An electric screwdriver is a tool that greatly facilitates repair work. Corded screwdrivers are highly productive and do not require recharging, unlike battery-powered ones. According to owners' reviews, a mains-powered tool is more reliable, since the battery will not run out at the most inopportune moment.
In addition, mains power allows you to develop a greater number of revolutions when using the tool as a drill. Thus, a correctly selected corded screwdriver allows you to quickly and efficiently perform work both at home and in professional activities.
How to choose a screwdriver
The first thing you need to do when choosing a screwdriver is to familiarize yourself with the varieties of power tools of this type. Depending on the type of screwdriver, some features appear with its operating mode, the functionality expands or narrows. In addition to choosing the type, it is important to pay attention to a few more points.
Power type
Based on the type of power supply, all screwdrivers can be divided into 3 groups.
- Network ones are connected via cable to the general power supply network. They cost less and have higher power.
- Rechargeable ones operate from removable batteries. They are not tied to a location and can be used in various conditions.
- Pneumatic screwdrivers. Least popular, shock models. Connect to the compressor.
Power and torque
The performance of the power tool and its general capabilities depend on these parameters. The optimal torque for screwdrivers for household use is 25 Nm. For regular work with various materials, it is recommended to choose a tool with a torque of over 40 Nm.
When it comes to power, there is no point in buying the most powerful screwdriver for home use. The optimal power indicator for domestic use is 0.6 kW. If the tool will be used for various installation work - over 0.9 kW.
Chuck type
The most popular type of chuck is the quick-release chuck. It is suitable for installing various bits, drills, and specialized equipment.
Another possible option is a “bit” cartridge. Suitable for installing only bits for which there is a special latch in the design.
Manufacturer
It is important to pay special attention to the manufacturer of the power tool. Most popular companies:
- Makita – Makita tools are valued among buyers due to their price/quality ratio;
- Bosch – high quality, many available options to choose from;
- Metabo – quality, productivity;
- DeWalt - high quality, additional features, performance, durability.
As for domestic manufacturers, it is necessary to highlight the Interskol company.
Other parameters
As for other parameters, it is necessary to pay attention to a number of points.
- Convenience at work. It is important to hold the instrument in your hands before purchasing and evaluate how comfortable it is.
- The presence of a speed controller, a switch between different modes.
- Work area illumination, bit holder.
Another significant point is the material of the case and the presence of rubberized linings.
What to look for when choosing
What corded screwdriver do you use?
Gun T-shaped
When choosing a corded screwdriver, you should pay attention to the following points:
- Device power - screwdrivers are equipped with motors with power from 100 to 900 W. Optimal for everyday use would be a tool with a power rating of about 500 W.
- Torque is the force with which the bit acts on the screw. This figure varies from 10-15 Nm for household screwdrivers to 250 Nm for professional-class pulse screwdrivers.
- Convenience of switching modes - if the tool combines the functions of a screwdriver and a drill, there should be a rotation speed switch on the body (from 500 rpm for a screwdriver to 2000 rpm for a drill).
- Smooth speed control is especially important if the screwdriver can function as a drill.
- The presence of a power-on lock - this function is present by default in professional screwdrivers, but it can also be found in household ones. However, it must be remembered that household tools are not intended for high loads and long-term drilling, even if they have a drill mode.
Expert opinion
Torsunov Pavel Maksimovich
It is also necessary to evaluate the build quality of the tool - a high-quality screwdriver has a durable body without gaps or backlash. Professional tools are made of reinforced hard plastic or aluminum.
DA-10/12S2
Price: 4000 rubles
The device is considered not just a screwdriver, but a hammerless drill. It received this classification due to its high power. Torque 30 Nm, battery capacity 1.5 Ah. Withstands operation even in cold weather, including when cooled to minus 15. Battery voltage is 12 W, bits can be installed from 0.8 to 10 mm. There is a shock mode, a flashlight, and a reverse. Weight – 1.52 kg.
Pros:
- two batteries;
- fast battery charge, in just an hour;
- compactness;
- shock mode;
- backlight, reverse;
- torque 30 Nm.
Minuses:
- rarely found on sale;
- The rubberized handle quickly begins to “fade”.
Testing of INTERSKOL screwdrivers
INTERSKOL screwdrivers on the market are subject to compliance analysis with regulatory specifications.
During field testing of products with different batteries, an obvious advantage of tools with the Li-Cd battery type was revealed in terms of volume and speed of useful work with both wood and metal.
On average, this type of screwdriver allows you to perform 1.25 - 1.50 more useful work without recharging than lithium-ion and combined ones.
But at the same time, cost, instability to extreme temperatures and relatively large sizes do not allow us to consider screwdrivers with this type of power supply as the only possible choice.
Popular models of INTERSKOL screwdrivers
To simplify the perception of information, popular models of INTERSKOL screwdrivers must be divided into two groups according to the type of battery - NiCd and Li-Ion, presented in the M1 and M3 series.
If we talk about the first group with nickel-cadmium batteries, then, of course, the most popular model is the compact DA-10/12M3, which, even with its modest price and dimensions, when fully charged, is capable of screwing about 400-450 standard screws into soft wood .
Independent tests confirm that this model, thanks to its unique structure and characteristics, is in many ways even superior to expensive foreign analogues.
There is also an even cheaper single-speed modification - DA-10/12M1.
It also differs in the absence of a spindle anti-locking mechanism and a double-clutch chuck.
The golden mean in terms of price and characteristics is the DA-10/14.4MZ and its variation with a flashlight – DA-10/14.4M3+F.
All other things being equal, a full charge will be enough for 500 or more self-tapping screws, which should be enough for a full working day.
Well, in conclusion, it’s worth talking about the most powerful model - DA-13/18MZ.
It’s a stretch to call it household, since regulatory loads quite allow it to be used in a construction organization.
The maximum diameter for drilling wood is 30mm, torque is 36 Nm, a powerful battery, and all this in a screwdriver that weighs only 1.8 kg.
More compact and lightweight devices with lithium-ion batteries in the L3 series are represented by only two models - DA-10/14.4 and DA-13/18, which are equipped with modern slider power supplies with the appropriate voltage (indicated in the name after the “/” sign).
The models have all the characteristic attributes of the third series of screwdrivers, namely a metal gearbox, rolling bearings, a robust housing and much more.
DA-12ER-02
Price: 3500 rubles
The product is equipped with additional lighting, so it can be used even in the dark, as well as in hard-to-reach, poorly lit areas. Like other Interskol products, this screwdriver has an electronic rotation speed control. The device's power button is locked to prevent it from being accidentally activated during transport or storage. The chuck is quick-release, which allows you to avoid wasting extra time changing bits and drills. The product kit already includes several nozzles with diameters up to 10 mm.
The owners note that using this battery model is very convenient due to the presence of two batteries at once. They are removable, the owner can change them as they are discharged. The mechanism also provides reverse, and the adjustable torque can reach 12 Nm. It's better not to buy a screwdriver for complex tasks, but it will do an excellent job of creating holes in wood and drywall.

In 2021, these brands include:
- Makita;
- RESANTA;
- Bort;
- Sturm!;
- BISON;
- PATRIOT;
- Kolner.
Also, brand popularity indicates the repairability of the tool, since the company can offer high-quality service and the parts necessary for repair or maintenance.

conclusions
When choosing a drill-driver from the Russian company Interskol, you need to take into account such nuances as:
- type of device - compact battery-powered devices and network models with an electric cable are available for sale;
- It is worth paying attention to the maximum torque, the presence of a two-speed gearbox and the safety system ;
- You should also consider the type and diameter of the chuck, the number of revolutions per minute of work, the diameter of drilling wood and metal .
Pros and cons of INTERSKOL screwdrivers
The undoubted advantages of INTERSKOL tools include:
• Wide selection of products at an affordable price. • Compact tools. • An extensive network of service centers where you can always repair screwdriver breakdowns under warranty. • An efficient dual-mode gearbox of a new generation that allows you to solve a wide range of drilling tasks and working with fasteners. • Variability of clutch settings, which allows you to adjust the force as accurately as possible. • All parts of the gearbox and spindle locking mechanism are made of good heat-resistant steel, which ensures a high level of reliability and durability of the tool. • There are no backlash bushings; the spindle shaft is supported using a system of two bearings. • Bright LED lighting. • There is no advantage in terms of engine power, battery capacity and tool size. The balance is perfectly calculated. • Automatic finishing and spindle locking. • Economical new generation Inter engines will ensure uninterrupted operation while charging batteries in a timely manner. • The embossed and impact-resistant case made of glass-filled polyamide will protect the product from damage when dropped, and will not allow this fall to occur due to increased friction between the hand and the rubberized handle.
This also includes resistance to high loads, the ability to drill metal even with non-professional screwdrivers.
And also standardized parts that are easy to replace.
INTERSKOL tools have virtually no disadvantages.
The only exception is that it has somewhat weak resistance to abnormal loads and temperatures, and also in some models there was a problem when the speeds switched independently when working with hard surfaces.
But this drawback was eliminated in the latest batches of screwdrivers produced.
Rating of the best models
Hammer DRL400A 280
Budget model of a non-impact corded screwdriver. This is one of the simplest tools that has only one mode of operation. The technical characteristics are also quite modest - torque 22 Nm, power 280 W. The disadvantages include slight play in the cartridge and rapid heating of the housing during operation.
However, this model has earned good reviews from its owners:
“Reliable model, good build. The cartridge is powerful and durable. Lightweight, convenient to use. Withstands loads on metal. Disadvantage: it heats up quickly under lateral loads; the gearbox has a soft shaft.”
“I bought a screwdriver for repairs. The tool has fully justified itself, it tightens well, and the torque adjustment is sensitive. A big plus is its compactness and lightness. The power cord is long enough. The gearbox is almost indestructible. The cartridge has a little play (axial play). If you use it for a long time, the case gets hot"
Drill-driver Interskol DSh-10/320E2
The screwdriver also belongs to the budget segment of tools, and has the following technical characteristics:
- Power – 320 W.
- Maximum torque – 35 Nm.
- 2 operating speeds.
- There is a power button lock.
The screwdriver is intended for household work, as confirmed by reviews from its owners:
“It works well for domestic conditions, the brushes are removable, the ratchet switch does not jam. The gears in the gearbox are made of metal, not plastic. The engine is powerful and massive, almost like a drill. But it heats up quickly, and the cord is short.”
“For drilling, a good speed is 1800 rpm. It also tightens quickly, no effort required. The disadvantages are that the cartridge is loose and sometimes does not clamp well. If you use it constantly, the gears of the gearbox wear down. So it’s not very suitable for heavy loads, but for repairs it’s just what you need.”
Makita DF0300
This tool has higher characteristics - power 380 W, and maximum torque - 56 Nm. There are 2 operating speeds - in screwdriver mode and drill mode. Quick-release chuck.
Additional options include:
- Lock the power button.
- Reverse rotation.
- Electronic speed control.
The tool is quite popular due to its characteristics and budget price.
“Assembled conscientiously, full price/quality ratio. Drills and tightens screws without any problems. Quite powerful and comfortable, reverse works great. I was pleased with the inclusion lock - the hand does not get tired of squeezing during long drilling. There is more than enough turnover. I personally didn’t find any drawbacks"
Hanskonner HID2145P
Hammerless drill/driver with power consumption of 450 W and torque of 35 Nm. There is a power lock button. The cartridge is metal, it is possible to replace the brushes without disassembling the housing. The model is equipped with a gearbox, which makes the rotation of the bit smooth. There is a reverse function. Among the shortcomings, users note the cartridge runout.
“The tool fits comfortably in the hand, the cable is quite long (4 meters), so there is no need for an extension cord. The wire is frost-resistant, so outdoor work can also be done. Assembly at a high level. The beating of the cartridge was disappointing - I expected better. Buttons and switches are a bit stiff"
Makita FS6300
A corded screwdriver designed for both domestic and professional use.
It has the following characteristics:
- Power consumption – 570 W.
- Maximum idle speed is 6000 rpm.
- There is a reverse motion.
- There is an electronic speed controller.
The screwdriver also has a magnetic clamp for bits, which allows them to be attached without a chuck. The spotlight allows you to use the tool in low-light areas and in the evening.
A fairly budget price and high performance characteristics have made the tool quite popular:
“Tightens screws quickly. Good power reserve, does not overheat. Convenient spotlight. Worked on drywall and installation of cabinet furniture. Everything is fine"
“Good price-quality ratio; I didn’t find any shortcomings during my work. The assembly is reliable and strong. The bit holder is also reliable"
Hitachi W6V4
This model is made in the form of a classic drill. The technical characteristics are quite serious - power consumption 620 W, maximum speed 4500 rpm. There is a magnetic bit holder, which eliminates possible problems with chuck runout. There is a power button lock. The tool is designed for high loads and professional use.
“Serious tool. Works well, the assembly is also of high quality. High number of revolutions. Fits well in the hand and does not slip. A little heavy, but that's normal for such an engine. The only downside is the price, but it’s completely worth it.”
AEG S 4000 E
The body of the tool also resembles a classic drill. Power consumption – 720 W, idle speed – 4000 rpm. There is a reverse stroke and a drilling depth limiter. This screwdriver also has a magnetic bit holder, which has a number of advantages compared to a classic chuck - there is no runout, the bits are securely and firmly fixed. Among the shortcomings, users note its narrow purpose - the tool is intended for construction work.
“Optimal size ratio, good mass centering. Convenient depth limiter. Not very suitable for drilling, despite the high speeds. The tool is highly professional and should be used for tightening screws."
BOSCH GSR 6-25 TE 2011 Case
Impactless professional screwdriver with power consumption of 701 W and torque of 20 Nm. There is a magnetic bit holder and reverse operation. The body is made in the form of a drill. The tool is quite large, but at the same time lightweight - weighs about 1.5 kg. This screwdriver can easily handle heavy loads, as it is designed for use in construction. Owners of the screwdriver note its good performance, ergonomics and ease of use.
“Comfortable to hold, not very heavy. Drills and tightens quickly and efficiently, the bolt goes into the wall like butter. Does not heat up during operation. The only “but” is that they are large, and the brushes need to be inspected often, because they can wear out with frequent use.”
“Professional and high-quality screwdriver. Used without problems, convenient to carry (case included). There is a belt clip for carrying. There is no play, the bits are securely fastened. Sometimes changing bits requires some effort, but overall I’m happy with the tool.”
Thus, in order to choose a truly high-quality screwdriver, you should first evaluate its technical parameters. Build quality and the name of the manufacturer are also important. But it is also necessary to focus on the scope of application of the tool - for everyday work a professional screwdriver is not necessary, but for work on a construction site, an ordinary, household tool is not suitable.
Which chuck for a corded screwdriver is better?
There are two main types of chucks: quick-release chucks and hex chucks with a magnetic holder - each of them has its own advantages and disadvantages, so you can definitely recommend any of them only if you know exactly where and how the screwdriver will be used.
Keyless chuck
Keyless chuck - bits are clamped with jaws, which are tightened with couplings on the threaded connection. This is the most common version of the chuck, installed on budget and professional tools. The two couplings can be conditionally divided into the upper one, which is located closer to the bit, and the lower one, near the screwdriver body.
To install the bit, you need to grab the lower clutch and start turning the upper one - the cams will separate, the bit is placed between them and clamped. Since the lower clutch is usually tightly connected to the motor (or gearbox) shaft, you can simply grab the upper clutch and press start - the cams will expand and contract if you turn on reverse.
Hex chuck with magnetic holder
A hex chuck with a magnetic holder is structurally simpler than a quick-release chuck - it has no moving parts. It is made for quick replacement of bits: there is no need to tighten anything - the bit is simply removed from the mount and another one is inserted in its place. In addition, it is easier to install a screw depth limiter on such a chuck, which comes as standard in many professional models of screwdrivers. The only negative is that the bit may “play” a little, because there is nothing rigidly holding it in the chuck.
For screwdrivers that can be used as a low-power drill, drills with a hexagonal shank are available - they have a cutout for a locking ring so that the drill does not remain in the board after drilling the hole.
If you have chosen a certain model of screwdriver, but it has a chuck installed that is not suitable for certain tasks, you can always buy adapters - they are low in cost and the quality of work will not suffer when using them.

DA-14.4ER
Price: 4600
Rechargeable device with two replaceable high-capacity batteries. The rotor does not break during operation, the device is light and compact. The handle and weight distribution are ergonomic, so your hand does not get tired even after long periods of work. The battery charges in just an hour and works even at low temperatures. There are additional functions: reverse, power lock, speed adjustment, flashlight.
Pros:
- light weight, only 1.2 kg;
- there is a flashlight, shock mode, reverse;
- electronic speed control in 18 positions;
- the range sparkled from 0.8 to 10 mm;
- There is a 3 year warranty from the manufacturer;
- high battery capacity, 1.5 Ah;
- Two batteries are included, and there is a case for easy transportation.
Minuses:
- a weak brush and cartridge cast doubt on the durability of the device;
- The same applies to the rubberized handle; after a month or two of use it will have to be changed.
Which body shape of a corded screwdriver is better?
When choosing a corded screwdriver, it is quite possible to make a model rating for yourself based only on the shape of the device. First of all, ease of use depends on it, and the body of the screwdriver will partially tell you about its internal filling and capabilities.
Pistol shaped
Most often this is a sign of a budget model, especially if the body is made entirely of plastic. If you disassemble such a screwdriver, you will find that the motor shaft is directly attached to the chuck. Those. the quality of work directly depends on the power of the engine and the smoothness of its operation. Often, owners of such devices complain about the rapid heating of the case during operation, but for periodic short-term household work, such a screwdriver is quite suitable. This form of the device allows you to press in the screw while tightening, which will inevitably have to be done due to the low engine power.
T-shaped body
In general, this is the same device as in the form of a pistol, but the handle is shifted to the center of the body - it is generally believed that this strains the hand less when working. Here we must take into account that all devices have different electric motors, each with its own mass, alignment and other characteristics. It is difficult to judge how convenient this or that model will be without holding it in your hands.
Classic drill body
This is already a sign of the class of professional devices, since the characteristic “belly” indicates the transmission of force to the cartridge through a gearbox. This means that the bit rotates more smoothly, and it is easier to regulate the number of revolutions per minute. It’s also very convenient to support the screwdriver by the “belly” with the second hand (if there is no additional handle) - during prolonged work this will have to be done, because the weight of such devices is about 1.5-2 kg.
