid down in the current building codes. When preparing them, it is necessary to carefully monitor that such critical elements of building structures and communications are not damaged, which are:

• reinforcing and barrage gratings;
• electrical wiring lines;
• elements of the ventilation system (if any).

In addition, the hole prepared in the wall or floor should provide the possibility of placing a special protective sleeve in it, which, if necessary, can be insulated with any non-combustible material (mineral wool, for example).

General order of work

As for the main working tool, for the purposes indicated by us, a hammer drill is usually used, or a fairly powerful impact drill with a “crown” type nozzle, with which you can make holes of various diameters. The order of their preparation in this case is as follows:

• first, a circle is marked in the right place on the wall, the diameter of which is equal to the cross section of the pipe (together with the sleeve);
• then, using a crown of the appropriate size, a hole is drilled in the wall;
• when the nozzle “slips”, a punch and a hammer will be required, using which it will be possible to destroy the material in a place that cannot be drilled;
• after that, it will be possible to continue working until the finished hole is obtained.

To cut complex holes in certain materials, it will be necessary to prepare a set of crowns of various sizes. For drilling partitions made of drywall, foam concrete, as well as wooden walls, you can use ordinary steel drills.

Note! In the event that it is necessary to drill a hole in concrete, a set of special pobedit drills will be required. With their help, you can work with materials with a thickness of 10-15 cm.

Working with complex coatings

Note! The main problem when working with surfaces finished with tiles (in bathrooms, toilets and kitchens) is the fragility of the facing material, to preserve which it is recommended to drill in a non-impact mode.

When preparing holes of large diameter, it will be possible to use the following techniques:

• use a special diamond "crown" as a nozzle, when using which the drill should work in low speed mode;
• use a special device called a ballerina;
• in order to exclude the possibility of slipping of the teeth of the nozzle or the tip of the ballerina from the surface of the tile, which is smooth and covered with a layer of hard glaze, the latter is preliminarily scratched with a file or sealed with a piece of masking tape.

To make holes in a tile, a simpler and cheaper, but more risky method is often used, which consists in the following. First, using a conventional drill with a diameter of 3–4 mm, several holes are drilled inside the marked circle. Then the gaps between these holes are carefully destroyed and removed with a well-sharpened chisel. And at the end of the work, by means of the same chisel, the edges of the hole expand to a predetermined size.

Preparation of holes in the floor

The procedure for preparing the marked holes depends both on the type of the sexual base itself, and on the type of decorative coating laid on top of it.

Before starting work, first of all, you should decide whether it is possible to remove by cutting or disassembling a section of the decorative coating in the places where pipes are laid. If it is impossible to perform these operations, a hole in the finishing material (in a tile, for example), as well as in the floor base itself, is made using the methods already described earlier.

Cutting a large hole for a chimney is difficult at once. The author of the video shows how to do this by drilling small holes in a circle. Further, this will help to cut a hole of the desired diameter with a crown:

During the construction of pipelines, laying sewers and other works, it periodically becomes necessary to make a hole in a pipe of a certain diameter and shape. On the one hand, this is a simple job that can be done by novice masters on their own, on the other hand, any process has its own nuances and difficulties that it is desirable to know about in advance.

Preparation for work

To drill a hole in a pipe, you need:

• prepare the necessary equipment;
• learn the nuances of the process to avoid mistakes.

Necessary equipment

Cutting holes in pipes is done using:

• a conventional drill or a special professional tool. A special machine is used by people whose profession is related to the installation of pipelines. For home purposes, a drill with a speed control function and a set of various drills is enough;

• vice for fixing the pipe;
• a file with which, if necessary, it will be possible to expand the hole;
• a hammer. With the help of this tool, small diameter holes are punched;
• a wooden block or a homemade template that fixes the drill in a given position.

When cutting holes, do not forget about basic safety precautions. When drilling pipes, it is recommended to wear protective gloves and goggles.

Nuances

1. Determine the type of material used to make the pipe. Each material has its own characteristics that must be taken into account.
2. Determine the wall thickness of the pipe. The larger this parameter, the more powerful the equipment will be required. When drilling a through hole, the outer diameter of the pipe must also be taken into account.

1. To give the drill additional stability, a wooden block or a special template is used:
   • if a bar is used, then it is necessary to drill a hole of the required diameter in it and fix the finished structure at the location of the hole in the pipe. The width of the bar (about 50 mm) will fix the drill and will not allow it to deviate from the given direction;
   • homemade template is also made from a wooden block. The main difference between the designs is that the template contains several prepared holes of different diameters and is equipped with a mounting vice, while the bar must be prepared for each hole separately.

1. when drilling metal and cast iron, the drill may overheat, so it is recommended to periodically moisten it with cold water;
2. only sharp drills, most suitable for a particular material, can be used.

Taking into account all the mentioned nuances will allow you to quickly and accurately make the necessary holes.

Small diameter holes

General drilling pattern

Drilling holes in a metal pipe, including a profile pipe made of metal, is carried out according to the following scheme:

1. the pipe is securely clamped in a vice;

1. if it is required to cut several holes, then the pipe is pre-marked. For this, a tape measure and a marker are used;
2. a prepared bar or template is installed in place of the hole;
3. the drill is wetted in water to prevent it from overheating;
4. drilling is performed.

When working with metal pipes, it is recommended to use the following as additional lubrication and protection against overheating of the drill:

• machine oil for steel pipes;
• soap solution for copper products.

Features of work on cast iron pipes

Drilling holes in a cast iron pipe requires:

• compliance with all safety standards. Since small chips may form during the operation, in addition to protecting the eyes and hands, it is recommended to use a respirator or gauze bandage. In addition, in the room where the work is carried out, there must be high-quality ventilation;
• drilling a hole in a sewer pipe made of cast iron is recommended at low speed drills. The power of the equipment can be gradually increased;
• for drilling, drills with victorious tips are the best choice.

Features of work on plastic pipes

Cutting holes in plastic pipes, such as drain pipes, is the easiest task. This does not require special equipment. All work can be done with a simple drill.

When drilling, there are some features:

• it is necessary to cut holes at the minimum speed of the drill, since under the influence of high temperature the pipe can be deformed;
• if even and neat holes are required, then after drilling it is necessary to refine them with a small file or a sharp knife.

Drilling large holes

Now let's look at how to cut a hole for a pipe in a pipe or how to make holes of large diameters. For this you need:

1. fix the pipe and apply markings on it;
2. according to the scheme described above, drill a hole of small diameter;
3. put on a drill a special nozzle for drilling large holes;

1. insert the center drill into the prepared hole;
2. carefully, first at low speeds of the tool, make a hole of the desired diameter.

When working with nozzles, the drill must be kept in a strictly vertical position. Due to the slightest shift in the equipment, the hole will turn out to be irregular in shape and at an angle.

If a hole with a size of 5 mm to 10-15 mm is required, then the use of special nozzles is not required. It is enough to first drill a small hole, and then use a larger diameter drill to bring the hole to the desired size.

Cutting square holes

Square holes are most commonly cut into square tubing to connect sections into a finished structure. There are several ways in which such holes can be made. The first one is as follows:

1. on the pipe section, the area and dimensions of the future hole are marked;
2. the first stage is cutting a round hole of small diameter according to the scheme presented above;
3. then a drill or nozzle of a larger diameter is selected, which is most suitable for the size of the circle inscribed in the square;
4. a round hole of large diameter is cut;
5. using files of different sizes, a square (rectangular) section is made from a round hole.

The second way is to use a special nozzle instead of files. The preliminary stages completely coincide with points 1 - 4 of the above instructions. The prepared hole requires minimal rework.

The article discusses the method of drilling pipes without special equipment. How the drilling machine works is shown in the video.

So, drilling holes in metal, cast iron or plastic pipes is not a difficult task. If you have an ordinary drill with various drills and nozzles, you can make holes of different diameters and geometric shapes in a short time.

Concrete, as you know, is a hard and durable material, which is why it is very popular in construction. However, due to these properties, its mechanical processing causes certain difficulties. In particular, home craftsmen often face the task of how to punch a hole in concrete?

Concrete drilling methods

The choice of method for obtaining holes in concrete depends on the tasks:

• If you need to get a hole of small diameter, for example, for, then use a puncher with a special drill with a carbide tip.
• If it is necessary to obtain a large diameter, for example, for laying pipes, installing sockets, etc., diamond drilling of holes in concrete is used using special crowns.

Now let's take a closer look at both technologies.

Making holes with drills

Drills or, as they are also called, a screw-shaped rod and, as mentioned above, a carbide tip. The shank can be smooth and cylindrical, designed for impact drills, or made according to the SDS standard, for rotary hammers.

With their help, you can make holes of small and medium diameter.

The instructions for performing this procedure are as follows:

• Before you punch a hole in concrete, you need to outline the place that needs to be drilled.
• Then the tip is inserted into the chuck of a puncher or drill. This sets the depth gauge to the desired position.

In the photo - drilling with a perforator

• Next, the drill should rest on the intended point and turn on the tool. In this case, you need to perform a certain emphasis on the nozzle. Periodically, the drill must be removed from the hole and moistened with water, preventing it from overheating.
• After the required depth is reached, work is stopped.

I must say that you can make a hole with a conventional drill without impact. However, this will require a punch with a hammer. In such a situation, the drill must be periodically removed from the hole and the concrete should be broken with a punch.

Drilling with diamond crowns

Often there is a need to make a large-diameter hole in concrete, for example, to get a sewer or water pipe. Today, there are many companies that provide such services. However, before inviting specialists, you should find out the cost of punching holes in concrete.

It is possible that you decide to perform this operation yourself. To do this, you need the same puncher. The only thing is that you will have to purchase a diamond nozzle-crown.

With this tool, you can make holes with a diameter of 100 mm and even more. Moreover, a properly selected crown will allow you to successfully drill even reinforced concrete structures and concrete of any hardness, with any filler.

Note!
Toothed crowns, when meeting with reinforcement, can jam, while their teeth, as a rule, break.

Thanks to this, it is possible to obtain a hole in any concrete structure. For example, when arranging various wells, people are often interested in how to punch a hole in a concrete ring? A diamond tool can also easily cope with this task.

In addition, there are some other advantages of this method:

• The ability to obtain a hole of the required size of an absolutely round shape.
• There are no shock effects and strong vibrations, so this technology can be used in houses that are under repair or reconstruction.
• There is no loud noise.
• The ability to use when installing air conditioning systems, where sometimes jewelry accuracy is required.
• Ability to drill at an angle, close to walls, floors or ceilings.

Advice!
The price of crowns is usually quite high.
However, if you follow the rules of operation, then the used nozzle can be restored.
There are specialized companies that provide such services.

The principle of drilling is the same as when drilling with auger drills. Including, it is necessary to periodically moisten the crown with water.

If you need to get a hole with a diameter of, for example, 20-50 cm or even more, then the punch, of course, is not suitable for these purposes. In this case, you can drill a hole in concrete using a professional tool.

Powerful equipment is not held in the hands like a hammer drill. Usually it is fixed on the wall with anchors. the lower part rests on the floor, and the upper part rests on the ceiling.

Professional equipment is usually equipped with additional functions, such as water supply to the working area, a dust collector that allows you to perform the procedure without dusting the environment, etc.

Advice!
Diamond nozzles may be needed not only when drilling concrete.
Also an effective method is cutting reinforced concrete with diamond wheels and grinding with diamond cups.

Of course, such equipment is very expensive, therefore, it makes no sense to purchase it for domestic purposes. Therefore, to perform such an operation, it is more advisable to seek help from specialists.

Conclusion

As we found out, in some cases it is quite possible to make a hole in concrete on your own. In order for this operation to take place efficiently and without much effort, you should use a suitable tool for this and follow the drilling technology.

See the video in this article for more information on this topic.

Cutting a large hole for a chimney is difficult at once. The author of the video shows how to do this by drilling small holes in a circle. Further, this will help to cut a hole of the desired diameter with a crown:

Drilling a hole in a concrete wall, even with a drill bit, is not always easy because of the pebbles or rebars encountered.

You can overcome this obstacle with the help of simple tricks: pebbles are broken with several blows of the punch, and the reinforcement is drilled with an ordinary drill.

If you don't have a Pobedite drill, you can replace it with a punch from the New Settler's Dream set.

Inserted into a drill chuck, it takes concrete well.

If the carbide drill is sharpened asymmetrically, then it will drill concrete much faster. It is necessary to mark the hole with a drill with a regular sharpening.

You can also punch a hole in a concrete wall using a punch made from a drill with a diameter of 6-8 mm. Its end is sharpened in the form of a dovetail.

The drill is struck with a hammer and constantly turned.

It only takes a few minutes to punch a hole with this tool.

When drilling holes in concrete or brick, the drill bit will last longer if it is periodically moistened with water.

An elastic plastic bottle can be used as a water reservoir.

When drilling holes in the ceiling, crumbs of plaster flying from the drill get into the eyes, behind the collar of the clothes, under the sleeves. To avoid this, it is enough to wrap a funnel made of spring wire with a transparent plastic film and put it on a drill.

If you have outweighed the ceiling lamp, the metal hook remaining in the ceiling can be easily disguised using a plastic cup, a button to match the color of the ceiling and a pharmaceutical rubber band.
When hanging a chandelier, it is often necessary to punch a hole in the ceiling to install a metal hook. To prevent the fragments and plaster from falling on the floor, you can use an old rubber ball. The ball must be cut in half, make a hole in one of the halves and put it on a punch or jumper.

If you are going to make a hole in a stone or concrete wall, tape it under a sheet of thick paper folded at an acute angle - it will protect the walls and floor from dust and debris.

There are several ways to fix a screw in a concrete wall.

Wooden cork is a true, but far from the only and not always the most suitable option.

It is much better to stuff the hole tightly with nylon (crushed old nylon stocking) and melt it with a red-hot nail. While the capron has not cooled down and hardened, screw in the screw.

Kapron hardens quickly and will firmly hold the screw in the socket. In the hardened capron, the thread from the screw remains for a long time.

Therefore, this method is especially convenient in cases where the screw has to be unscrewed from time to time, and then screwed again. to the same nest.

A wooden cork can be successfully replaced with a loop of two-wire electrical wire in PVC insulation, the ends of which are cut flush with the wall.

You can also apply the technique that electricians use to install rollers: wrap the screw around the thread with soft wire (let its ends protrude a little) and firmly insert it on the liquid alabaster into the drilled hole.

After the alabaster has hardened, the screw will be fine hold on. If necessary, it can be turned out - cutting from the wire will remain in the hole.

As a dowel, you can use a piece of copper or aluminum tube with a longitudinal slot. It is crimped, inserted into a hole drilled in the wall and a screw is wrapped.

If the wall is made of sufficiently strong concrete, then you can do it quite simply: drill a hole whose diameter is smaller than the diameter of the screw and then screw the screw into it with force, it will hold firmly without any additional devices.

If it is necessary to drill a through hole in the wall, and the length of the drill is not enough, then this operation can be performed in two steps: on one side and on the other side of the wall. Having drilled a hole at the intended point, place a magnet or a metal rod in it.

Then use the compass to find the drilling point on the opposite side of the wall. The use of a magnet is preferable, as it will prevent the compass needle from erroneously pointing at the wall reinforcement.

Heavy shelves for greater reliability can be hung on bolts.

Holes are knocked out in the wall with a margin and bolts are cemented in them, leaving the thread to protrude to the desired length.

The shelves are fastened with nuts, which, if necessary, are recessed and puttied.

When embedding in a wall (using concrete or plaster) a bolt with a head inward and a thread outward, bend its shaft at an angle of about 30 °.

This will increase the stability of the bolt.

You need to hang something from the ceiling, for example heavy chandelier. How to do it? We offer this option.

Insert a threaded metal sleeve into the hole in the ceiling.

2-4 holes should be drilled in it, in which steel fingers should move.

We screw a pointed bolt into the bushing from below. He will spread his fingers, and they will forcefully rest against the walls of the hole, due to which the device will be firmly fixed in the ceiling.

The suspension will be even more reliable, although it will require more work if you drill not one hole, but two at opposite angles to each other, as shown in the figure. Two rods are inserted into the hole and fastened together. The pendant is ready.

Little hint. Do not rush to cover the vacated hole in the concrete wall with wallpaper. Put some metal object into it: a ball, a screw, a pushpin. With the help of a small magnet, you can always find the old hole so as not to drill a new one.

The walls of a standard sanitary block are made of asbestos-cement sheet. The screws don't stay in it. To hang shelves, drill holes in the wall and cut threads into them. Mounting bolts must be tightened without much effort.

Fixing a bolt in a thin wall requires preparatory operations, namely: you need to take a soft metal tube along the diameter of the bolt and make a cross-shaped incision at one end.

Then drill the wall according to the diameter of the bolt head and insert it into the hole with the attached tube. When tightening the nut, the head of the bolt (preferably tapered) will expand the notches, and the bolt with the tube will be securely fixed in the wall.

Another way. Instead of a tube, an internal clamping washer can be used. Its shape is visible in the figure. It can be made from tin or aluminium.

Using this method of fastening, you need to be accurate in determining the size and shape of the hole in the wall. It is better to make it rectangular, but it can also be round.

The clamping washer can also be made in the form of a cross-shaped clamp, bent in such a way that its short legs hold the nut on one side of the wall, and the long legs serve as a washer on the other. sides.

You can also fix the bolt in the wall with a flat pin, if you proceed as follows: drill a hole along the diameter of the bolt head, cut off part of the head, then insert it into the hole and, holding the bolt with pliers, wedge it with a pin.

The rest of the head will push to the side and catch on the wall. A nut with a washer will make the pin invisible.

Another way of fastening to a thin wall, to the reverse side of which there is no access. At the end of the threaded stud, one or two strips are hinged.

They are inserted into the hole, the bolt is shaken, and the slats, turning installed parallel to the wall. It remains to screw the nut and cover the hole with alabaster.

If you need to drive a nail into a thin wall, keep in mind that a nail driven into a plywood or dry plaster wall will hold better if it is bent into an "M" shape.

The smoke exhaust structure is an element that is characterized by an increased fire hazard, therefore, solving the problem of how to make a hole in the roof for a pipe should be approached responsibly. It is also important to protect the roof from moisture penetration, otherwise its service life will be significantly reduced.

Corrugated roofs deservedly enjoy the trust of the owners of private houses, because they have:

• a light weight;
• long operating period;
• appearance, reminiscent of the relief of ceramic tiles.

Decking is thin, durable and corrosion-resistant metal sheets that are coated with paint and pressed into the desired shape. After installing stoves or heating boilers, it is necessary to make a passage for the chimney through the roof structure.

Every homeowner must understand how to get the pipe through the roof from the corrugated board. Even if this work is done by professionals, it will not hurt to control the result.

Types of chimney structures

The chimney pipe is used to remove smoke and combustion products into the atmosphere. It is a hollow cylinder.

To organize this process, stove-makers build:

1. brick chimneys. The smoke exhaust system is created from heat-resistant bricks, which are produced using a special technology specifically for arranging furnaces. The pipe in this case has a section of a rectangular or square shape. This method of getting rid of smoke is expensive, but it is more durable and safer. Its main disadvantage is the porous inner surface - for this reason, soot and dust are deposited on it in large quantities. If the pipe is not cleaned regularly, soot layers can completely or partially clog it, the traction force will decrease, and the risk of fire will increase. The process of how to bring the chimney through the roof from corrugated board is complicated and therefore it is better not to do this work with your own hands - it should be done by experienced stove-makers.
2. Metal chimney systems. To assemble the structure of the required configuration, you need to purchase stainless steel pipes with the addition of zinc or molybdenum. Then insert the segments one into the other - you will need straight tubular products, clamps and bends. Due to the presence of a slippery inner surface, soot cannot accumulate, which means that smoke can freely move up, outside the house. The disadvantage of this method is that the metal does not retain heat well enough compared to the brick, as a result of which condensation collects on it, since there is a temperature difference between the pipe and the air outside. The metal chimney structure can be easily brought to the roof, because it consists of individual elements.

Chimney outlet - how to cut a hole

Before cutting a hole for a pipe in a profiled sheet, you should choose a convenient place for this. The decisive factor here is the location of the furnace unit.

According to professionals, the chimney should be placed strictly vertically, taking into account some of the nuances:

1. It is advisable to make a hole for the exit of the chimney pipe at the highest point of the roof, which means closer to the ridge. The optimal distance from it to the chimney is 50-80 centimeters.
2. Before making a hole for the pipe in the corrugated board, you should make sure that it does not fall on the elements of the rafter system. To get around them, bends are used, with the help of which they set a turn of 45 or 90 degrees.
3. The length of the chimney segments is selected so that the joints between them are below or above the intersections of the roof and ceilings, otherwise a quality connection will not work.
4. It will be possible to achieve the required level of thrust if the height of the chimney structure exceeds this parameter at the ridge by 1–1.5 meters.
5. To make sure that the exit point is determined correctly, it is circled on the roof with a marker and the temperature in it is checked at the end of the day. The pipe must be in the cold zone at all times.

Preparatory measures for the removal of the chimney through the roof

There is the following technology, how to make a hole in a profiled sheet for a pipe:

1. First, a permanent marker marks the place of its removal to the roof.
2. The size of the section of the chimney elements is selected taking into account the recommendations of the manufacturer of the heating unit. The thicker and higher the pipe, the easier the smoke comes out of the stove. The main thing is that when connecting between the elements there is no gap.
3. A hole is cut out with a grinder with a thin blade for metal work, stepping back a few centimeters from the drawn line. The corrugated board must be cut carefully and slowly so that the edge of the cut is without jags.
4. Short cuts are made in the corners of the holes so that the edges of the corrugated board are bent up.
5. A similar passage is made in the ceiling. Then a metal box is installed, designed to connect the pipe to the rafters. The chimney is laid through the hole inside the box.
6. Hydro and vapor barrier material, as well as insulation, are removed from the outlet cut out in the roof.

For cold areas, where the thickness of the heat-insulating material is more than 15 centimeters, it is necessary to use sandwich pipes with two layers of metal and a layer of insulation between them.

How to remove a pipe on a roof from corrugated board

When the preparation for how to bring the chimney through the corrugated board is completed, it should be properly connected and the chimney put into operation, for which:

1. It is necessary to insert the pipe through the hole in the box and direct it towards the roof, and fix the edges of the waterproofing material with adhesive tape on the surface of the chimney.
2. Expanded clay is densely poured into the box or mineral wool is used.
3. A rubber or silicone seal is put on the pipe to protect the outlet from water seepage. To improve waterproofing, glue the sealant to the corrugated board using a fire-resistant sealant.
4. The smoke exhaust structure is extended in segments to the required height, while the joints are tightened with galvanized steel clamps.
5. An external apron is installed, having the color of the roofing, which will close the box and rubber seal.

When bringing the chimney to the roof, it must be remembered that neglect of such work can result in a fire and material losses.

When installing plumbing, it may be necessary to drill a hole in the tile. In the article we will analyze the various ways to perform this work.

Repair work may require making a hole in the ceramic tile for a pipe, sink, outlet, etc. The tile may already be laid on the surface, which complicates the cutting process. How to proceed in this or that case, we will analyze in the article.

Preparatory work

It is difficult to hold the tool in the right position when drilling tiles due to its smoothness. Therefore, before starting work, you need:

• mark the location of the future hole;
• tape around the markings with masking tape.

This will avoid scratches on the surface, chipping and slipping of the drill.

How to make a hole

Depending on the required diameter of the hole for a pipe, sink or just a dowel, one or another drilling option is selected. Some of them can only be used if you need to get a hole for a nail.

Options

The principles of cutting tiles are similar in all cases, but it has its own characteristics depending on the selected tool. The main thing is the observance of safety regulations.

Drill bit for ceramics

Let's look at drilling options:

1. Gradual increase in drill diameter. The advantage is that the risk of chipping is minimal. Stages:

• We take the smallest diameter of the drill.
• Drilling should be slow, avoiding overheating of the drill. To do this, moisten it with water.
• After deepening into the surface, when the tool does not slip so much, spray the tiles with water as well.
• After getting the first hole, take a drill of a different, larger diameter.

1. When there is only a thin drill. Stages:

• Drill several holes along the contour of the future hole for the pipe.
• Next, without making much effort, knock out the center.
• Grind existing irregularities using sandpaper.

To begin with, take a coarse-grained and gradually reduce the graininess of the sandpaper. This will achieve the smoothest possible inner surface.

Carbide drill for concrete

For drilling tiles, a carbide drill is also used. Sold in hardware stores as a drill with a pobedite tip. When working with it, you should adhere to the following rules:

Crown with diamond coating

The diameter must be selected according to the size of the future hole. Drilling order:

Circular drill for tiles / ballerina

There are special nozzles on the market for making holes in tiles - ballerinas. In fact, this is a drill with an additional cutting element.

1. In the center of the future hole, make a recess in any way.
2. Secure with a central drill in the hole made.
3. Work at the beginning with a drill at low speeds. Gradually deepening, the side nozzles will begin to scratch the tiles.
4. When half the work is done, turn the tile over and follow the same steps until the center falls out.

Using self-tapping screws with an LM tip

In the case when a hole needs to be made urgently, and there is no drill with nozzles or drills at hand, self-tapping screws with an LM tip are used. Operating procedure:

1. Outline the diameter.
2. We screw in the screws along the inner contour at small intervals and unscrew them.
3. We squeeze out the center and clean the bumps with sandpaper.

Bulgarian

To make through holes in a tile before installing it or curly cutting, an angle grinder is most often used. How to use the tool:

1. Outline the contours.
2. Install a diamond-coated dry cutting blade.
3. Gradually make a hole. The tool should be smoothly guided away from you. Take care of your fingers. Hold the tile so it doesn't slip off.

Work is performed on the front side of the tile to avoid chipping.

jigsaw

It is used to make holes of various shapes at the edge of the tile or in its center.

1. Markup. Made from the front.
2. Need to cut from the edge of a tile? You can get to work.
3. Need to make a hole in the center? A small hole is made with a drill to thread the cutting area of ​​\u200b\u200bthe jigsaw into it.
4. Set the tool to the edge of the cut.
5. Slowly, we lead the jigsaw along the markup.

Under the pipe

All options considered are suitable for making a hole. An exception is the method of drilling with a drill bit in ceramics with a gradual increase in diameter, since there is no tool of this size.

For the great snipe

You can make a hole under the dupel in almost any way considered. However, options such as the use of a jigsaw and a ballerina are considered inappropriate in this case. It is best to use a drill for ceramics or tiles.

How to cut under the faucet

The size of the hole for the mixer is smaller in diameter than for the pipe. However, the drilling options are identical in both cases.

Under socket

Sockets come in different shapes. Therefore, when choosing a tool, you should build on it. If the shape is round, then all options are suitable except for a gradual increase in the size of the ceramic drill. If a square, the best solution is a jigsaw.

Do-it-yourself hole with improvised means

A hole at the edge of the tile can be made without using the above options. You will need a glass cutter and tongs/pliers. Stages of work:

1. Marking the future hole.
2. Soak the edge in warm water for a few minutes. This will soften the ceramic.
3. With a glass cutter, without lifting the tool from the tile, draw a line along the markup. You need to make a fairly deep furrow, so do the work with effort, but carefully.
4. It is necessary to tap along the cut line. This will make the groove deeper.
5. Use tongs to break off a small piece of the tile until the excess material is completely removed.
6. If there are irregularities, use fine-grained sandpaper to sand the edge.

How to drill a hole in a large diameter tile: work steps

If you need to make a hole of a large diameter, use the following scheme of work:

1. Mark center.
2. Mark the diameter.
3. Insert a ceramic drill into the drill. As an alternative, a concrete drill, but of the smallest diameter.
4. We make holes on the back of the tile around the entire circumference. The distance between them is minimal.
5. Carefully punch out the center.
6. Remove bumps with pliers or wire cutters.
7. Sand the inner diameter with fine grit sandpaper. An alternative to sandpaper is an abrasive stone.

Do not use an impact tool, as the risk of splitting the tile web increases. Ceramics, although hard and rigid, is quite brittle.

In order not to form chips that spoil the appearance of the tile, you must adhere to the following rules:

1. Careful choice of tool, namely its cutting part. It is necessary that the glazed layer is gradually destroyed, and only then the ceramics.
2. Failure to meet performance standards. Tiles are placed on a solid surface horizontal or vertical.
3. Excessive pressure on the instrument. The selected drilling option should be focused on cutting the ceramic sheet without additional pressure.

Depending on the purpose of the hole and the available tools at hand, the drilling method is selected. However, when performing work, it is necessary to observe safety precautions and follow the recommendations to reduce the risk of chipping.
