Screwdriver from the network or battery which is better. Choose a power screwdriver. What are the rules for using a corded screwdriver?

If you take corded screwdrivers into account and compare them with battery-powered models, then corded tools can be more productive, allowing you to work continuously. Choice corded screwdriver is a responsible matter, therefore, in order not to make a mistake in choosing the right tool, use the material that we have prepared for you.

When choosing a power screwdriver, you should carefully evaluate it operating parameters. The most important of them are:

Power parameter. This criterion is intended to determine the basic performance of the tool and its physical weight. As a rule, for home use, a rated power of 450-650 W is enough.
torque setting. The indicator serves as a direct guide to the performance of the tool, characterizing its possible force with a running bit. In addition, the amount of torque indicates the possible material that the device can handle and determines the diameter and length of the fastener.
Reverse mechanism support. The presence of this technology on board the unit makes it possible to use the tool as an “extractor” of fasteners.
The criterion for the number of revolutions and their adjustment allows you to effectively use the tool everywhere.
The ergonomic factor characterizes a comfortable grip, compact weight of the device and other characteristics that are designed to provide a comfortable option for using the tool.

Best network electric tools have all of the above characteristics. As numerous experience shows, having a tool with a base power of 300 W, you can work with thin metal surfaces by screwing in the screws. The most critical operations are best performed using a unit whose base power exceeds 650 watts. Here it is already appropriate to talk about the professional category, where you can often find modifications with a power of up to 850 watts.

Which screwdriver is better - mains electric or cordless? The answer to this question depends on the goals that the master sets for himself - if the working conditions do not imply the presence electrical network, then the battery pack will be better; if the power of the device is important in the work, the network unit will always give odds to the battery one.

What types of network screwdrivers are relevant? + (Video)

First of all, the difference in network units is due to typical device chuck and bit holding mechanism.

The tool chuck may have a toothed structure, which, in the form of a nozzle, is fixed to the fixtures of the device with a key. It is noteworthy that although this process has to spend some time and effort, but it is this mounting option that is characterized by absolute reliability.
A tool equipped with a keyless chuck is quite convenient to use, since the mechanism itself is quite light. Nozzle change is as fast as possible. However, if you have to work with solid materials, then you can doubt the reliability of the nozzle. Therefore, it is most rational to use the unit in this configuration with one- or two-sleeve cartridges in everyday life.
Special cartridges for bits. Such equipment is intended exclusively for special devices, but there are modifications in the classification of professional tools, for example, a drill driver is widely used.

Considering the modern range of network units under the prism of other differences, you can see that the devices also differ in the diameter of the cartridges. Therefore, the choice of nozzle power for the corresponding tool will also be classified. If it is not professional tool, then a cartridge with a diameter of 0-20 mm is considered the standard.

Regarding the presence of a functional feature in the form of a drill on board the device, it is important to note that in this configuration, the models have two basic speed controllers:

from 0 to 400 revolutions (for working with a fastener);
400 to 1300 rpm (using drilling mode).

An important criterion for a modern screwdriver is the type of engine, which can be equipped with or without brushes. The second option is more expensive. The engine runs with less noise, starts smoothly and is not demanding in terms of maintenance. But a motor with brushes may require additional care, for example, to replace them. However, if you purchase a tool from the manufacturer, then the kit will certainly contain additional set brushes.

What models of corded screwdrivers deserve attention? + (Video)

Choosing the best cordless screwdriver To make a choice of a high-quality and inexpensive network unit for home use or professional needs, then take a look at our small power tool rating that deserves attention.

Interskol DSh-10. A relatively inexpensive screwdriver equipped with a 260-watt motor with a non-impact mechanism. The weight of the device is only 1.4 kg. Due to the anti-slip coating, the tool lies very securely in the hand. The keyless chuck is securely fixed at the base of the engine, the torque of which is guaranteed by a maximum value of 25 Nm. As an additional functionality, there is a two-position speed control.
Bosch GBM 6 RE. A very good network tool, which is equipped with a 350-watt shockless mechanism, but with functional support for the “drill” mode. The reversible chuck has a quick lock and is equipped with electronic speed control. The maximum weight of the device is only 1.2 kg. The product is made from reinforced plastic. The torque criterion is equal to the value of 12.3 N * m, when the maximum speed threshold is set to 4000.
Energomash DU-21500. Another not expensive option for a network device, which can be attributed to the semi-professional segment. The model has a drill function and has a power of 500 watts. The rotational threshold is fixed when it reaches 2600 rpm. Included with the device is a set of additional brushes.

What are the rules for using a corded screwdriver?

An electric screwdriver requires the owner of certain skills to use. It is important to take note of a certain set of rules in order to safely use the device at home and at work.

Since we are talking about the network version of the screwdriver, it is important not to forget that this electrical appliance which is connected to the power supply. Therefore, there should be no options for interacting with moisture. It is quite likely that there is a risk of a short circuit or damage to the individual modules of the device, leading to a breakdown of the tool.
Properly observe your own safety precautions, for example when changing attachments. Make sure that the tool is de-energized before changing the attachments. There is a risk of hand injury. In addition, with a high degree of probability, the fastening mechanism itself can be damaged.
Select the operating mode of the tool should be based on the required tasks. Mandatory before new job check desired settings RPM and related power.
And, of course, whichever unit you choose, make sure that it does not have wire damage, dangerous kinks or bends.

We hope that the material of the article was useful for you and you were able to learn how to choose a corded screwdriver, which cordless screwdriver is considered the best and how to use a corded tool correctly.

In the process of repair and construction, the question always arises of which cordless screwdrivers are better and how to make the right purchase in a market filled with so many different firms?

A screwdriver is one of the most used tools.

If you decide to assemble drywall shelves, screw screws into the wall, build a dog house, make a gazebo in the yard or assemble furniture, you cannot do without this tool.

This is a universal tool that can replace several at once, for example, a drill, which is why it is so necessary for home purposes for anyone who decides to do repair work.

However, no matter how versatile a screwdriver is, it also has its pros and cons.

And since you are reading this article, then you are probably thinking about buying it.

We will tell you about all the intricacies in this article and help you choose exactly the one that is useful to you for home and work.

Of course, it’s impossible to say that one tool is bad and the other is good, each company has certain requirements and applications for its tool, for example, some manufacturers have a screwdriver equipped with an impact function, it also combines a drill, such a tool is suitable for making holes in concrete and tree.

Among this rich assortment it is up to you to choose, we will only describe in detail the characteristics and selection criteria.

Corded and cordless tools have their advantages, and which screwdriver is better is up to you, our article will tell you what would be wiser to choose for specific purposes, talking about the main features of each of them.

Battery device

Independence is the main advantage. With an independent battery backup, it does not need a constant power source.

With such a device, work can be carried out even where electricity has not yet been conducted.

Mobility - independent battery allows you to work without difficulty on high altitude, it does not interfere with frequent job changes, the absence of a wire prevents snagging, and it does not cause inconvenience in use.

Limited charge. Despite all the advantages of a cordless screwdriver, it requires a periodic power source for charging.

Therefore, when purchasing a cordless screwdriver, it would be wise to buy two batteries for it at once - while one is charging, the second one can work.

network device

Uninterrupted workflow - with a regular power supply, there is no need to interrupt for charging.

Lightweight - the corded tool is lighter than its cordless counterpart, which will allow them to work tirelessly for longer.

Cost - the network device is cheaper, and only its technical characteristics affect its price, there is also no need to spend money on additional batteries.

Professional and household - which is better?

Any tool called "professional" inspires much more confidence in the buyer.

Screwdrivers equipped with a shock wave, combining a drill, are no exception, and have become a universal tool.

When you buy such a model, you are sure that the service life will be long and the functionality will be extensive.

But the price of a professional tool is many times higher and often becomes a reason in favor of choosing a household one.

The external difference between screwdrivers also takes place, as can be seen in the photo below, a professional tool combines more ergonomic design.

If you're only going to use it for the home, then there's no reason to buy a professional one. The only difference is in the torque - for professional ones it is 130 Nm, for household ones it is 15 Nm.

So, for tightening or unscrewing screws, self-tapping screws are enough for 10 Nm. Therefore, in some cases it will be wise to opt for a screwdriver for the home, in order to save Money.

A professional screwdriver has one important difference - the battery is fully charged in no more than an hour.

So, when making a choice, consider what is more important to you - saving time or money. For most buyers, waiting 3-5 hours for a household screwdriver to charge is not so important.

The main characteristics of household and professional screwdrivers

Household screwdriver:

low cost;
low performance;
low power;
simple assembly;
cheap spare parts;
small battery capacity.

Professional Tool:

high build quality;
powerful motor that can withstand heavy loads;
long and fast battery charge;
convenient design, easily "sits" in the hand;
high price corresponding to the quality;
reliability of work;
impact resistant housing.

To choose such a device, you need to approach the matter seriously and responsibly, this is a very complex mechanism.

And the main determining factors when choosing are:

Firm;
Price;
Convenience.

Let's go over these points in more detail.

Firm

In building stores, products of such firms are mainly presented as:

Bosch (Bosch, Germany);
Makita (Makita, Japan);
AEG (AEG, Germany);
Hitachi (Hitachi, Japan);
Hilti (Hilti, Liechtenstein);
DeWalt (Dewalt, Germany);
Black&Decker (Black & Decker, USA);
Metabo (Metabo, Germany);
Interskol (Russia);
Zubr (Russia);
Sparky (Sparky, Germany);
Skil (Skil, the Netherlands).

Of course, it is difficult to choose among an incredibly large number. Most of the presented tools are made in China, this is not always a bad thing.

The debate over which company is better, Bosch, Makita, Hitachi, Interskol or AEG, does not subside. We will have to figure out the choice in the future.

Price

The cost primarily depends on the promotion and rating of the company, so the Hilti brand is not popular with us due to the overpriced price category and low performance.

Although the service is on top: free service service center within two years from the date of purchase, an employee of the company will come to a place convenient for you, pick up the tool, repair it free of charge and bring it back.

The company has a lifetime warranty. After two years of use, the appliance will be charged a repair fee of up to 33% of its value.

But, unfortunately, according to reviews, the tool of this company breaks down very often.

Such a device is useful only at a construction site, where the tool is provided by the foreman, where it will often be dropped, in which case the guarantee will play a positive role.

But still, for this price, you can buy 2-4 Bosch screwdrivers of similar characteristics. For the price of a home, an Interskol screwdriver is best suited.

This is an inexpensive and very high-quality technique, although it is not ergonomic, it looks rather rude.

comfort, size

This item is completely irrelevant for use at home. But it is indispensable for craftsmen who use a screwdriver for hours.

In this case, size matters a lot. A small tool is more comfortable to hold, the hand does not get so tired, they can crawl from the most hard-to-reach places, but it is also more difficult for them to screw in a screw.

Now about convenience. Before you purchase the device, you need to pay attention to the angle of the handle in relation to the barrel.

If it is too sharp, as shown in the photo below, then with regular use, the result will be a permanent callus between the thumb and forefinger.

Screwdriver battery - types, characteristics

This is the most important point when choosing.

AT modern devices Three types of batteries are used:

nickel-cadmium;
nickel-metal hydride;
lithium-ion.

Advantages of nickel-cadmium batteries:

This type of battery can be stored in a completely discharged state;
Low cost;
Not afraid of low temperatures;
Restorability after long lying.

Disadvantages:

Relatively short time of remote work;
The battery can only be charged after it has been completely discharged. Otherwise, the duration of its charge is reduced;
Fast discharge, after fully charged in an idle position for a week, it is completely discharged.

Advantages of nickel-metal hydride batteries:

Environmentally friendly;
Small size;
You can put on a charge with a large percentage of discharge, the duration of the charge does not decrease much.

Less operating time than nickel-cadmium batteries;
The price category is higher in contrast to nickel-cadmium batteries;
Discharges by 10% during the first day;
It is forbidden to store in a discharged form;
Fear of sub-zero temperatures.

Nickel-metal hydride batteries are now almost non-existent.

Advantages of lithium-ion batteries:

You can put on charging at any percentage of the discharge;
Self-discharge no more than 20% per year with proper storage;
Fast charging time (from half an hour);
Long service life, 5 times longer than nickel-cadmium batteries.

High cost of charging and battery;
It is impossible to start charging with a completely discharged battery;
Does not tolerate sub-zero temperatures.

Follow all these rules, and you will be able to buy a screwdriver that will delight you while you work.

A screwdriver is a tool that every owner should have. Which screwdriver is better to buy for housework - consider the rating of the best and the rules for selecting this indispensable household helper.

First of all, you don’t have to chase the cheapest one, even if you only need the tool at a time. The manufacturer and model must be selected depending on the following technical characteristics of the tool: speed, power, operating mode and other parameters. Next, we will present in more detail all the information about the choice of screwdrivers and consider the most popular of them.

Modern screwdriver

A screwdriver is a universal device that is actively used in everyday life. The purpose of such a power tool is to tighten and loosen screws, self-tapping screws.

There are dozens of models of such tools in stores, which are divided into several categories. Before choosing a screwdriver, you should determine the criteria and conditions under which it will be used.

The price range of the described category of power tools is wide, so everyone can choose a model for themselves according to the estimated budget.

The choice is highly dependent on the operating conditions. For home use only relevant technical specifications. Professional use will require more expensive and powerful versions with a removable battery.

Choosing a tool for home and work

To make the right choice and buy a suitable screwdriver, you need to decide on the selection criteria. There are not so many of them, and the process itself seems simple, but in order not to regret the purchase later, it is better to clarify the nuances that may not be known to everyone.

The most important thing is to determine for yourself with what frequency and intensity the tool will be used. If you need it to screw in a few screws once or twice a month, the most budget model is enough. However, for more frequent use choose carefully and thoroughly.

A common mistake is to choose the cheapest model to use the tool for only a couple of days, but under heavy loads. For example, to assemble a metal structure (like a garage), or install fences in a country house, the first cheap model that comes across is not very suitable.

The first question that buyers of such a device ask themselves is the type of power supply. Today, models are offered with a power cord (the tool only works from a 220 V outlet), as well as with a replaceable battery.

Before choosing the right cordless screwdriver, it is necessary to determine in what conditions and for what purposes it will be used. The fact is that battery power is limited, so a quality screwdriver model with a power cord can be more powerful.

On average, one battery charge is enough for 100-250 screwed self-tapping screws or screws. With an increase in battery life, the power of the device decreases, which increases the twisting time and increases the load on the motor.

The capacity of the battery itself is also limited. The manufacturer indicates that it is enough for several hundred charge and discharge cycles, after which it will be necessary to purchase a separate component for a specific model.

Difficulty may arise if the owner has had a screwdriver for a long time, and this version is no longer available. Therefore, you will have to spend some time to find the right battery, identical in power and mount.

They have cordless screwdrivers and their advantages, which are the autonomy of work. Network models usually have a cord up to one meter long. This is not enough even to connect the device to the nearest outlet, so you always have to use an extension cord.

If work is carried out outside the garage or at home, additional expenses will be required. It is also difficult to work with a network tool at height (for example, if you are assembling frames, tall furniture, structures, awnings, arbors, garages, and the like).

Therefore, before choosing a cordless screwdriver, you must determine how important autonomy is to you. After all, corded power tools in this category can cost several times cheaper than options with a removable battery.

Corded screwdrivers are more affordable. They differ in the same level of torque, regardless of the operating time. Minimum speed rotation is 250-300 rpm. This is enough to drill holes in boards up to two centimeters thick and screw self-tapping screws into them.

To work with thicker material, you should select more powerful model. The average value for heavy duty work is 750-1300 rpm.

Specifications

To know which screwdriver to choose, it is also necessary to have knowledge of the technical parameters of each category of power tools. Before choosing a cordless screwdriver, you need to pay attention to the type of battery. This will affect the duration of the device from a single charge and the overall battery life.

The following types are distinguished: Ni-Mh (nickel-metal hydride), Ni-Cd (nickel-cadmium), as well as Li-Ion and lithium-polymer (Li-Pol). In the first case, it can supply a large current, but the service life of the device is less than that of other batteries. Devices with a Ni-Cd battery have a large energy capacity.

Nickel batteries are less commonly used because physical properties they are prone to discharge if left unused for several weeks. Lithium batteries more practical, but they are not without drawbacks. For example, in extreme cold, battery life is reduced by 30-50%. The optimal capacity parameter is 2 Ah.

Pay attention to this indicator when choosing to ensure stable operation of the device for several hours.

In the description, the indication of the operating mode is most often found, as “unstressed and reverse”. This means that the screwdriver can only be used in the standard mode of rotation of the nozzle in one or reverse side. Minimum power is 400-800 watts.

For professional use, 1000W or more will be required to ensure stable and smooth operation even under high loads. Low values relevant for cordless screwdrivers, which are designed for simple tasks.

Criterias of choice

Corded screwdrivers are selected by power, by the type of cartridge and by the speed of rotation of the nozzle. In the first case, it is necessary to select models with minimum power at 600 watts, as mentioned above.

It is also necessary to take into account the parameter of the rotation speed of the nozzle. The higher it is, the smoother and more stable the drill or screwdriver will enter wood, metal. At a low rotation speed, work on metal is difficult, and the risk of overheating of the motor also increases. The cartridge diameter in most models is 10 millimeters, which is the standard.

In the list of characteristics there is an item about the type of cartridge. Today, keyless or hex chucks are isolated. The first option is more practical everyday use, since the replacement of the nozzle does not require the use of a separate hex wrench.

Single sleeve or double sleeve chuck is tightened by hand. The first option requires less effort - this design is often installed on expensive screwdrivers.

The hex chuck requires bit clamping with a separate wrench, which is included with the device. Additionally, such screwdrivers are always equipped with bits with different tips, which can be changed with one hand, and then tighten the connector with a small wrench.

When choosing, it is important to pay attention to the total weight of the tool. Models with a battery weigh 0.5-1 kilograms more than the mains versions, which can lead to inconvenience during prolonged use.

If the screwdriver weighs up to two kilograms, this will reduce the accuracy of its use and accelerate the onset of physical fatigue of the operator.

Few notice such a detail as the location of the handle. Some models of power tools have a standard "pistol" shape, while others have a handle shifted to the center to stabilize the center of gravity. The second option is more convenient for frequent use - the load is distributed and centered in the handle itself, which requires less effort.

In today's market there are a large number of models of screwdrivers for every taste and budget. In order to accurately select a tool for your purposes, you need to familiarize yourself with the main advantages and disadvantages of specific options and the characteristics by which the division into types is carried out.

First of all, when choosing a power tool, it is necessary to clearly define the scope of its use. Often, the household segment of power tools has a much lower cost, unlike the professional one.

The second distinctive feature of home appliances is their characteristics: such a tool may not have all the functions of high-end models, may not have increased power, performance and hardened body, yet it is brilliant for everyday work in the home or workshop.

An amateur mini screwdriver most often works with batteries, which makes it mobile and practical.

Professional models are designed for long-term work in conditions increased loads. Such large and heavy tools are usually mains powered, which ensures uninterrupted and long-term operation, provided that there is stable access to the mains.

Additional functions of screwdrivers

Manufacturers can add additional functions for power tools. They do not affect the power or efficiency of work, however, if they are present, the use of a screwdriver becomes more comfortable.

Among these functions, one can single out the presence of a backlight near the handle to illuminate the working area (simplifies the use of power tools in a dark place). Also noteworthy is the pulsed mode of operation, in which it is easier to work with soured screws, self-tapping screws.

Mains or battery

As mentioned above, electric screwdrivers are divided into two large groups: mains-operated and those that operate using rechargeable batteries.

Batteries make devices larger and heavier, while “networkers” are characterized by lightness, but binding to the place of use;
network models are more often used for professional work, and battery models for short-term use;
if there is a stable connection, corded screwdrivers work for a long time without overloads and excessive heating, and battery ones will have to be changed or recharged;
the cord tends to get tangled when working with a network device; with a standalone model, you can forget about such problems.

The popularity of cordless professional and household screwdrivers is due to ergonomic design, quality and independence in work. Due to the high demand, it is worth stopping at these models and considering the types of batteries used.

Before you choose a screwdriver for your home, garage and cottage, you should decide on the source of its power. Network models use a regular household network for this, and battery-powered devices are equipped with a removable battery. Each type has its pros and cons.

Cordless screwdriver is good for its autonomy. It is conditionally independent of the outlet and can be used even in open field. This expands the scope of such a tool. However, the battery also imposes limitations.

The first of these is limited time. Usually the charge is enough for a hundred or two screws, but in difficult conditions, autonomy is reduced. The second disadvantage is limited power (torque).

It may not be sufficient for working with hard and durable materials. There are positive exceptions, like the professional Makita DTD146Z, but they are not cheap.

A corded cordless screwdriver is a tool with higher power and rotational speed. It copes well with tightening screws and self-tapping screws, can be used in drilling mode, and due to the absence of a heavy battery, it weighs less. A constant power supply allows you not to think about saving battery.

However, far from the outlet, it will be possible to work with such a screwdriver only if there is a long carrying or a generator. Here, too, there are exceptions, but unpleasant ones: the cheapest Chinese models are not more powerful than their battery counterparts, but they are also not autonomous. The minimum acceptable choice is something like the Dnepr DE-850.

Which screwdriver to choose - corded or cordless - depends on the needs and expected operating conditions. If the tool will not be used outside the house, apartment, garage and other premises, network is better. It's cheaper for equal power, lighter, and ready to go anywhere, anytime.

The cordless screwdriver is optimal for outdoor use, including outside settlements. At the same time, it is advisable to choose models with a capacious battery, at least 2 Ah.

Which type of battery to choose

Nickel-cadmium batteries

The undeniable advantage of this type of battery is its low cost. Ni-Cd batteries are most often used by manufacturers in creating budget lines of power tools. Another advantage is the five-year warranty period, which exceeds the standard by 2 years.

Nickel metal hydrate batteries

They differ high level environmental friendliness and are increasingly being used in the production of high-end cordless tools. The dimensions and low weight of the batteries make the tool itself much lighter and more convenient. Perhaps the only drawback of Ni-Mn batteries is their high cost.

Li-ion batteries

These batteries are considered the best for mobile power tools. They hold a charge for a long time, charge very quickly, and they also have no charge memory effect. The only disadvantage of Li-Ion batteries is the high cost.

the total voltage in different batteries is from 10 to 24 V, the power of the device depends on it and affects the duration of operation;
the material of manufacture of the battery affects the capacity of the batteries;
loss of battery capacity due to charge memory effect.

A cordless screwdriver, the price of which depends on the type of battery and other characteristics that are important for high-quality work of any complexity, is a popular tool in every home.

Power and torque

The second thing to consider before choosing a screwdriver is its power and torque. Very often, sellers indicate the power, but do not indicate the torque of the model and hush up the power of cordless tools.

With power, everything is quite simple: 600-800 W is more than enough for non-professional (home) use, if you do not also need to drill a lot. But the torque - it is worth considering in more detail.

The torque (measured in Newton meters - N * m) of a screwdriver determines how much force it can apply when tightening a screw. The higher this value, the harder and durable materials screw will be included. With a lack of torque, the transmission mechanism of the tool will stall, and the screw will get stuck halfway.

In order to tighten small self-tapping screws (up to 50 mm) in not very solid wood, any screwdriver is enough. However, for working with hard wood, the torque must be at least about 15 Nm. For longer screws and self-tapping screws, 20-30 N * m are needed, and models with 40 N * m and more will cope with twisting "hundredths" into a solid beam.

Rotational speed

For a household screwdriver, the speed of rotation is not a fundamentally important parameter. The tools are equipped with a reduction gear that converts the high RPM on the motor shaft to the low RPM on the chuck.

A couple of hundred revolutions per minute is enough for screwing, and high speed rotation is fraught with jumping bits. This leads to both premature wear of the nozzles and licking of the slot of the screw head.

Before choosing a screwdriver with drill functions, you still need to pay attention to speed. When working with solid materials, there are not enough of them. 1000 rpm is the minimum suitable for materials with similar hardness, and 3000 rpm will not interfere.

Cartridge type

Another point to consider when deciding which screwdriver to choose is the type of chuck. One-Stop Solution is a keyless chuck in which the bit is fixed by rotating the clamping ring.

It allows you to use not only bits, but also drills, heads for tightening nuts. You can also insert a mixer nozzle for mixing the solution, a grinding brush "umbrella" into a similar cartridge.

The hex bit chuck is good in that it reduces the weight of the tool, and also allows you to quickly change bits. They are held in it with a special latch or magnet and removed with a little effort. However, the drill cannot be inserted into such a cartridge.

There are exceptions - these are models that are also equipped with a removable keyless chuck. They are the most versatile, since it is easier to turn the screws with them, and can be used for other purposes.

Review of popular brands

How to choose a cordless screwdriver, which company is better? To simplify final choice models, it is necessary to indicate the most popular brands under the logos of which modern power tools are produced. Durability and cost partially depend on this, so the choice of a particular manufacturer should not be neglected.

Makita- Japanese company, which produces high-quality power tools (founded in 1915);
Dnipro-M is a Ukrainian manufacturer that develops and manufactures power tools in an affordable price segment (most of the models are made in China);
Bosch- German company, which does not require a separate representation;
Vertex is a Taiwanese power tool company;
Forte is a certified Ukrainian manufacturer of power tools.

findings

In order to immediately know which screwdriver to buy for home or work, you need to study the working conditions described above, as well as the factors for choosing a tool. The following is an objective list of the advantages and disadvantages of each type of device.

Preservation of rated power, regardless of the operating time;
Ability to work unlimited time without interruption for recharging;
Lower cost of power tools compared to battery versions.

Difficulty working at height (it is difficult to keep the tool straight along with a long wire and extension cord);
It is impossible to work without an extension cord and a 220 V socket ( work zone while limited to a few tens of meters from the outlet).

Based on the list of advantages and disadvantages, it is relevant to say that a corded screwdriver is optimal solution for an apartment or a private house. At the same time, it is necessary to stock up on an extension cord of 5-20 meters in order to ensure freedom of movement with a power tool in your hands.

The average resource of such devices is not limited. According to users, on average, one model can withstand 2-4 years of active operation.

Ability to work remotely, regardless of the proximity of the outlet;
Possibility of development of high turns of a nozzle.

Among the shortcomings, one can single out a limited operating time, limited battery capacity and poor power of cheap models.

If for work or at home you need a device without a network cable, it is more important to take high-quality, expensive options cordless screwdriver. This will shorten the time required for charging and provide stable power even when working with hard materials.

Sooner or later, the owners of the house are faced with such a need as the use of a screwdriver. It is necessary when you need to assemble furniture, replace a lock, hang a picture, fix drywall or baseboards, install a door, and in many other everyday situations. Those who find it a bad habit to borrow an instrument from friends or neighbors are more likely to go out and buy their own. But what about a person who knows little about screwdrivers? And the front of work at home with this equipment is considerable? How not to make a mistake with the necessary parameters and which screwdriver should be chosen for the home - this will be discussed later.

There are two types of screwdrivers: cordless and corded.

We determine in what works the device will participate most often?

If you turn to any power tool store, it becomes clear that choosing a screwdriver without knowing absolutely nothing about this type of tool is not an easy task. Because the offer is huge. There are many manufacturers of such equipment competing with each other and positioning their product as the best. An ignorant person's eyes will diverge from the diversity of this proposal.

Therefore, the most fundamental criterion when choosing this tool is the expediency of its use.

If the device will be used for one-time repairs around the house, then you should choose an inexpensive model with minimum set functions.

If the equipment is planned to be used in a home workshop and it will often have to be used for certain highly professional tasks, for example, drilling metal, then its set of functions should be quite wide.

What technical parameters should you pay attention to in the first place and which screwdriver to buy?

Battery or mains?

Keep in mind that the models are both battery-powered and powered by electricity. What is the best screwdriver to buy in the house? Rechargeable batteries are easy to use due to their mobility, they are not tied to the network, they can be carried with you anywhere. No need to think about the length of the wire, the availability of sockets, extension cords, and so on. But for uninterrupted operation such a tool, they need to be recharged, which will take time. The mains power tool is indispensable when working with metals.

If the choice is made in favor of a cordless screwdriver, then the type of battery should also be selected. There are three varieties of them: lithium-ion and nickel-cadmium, metal-hybrid. Here they are presented in descending order of reliability, price and time to recharge the battery.

Lithium-ion batteries are considered the most practical. They cost more than their counterparts, but stand out for their capacity, the possibility of long-term use between recharging and low weight. Their working condition is 3-4 years, after which they become unusable. They are easy to use and require regular maintenance.

Battery power (9.6 - 24 volts) is an equally important factor in choosing a screwdriver. high power- possibility long work device without recharging, as well as screwing screws into the most problematic places. High power is a sign of a heavy device.

Torque also deserves to be taken into account when buying. Household work can be done at 10-15 Nm. It will be sufficient to buy a screwdriver with 40-40 Nm. Although some of its types can reach 130 Nm.

The rotational speed is another important point in order to choose a screwdriver and buy the one you need. The drilling speed will depend on this value. So to drill more hard materials, you need to choose a tool with high torque. To tighten the self-tapping screw on the farm, 400 rpm is enough. For professionals, this value will not be enough. They will need from 1200 and more rpm.

When buying, consider the moment how comfortable it is to hold the device in your hand. Conveniently? So he is yours.

On the farm, from time to time there is a need to drill a hole, tighten loose furniture, knead glue or mortar. To do this, do not purchase three tools: a drill, a screwdriver, a hammer drill. Buy one corded screwdriver with a drill function, and all problems will be solved quickly, efficiently. Such a tool, unlike a cordless one, has more power, better performance, works for a long time without requiring recharging.

How does a cordless screwdriver work?

Power tools of various brands and manufacturers are endowed with many technical specifications, functions, cases, different from each other. However, their design and basic principle of operation are almost the same. They differ only in small nuances. How network screwdrivers look from the inside shows a photo:

It bears the following markings:

Start button.
Reverse switch.
Capacitor.
Electric motor.
Frame
Reducer
Cartridge.

Screwdriver is powered by 220 volts, equipped with a motor direct current. The reverse button changes the polarity of the power supply, as a result, the motor rotates in reverse direction and the device turns out the screws, instead of screwing in. Gearbox parts are made of metal or technical plastic. An electric screwdriver acquires additional operational functions when equipped with a two-speed gearbox. Speed up to 450 rpm is needed to work with self-tapping screws and screws, and rotation at a speed of up to 1400 rpm allows you to drill holes in metal, wood, plastic.

Advantages and disadvantages of a corded screwdriver over a cordless one

The fact is that both of them have a lot of advantages, but are not without drawbacks. Equipment is not cheap, especially when it comes to branded models. Therefore, make the choice of a network screwdriver after a detailed acquaintance with the instance you like.

Cordless screwdrivers are lighter in weight and smaller in size than cordless ones. Because a battery inserted into or attached to the case makes the tool heavier and adds to its weight.
A 220 V cordless screwdriver does not lose power during operation, while a battery-powered tool gradually loses it in parallel with a decrease in battery charge.
Depending on the conditions of the power supply and the characteristics of some brands of batteries, it happens that while they are charging, you have to stop all other work. A cordless drill driver will not allow such a situation.

Price also matters. The best corded screwdriver is much cheaper than a cordless counterpart.

What to look for when buying a tool

When you stop in front of a shop window or look through the catalog, it is clear that it is impossible to immediately stop your eyes on a worthy device. First you need to know exactly two things: why we buy and how much we can count on. How to choose a power screwdriver decent quality possible, only knowing in advance its prospective tasks. At the same time, it is good to understand which the most important parameters attention should be paid. Of these, we designate:

Power. The weight of the electric drill-screwdriver, its productivity depends on this indicator. For the home, a power of 450-650 W is sufficient, professionals need a more powerful tool.
Torque. It characterizes the effort with which the device is capable of working. This value affects the choice of material and the dimensions of fasteners that this tool can work with. For homework, a torque value of 25-30 N * m is sufficient.
Reverse. Its presence is mandatory when a corded home screwdriver is needed not only for tightening fasteners, but also for removing them.
The speed of rotation and the mechanism of its regulation. Changing the indicator makes it possible to use the tool in different conditions.

Comfort during operation. This includes light weight, comfortable grip, cord length and other properties that allow you to create best conditions at work.

The main thing is not to confuse a screwdriver with a drill. It is believed that if the device is with a battery, then a screwdriver, and if there is a plug, then a drill. This is not an argument. The main difference lies in constructive solution. When releasing start button the screwdriver chuck stops instantly. While the drill is still spinning for some time. That is, in its mechanism there is no run-out brake. But now you do not need to buy these two tools separately. You can choose an electric screwdriver - a drill, which has universal functionality.
