How to drill a concrete wall with a conventional drill: expert advice. How to drill a concrete wall correctly: technology. Choosing a tool for work Which drill to drill a hole in concrete

01.06.2020

In modern buildings, as a rule, the walls and ceilings are concrete. Sooner or later, it may be necessary, for example, to hang a lamp shelf or sheathe the walls with drywall during repairs, then the problem arises of how to drill a concrete wall with a drill.

Difficulty in drilling can arise due to a number of reasons. Firstly, the structure of concrete panels is heterogeneous and includes iron reinforcement, cement-sand mortars and crushed stone, which leads to difficulty drilling. 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;

perforator.

A perforator will do a better job of this job, since its function is precisely the punching of concrete or stone surfaces. Using this tool, you can make large holes, but even the highest quality impact drill is not capable of more than 12 cm.

But when you need to drill foam concrete walls, it is the drill that will be optimal, since the puncher will simply crumble the surface.
When working with concrete walls, it is absolutely impossible to use a hammerless drill, because it will be pointless, and besides, you can ruin the tool.

When there are only a few holes to be made and there is no puncher, you should not buy it because of this, you can get by with a drill. If you have a lot of work to do, then buying a puncher is inevitable.

In the case when it is still necessary to work with a drill, it is important not to forget that it is necessary to use a concrete drill with a carbide-coated tip.

Diamond drills and other accessories

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 consider that such devices are expensive, and therefore for home use they are not worth buying.

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 soldering of hard alloy 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 sockets and switches have it. If you are drilling with a crown, then it is important not to forget to turn off the hammer blow function. With this device, holes are drilled, the depth of which is a maximum of 15 cm. If a greater depth is required, it is recommended to use an extension nozzle.

Similar crowns 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 with tiles, then it makes no sense to replace the nozzle, since it is good, and concrete surfaces. But we must not forget that such devices can be used for drills with a power above 1000 watts.

Most often, drills are used to work with a perforator, the cross section of which has limits from 4 to 80 mm. Many are faced with the problem of choosing the correct diameter of the drill. But the most reasonable thing when buying a perforating device is to purchase a set of drills for concrete. But a high-quality kit also costs a lot of money, in connection with this, it is necessary to select the same 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 hard to drill, since most often during work you can stumble upon crushed stone, which is part of the concrete composition from which wall and ceiling structures are made. Holes in concrete slabs during construction are made quite often:

during finishing work;

when installing built-in furniture;

when installing air conditioners;

when installing electrical wiring;

when installing plumbing fixtures.

During 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 a concrete surface, it is periodically necessary to crush the concrete with a metal punch, which must correspond to the cross section of the hole. It is used when, when drilling, an electric drill begins to get stuck in concrete. Then the punch is placed in the hole and beaten on it, using a hammer or sledgehammer, which helps to crush the compacted places and penetrate deeper. But at the same time, the punch needs to be slightly turned, and then you can again start working with a non-impact drill.

These manipulations should be continued until the holes reach the desired depth. This method is very long, but suitable for several holes.

Of course, you can also use universal diamond-tipped drills. They will perfectly cope with metal, crushed stone, and also with concrete structures. But it is important to consider that they are only suitable for an ordinary drill or a device with the vibration mode turned off. When using diamond drills in work, it should be remembered that they require cooling during operation.

But a good drilling effect can be achieved by using a perforator drill. Its advantages are in combining the functions of rotary motion 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 laborious.

Sooner or later, most people living in houses with concrete walls need to hang a cabinet, a lamp, a shelf or a picture. At this point, the burning question of how to drill through a concrete wall comes up. It's no secret that every home master has encountered this problem at least once in his life, but not everyone knows how to solve it. Many courageously torture the drill and own forces, but, not achieving the desired result, they give up everything until the next attempt to make a hole in the wall. But the drill eventually breaks, and the shelves remain standing somewhere in the corner of the room or gathering dust in the pantry. But there are still options - you just need to know them and be able to use them.

Concrete structures are strong enough and difficult to drill. In addition, quite often drills stumble upon crushed stone, which is part of concrete mix from which wall and ceiling plates are molded.

Holes in concrete have to be made quite often, especially in the process:

finishing works;
furniture installations;
air conditioner hangers;
additional electrical wiring device;
plumbing installation.

Solve the problem of holes in concrete wall can be done in two ways:

impact drill, and preferably a puncher, with a drill bit;
diamond drilling.

It is worth noting that it will not work to make a hole in a concrete wall with ordinary drills, therefore, before starting work, it is necessary to purchase drills with specially soldered plates made of high-strength pobedit alloy, which do an excellent job with concrete and brick. But for soft materials it is not recommended to use them, since Pobedite drills do not cut them, but crumble them.

What will help the home master?

In domestic conditions, when it is necessary to make 2-3 holes in concrete, you can get by conventional drill, without impact function. To do this, it is necessary, as the drill drill is immersed into the body of the wall, from time to time to break the concrete with a strong metal pin (punch) that matches in size with the diameter of the hole. It is used in the case when the drill begins to "stop" in the wall. At this moment, a steel punch is inserted into the hole and they begin to hit it with a hammer or sledgehammer, trying to crush too dense areas and punch the hole deeper. In this case, the pin is rotated a little. Then the hammerless drill can again come into operation.

All the above steps are repeated one after another until the hole is enlarged to the required depth. This method is quite laborious and tedious, but for a couple of holes it is quite acceptable.

Alternatively, when drilling a hole in concrete, you can use universal diamond-coated drill bits. They are highly effective when working with metal, crushed stone and concrete. They can only be installed on a conventional electric drill, or on a tool with the vibration function turned off.

It is necessary to work with a drill very carefully, otherwise it will fail too quickly. The advice that professionals give is to avoid overheating the drill, it should be wetted with cold water from time to time.

How to decide on a tool?

For more work, you need a hammer drill or drill with a percussion function, and drills with victorious tips. An impact drill combines rotational with reciprocating motion, which helps it cope well with lightweight concrete, and there is a simple answer to the question of how to drill a concrete wall, which is a load-bearing one - a hammer drill will be the best assistant, the main purpose of which is punching concrete fences. There is one more difference:

impact drill is designed for drilling holes no more than 12 mm in diameter;
The hammer drill is capable of drilling large holes.

Drilling the reinforcement caught in the body of a concrete wall should be drilled for metal.

What are big holes drilled with?

Professionals who are constantly faced with the problem of drilling holes in concrete use special equipment, which includes:

powerful electric motor;
drilling drive;
diamond drill bits of different diameters;
guide post fixed on the base.

Diamond drilling allows you to make holes of large diameter - up to 40 cm. The process is fast enough, efficient, without unnecessary dust and noise. Water is automatically supplied to the drilling site, which simultaneously cools the diamond bit and washes away dust.

The master has to make holes in the wall both in the case of capital construction and in solving everyday problems. Much in this matter depends on what material the base plane is made of. The diameter of the future hole also plays a role. Therefore, the material of manufacture of the drill plays an important role - it must be selected correctly. The difference can be significant - any professional will confirm this.

If it’s quite simple, then: a drill for holes in a brick will definitely not cope with concrete - it will burn out in the process. How holes are made in different materials - this needs to be discussed in detail. Let's take a look at the different tools and guidance on when to use which one.

Device for deepening in the wall surface - which is better

How to drill a hole in a wall - this question often arises before a beginner. Today it is not difficult to cope with such a task. If a person has at least minimal experience and uses modern electrical tools in his work, he will definitely cope.

So that after all the work the room remains clean, it is worth using a conductor - thanks to it, you can drill with a minimum amount of dust and pollution.

A puncher is perfect for creating holes in the wall, if, for example, (or for other purposes) - professionals advise using it. Such a technique can easily cope even with high-strength materials; nothing better than a puncher for holes in the wall has yet been invented. But quality tool is expensive for home use almost never buy it. Another option for making holes in the wall is an electric drill, which has a punch effect.

It is the drill that is most often used for cutting holes in the walls. Such a tool is available in almost every family. Some advice from experts will help to significantly expand the scope of use of a conventional drill - there is nothing complicated here.

When choosing a drill, it is important to read its technical description carefully. The recommended power of the appliance is at least 600 W, suitable revolutions are no more than 2500 per minute (it is desirable that there is a function for their adjustment).

And now in detail:

The presence of a reverse is mandatory. It is this function that allows you to change the rotation of the drill - counterclockwise and clockwise. A model with a keyless chuck is a great choice, because then you don’t have to waste time looking for a key, through which the drills in the device change;
The impact function of the device is also welcome. It is needed so that the device can easily make holes on any wall surface. It is easy and pleasant to work with such a drill. The bottom line is that certain materials (concrete, cement, bricks and not only) are quickly destroyed by dynamic influences (we are talking about impacts). That is, when a drill does not have this function, it can take a lot of time to drill a hole in the wall. The drill clings to the composition, heats up quickly, but this is of little use. Impact drilling will radically change the approach to business - you get something in the style of chiselling, speed is guaranteed.

Choosing the right drill - how not to make a mistake

Perhaps everyone has seen with their own eyes an impressive range of drills in hardware stores and other retail outlets. It's time to talk about which drill is better to use in certain situations.

Foam concrete, plasterboard, wooden surface can be easily drilled with the simplest drill - there is nothing complicated in this process.

At work with concrete, stone, brick everything is different: here the drill is specially chosen, carbide products are the preferred solution. Unlike a simple one, such a drill is equipped with cutting blades - welded elements are visible, just look at the product.

Every home should have at least a couple of these drills. Common sizes are 6-8 mm. There will always be a use for these products, you can not worry about this. With their help, at any time you can drill a hole in the wall up to 20 cm deep.

Bur - great choice to make a big hole. These products are able to cope even with a dense surface. A meter deep is not the limit for them. But a drill is no longer suitable for such work - you need to choose a hammer drill and work with it.

Details about the drill and its use:

Boers usually have tails that are 15 mm or more in diameter. There are grooves - they are designed for fastening. However, if the drill is working in hammer mode, they are clamped well in the chuck. On the tail of the drill are its characteristics;
If the task is to drill a solid surface, the process is usually divided into a number of stages - then drilling is carried out as quickly and safely as possible;
First, a drill is selected: the recommended length is up to 200 mm - it will easily reach a depth of 150 mm;
Then choose a long drill, designed already for 350 mm;
Drilling is completed with a product whose length is 500 mm. You can't do without a high power drill. But, as mentioned above, such a technique is not designed for heavy loads - except perhaps in certain situations;
When buying a puncher is not possible for some reason, it makes sense to rent it for a couple of hours - today there are services that provide such a service.

If you need to punch a hole in the wall with a diameter of 150 mm or more, a drill will be the best tool. They are distinguished by reliable fastening in the cartridge, have an impressive length.

Safe drilling of walls with your own hands

You can get a hole in the wall yourself. It is important to do the job safely, but at the same time efficiently and quickly. For different wall materials there is own instruction for the performance of work - these rules must be observed.

The master before drilling should carefully examine the surface of the wall. In the place of the future deepening there should not be cables - electrical or any other. If you rush to this stage– You can seriously damage the wiring. Moreover, even the master's own health may suffer due to such carelessness. Fortunately, it is possible to bypass cables while drilling.

How not to get caught in the wire when drilling walls

On the walls are usually located sockets, switches. They must be examined carefully. It is from such nodes that network wires diverge vertically. They go to the junction box.

If this is the case, then this is an ideal situation, which is rare. As a rule, electricians do not follow the recommendations in all cases and go straight ahead - to save the cable. That is, diagonal wires in houses and apartments are located everywhere.

Detailed guide:

Usually, in order to check whether there is a cable on the wall section or not, devices are used. They are not expensive and locate the wiring accurately;
If such a device is not at hand, it is worth understanding that the wire is usually placed at a depth of up to 1 cm in the wall surface. To find out whether it is there or not, you can carefully make a small hole using some blunt tool. If there is no cable, you can safely drill. Experts say that the recess can be made up to 2 cm - to make sure there is no cable;
The drill does not need to be pressed too hard against the wall. Every few millimeters, the master must inspect the hole - is there any wiring there. The wire electrical network can be found special device- it is presented in almost all specialized stores. When buying such a product, it is worth clarifying whether it is of high quality. It is worth choosing the best - after all, the health of the master depends on his testimony. Such an apparatus will show the places where reinforcement lies in concrete surfaces - this is also important when drilling;
Copper electric wires searched faster - if they are no further than 1 cm in the wall. And the search for aluminum wiring can only be done with a device with a metal detector function. In the process of searching, you need to look at the indicator constantly - it is made in the form of an LED light bulb. However, he also emits a signal, so you need to watch out - the "assistant" will definitely inform you if he finds something;
If the metal detector mode is on and something is found, the diode will start to glow, the master will hear a continuous sound. In any modern device there is also a sensitivity regulator. The finder feeds on a standard "Krona".

Any builder who installs tension and suspension structures on the ceiling surface cannot do without such a unit. Systems on the ceiling are most often fastened with self-tapping screws - this is where all the electrical cables run. In a word, you can’t do without insurance - you need to use the device.

Drilling holes in brick or concrete surfaces

The current topic is how to make a hole in a brick or concrete surface. For a brick, a victorious drill is enough.

A conductor is attached to the place where the work will be carried out. A slot is being drilled - in the process, the revolutions of the power tool should not be high: the drill should not overheat.

If the surface of the ceiling or walls is made of high-strength cement, drilling may be difficult. Usually 400 brand material is used here - if so, then there will be no problems during operation. And if the building was erected a long time ago, the concrete there is very strong and it will be difficult to drill.

Besides:

Today, manufacturers are investing iron fittings in wall blocks and panels - to improve quality. These are rods, the thickness of which usually does not exceed 2 cm. Crushed stone can also be found here. You can't take all this with a Pobedite drill;
But there is a way out. If the drill hit the rebar, you need to put an ordinary drill. If in right moment it was not there, the place for deepening is moved slightly down or up diagonally;
Drill blows can crush crushed granite in the wall. During this work, the tool often jams. To simplify your task, the mechanism should be rotated 4 turns;
When the obstacle is passed, the master continues drilling with a drill bit. The drill and the puncher will cope with the problem of such a plan instantly, the worker will successfully get what he wants.

Holes in tiles

What if you need to drill a tile? For this work, a drill with welded protrusions is chosen - outwardly they resemble teeth. It is these elements that are commonly called a crown for drilling tiles.

But if you need to get a small hole, you should not use a crown. Then a mark is made in place. Further work is carried out as follows:

To make a mark on the tile, a core is used. When such a tool is not available, you can take a simple self-tapping screw or a thick nail with a sharp tip. The glaze from the tile is carefully removed where the hole should be. Small revolutions are set on the tool - the same as when working with bricks;
Once the glaze is removed, a hole is made with a small drill;
Then it is expanded to the required diameter - a thicker drill will help with this.

Large recess in the wall

When the installation is done ventilation systems, wide recesses are usually made in the wall - 20 mm or more. A meter is also often placed in the wall (the one on which the electricity indicators appear) - in this situation, you will have to make a niche at all. A carbide drill will help solve the problem in a private house.

You have to act like this:

On the wall, mark a place for deepening - with a simple pencil. From the outside, holes are drilled on the wall; drills with a diameter of at least 5 mm are selected for work. A distance of 1.5 cm is maintained between the holes;
To go deeper into the surface by 20 cm, it is necessary to make about 30 revolutions with a drill. Only after that, materials are removed from the wall with a hammer and a chisel - in this case, a niche of the required dimensions will be formed. If drills of a smaller diameter are used, the edges will come out neat. But you have to make more holes to achieve the desired result.

A common situation: the wall is made of solid material, so it is difficult to get a through recess. In this case, the work is carried out in several stages..

Namely:

If a surface can be drilled on both sides, it is first done on one side, after which a through full recess is already performed. The steps taken are repeated until the result is satisfactory;
When it is not possible to drill the surface of the wall from one side and the other, the processes are done in turn, the work is not done at once, but in several steps. From the mark made earlier, another line is drawn. As soon as the unnecessary material is removed, you can deepen the drill into the niche - you do not need to touch the edges on the wall in the process. A long drill at the beginning of work will greatly facilitate the work.

In fact, drilling a hole in the wall is not as difficult as it seems - including, get a precise, neat recess:

A sheet of sandpaper is glued with glue or tape on the side of the conductor. The size of the element depends on the area where the hole is located. Due to such a simple manipulation, the adhesion of the device and the wall surface will increase, the master will accurately make the perfect hole where necessary. Stationary limiters are also used frequently. The cost of the product is quite moderate, in retail trade everyone will be able to find it;
Sometimes a hole needs to be drilled under the dowel. As you know, they can have different diameters, but most often - up to 10 mm. It all depends on what you plan to hang, the weight of the product also plays a role. The density of the wall material must be taken into account;
To get a universal conductor, several holes of the required size are made in it with a simple drill - so that the device can be hung without problems;
Often a plate is attached to the conductor. Thanks to this, the shelf reliably protects the wall surface finish from debris and possible dust. Such a device is also used for drilling holes;
Places of the required sizes are measured on the conductor - from the shelf at the required height. Next, holes are drilled. To get the optimal recess, the shelf is laid on the floor - the slots will come out exactly in size, at the required height. When performing installation, it is worth acting in stages, following the rules. On the floor surface the plinth will lie correctly - there is no doubt about it;
Sometimes you need to hang one or another on the wall decorative element- a frame for a photo, a picture or something like that. It can not be done without an auxiliary conductor. The bottom line is that the holes should be located at a clear distance between them. It is worth considering your wishes and making sure that the work is done in the same style as the entire room.
In order to make a conductor with your own hands, which will help you drill holes as correctly as possible, a metal sheet or plywood is selected. Marking is performed on this element, then the required number of recesses are made with a regular drill.

It is worth considering options when parts need to be mounted on several screws, and not on one:

On the wall, the first hole is drilled, the second is made with the same size as the self-tapping screw. The conductor will help to get the exact recess. After the dowel is hammered into the hole;
The conductor can be screwed to the wall surface with a self-tapping screw and a dowel. Alignment is carried out with a water level - this method will help to get even recesses and they will all be located on the same horizontal line, which is required;
With help simple conductor(which you can do yourself) you can get recesses with a drill - they will be at the distance from each other that is planned;
This technology will help the master to make holes even at large intervals. First, holes are drilled for this, as mentioned above. Then the conductor is screwed on with screws on both sides. The drill makes other recesses and the result is perfect.

If you plan to pass the cable through a hole in the wall, it should be made more by 20%, because it should not be pinched. The main rule for cable in the wall is freedom.

Results

This is what the answer to the question looks like - how to drill a large diameter hole in the wall. Everyone will cope - the main thing is to act without haste, to apply the markup correctly.

Video on the topic will help to realize the plan:

Limiters will help to drill the wall to the desired depth, with the required diameter. Working with brick is not as difficult as working with concrete - but accuracy in the process does not hurt, as in any other business - it is important not to forget about it.

Many people live in houses with, and when it becomes necessary to make a hole in them, they encounter serious difficulties.

Do not despair and be upset if you did not immediately manage to hang a shelf, lamp or cabinet, read our recommendations and everything will work out.

There are several options with which you can drill a concrete wall yourself.

Concrete structures are highly durable, so drilling them yourself is quite difficult.

This is due to the fact that crushed stone is used to create concrete products, and when you hit it during drilling, the process becomes very difficult.

The need to drill a concrete wall arises quite often, it is necessary for the installation of shelves, cabinets, air conditioning, fixing a lamp, at or during the fastening of beacons.

There are several ways to solve this problem:

using a hammer drill or a powerful impact drill;
conventional electric drill or screwdriver;
diamond drilling.

To carry out this work, an ordinary drill is not suitable; it is necessary to purchase tools soldered with a pobedit alloy.

It should be remembered that for walls made of relatively soft materials, it is impossible to use pobedit drills, since the holes will turn out to be uneven and the wall will collapse. It is also impossible to work with metal with such a tool.

To create holes of large diameter or, diamond-coated ring drills are used. To use such a tool, it is necessary to use special installations; they allow you to make holes with a diameter of up to 250 mm.

Since the cost of such equipment is high, it is easier to hire specialists or you can rent it.

What is the best drilling

As already mentioned, there are several ways to drill a concrete wall, we will consider each of them in more detail.

perforator

When using a hammer drill or impact drill, they must be switched to impact mode, a working tool with a victorious tip is inserted and it must be directed perpendicular to the wall surface.

If drilling holes takes a long time, then drill needs to be moistened periodically so that it doesn't overheat.

Once you have drilled to the required depth, it is necessary to pull the working tool back without turning off the perforator. To clean the finished hole from dust, it is necessary to deepen and pull out the drill several times.

Standard drill or screwdriver

If you do not have the tools described above, then you can do this work with a conventional electric drill or a powerful screwdriver.

To perform drilling, you will need more time than using a hammer drill, but you can do everything yourself.

In this case, in addition to a drill and a drill, you will also need a punch. First, a small indentation is made at the drilling site with a punch and a hammer.

After that, insert a working tool into it and start drilling. If the drill has stopped, break the hard sections again with a punch and continue to work.

Although a conventional electric drill or screwdriver is not suitable for working with concrete, but if you do not have a hammer drill, then you can make several small holes with these tools, but you must use a lance-shaped drill with a carbide tip, it is usually used for tiles.

Diamond drilling

This is the most effective method, with which you can simply and quickly make a hole of the required diameter in a concrete wall.

To perform these works, you will need special equipment, consisting of the following elements:

electric motor;
a stand that is securely fixed to the base;
drill bit.

During operation, it is not necessary to cool the drill, as water is supplied to it, which not only cools the tool, but also prevents dust from forming.

If specialists work, then together with the specified equipment they use a vacuum cleaner, with which they remove dust and water.

As the price of such equipment is very high then buy it for domestic use impractical. If necessary, make a hole of a large diameter, for this you can always invite specialists.

In order for you to be able to properly drill a concrete wall, you must have necessary equipment, perform all work carefully and adhere to the following recommendations:

without a hammer drill, work can be done with an impact drill or drilled with a screwdriver;
do not buy cheap drills, as their winning tip disappears very quickly and they fail;
instead of a punch, you can use a victorious tool, with one you will break the rubble, and with the second, inserted into a conventional electric drill, drill;
to work with concrete, the perforator must have an SDS-plus cartridge;
consider the placement of the reinforcement to determine where it is located, you can use a metal detector if the reinforcement is exposed, it is necessary to prevent rust;
to work with concrete, you can use universal diamond-coated drills, but you need to insert them only into a regular drill, or you need to turn off the impact mode.

Conclusion

During the performance of these works, it is necessary to adhere to the developed technologies and safety rules, then you can not only make a hole yourself without involving expensive specialists, but also avoid injuries.

Drilling holes in the wall should be done as in capital construction as well as in everyday life. And in this matter, everything depends on the material of the base plane and the diameter of the hole. Therefore, it is necessary to choose the right material for the manufacture of the drill. After all, there is a significant difference here.

A drill for making a hole in a brick will not withstand concrete and will simply burn out. Today we will look at how holes are made in different materials. Also on the video in this article and the photo you can find out the options for the tool and choose the one you need.

What device is better to make recesses in the wall surface

It is quite easy to carry out installation by drilling recesses in our time. If a person is trained and correctly uses modern electric tools, then there will be no difficulties. To keep your home clean after work, use a jig that allows you to drill with a minimum of dirt and dust.

It is easiest to make a hole in the wall with a perforator, which is what professionals advise to use. He will cope with the most durable materials in the wall in the best way and nothing better has yet been invented. But such a power tool is expensive and not everyone can buy it for home use. An electric drill with a blow effect will help to make holes in the wall.

Cutting holes in the walls in most cases is done with a drill. This tool is in almost every family, and experts give their recommendations, they will expand the scope of the drill.

Attention: When choosing a drill, carefully read the technical descriptions. The power of the electrical appliance must be at least 600 W, and the revolutions can be no more than 2500 per minute, and this is in the mode of their regulation.

So:

Reverse is required, which changes the rotation of the drill clockwise and counterclockwise. Choose a model with a keyless chuck, only then you will not spend too much time looking for a key to replace the drill.

Do not forget that the device must have a shock function. It will help to cope with any complexity of the wall surface, and drilling holes will be quite easy and simple. And that's all, because materials such as bricks, cement or concrete are quickly destroyed by dynamic actions, namely, by impacts. If the electric drill is not equipped with such an impact function, then the simplest drilling process will take a long time. The drill will cling to the composition located in the wall and at the same time get very hot, but this will be of little use. Here is such a feature as impact drilling is generally different. This is something like chiselling.

How to choose the right drill

Probably everyone saw a huge assortment different types drills in shops and markets. Now we will figure out which one is best to use. It is not difficult to drill a wooden, plasterboard or foam concrete surface of the walls with the most ordinary drill.

Now, if the material is brick, stone or concrete, then it is better to choose a drill made of hard alloys. Unlike the previous one, it has victorious cutting inserts. Welded elements are visible on the edge.

If your house has at least a couple of such drills with sizes from 6 mm. up to 8 mm is already fine, be sure they will still be needed. With their help, you can make a hole up to 20 cm deep.

When you need to make a large hole, you need to purchase a drill. They drill dense surfaces almost a meter deep, but only with a hammer drill, an ordinary drill will not help here.

So:

The drills have tails with a diameter of 15 mm. and more, there are grooves that serve for fastening. But if the drill works as a puncher, then they are clamped quite well in the cartridge. The characteristic of the drill is on the tail itself.
If you need to drill a solid surface, this process is divided into several stages, drilling will be safe and fast.
First, a drill up to 20 cm long is selected. Designed to a depth of almost 15 cm.
Next, use a long drill designed for 35 cm.
Drilling ends with a 50 cm drill. This requires a powerful drill, but notice earlier, we mentioned that it is not designed for heavy loads, except for individual cases.
If buying a rotary hammer is not an option, rent one for a few hours.
