How to drill a concrete wall with an electric screwdriver?

Greetings! This article is about whether or not you can drill with an electric screwdriver in concrete. Sometimes it happens that you need to make a hole or a cavity in the concrete, and besides an electric screwdriver at hand do not have anything. You’ll have to figure out what to do with it. There are of course impact screwdrivers, but even they can not cope with concrete. At the most they can do a brick.

Of course, I still recommend to get a torch for such cases. Even if it’s the cheapest. You can drill a hole in seconds. But if you need to do the job right here and now, you can try the following method. True, for it in addition to an electric screwdriver and a drill will need two more things. a puncher and a hammer.

You can use an ordinary drill bit for metal. but after this work, it will instantly blunt and you have to sharpen it later for metal drilling. If the electric screwdriver is percussive, then you can use a drill bit for brick with a carbide tipped tip.

Types of screws

To begin with, a screw is a cylindrical rod with a special head, to which the screw groove is applied. Screws are produced according to a number of regulations, including GOST 1144-80, GOST 1145-80, etc. д.

Screw

At the same time, there are two main types of metalware. these are:

Carving self-tapping screws on metal and wood To designate in this case, the diameter and length of the screw (for example, a product with a diameter of 5 mm and a length of 3.5 cm will be designated as 5×35 mm). In addition, hardware can be classified according to the shape of the slot and the features of the head itself:

Types of screw heads All of these varieties are made with Phillips, straight (flat) and Torx (the latter is also known as “star”) spline, as well as with internal hexagon and other less popular variants. There are also screws with heads six-and octahedral shape (roofing), which are also made with different slots.

For your information! According to the type of thread screws are also divided into several varieties, which is conditioned, first of all, by the connected materials and the specific purpose (for metal, wood, drywall or small household appliances).

For wood

The main difference between self-tapping screws for wood is the sparse threads, unlike their metal counterparts. Such fasteners can be black, gold and white. So, if you want to screw a golden hinge on the door, then choose a golden screw. In most cases, however, the choice falls on the black self-tapping screw.

For metal

As already mentioned, the thread on such a screw has a frequent pitch. The reason for this is that metal is a rather hard material, so the clutch must be made strong. over, some metals should not be pre-drilled, such as tinplate. As for thicker metals, you will need to make a hole.

Roofing

Such self-tapping screws are used for fixing roofing sheet metal. It is necessarily equipped with a sealing rubber. As a result, the connection, in addition to strength, becomes airtight.

Furniture screw or screwdriver

This type of self-tapping screw requires pre-drilling a hole in the furniture piece. A hexagon wrench is used to tighten it.

These are probably the most common types of self-tapping screws that are used in various areas of construction. Let’s consider the details of how to screw this or that self-tapping screw into different surfaces.

Dowel on concrete. technical characteristics

Self-tapping screws (without drilling the concrete) are made on the basis of hardened steel, which gives the product increased strength. A yellow galvanic zinc coating is applied to the surface. Machining improves the mechanical characteristics and anti-corrosion properties of fasteners.

Phillips screws are ideal for use with a regular hand screwdriver or an electric installation tool. TORX-slot, fasteners with hinges, convex heads, heads with external thread, hexagon (key-type) are used with the appropriate type of tool.

The threads are not evenly threaded. The quality of adhesion of the surface and fastener is improved by special notches. The dowel holds perfectly on porous bases and in hollow blocks.

For mounting objects with considerable weight

For mounting heavy objects (furniture cabinets, shelves, TV stands, etc.).) it is necessary to choose a dowel that also belongs to the percussion type. In this case, the diameter of such a dowel, as well as the transverse dimension of the drill, must be at least 10 mm. These dowels go 6 cm into walls and 8 cm into ceilings. For reliable attachment of heavy objects, usually use at least 6 dowels.

Anchor bolts with a diameter of at least 8 mm are used for fixing the horizontal bar and stairs. Such bolts go 6 cm into the wall surface and 8 cm into the ceiling.

Anchor installation procedure in a concrete wall

Anchor bolts used to secure various objects are divided into three main types:

• Anchor bolts with a nut, which after mounting the fixing element is tightened with a ring wrench or open-end wrench (with such bolts are used to perform fasteners of the hidden type);
• anchor bolts with a self-locking nut, which is screwed with a Phillips-type screwdriver (you can use such bolts to make fasteners in those places that are in plain sight);
• double anchor bolts are the most reliable fixing elements, which are used to fix even very heavy objects.

Tips for drilling in concrete

Users often wonder how to drill through concrete with an electric screwdriver and if it is possible. Concrete is a rather strong material, so you need to consider the diameter of the hole and its depth. If you are going to drill a hole with a diameter of more than 10 mm, then it will be difficult to drill such a hole.

When drilling in concrete, drill bits with a diameter of 3 to 5 mm are used. Pay particular attention to the rpm. If you screw in simple fasteners, 500 rpm will be enough. And for drilling you need 1300-1500 rpm.

Another criterion for working in concrete is the torque. An electric screwdriver with a torque rating of 90 to 140 Nm is the right choice for such jobs. It turns out that the electric screwdriver can drill a wall made of concrete. A tool with this torque is also useful for drilling brick walls.

Some craftsmen use an electric screwdriver to drill a hole in fishing. You need a lot of torque. Selected models by Makita and Metabo tools can cope with it.

an electric screwdriver can easily drill through concrete up to 10 mm

How to drill through concrete with an electric screwdriver?

Which electric screwdriver to choose for concrete drilling?

At one time in many construction processes is the need to drill in concrete. A tool that can cope with a similar task. an electric screwdriver.

Design and characteristics

From the outside, just like the mechanical action, an electric screwdriver resembles a drill. The big difference is the low rotational speed/high torque.

Among other things, the screwdrivers have fixed speed characteristics (in drills, they are regulated without assistance). Speed control is essential for safe, high-quality operation.

The chuck stops when the screwdriver is screwed in. Regardless of the chuck stopping, the screwdriver is still in practice.

Speed/mode of operation depends on the application. There is a reverse function, screwing, unscrewing screws (additionally nuts, screws, screws, soft materials). Handymen routinely use screwdrivers. Other times (work with drywall, interior assembly, creating a partition), the tool increases the speed and productivity of the work significantly.

How to drill a concrete wall with an ordinary drill: expert tips

Concrete structures, walls and ceilings are not uncommon in our homes and apartments. In high-rise construction, they are generally used with particular frequency, as houses with concrete walls come out the most reliable. The reliability of concrete is due to the good strength of such material, which is achieved by using the correct components of the concrete mixture and qualitatively done work on its construction.

And here we are proud of our solid walls. But usually there is a need to drill a hole in this very wall. And it may be needed quite often, for example:

• when finishing walls and ceilings;
• in the installation of air conditioners;
• when installing plumbing fixtures;
• in the installation of furniture
• when working with electrical wiring, its installation;
• the need for a mounting hole for a picture or other interior items.

As you can see, there are many reasons to drill a wall. The main thing is not only to do a good job, but also to make your life easier by using the right good tool. What can be chosen to drill concrete?

It would seem that there is nothing strange: just take an ordinary drill and drill. But no, in fact, in the process of performing this task can be a lot of difficulties. First, concrete walls are very strong and hard to take, and secondly, their structure is not homogeneous, and you easily risk getting caught in the rubble or a piece of rebar. You can get stuck with an ordinary concrete wall for a long time and end up not being able to drill anything.

What to drill a hole with?

The answer to this question will not be overly complicated. The fact is that drilling a wall of concrete, as mentioned above. the process is extremely difficult. To solve this question, it is worth using one of two types of tools: either a peorator, or a drill.

Both will be good in certain conditions. I will explain why. It is best, of course, to use a peorator: it is designed specifically for concrete walls and it is common practice to use it. After all, the peorator easily penetrates both stone and concrete surfaces. Another advantage is the possibility to drill holes of large diameter, which a drill cannot do.

But if you have a wall of foam concrete in front of you, or if you need to drill a few small holes. the drill is quite suitable and. In this case, the peorator can crack the surface of the wall, which is not very good. But, as already mentioned, do not count on big holes, only with a diameter of not more than 12-15 cm. In addition, drilling a concrete wall has its own nuances, which we will discuss below.

How to drill a concrete wall with an ordinary drill?

Let’s talk a little bit about drilling with a regular drill. So let’s start with the fact that an ordinary drill is unlikely to work here. Т.е. Theoretically it’s possible, of course. But in practice it is very difficult. The use of a special pobedite drill bit for concrete work with a carbide-coated tip is mandatory in this case.

The best way would be to use a special impact drill. How it differs from a usual one? In such a drill, the movements of the drill are carried out by special ratchets with teeth that interact with each other. The core drill is easy to use and produces high-quality work. To do this, simply switch the drill from its normal, rotary mode to percussive rotation mode.

But no matter what type of drill you use, as much as the use of specialized bits is relevant. Drill bits are sold in two configurations: for impact or hammerless drilling.

The classification of nozzles is like this:

Tooth bits for drilling with impact function. Concrete walls can be drilled with these bits, which have a cutting edge made of separately soldered-in hard-alloy teeth. For a fast-action drill chucks have these snapped tails SDS. Their strength is so high that it is possible to cut the metal, but only the impact mode contributes to their destruction, creating unacceptable loads. That’s why such drills are used for the purpose of drilling between the reinforcement of reinforced concrete slabs or brick walls.

Diamond drill bit for hammerless drilling. These are more modern nozzles, which simplify the task several times better than conventional. The abrasive edge with cutouts on them is created by diamond spraying or by spraying corundum sand. As you know, diamond is notable for its unprecedented durability. That’s why it can easily handle reinforcement in a concrete wall. Such a nozzle can make a hole even 1.5 meters deep and more than half a meter in diameter. This type of bits is already used by professionals, but the bits with a diameter of up to 100 mm can be quite used in domestic conditions.

Bits of CS: GO standard. Bits with diamond crystals embedded in the cutting edge. Can be used for slabs, rocky soils, monolithic concrete structures of high strength grades. It can easily replace the teeth from hard alloys.

Depending on your conditions, you can safely choose the right drill bit and drill the hole. But there are also a number of recommendations for working with an ordinary drill that is not equipped with an impact function.

To do this, you start drilling into the wall, but periodically interrupt. You need to drive a sharpened drill into the concrete surface by hand and destroy the concrete with metal punches. Take our drill bit, or our chisel, or other metal devices of the corresponding and necessary diameter, and hit it with a hammer/hammer. Periodically rotate the drill bit. Then take the drill again.

Keep in mind that when you drill a hole in a concrete wall with a regular drill, you risk breaking the tool. Be sure to give the low-powered drill a rest. Drills also have the properties of heating, so you need to cool them with water. Make a break every 10-15 minutes of work, leaving the same amount of time to rest the tool.

Why is the concrete wall not drilling. Construction, repair, construction

Making repairs in an apartment or house, there is always the question of drilling a wall. You can use different tools, depending on the purpose of the hole and the material of which the surface is made.

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

Drilling holes in the wall correctly: general rules and recommendations

In order to drill the wall correctly, it is necessary to take into account the material of which it is made, based on this it is necessary to pick up the tool.
