When improving an apartment, it becomes necessary to mount all kinds of objects on the walls and ceiling - photographs, paintings, lamps, mirrors, curtains, shelves, TV, baseboards and much more.
In order to hang a photograph or a small painting, of course, you should not drill into the wall. It is enough to hammer in a small nail. Not every carnation is suitable for this task. It is best to use dowels - nails from the mounting brackets used to secure computer computers to the walls. network cables. These cloves are of sufficient length, thick and hardened. It turns out to score even in concrete wall.
Performing the operation of drilling holes in walls with modern equipment with power tools will not present any greater difficulty if you know how to drill correctly. It will save you from unnecessary cleaning and keep your property intact if you use a jig for dust-free drilling.
How to drill a wall
A better tool than a hammer drill for drilling holes in brick and concrete walls has not yet been invented. But rarely does anyone have the luxury of having such an expensive tool on their household. Usually buy an electric impact drill.
Drill selection
When purchasing an electric drill, you need to be guided by the following technical characteristics.
The power of the drill must be at least 600 W. Revolutions up to 2500 per minute and the possibility of them smooth adjustment from zero to maximum. The presence of reverse rotation (switch for the direction of rotation of the drill clockwise or counterclockwise). The best chuck is a quick-release chuck; you won’t have to waste time clamping drills and constantly searching for a lost key. The diameter of drills clamped in the chuck is up to 12 mm.
The presence of a switchable hammer drilling function. Of course, when this function is enabled, the drill will not become a full-fledged hammer drill, but drilling walls will be much easier and faster, and here’s why. Brick, cement and concrete withstand static load - pressure very well. But they are easily destroyed by dynamic influences - impact. Karatekas, with a strong blow, easily break a brick in two with the edge of their palm. When drilling with a drill without a hammer function, there is simply pressure from the drill and it is difficult for the cutting edge to catch on to the material, so drilling is slow and the drill becomes very hot due to friction. Drilling with impact is completely different. Upon impact, the drill punctures a part of the material with its cutting edge, and, falling with an impact into the formed recess, breaks off a portion of particles of the material. Something like chiselling is happening.
Drill selection
Walls made of wood, plasterboard, and foam concrete can be successfully drilled with an ordinary drill. For walls made of brick, stone or concrete, you need a carbide drill. It differs from steel in welded on regular drill cutting edges made of carbide material, usually win. Less commonly, artificial diamond.
The pobedite insert is clearly visible at the end of the top drill. It is enough to have 2 Pobedit drills with a diameter of 6 and 8 mm on the farm.
Using drills with pobedite surfacing, you can drill a hole no more than 10-15 cm deep. For drilling to greater depths, for example, to drill through a wall, use a drill. Drills for drilling brick and concrete walls are up to one meter long and are designed for drilling holes only with a hammer drill. Even the cutting edges of the drill are made not sharp, but rounded to increase their wear resistance. A drill with a hammer function can also be successfully drilled with a drill.
Drills come with a shank diameter of 10 and 18 mm, with special grooves of the SDS+ or SDS-max standard for fastening, but they also clamp well in a regular jaw chuck. The standard and diameter of the drill are stamped on its shank.
If you need to drill through a thick wall, for example half a meter, then the passage is carried out in several stages with drills of the same diameter, but of different lengths. This is necessary for safety and faster drilling. First, drill the wall with a 20 cm long drill to a depth of 10-15 cm, then with a longer drill to a depth of 30-35 cm and finish drilling with a 50 cm long drill. The drill for such work must be powerful enough. Of course, the drill is not designed for such a load and its use is permissible only in exceptional cases. To perform this type of work, it is better to rent a real hammer drill.
How to drill a wall
Before you start drilling a wall or ceiling, you need to make sure that there are no holes in the plaster under the intended place. electrical wires or other cables. Otherwise, you can damage the electrical wiring and get under voltage yourself.
How to avoid getting caught in a wire
It is necessary to inspect the wall for the presence of a switch or socket. Usually, wires extend from them upwards in a vertical direction to distribution box. But verticality is the ideal case. This rule is rarely observed in practice by electricians, saving wire, often hidden wiring laid diagonally. Here's an example of this. When I made repairs and moved the counter to another place, after removing the old wallpaper the following picture opened. You can clearly see how the wire leading to the meter was laid.
But still, the wire will run from the switch to the nearest box. The wire will also go from the chandelier to the nearest box.
Typically the wires are recessed to a depth of no more than 10 mm. To check, use a blunt instrument, such as a screwdriver, to dig into the wall to this depth. If no wires are found, then you can start drilling. And yet, just in case, up to a depth of 20 mm, you should not press too hard on the drill and after deepening every couple of millimeters, visually check whether the wire is caught.
There are special devices that allow you to determine the location of wires in the wall. Here are some of them that are not expensive, made in China, but nevertheless work well. It also has a metal detector function, which allows you to identify the location of metal reinforcement in concrete walls. The device allows you to find copper electrical wiring at a recessing depth of up to 10 mm. Electrical wiring made of aluminum wires can only be detected in metal detector mode.
Wiring detection is indicated by flashing LED and intermittent sound signal. In metal detector mode, when detected, the diode lights up constantly and the sound produced is continuous. There is a sensitivity regulator, the finder is powered by a Krohn-type element. Such a device is especially necessary when installing suspended and suspended ceilings, because load-bearing structures They are mounted on self-tapping screws near the ceiling, exactly where electricians usually lay the wiring.
Drilling holes in reinforced concrete
Brick walls can be drilled with a Pobedit drill without much difficulty. We decided on the location, attached the jig and, pressing hard on the drill, drilled a hole. It happens that you come across burnt bricks in the wall, which drills more slowly, the dust is not red, but black. The main thing is to drill at low speeds (200 - 400) with the impact mode turned on, pressing harder on the drill handle, and make sure that the drill does not overheat.
I bring to your attention a great video where you can see how a brick wall is drilled using an ordinary drill with a hammer drill function and a drill with pobeditovy surfacing. A hole was made in the brick wall for a box to install an internal electrical outlet.
As you can see, drilling a brick is not at all difficult. Be careful When drilling for a long time, the drill heats up to high temperature And If you touch it, you can get a severe burn. It is necessary to periodically stop drilling and dip the drill in water.
Unless the concrete wall or ceiling is made of 600 or 500 grade cement, it drills just as well as brick. In domestic construction, only grade 400 cement is used. In old houses, sometimes there are columns and ceilings made of high-strength concrete. They are very difficult to drill and take a long time.
In the production of concrete blocks and wall panels for strength, they install iron reinforcement welded together mutually perpendicularly, which is corrugated rods with a diameter of 8-15 mm, and add granite crushed stone. A pobedite drill is not able to overcome such an obstacle. But there is a simple solution. When, while drilling, the drill suddenly stops going deeper, it means it has encountered reinforcement or granite. The reinforcement can be successfully drilled with an ordinary drill. If you don’t have a simple drill on hand and it is permissible to move the location of the hole, then you can move it diagonally up or down. Granite pebbles in concrete crumble when struck with a drill or narrow chisel inserted into a hole with a hammer. After each blow, to prevent the tool from jamming in the concrete and to make the work go faster, it is necessary to turn it a quarter turn. After removing the obstacle, drilling continues with a Pobedit drill. For a drill with a hammer drill, granite stones are not an obstacle and can be drilled successfully.
Drilling tiles
To drill into tiles with a carbide-tipped drill not specifically designed for tiles, it is necessary to first remove the glaze after marking the drilling point.
This is done very simply, with a core, and if it is absent, you can use an ordinary self-tapping screw or even a thick nail with a sharp end to chip off the glaze with very light blows in the place of the future hole and then drill as brick wall at low speeds.
Drilling large diameter holes in the wall
With equipment ventilation ducts and hoods, it becomes necessary to make a large diameter hole in the wall, for example 18 cm. Sometimes you want to hide it in the wall electric meter, and then you need to make a niche in the wall.
At home, this problem can be solved using a carbide drill. The outline of the future hole is drawn on the wall with a pencil. WITH outside From the marking line, holes are drilled with a carbide drill with a diameter of 8-12 mm with a distance between the edges of the holes of about 10 mm. For a hole in the wall with a diameter of 18 cm, you will need to perform about 30 drillings with a drill diameter of 10 mm. Next, a sample of the wall material is made using a chisel and hammer. With a smaller drill diameter, the edges of the hole will be neater, but you will have to drill more holes.
If the wall is thick and the length of the drill is not enough to achieve through drilling, then you can drill in two stages.
If it is possible to drill a wall on both sides, then first perform drilling as described above on one side of the wall, then in the geometric center of the resulting sample, a hole is drilled in the wall to reach out, that is, through. Relative to the resulting hole, markings are made on the opposite side of the wall and the operation is repeated.
If it is not possible to drill a thick wall on both sides, then you will have to do drilling and sampling in two stages. From the marking line on the outside, another line is drawn at a distance sufficient so that after the first sampling in the wall and further drilling, the drill can go deeper into the made niche without touching the edges of the wall.
To reduce the labor intensity of the work, it is better to immediately purchase a drill of sufficient length.
Drilling depth limiter
To control the depth of the resulting hole during the drilling process, you can put a piece of cambric (tube) of the required length on the drill bit until it stops in the chuck.
If you do not have a suitable cambric on hand and you need to drill a small number of holes, then you can use ordinary PVC insulating tape, winding several turns of it. This simple device will speed up your work and save you from having to stop drilling to measure the depth of the hole.
Jig for drilling holes without dust
Due to the heterogeneity of the walls, especially those made of brick, the drill often “leads” away from the intended place and if there is more than one hole, then the suspended shelf does not hang horizontally or, even worse, it is impossible to hang it, since the installed dowels do not coincide with the mounting ones loops. You can use a jig in the form of a sheet of plywood with a pre-drilled hole, but when drilling due to vibration it can also move and again the result will not be what was expected. But there is simple technology, allowing you to drill two or more holes strictly in specified locations.
Precise hole drilling
It turns out that the problem can be solved very simply by gluing a sheet of any sandpaper with glue or double-sided tape to the entire area of the side of the conductor that is attached to the wall. At the same time, the adhesion of the jig to the wall surface increases many times over, and during drilling, the specified accuracy of positioning of the jig is ensured. The hole will appear exactly at the marking location.
Depending on the weight of the product and the density of the wall, you have to drill holes for dowels of different diameters, usually 6 or 8 mm. For the versatility of the jig, it is necessary to drill several holes of the desired diameters with an ordinary drill.
To top it off, attach a plate to the end of the base of the conductor at a right angle. Thanks to this modification, most of the drilling products will remain on this shelf, which will prevent contamination of the wallpaper and reduce the scattering of dust in all directions.
The proposed device is also indispensable when drilling holes for attaching skirting boards. Drill a hole in the jig at a given height from the shelf. When drilling, place the shelf on the floor and all the holes will be exactly on the required height from the floor, which will guarantee a tight fit of the baseboard to the floor surface.
Sometimes you have to hang a product on the wall, for which you need to drill several holes in the wall and maintain the distance between them with greater accuracy. If the wall is brick and plastered, then it is impossible to perform accurate drilling without a jig.
To make a jig for precision drilling, a board, sheet of plywood or metal is suitable. After marking in the sheet, it is drilled with an ordinary drill required quantity holes. Consider the case for fastening the product with two screws. One hole is drilled with a diameter equal to the diameter of the drill that will be used to drill the wall, the second with a diameter equal to the diameter of the self-tapping screw. After the jig is made, the first hole is drilled in the wall using the jig for the precision drilling described earlier, and a dowel is driven into the hole.
The conductor is screwed to the wall with a self-tapping screw into the hammered dowel and leveled using a water level so that drilled holes were on the same horizontal line.
Thanks to the use of a simple jig, which can be made in a few minutes from any available material, the holes were created exactly at a given distance from each other.
Using the same technology you can drill and a whole series holes at a greater distance from each other. In this case, the outer holes are first drilled using the technology described above, the jig is screwed with two outer self-tapping screws, and then all other holes are drilled.
The proposed options for conductors are convenient when renovating an apartment, when dirt is common everywhere.
However, when the renovation is completed and the place is clean, drilling becomes stressful. You don’t want to stain your carpets and furniture with concrete or brick chips and dust.
Drilling without dust
When drilling walls, especially the ceiling, flour and grains of sand from the drilled material scatter throughout the room. This happens because an impeller is installed inside the drill to cool the engine, which, rotating, sucks air into the drill body from the side of the handle, and throws it out heated in the chuck area. This measure makes it possible to make a drill of greater power with small dimensions and protect the drill mechanism itself from dust. And the question of how to protect your home from dust when drilling is left to the owner to decide. I present simple design allowing you to drill without dust.
The drilling jig for dust-free drilling is a modified previous version, but the shelf is replaced by a part cut off from plastic bottle. A piece of 9-11 ply plywood measuring 80x150 mm is cut out, and a hole with a diameter equal to the diameter of the drill plus 1 mm is drilled at a distance of 30 mm from the edge along the center line. On the side where the sandpaper will be glued, a trapezoidal cut is made with a depth of 2-3 layers of plywood. The sample will serve as a kind of air intake during drilling.
A part is cut off from a plastic bottle so that the remaining part can be attached to the conductor. The width of the base of the conductor is selected based on the size of the bottle. I took a square bottle, but any 1.5 liter bottle will do. Insulating tape is wound onto the threaded part of the neck of the bottle until a size equal to internal diameter suction pipe of the vacuum cleaner. When the bottle is bent, holes are formed to form the required configuration. We close them with pieces of the remaining plastic from the bottle and secure them with a stationery stapler. You can close them with tape. There is no need for tightness here. Gaps of a few millimeters will not matter, since the suction power of even a low-power vacuum cleaner is excessive.
Then, using a furniture stapler, the formed part of the bottle is secured along the perimeter of the end of the base of the conductor, on the side where the sandpaper is not glued. We make a hole in the bottle for the drill. It is better to use the melting method, since the edges forming the hole will become thicker and last longer. I melted it with a soldering iron. You can melt a hole by heating it gas stove until red with a nail.
We connect the vacuum cleaner, turn on the minimum suction power, and do test drilling.
The result will make you very happy. You will not find a single speck of dust in the circle or brick flour on the drilling surface!
IN modern buildings As a rule, the walls and ceilings are concrete. Sooner or later, the need may arise, for example, to hang a lamp shelf or, during renovation, to sheathe the walls with plasterboard, then the problem arises of how to drill through a concrete wall with a drill.
Difficulty in drilling can arise due to a number of reasons. First, the structure concrete panels is heterogeneous and their composition includes iron reinforcement, cement-sand mortars and crushed stone, which makes drilling difficult. Secondly, concrete has high strength and is very difficult to process.
How are concrete walls drilled?
Before starting work, it is important to decide which drilling device is best to do the job. The choice, of course, is small, since there are two types of wall drilling:
- drill;
- hammer drill.
A hammer drill will do this job better, since its function is precisely to punch holes in concrete or stone surfaces. Using this tool, you can make holes with a large cross-section, but even the highest quality impact drill is not capable of more than 12 cm.
But when do you need to drill? foam concrete walls, a drill will be optimal, since a hammer drill will simply crumble the surface.
When working with concrete walls, you absolutely cannot use a hammerless drill, because it will be pointless, and you can ruin the tool.
When you only have to make a few holes and you don’t have a hammer drill, you shouldn’t buy one because of this; you can get by with a drill. If you have to great job, then buying a rotary hammer is inevitable.
In the case when you still need to work with a drill, it is important not to forget that you need to use a Pobedit drill for concrete and with a tip coated with a carbide compound.

Diamond drills and other devices
On store shelves you can sometimes find a model of ring drills with a diamond tip. Such products are intended for drilling huge holes with a cross-section of up to 25 cm. It is important to note that such devices are expensive, therefore for home use they are not worth purchasing.
If it becomes necessary to make a hole for a socket or switch, you can use crowns designed for drilling concrete. The cutting part around the circumference has universal solderings made of carbide metals.
Such elements have a cross-section from 35 to 120 mm, but products with a cross-section of 68 mm are in great demand, since this is what sockets and switches have. If you are drilling with a crown, it is important not to forget to turn off the hammer drill’s impact function. This device drills holes with a maximum depth of 15 cm. If greater depth is required, it is recommended to use an extension nozzle.
Similar bits are also sold for electric drills. They differ from the previous ones in that instead of soldering, they are equipped with a tungsten carbide alloy coating. The advantages of such a device are that if concrete walls are lined tiles, then there is no point in replacing the nozzle, since it works well on concrete surfaces. But we must not forget that such devices can be used for drills with a power above 1000 W.
Most often, drills are used to work with a rotary hammer, the cross-section of which ranges from 4 to 80 mm. Many people are faced with the problem of choosing the correct drill diameter. But the smartest thing to do when buying a hammer drill is to also purchase a set of concrete drills. But a high-quality kit costs a lot of money, and therefore it is necessary to select the same cross-section as that of the dowel intended for this model.

Everyone knows that a concrete wall and all similar structures have strong qualities and are difficult to drill, since most often during work you can stumble upon crushed stone included in concrete composition, from which wall and ceiling structures. Holes in concrete slabs during construction are carried out quite often:
- during finishing works;
- when installing built-in furniture;
- when installing air conditioners;
- when installing electrical wiring;
- when installing plumbing fixtures.
During the minor household repairs You can get by with a simple electric drill that is not equipped with an impact function.
To do this, during the process of introducing a Pobedit drill into a concrete surface, you need to periodically crush the concrete with a metal punch, which must correspond to the cross-section of the hole. It is used when, while drilling, an electric drill starts to get stuck in concrete. Then they place the punch in the hole and hit it, using a hammer or sledgehammer, which helps to crush compacted areas and penetrate deeper. But you need to turn the punch slightly, and then you can start working with a hammerless drill again.
These manipulations should be continued until the holes reach the desired depth. This method is very time-consuming, but suitable for several holes.
Of course, you can also use universal drills with diamond tips. They will do an excellent job with metal, crushed stone, as well as concrete structures. But it is important to note that they are only suitable for an ordinary drill or a device with the vibration mode turned off. When using diamond drills, you should remember that they require cooling during operation.
But good effect Drilling can be achieved using a hammer drill. Its advantages in combining functions rotational movement with reciprocating movement. When drilling with such a drill, the tip of the drill is able to break the concrete composition, and the drilling process will be the least labor-intensive.
Concrete structures, walls and ceilings are not uncommon in our houses and apartments. In multi-story construction, they are generally used with particular frequency, since houses with concrete walls are the most reliable. The reliability of concrete is determined by the good strength of such a material, which is achieved by using the right components concrete mixture and quality work done on its construction.
And so we are proud of our strong walls. But usually it becomes necessary to drill a hole in this very wall. Moreover, this may be needed quite often, for example:
- when finishing walls and ceilings;
- during the installation of air conditioners;
- when installing plumbing;
- when building furniture;
- when working with electrical wiring and its installation;
- the need for holes for mounting under a picture or other interior items.
As you can see, there are many reasons to drill into a wall. The main thing is not only to do the job well, but also to make your life easier by using the right good tool. Which one can you choose to drill concrete?
It would seem that what’s wrong with this: just take a regular drill and drill. But no, in fact, many difficulties may arise in the process of completing this task. Firstly, concrete walls are very strong and difficult to pick up, and secondly, their structure is heterogeneous, and you can easily risk falling on crushed stone or a piece of reinforcement. Stuck with the usual concrete wall You can end up drilling nothing for a long time.
How to drill a hole?
The answer to this question will not be too complicated. The fact is that drilling a concrete wall, as mentioned above, is an extremely difficult process. To solve this issue, it is worth using one of two types of tools: either a hammer drill or a drill.
Both will be good in certain conditions. I'll explain why. It is best, of course, to use a hammer drill: it is intended specifically for concrete walls and common practice is to use it. After all, a hammer drill easily breaks through both stone and concrete surfaces. Another advantage is the ability to drill large-diameter holes, which a drill cannot do.
But, if you have a wall made of foam concrete in front of you, or you need to drill several small holes, a drill will do just fine. IN in this case a hammer drill can split the surface of the wall, which is not very successful. But, as already mentioned, on big holes do not count, only with a diameter of no more than 12-15 cm. In addition, drilling a concrete wall has its own nuances, which we will consider below.
How to drill through a concrete wall with a regular drill?
Let's talk a little about drilling a regular drill. So, let's start with the fact that the usual one is unlikely to work here. Those. theoretically this is, of course, possible. But in practice it is extremely difficult. In this case, it is necessary to use a special Pobedit drill for working on concrete with a tip coated with a hard alloy composition.
The best way is to use a special impact drill. How is it different from the usual one? The fact that in such a drill the movements of the drill are carried out due to special ratchets with teeth interacting with each other. This type of drill is not difficult to use to get high quality work done. To do this, simply switch the drill from normal rotational mode to impact rotation mode.
But it doesn’t matter what type of drill you use, as long as it is important to use specialized attachments. Attachments (crowns) are sold in two configurations: for impact or non-impact drilling.
The classification of nozzles is as follows:
Serrated drill bits with impact function. A concrete wall can be drilled with such crowns with a cutting edge made of separately soldered teeth made of durable alloys. For quick-release drill chucks, these drill bits have SDS tails. Their strength is so high that it is possible to cut metal, but the impact mode contributes to their destruction, creating unacceptable loads. That is why such drills are used to drill a hole between the reinforcement of a reinforced concrete slab or brick walls.
Diamond bit for non-impact drilling. These are more modern attachments that simplify the task several times better than conventional ones. The abrasive edge with cutouts on them is created by diamond sputtering or sputtering of corundum sand. As you know, diamond is distinguished by its unprecedented strength. That is why it can easily cope with the reinforcement of a concrete wall. With such a nozzle you can make a hole at least 1.5 meters deep and more than half a meter in diameter. This type of nozzle is already used by professionals, but nozzles with a diameter of up to 100 mm can easily be used in domestic conditions.
Crowns standard KS. Crowns with diamond crystals embedded on the cutting edge. They can be used for slabs, rocky soils, and monolithic concrete structures made of high-strength grades. They can easily replace toothed carbide crowns.
Based on your conditions, you can safely select the necessary drill bit for the drill and drill a hole. But there are also a number of recommendations for working with a conventional drill, which is not equipped with an impact function.
To do this, you start drilling into the wall, but periodically stop. You need to drive a pointed drill into the concrete surface with your hands and destroy the concrete with metal punches. We take our drill or chisel, other metal devices of the appropriate and required diameter and hit them with a hammer/sledgehammer. Rotate the punch periodically. Then take the drill again.
Please note that when drilling a hole in a concrete wall with a regular drill, you risk breaking the tool. Be sure to give a low-power drill a rest. Drills also tend to heat up, so they need to be cooled with water. In this case, take a break every 10-15 minutes of work, leaving the same amount of time for the instrument to rest.
How to drill a hole in concrete without an impact drill, watch the video:
Concrete is known to be hard and durable material, which is why it is very popular in construction. However, due to these properties, it machining causes certain difficulties. In particular, home craftsmen often face the task of how to punch a hole in concrete?
Methods for drilling concrete
The choice of method for making holes in concrete depends on the tasks:
- If it is necessary to obtain a hole of small diameter, for example, for, then use a hammer drill with a special drill with a carbide tip.
- If you need to get large diameter, for example, to lay pipes, install sockets, etc., they use diamond drilling of holes in concrete 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 or 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.
Instructions for performing this procedure are as follows:
- Before punching a hole in concrete, you need to mark the location that needs to be drilled.
- The tip is then inserted into the chuck of a hammer drill or drill. This sets the depth stop to the desired position.
In the photo - drilling with a hammer drill
- Next, the drill should be rested on the intended point and the tool should be turned on. In this case, you need to place a certain emphasis on the nozzle. Periodically, the drill must be removed from the hole and moistened with water, preventing it from overheating.
- Once the required depth is reached, work is stopped.
It must be said that you can make a hole with a regular drill without impact. However, for this you will need a punch with a hammer. In such a situation, the drill must be periodically removed from the hole and the concrete must be broken with a punch.
Drilling with diamond bits
Often there is a need to make a large diameter hole in concrete, for example, to install a sewer or water pipe. Today there are many companies that provide similar services. However, before you invite specialists, you should find out the cost of punching holes in concrete.
It is quite possible that you will decide to perform this operation yourself. To do this you will need the same hammer drill. The only thing is that you will have to purchase a diamond crown attachment.
Using such a tool, you can make holes with a diameter of 100 mm or even larger. Moreover, a correctly selected bit will allow you to successfully drill even reinforced concrete structures and concrete of any hardness, with any filler.
Pay attention!
Toothed crowns can become jammed when they encounter reinforcement, and their teeth, as a rule, break.
Thanks to this, you can get 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? With this task diamond tool can also handle easily.
In addition, there are some other advantages of this method:
- The ability to obtain a hole of the required size in an absolutely round shape.
- There are no shocks or strong vibrations, making it possible to use this technology in houses that are under repair or reconstruction.
- There is no strong noise.
- Possibility of use when installing air conditioning systems, where sometimes pinpoint precision 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 operating rules, the used nozzle can be restored.
There are specialized companies that provide such services.
The drilling principle 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 a hammer drill, of course, is not suitable for these purposes. In this case, you can drill a hole in the concrete using a professional tool.
Powerful equipment is not held in the hands like a hammer drill. Usually it is fixed to the wall using anchors. Sometimes fixation occurs using the spacer method using a rod, i.e. the lower part rests on the floor, and the upper part rests on the ceiling.
Professional equipment is usually equipped additional functions, such as supplying water to work area, a dust collector that allows you to perform the procedure without dust environment etc.
Advice!
Diamond bits may be needed not only when drilling concrete.
Also effective method is cutting reinforced concrete with diamond wheels and grinding with diamond cups.
Of course, such equipment is very expensive, so 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 yourself. In order for this operation to take place effectively and without special effort, you should use a suitable tool for this and follow the drilling technology.
You can get more information on this topic from the video in this article.
A structure whose surface is as difficult to damage as it is to drill. But if such a need nevertheless arises, then with the help special equipment and following certain rules, this can still be done. And now about everything in more detail.
General provisions
Let's first look at why a concrete wall cannot be drilled using conventional methods. And everything lies in the structure of such a durable material:
As you can see, the action of all components is aimed at increasing the strength qualities of the finished product. Especially critical for conventional drills is crushed stone, which instantly dulls their cutting edges.
And with all the complexity of processing a concrete wall, the need for this can arise very often.
For example, if you need:
- Hang the shelf on the wall or any other furniture interior.
- Finish with plasterboard.
- Implementation electrical wiring, installation of new sockets and switches. In this case, to lay the wire, reinforced concrete is also cut with diamond wheels.
- Plumbing connection.
Execution technology
We have dealt with the need and the difficulties that arise, now we will look at how to properly drill a concrete wall.
Tool selection
First of all, let's decide what to drill into a concrete wall. , of course, do not fit.
You can choose from the following options:
- Drills tipped from Pobedite. But it should be borne in mind that in addition to rotation, a shock function will also be required.
Advice: should not be used cutting tool with a pobedit for drilling iron or wood, as it will crush them.
- Diamond coated drills. Such edges will be able to cut stone even without impact, but their price is much higher.
But the question of how to drill into a concrete wall is not limited to the choice of consumables.
You also need to decide on the tool:
- Regular drill. Only if you don’t have anything more suitable and you only need to make 2-3 holes. And in this case, from time to time you will have to pierce the concrete layer with a steel pin with your own hands.
- Hammer drill. It will cope with a small amount of work even if the diameter of the required holes does not exceed 13 mm. The fact is that the impact in such a device is carried out due to a metal “ratchet”, which wears out quite quickly under intense load.
- Hammer. It can handle large volumes and can even use special nozzles in the form of crowns, which are ideal for drilling nests for sockets. In it, the impact is carried out due to the piston system, which is much more powerful and less likely to fail than the “ratchet” of a drill.
The following general table will help to summarize and give a final answer to the question of what is the best way to drill concrete walls:
Carrying out work
Now let's figure out how to drill a concrete wall. To do this, let's take a hammer drill as a clear winner of impromptu competitions.
The instructions for its operation are as follows:
- We check the shaft shaft for debris. If we find one, we delete it.
- Insert the drill until it clicks. In this case, in some models it may be necessary to pull the slider part of the “nose” of the tool towards you.
- We bring it strictly perpendicularly and begin to drill, lightly pressing on it.
Tip: wet the working part of the drill with water from time to time. This will protect it from overheating and extend its service life.
- During the drilling process, the drill may get stuck. In this case, you should not try to loosen it in order to pull it out, as you may break off the tip. Simply remove the tool from the device, insert a drill of a smaller diameter and try to use it to widen the hole and free the captive product.
- Monitor the equipment while allowing it to cool.
Conclusion
We looked at how to drill through a concrete wall, the process itself is not that complicated. The main thing is to choose the right tools and follow some rules while working. The most practical and rational decision will be the use of a hammer drill with pobedit drills.
