It is easier to drill into a concrete wall. Concrete drill bits for drills: what and how best to drill concrete. Cost of concrete drilling services

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 despite 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 consider how to drill correctly 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. Will cope with a small amount of work even if the diameter 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 generalized 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:

1. We check the shaft shaft for debris. If we find one, we delete it.
2. 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.
3. 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.

1. 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.
2. 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.

The video in this article will provide you with the opportunity to consider Additional information regarding the presented materials. Be careful and you will succeed!

Those who live in houses with concrete partitions are well aware of the situation when it is necessary to hang an object on the wall. At such a moment, a completely reasonable question arises: how to drill concrete? Every House master Anyone who has ever encountered this problem has probably solved it for themselves. But how much effort did it take? First, some people try to test the endurance of a drill coupled with on our own. And without receiving the desired result, they leave the intention of making a hole in the concrete until next time. As a result, the instrument has to be repaired, and the shelves continue to gather dust in their corner. However, there are ways, you just need to find out for yourself and use them correctly in an emergency.

Concrete structures are very durable and difficult to drill. Often you have to rest drills against crushed stone, which is integral part concrete.

It is necessary to make holes in concrete when:

• furniture arrangement;
• facing works;
• additional installation of electrical wiring;
• hanging the air conditioner;
• installation of plumbing fixtures.

How to drill concrete? The issue of drilling concrete can be resolved in 2 ways:

• an impact drill or a hammer drill with a special drill called a Pobedit drill;
• diamond drilling.

It is important to note that using standard drills to make a hole in concrete partition does not seem possible. Therefore, for work, you should prepare drills with soldered plates, which are a high-strength pobedite alloy. They will do an excellent job with both brick and concrete. Do not use them only for working with soft materials, because the one who wins will not cut them, but only crumble them.

What is better to use at home?

At home, when you need to make 2-3 holes on the concrete surface, it is quite suitable simple drill without the “blow” mode. Why, as the drill immerses with the victorious wall material the concrete is tapped with a strong metal pin (punch) corresponding in size to the diameter of the recess.

In particular, a punch is used when the tool begins to “lock” in the wall. Then the steel pin is placed in the recess and struck with a hammer or sledgehammer, trying to crush the overly dense areas and deepen the hole further. At the same time, the rod is turned slightly. After which a regular drill is put back into the process.

The manipulations described above are repeated again and again until the required depth is achieved. This method is not very fast, although it is quite suitable for making a couple of holes.

Another way is in concrete using universal diamond-coated drills. Their work is celebrated high efficiency on metal, concrete and crushed stone. They are attached only to a standard electric drill and other tools without a vibration function.

When working with a drill, extreme caution should be used, otherwise it will instantly fail. The advice from professionals here would be this: to prevent overheating of the drill, it must be periodically moistened with cold water.

What to do when the amount of work is large?

For drilling large quantity To make holes, you will need a hammer drill or a drill with an “impact” mode, as well as drills with hammers at the end.

The impact drill combines rotational motion with reciprocating motion, which allows it to be easily controlled lightweight concrete. For drilling load-bearing partitions made of concrete best assistant a hammer drill will perform, since its main purpose is to punch holes exclusively on concrete surfaces.

There are differences between a drill and a hammer drill:

• holes are not drilled first large diameter(no more than 12 mm);
• Using a hammer drill, larger recesses are drilled.

Drilling of reinforcement found in the thickness of a concrete wall is performed using metal drills.

When making renovations in an apartment or house, the question of drilling the wall always arises. Can be used different instruments depending on the purpose of the hole and the material from which the surface is made.

There are nuances when working with each tool, especially when drilling a wall. How to make the right hole correctly, and what recommendations should you follow?

Drilling holes in the wall correctly: general rules and recommendations for what to drill

In order to correctly drill a wall, you need to take into account the material from which it is made, based on this you need to select a tool.

• When working, hold the tool correctly. For example, a drill should be held straight in your hands and enter the surface in a vertical direction;
• for convenience, use an additional handle;
• Depending on the surface material, select the necessary drills.

The material of the tool used to perform the work must be harder than the surface being drilled.

• concrete, stone, brick wall - use a carbide drill, usually a Pobedit one;
• metal – metal drill;
• tiles, ceramic tiles - special drills for these materials, sometimes they can be replaced with a drill for concrete with Pobedit surfacing;
• Chipboard, wood - for holes smaller than 10-12 mm, a metal drill is suitable; for larger ones, special wood drills are used.

Tools for work

For work they use different tools, the main ones: drill, hammer drill, screwdriver. There are nuances to using each.

Drill

The tool is suitable when you need to make several holes. You can use a regular drill. When plunging a Pobedit drill into the body of the wall, sometimes you need to break the concrete with a punch that matches the diameter of the hole. This is necessary when the drill begins to get stuck in the surface, bumping into areas that are too dense. The process is quite labor-intensive.

For greater efficiency, you can use universal drills that have diamond coating. They are installed only on a conventional drill or on a tool where the vibration function is disabled.

For large-volume work, an impact drill and drills with pobedit tips are used. They are designed for holes up to 12 mm. The drill is suitable for working with metal and concrete.

To prevent the tool from overheating, you need to periodically moisten the drill with cold water.

Hammer

Hammer – universal tool. It can be used to make a hole in a wall made of wood, tiles and concrete.

The tool has several functions - drilling, hammer drilling and impact mode. To make a hole, you need to select the desired drill depending on the surface and carry out the work by selecting the mode.

Screwdriver

A screwdriver is one of the most popular tools for repairs and construction work. With its help you can tighten and unscrew screws, drill wood, metal, chipboard, plywood, tiles, plywood, lightweight concrete.

Which nozzles to choose

A specific nozzle is used for each material:

• concrete, brick, stone - drill with carbide insert or victorious;
• tiles, glass - conical drills with diamond coating;
• metal – spiral drill with a cylindrical cone;
• wood, drywall - for holes of different diameters, drills are used: feather, ballerina, screw, saw bits for wood;
• foam concrete - pobedit drills.

Is it possible to do without a drill and hammer drill?

Make a hole without a drill or hammer drill, but not in a concrete wall. To do this you will need a bolt or a punch.

A bolt is a pipe with teeth at the end. The punch has an end in the form of a chisel or a tetrahedron.

The working end of the tool is applied to the place where the hole will be. On the opposite side of it, you need to strike hard, rotating the tool after each turn.

How to drill without dust: options, the better

Construction work is always accompanied by dust and debris, but using some recommendations and tips, it can be significantly reduced:

• During operation, the hammer drill leaves a slight dust, so that it does not fly around the room. Use it at the same time construction vacuum cleaner. Some brands of tools have a built-in vacuum cleaner, which makes the task easier;
• using a drill, it is best to either make a jig on the end or a bag, or make an envelope under the hole so that the debris falls into it.

How to drill holes in a brick wall: choosing tools and attachments

To make a hole in brick wall A hammer drill with a drill or an impact drill are suitable; the latter is most often used. Its power must be at least 600 watts, minimal amount rpm from 2500 per minute. It is best to use a drill with smooth adjustment power and quick clamping function.

Using the hammer drilling function, the drill becomes identical to a hammer drill. Increases speed and ease of operation. To make a hole in a brick wall you need to use the dynamic impact method. Without this, the drill will not be able to engage inner part bricks

Drills must be victorious. If through drilling is necessary, a drill is used

How to drill a load-bearing wall in a panel house with a hammer drill

In the majority panel houses The walls are made of concrete; to make a hole with a hammer drill, you need to use pobedit drills.

In addition to them, you can use special crowns. They have soldering around the circumference. When using them, you need to disable the impact function of the hammer drill.

Experts use diamond drilling, this requires powerful equipment and skills.

How to properly drill a reinforced concrete pipe with a hammer drill

When using an impact drill for reinforced concrete, you need to use the “perforator” mode and pobedit drills. First, the hole is made smaller, then larger. The drill needs to be cooled periodically.

Important! When working with concrete, you need to avoid hitting the reinforcement, otherwise the drill will break. By using special device you can check where it is located.

How to make a hole in a concrete wall with a drill

It is difficult to drill into a concrete wall with a conventional drill. You need to install Victory drills and select low speeds. IN Right place a dowel is inserted to help the tool pierce the surface. Next, drilling should be alternated with striking the dowel.

The drill must be constantly cooled, otherwise it will burn.

If the drill does not have a speed control, then it will not be possible to make a hole.

How to make a hole in a concrete wall in an apartment with a drill

For a small hole, you can use a punch. Most conveniently, it can be made from a drill, 8 mm in diameter. The end is sharpened sharply. The drill is placed in the desired place, rotated, while simultaneously hitting it with a hammer. Wet the drill periodically to make it work longer.

When working with tools, you must follow safety rules and general recommendations:

How can I repair a large drilled wall?

You can seal unnecessary holes in the wall using a special construction mixture. It provides strength and durability. The composition must be selected depending on the area and type of defect.

Using putty, you can level the surface, including concrete. There are several types of putty:

• cement - used in external and interior decoration, suitable for concrete. Durable and moisture resistant. It dries for a long time and often in a mesh pattern, which requires re-application;
• gypsum - used in dry rooms, is not resistant to water and is afraid of temperature changes. Does not crack when applied, so you can immediately apply a thick layer;
• acrylic – finishing. Needs to be applied thin layer, therefore suitable for small defects.

Neither mixture is used to seal through holes.

Polyurethane foam – universal material. There is one-component (used without preparation) and two-component (when used, applied construction gun or mixer).

When applied, the foam increases in volume and fills the required space. It hardens and gives high-quality density. Deep holes can be sealed.

Suitable for eliminating large defects. It has good adhesion, frost-resistant, strong and durable.

When you decide to make a hole, carefully read the rules and recommendations. Choose a tool, depending on the composition of the surface, and a drill. If you are not confident in your own skills, then entrust the work to specialists.

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 of 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 also damage 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 there is a lot of work to be done, then purchasing a hammer drill 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 hammer drill, 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 drills for concrete. 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 that's it similar designs have durable qualities and are difficult to drill, since most often when working 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, in the process of introducing a pobedit drill into concrete surface Periodically, you need to 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 the punch needs to be turned slightly, and then you can start working again without impact drill.

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 a good drilling effect can be achieved by using a hammer drill. Its advantages in combining functions rotational movement with reciprocating motion. 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 is a durable and reliable material. Many, if not most, buildings are constructed from monolithic or precast concrete. As a rule, the holes for the gasket engineering communications, pipelines, as well as recesses for installing electrical and low-current fittings are provided during the molding process concrete structures. But their location often does not suit the owner of the premises, and holes have to be drilled at new points. Let's try to figure out how best to do this.

Choosing a tool

Initially, you should determine which tool is better and more efficient to drill into a concrete wall. In a global sense, the choice is small - an impact drill or a hammer drill. But there can be many nuances, since power tools come in different power and functionality, and there are also many attachments for them. Therefore, you should define goals and objectives, and then decide which tool may be needed. So:

• To screw into the wall small screw You don't need a lot of effort to create a painting. In this case, you can drill into a concrete wall with a conventional drill equipped with a drill bit with a Pobedit tip.
• When a small amount of work is expected, and the diameter of the holes to be punched does not exceed 12 mm, then an impact drill should be chosen.
• A hammer drill is used to drill holes of large diameters, as well as any size, in concrete, but in significant quantities.

The advantage of a rotary hammer over a drill, even with an impact function, is not only greater power and endurance. This tool uses not only drills as a working tip various sizes and quality, but also drill bits. This is the main device that can be used to drill a hole in concrete for a pipe.

Professional installers, when punching large-diameter holes in concrete, use special units, which include:

• Electrical engine high power;
• durable bracket with guide structure;
• drilling drive;
• drill bits with a diamond working area.

Such equipment allows you to make a hole or recess with a diameter of up to 40 cm in a concrete wall.

What will win more effectively or a diamond?

When you need to make only a few holes for a construction dowel, and there is no hammer drill at hand, then use a regular drill with Pobedit drill is quite real. Also this option fits better only if the working surface is concrete, but made of cellular material. The hammer drill will destroy it. But when working with a Pobedit drill, remember that it is short-lived and requires periodic replacement. In addition, such a drill can “drill” into concrete. Then he needs to be helped manually with a punch and a hammer.

Drilling into a concrete wall with an impact drill equipped with a diamond-coated drill bit is much more effective. Diamond drills They cost a little more than Pobedit ones, but they also last longer. And further important point. Unlike Pobedit, a diamond drill punches holes not only in concrete and stone, but also in ceramic tiles, porcelain tiles and metal. When working with a diamond tool, it is not scary to stumble upon a reinforcement frame in the wall. It is better to purchase drills as a set, which includes drills various diameters. This is more profitable than buying them individually.

When a hole with a diameter of 35 to 120 mm is drilled in a wall, diamond bits are used as a cutting device. They are steel rings with carbide tipped work area, coated with diamond coating. For domestic purposes, crowns with a diameter of 6.8 cm are usually used; holes of this exact diameter are needed for installation electrical outlets and switches.

How to drill concrete correctly

Punching holes, like any other, requires preparation. In addition to tools and accessories, you should stock up on water to cool drills and bits. Before drilling into concrete with a drill or hammer drill, inspect the wall for:

• hidden heating pipelines, water supply;
• electrical wires, cables.

The search is carried out with a metal detector; identified communications are marked along their entire length. Electrical wiring according to work surface It's better to turn it off. Further:

• Mark the locations of future passages. If large diameter holes are expected, then the designation is made along the contour and axes.
• The depth of the hole for the construction dowel is 8-10mm greater than its length.
• To obtain a more accurate result, you need to drill concrete correctly. This means that the start of drilling should be done at low engine speeds.
• After a small depression is created, the speed is increased and the tool is switched to impact mode.
• If possible, provide a water supply to the drilling site. If this option is not available, periodically moisten the drill with water in a previously prepared container.
• If drilling with a drill is carried out in one position of the tool, then when drilling with a crown, the hammer drill must be slightly rocked. This way, waste will be easily removed from the resulting hole and the crown will not jam.

The most difficult obstacle that has to be overcome when drilling a concrete wall is the reinforcement cage. Small diameter steel bars diamond crown cuts on its own. When drilling with an impact drill, metal drills should be used to remove the reinforcement.

Wear safety glasses and a respirator. It is convenient to collect the resulting dust with a vacuum cleaner. Every 15 minutes of drilling, give the tool a break for approximately the same period of time. To continue working, moisten the drill with water.
