Is it possible to drill concrete with a screwdriver. Polishing

How to drill a concrete wall with a screwdriver?

Before drilling, you need to fix the screwdriver in drilling mode. There is a tool arrow, indicating the drill icon. Screwdriver must be kept a little perpendicular to the axis of drilling. In order for the drill to deepen into the material, you should press the tool. But slightly, otherwise you can break a drill and damage your hands. In the process, the pressure should be loosened and removed from the hole to remove metal crumbs and dust. This information is useful to know how to drill a wall with a screwdriver.

Is it possible to drill concrete with a screwdriver?

Greetings! This article will talk about whether it is possible to drill concrete with a screwdriver. It happens that it is necessary to make a hole or recess in concrete, and besides a screwdriver, there is nothing at hand. We’ll have to think about what to do with it. There are of course shock screwdrivers, but even they will not cope with concrete. The maximum is a brick.

Of course, I still recommend getting a perforator for such cases. Even the cheapest. You will make holes then in seconds. But if you need to do work right here and now, then you can try the following method. True, for him, in addition to a screwdriver and drill, two more things will be required. A punch and a hammer.

The drill can be used ordinary for metal. Though after this work it will instantly be dull and then it will have to be hidden to drill the metal. If the screwdriver is struck, then you can apply a drill on a brick with a carbide attack at the end.

How to drill?

• First, put the punch to the right place and knock on it with a hammer until a certain recess appears.
• Then take a screwdriver and drill a drill. So you delete what the punch was overwhelmed, and you can also advance a little more, as the drill can drill the solution. But it cannot cope with a large filler, such as stone or crushed stone, so it can only be drilled before it rests on them.
• Когда сверло упирается в камень или щебень, то снова берем пробойник и колотим по нему молотком.
• Repeat the actions until the desired result is obtained.

Work is quite difficult and requiring a lot of effort. But nevertheless leads to the desired result. That is, the work that the punch does on the go, in this case, you will have to make a punch manually.

If you replace the reinforcement during work, then change the place of drilling. Of course, you can try to drill the reinforcement with a drill for metal, but this will be an even more laborious process, so it is easier to change the place of drilling.

Drilling with a diamond crown

In fairness, it is worth writing about such a method as drilling concrete with a diamond crown.

There are special drills for diamond drilling, which are quite massive devices that are drilled with diamond crowns. And theoretically, such a crown can be adapted to a screwdriver. In these crowns, the seat is a small rod with a 1/2 inch thread. And if you have a 13 mm cartridge on your screwdriver, and not 10, then you can squeeze such a crown right behind this rod.

If the cartridge is 10 mm, then you need to come up with any adapter.

However, this story has one fat “but!”, Which completely crosses out all these plans. And this is “but!”. The price of a crown that is comparable with the price of a new punch, and often even more expensive. Therefore, this method can be immediately thrown aside.

Therefore, again, I recommend getting a perforator. For example, on the site all.Tools.Ru the cheapest punch can be bought for very funny money. You can make sure that by clicking here.

Well, on this article you can finish. Thank you for your attention!

Thus, the concrete can be drilled with a screwdriver, but it will be difficult to do it. In fact, the main work will be completed by the punch. During the Soviet Union, people in concrete actually made all the holes precisely by the punrate and did without screwdrivers or drills at all. Scurop reverlet in this case only a few simplifies work.

Therefore, again, I recommend getting a perforator. For example, on the site all.Tools.Ru the cheapest punch can be bought for very funny money. You can make sure that by clicking here.

The better to drill

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

Perforator

When using a perforator or shock drill, they must be switched to the stress mode, a working tool with a winning tip is inserted and it should be directed perpendicular to the surface of the wall.

If the holes are drunk for a long time, thenperiodically you need to moisten the drill, so that it does not overheat much. After you drilled to the required depth, 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.

Ordinary drill or screwdriver

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

To perform drilling, you will need more time than when using a punch, but you can do everything with your own hands.

In this case, except for the drill and drill, You will also need a punch. At first, at the place of drilling with the help of a bark and hammer, a small depression is made.

After that they insert a working tool into it and begin to drill. If the drill stops, the hard areas are broken again and continue to work.

Diamond drilling

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

To carry out these work, special equipment will be required, which consists of such elements:

During operation, it is not necessary to cool the drill, so water is supplied to it, which not only cools the tool, but also does not allow dust to form.

If experts work, then together with these equipment they use a vacuum cleaner with which dust and water are removed.

As The price of such equipment is very large, then buying it for domestic use is inappropriate. If necessary, make a hole of large diameter, for this you can always invite specialists.

How to use a screwdriver correctly?

Many masters prefer to use a screwdriver instead of a screwdriver. It saves time and do work quickly and efficiently. Let’s get acquainted with the principles of work and the device of this tool, learn the spheres of its application and operating rules, and also give several useful tips.

Device and principle of operation

Scurgets can be used in various fields of activity and for various actions, for example, in everyday life, during the construction, assembly and disassembly of furniture, in different workshops and where many mounts are used. They can be drilled, thread, twist and unscrew the fasteners. Let’s get acquainted with the device and the principle of operation of such a mechanism.

All screwdrivers are divided into three types:

• Working from a conventional network and called network;
• Operating from a charged battery and borrowing battery;
• Working both from the network and from the battery. The combined version.

Drillmaster 4 Branch

All screwdrivers are very similar both in the external and internal structure. They consist of elements such as:

• Frame;
• Cartridge;
• Power button;
• Rotation switch;
• Speed regulator;
• Blocking button of turning on;
• Tightening power regulator.

In some models there is additional illumination, and in some there is no one or another element. So, the models operating from the network have a power cord, while the batteries have a charge drive.

The power tool case consists of two parts and can be made of plastic or alloy of various metals, but this is much less common.

The principle of operation of all screwdrivers is similar to each other. The electric motor is brought into rotational movement using the consumed electricity, which transfers an effort using a gearbox and a shaft from the motor to the existing nozzle installed in the cartridge, and the nozzle already performs the process of drilling, screwing or twisting fasteners. In network screwdrivers, the engine uses an alternating voltage of the network of 200 V, and in the battery. A constant voltage from 3.5 V to 36 V.

Replacing the nozzle is also quite easy and simple. At the same time, a screwdriver may have a fast.Packed cartridge or turnkey.

Change of nozzle with a fast.Packed cartridge:

• First you need to choose a drill for the works that you plan to do, or the bat, given the size of the hat, the type of slot;
• The cartridge is promoted counterclockwise;
• Install the selected nozzle;
• Rotating the cartridge sleeve in the direction of movement of the clockwise, there is a clip of nozzles.

Change of nozzle with a turnkey cartridge:

• Take the key and insert it into a special recess;
• Spin the cartridge;
• Insert a new nozzle;
• Rotate the key in the direction of movement of the clockwise, fixing the nozzle.

How to prepare for work?

The first thing you will need to do in order to get to work is to remove the screwdriver from the case or suitcase and check if there are visible damage, chips or cracks on it. If you notice that something is wrong with the tool, then it is impossible to use it in any case, since it can be unsafe. Be sure to make sure that the screwdriver battery is charged, or the screwdriver itself is connected to the network. When these conditions are met, the screwdriver is included in idle strokes and check the correspondence of the rotation of the nozzle and thread on the fasteners. If all conditions are fulfilled, you can safely start work.

Do not forget to choose and correctly fix the nozzle or drill depending on where and how you are going to work. How to fix them, we mentioned above when we talked about the change of nozzle.

With direct use of the device, it is also necessary to observe a number of simple rules and requirements.

Pay close attention to the screwdriver itself. It contains a special scale, rotating which is the possibility of regulating the power of the tool. When turning the scale, set the mode you need, focusing on what kind of work you are doing now.

Switching between these capabilities of the tool is quite easy and simple. It is only necessary to hold the screwdriver by the handle located above the battery. Most often the handle is covered with a material that is rubberized. That is why such a processed handle is safe during operation and gives a guarantee that the screwdriver will not fall out of your hand when working. For greater reliability, the tool is fastened to the hand with a strap.

Use options

The correct use of a screwdriver is its use according to the instructions or the established documentation. According to these documents, the main field of use is directly the ability to screw and twist various fasteners, as well as for drilling various holes.

Depending on the possibilities, this or that model can be used both in everyday life and in the professional field. Household screwdrivers are cheaper and have slight power, while professional models have increased power, high rates and wider functionality for use.

But some users use a screwdriver, for example, for non.Standard things such as polishing a car to stir mixes or paint, for grinding various surfaces, for twisting wires, knitting reinforcement, and even to drill holes in ice.

Additional Information

We hope our information resource helped you, and the question of how to drill concrete is no longer bothering you. Good luck!

The drill can be used ordinary for metal. Though after this work it will instantly be dull and then it will have to be hidden to drill the metal. If the screwdriver is struck, then you can apply a drill on a brick with a carbide attack at the end.

Work rules: tips

When working with tools, it is necessary to follow the safety rules and general recommendations:

• 1) Performing work protect the respiratory system, dust is harmful.
• 2) if you work outside, then you need to put fences 2.5 meters.
• 3) When performing work at an altitude of more than 1.5 meters, use a strong base. Forest or goat.
• 4) Working as a tool, the turns must be turned on smoothly, and in no case should you turn off when it is in the body of the wall.
• 5) when drilling through the plaster, it is necessary to carefully study the communications plan so as not to hurt anything.
• 6) it is strictly forbidden to drill through a decorative coating.
• 7) Choose the right cord for each surface.
• Move the drill with water so that it does not overheat.

Drilling with a diamond crown

In fairness, it is worth writing about such a method as drilling concrete with a diamond crown.

There are special drills for diamond drilling, which are quite massive devices that are drilled with diamond crowns. And theoretically, such a crown can be adapted to a screwdriver. In these crowns, the seat is a small rod with a 1/2 inch thread. And if you have a 13 mm cartridge on your screwdriver, and not 10, then you can squeeze such a crown right behind this rod.

If the cartridge is 10 mm, then you need to come up with any adapter.

However, this story has one fat “but!”, Which completely crosses out all these plans. And this is “but!”. The price of a crown that is comparable with the price of a new punch, and often even more expensive. Therefore, this method can be immediately thrown aside.

Thus, the concrete can be drilled with a screwdriver, but it will be difficult to do it. In fact, the main work will be completed by the punch. During the Soviet Union, people in concrete actually made all the holes precisely by the punrate and did without screwdrivers or drills at all. Scurop reverlet in this case only a few simplifies work.

Therefore, again, I recommend getting a perforator. For example, on the site all.Tools.Ru the cheapest punch can be bought for very funny money. You can make sure that by clicking here.

Is it possible to drill with a screwdriver

So that you can correctly drill a concrete wall, you must have the necessary equipment, do all the work carefully and adhere to the following recommendations:

• Without a perforator, the work can be done with a shock drill or drilled with a screwdriver;
• Do not buy cheap drills, as they quickly disappear the winning tip, and they fail;
• Instead of a punrate, you can use a winning tool, one will break crushed stone, and the second, inserted into an ordinary electric drill, drill;
• To work with concrete, the perforator must have a SDS-Plus cartridge;
• Consider the placement of the reinforcement to determine where it is, you can use the metal detector, if the reinforcement is exposed, it must be painted to prevent rust;
• To work with concrete, you can use universal drills with diamond spraying, but you need to insert them only into a conventional drill, or you need to turn off the shock mode.

How to drill?

Work is quite difficult and requiring a lot of effort. But nevertheless leads to the desired result. That is, the work that the punch does on the go, in this case, you will have to make a punch manually.

If you replace the reinforcement during work, then change the place of drilling. Of course, you can try to drill the reinforcement with a drill for metal, but this will be an even more laborious process, so it is easier to change the place of drilling.

Than drill large holes

Many are interested in whether it is possible to drill holes of different diameters with a screwdriver. It is possible, but at the same time the tool should be equipped with additional devices.

• Crown (for metal products). A small circle of a certain diameter with sharp edges. In the center you need to place a drill to break the metal. The crown at low power makes a hole or hole of the desired diameter. During operation of the edge of the crown and the surface of the material, it is necessary to cool.
• Several stages. Drills of various diameters are needed here, from less to greater. You need to start with small diameter drills, gradually increasing, depending on the width of the hole.
• Cone.

The above methods are suitable for working with metal. But if desired, they can be used with other materials.

Is it possible to drill concrete with a screwdriver drill with a drill

Many construction processes require concrete drilling. Screwdriver. This is a tool that can cope with this task.

Design and technical characteristics

Outwardly, as with mechanical exposure, the screwdriver resembles a drill. The difference lies in a low speed / high moment of scrolling. In addition, fixed speed indicators are installed on the screwdrivers (they are self.Regulating on the drills). Speed ​​control is necessary for safe and high.Quality work of the tool. The cartridge stops moving when the screw is completely tightened. Despite the stop of the cartridge, the engine is still working.

For a specific type of work, a specific speed / mode of operation is calculated. There is a function of turning, tightening, unscrewing screws (as well as nuts, screws, screws, soft materials). Masters constantly use screwdrivers. In some cases (drywall, interior finishes, partitions), the tool increases speed and performance several times.

Is it possible to drill with a screwdriver? Ecommercemarket.Ru

Manufacturers offer a variety of tools. Almost everyone can choose a tool for their financial capabilities and specifications. Sprhers can be found more and more often in a home workshop. So there are questions that can be done. Today we understand whether it is possible to drill with a screwdriver?

Experts do not recommend working with concrete. Such durable material does not stand even a drill with good technical characteristics. But if your model has a shock function, then you can try to cover with thin concrete, stone or brick. As a rule, modern designs are erected from aerated concrete or silicate brick. Such surfaces can be drilled using a conventional model that does not have a shock function. The main thing is to use the correct drill.

What can a screwdriver do without problems? If you plan to work with wood, gypsum, metal or plywood, you can safely purchase a tool. This will not only fasten the screws, but also come in handy for drilling.

• What can be done from a burned drill
• When you can work in a drill in an apartment
• What can be done from a hand drill
• Is it possible to use a drill as a screwdriver
• Drill speed adjustment without power loss

To safely use a drilling installation, you must choose it correctly. What to search? If you always want it to be ready for use, purchase a network device or battery, but with a spare battery. The ability to drill different materials is affected by the speed of rotation. For example, 500 revolutions per minute enough to twist. For the drill function, the speed should be up to 1300 rpm. It is also important to pay attention to torque. If it is small, such a screwdriver is suitable only for drilling wood.

Councils of specialists

So that you can correctly drill The concrete wall, you need to have the necessary equipment, do all the work carefully and adhere to the following recommendations:

What to take into account when buying a winning drill for a drill

By concrete for such a power tool as a drill, drill can be bought in a set. This will allow if necessary to use the nozzle of the required diameter. It is the diameter that must be taken into account before buying a drill.

When choosing a diameter, it must be borne in mind that the size of the cylindrical part is indicated on the drills on concrete. When the holes are made, the hole is expanded due to special plates on the nozzle head, which have a slight ledge up to 1 mm. That is why, if it is necessary to drown a dowel with a size of 6 mm in the hole, then for drilling you will need to equipment with a size of 5 mm. This must be taken into account even at the stage of choosing a nozzle. If a large diameter hole is drilled, and the dowel does not hold in it, and is shed, then there are special sealing devices for this.

In addition, the nozzles under consideration are of different lengths, which allows you to make holes of the corresponding depth. When buying, it is necessary to take into account the manufacturer. Often cheap drills are made by little.Known or not well.Known firms. Not always, but often such cheap drills on concrete, quickly fail. The cutting edge is blunting on them, and therefore the equipment in the future does not cope with its task.

If you need to purchase high.Quality equipment for a drill, then you should choose models of well.Known manufacturers as Bosch, Makita, Metabo and others. If there is a drilling of brick, ceramics or reinforced concrete, then for such work it is better to use drill with diamond spraying on the head. Diamond types of equipment are considered the best in relation to the drilling of high.Strength materials. In addition, depending on the quality of the equipment, they work for a long time.
