How to choose the best corded screwdriver? Which corded screwdriver is better to choose for professional and household use? Which corded screwdriver is better for the home.
From time to time in the household there is a need to drill a hole, tighten up loose furniture, or mix glue or mortar. To do this, do not purchase three tools: a drill, a screwdriver, and a hammer drill. Buy one corded screwdriver with a drill function, and all problems will be solved quickly and efficiently. Such a tool, unlike a battery-powered one, has more power, better performance, and works for a long time without requiring recharging.
How does a corded screwdriver work?
Power tools of various brands and manufacturers are endowed with many technical characteristics, functions, and housings that are different from each other. However, their design and basic operating principle are almost the same. The only difference is small nuances. The photo shows how corded screwdrivers look from the inside:
It bears the following symbols:
- Start button.
- Reverse switch.
- Capacitor.
- Electric motor.
- Frame
- Gearbox
- Cartridge.
The screwdriver is powered by a 220 volt network and is equipped with a motor DC. The reverse button changes the polarity of the power supply, as a result the motor rotates in the opposite direction and the device turns out the screws instead of screwing them in. Gearbox parts are made of metal or technical plastic. An electric screwdriver acquires additional operational functions when equipped with a two-speed gearbox. A speed of 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, and 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 disadvantages. The equipment is not cheap, especially when it comes to branded models. Therefore, make your choice of a corded screwdriver after thoroughly familiarizing yourself with the item you like.
- Corded screwdrivers are lighter in weight and smaller in size than cordless screwdrivers. Because the battery inserted into or attached to the body makes the tool heavier and increases its weight.
- A 220V screwdriver does not lose power during operation, while a battery-powered tool gradually loses it in parallel with the decrease in battery charge.
- Depending on the power supply conditions and the characteristics of some brands of batteries, it may happen that while charging them, you have to stop all other work. A powered drill/driver will not allow this situation to happen.
- Price also matters. The best corded screwdriver costs much less than its cordless counterpart.
What to look for when buying a tool
When you stop in front of a shop window or look through a catalog, it is clear that it is impossible to immediately fix your gaze on a decent device. First, you need to know exactly two things: why we are buying and how much we can expect. Since you can choose a corded screwdriver of decent quality only by knowing its long-term tasks in advance. At the same time, it is good to understand what important parameters you should pay attention to. Of these we denote:
- Power. The weight of an electric drill-driver and its productivity depend on this indicator. For home use, a power of 450-650 W is sufficient; professionals need a more powerful tool.
- Torque. Characterizes the force with which the device is capable of working. This value affects the choice of material and the size of fastening devices with which the tool can work. For household work, a torque of 25-30 N*m is sufficient.
- Reverse. Its presence is mandatory when a networked home screwdriver is needed not only for tightening fasteners, but also for removing them.
- Rotation speed and mechanism for its regulation. Changing the indicator makes it possible to use the tool in different conditions.
- Comfort during operation. This includes light weight, comfortable grip of the handle, cord length and other properties that allow you to create best conditions at the workplace.
The main thing is not to confuse a screwdriver with a drill. It is believed that if the device has a battery, it means a screwdriver, and if there is a plug, then it means a drill. This is not an argument. The main difference is constructive solution. When the start button is pressed, the screwdriver chuck stops instantly. While the drill continues to spin for some time. That is, its mechanism does not have a run-out brake. But now you don't need to buy these two tools separately. You can choose an electric screwdriver/drill, which has universal functionality.
Rating of networked screwdrivers
Professional models are unlikely to be needed at home. They are expensive and massive. To replenish your home arsenal, low- or medium-power tools are quite suitable. See the rating of network screwdrivers in the table, and below we will introduce you to the most popular household models.

This article introduced important aspects selection of an electric screwdriver powered by a 220-volt network, with three popular models. It’s up to you to decide which tool to buy, corded or battery-powered. Depending on the volume of work to be done, on trust in a particular brand. From this video you will learn about other brands of Russian cars that are not included in the rating.
When choosing the right screwdriver for a particular task, you should pay attention to various characteristics. Among them, the most important are not only the power of the device and the capacity of its battery, but also the battery voltage, and even the torque value.
During construction and repair work a screwdriver is an indispensable tool that simplifies tightening various types fasteners, and sometimes even drilling holes. And, despite the fact that there are two versions of this device - mains and battery-powered, more often the latter option is chosen to perform household tasks. At the same time, attention is paid to the parameters of the power tool itself and to such characteristics as the voltage in the screwdriver, its power, torque and battery capacity. Each of these indicators is important for evaluating and choosing the correct device. Whereas it’s not worth buying based on suitable power or voltage alone.
Basic parameters of the battery and the tool itself
The main parameter that characterizes the operation of a screwdriver is the battery voltage, which, in turn, determines the power of the electric motor and torque. For household models, the difference in voltage between screwdrivers is small - on average, it is in the range of 10.8–14.4 V. More productive options, intended for constant use, can be equipped with 24–36 volt batteries.
The battery voltage of a screwdriver also depends on the type of battery - you can answer what the difference is by knowing what metals were used to make it. For nickel-cadmium batteries, large in size with a similar capacity, the value of the indicator is a multiple of 1.2 V (this is the voltage of one element that makes up the battery pack), for lithium-ion batteries - 3.6 V.
Other equally important characteristics include:
- the power of the screwdriver, which can also be used to determine the speed of tightening screws and self-tapping screws. To carry out repairs on your own, models with a performance of 500–700 W are sufficient. A professional repairman will need more powerful equipment - 800–850 W;
- the number of revolutions of the rotating part of the device per unit time. This parameter determines whether the screwdriver can perform the task assigned to it - for example, tighten the required type of fastener. So, for a bolt, self-tapping screw and screw, 500 rpm is enough, for drilling you will need 1200 rpm;
- torque, the value of which can be one of the main answers to the question of what the voltage of the screwdriver battery affects. Using this characteristic, you can determine both the diameter and the length of the screw or self-tapping screw being screwed. Large fasteners, as well as drilling deep and wide holes and hard materials, require significant torque. The maximum value of the indicator is 10–60 Nm.
There are two types of torque for screwdrivers - starting (larger in magnitude and required to start the device into operation) and constant, that is, working. Parameter value y modern models equipment can be adjusted - you can find out how many modes can be selected for a particular device in the documentation available for it. Moreover, tools with a pulse mode of operation (turning on the rotating part in jerks) have more screwing capabilities - allowing them to periodically increase the torque, they can screw in a larger screw.
The output torque value of electric motors is not constant and depends, first of all, on the speed of the motor; the higher the speed, the lower the torque on the shaft.
In addition to the voltage of the screwdriver and its power, the battery capacity should also be assessed. The characteristic is measured in ampere-hours or milliamp-hours. The higher the indicator, the longer the screwdriver can work without recharging.
The average battery capacity of a household model is 1300 mAh, which is enough for 2–3 hours of operation. Professional equipment requires more time to complete the work - and a master who uses a screwdriver throughout the whole working day should purchase a model with 1.5–2.0 Ah batteries.
Features of choice
When choosing power, you should take into account not only what power of the screwdriver is indicated in the information from the manufacturer. Due to too much productivity, the device may tighten the screws too tightly, pressing their heads into the surface. As a result appearance the coating deteriorates, and the fasteners, if necessary, are almost impossible to unscrew. 
When choosing which voltage is best for a screwdriver, you should take into account that voltage is the main parameter of the device. For example, the motor power of the Makita DDF343SHE screwdriver is 700 W, with a voltage of 14.4 V and a battery capacity of 1300 mAh and a torque of 36 Nm. Whereas another model Hammer ACD182 has more weak engine(22 Nm) and a not so capacious battery (1200 mAh) - and it seems that this device is about 40% weaker. However, due to the 18 V voltage, the Hummer is able to tighten more fasteners without recharging, even being inferior to its competitor in terms of battery capacity.
You can understand why a screwdriver that seems less productive at first glance is inferior to a more powerful one by doing a little calculation:
- the amount of energy stored by the first model is 1.2 x 1.8 = 21.6 Wh;
- the second indicator is only 1.3 x 14.4 = 18.72 Wh, i.e. 15.4% less.
When choosing a screwdriver, it is advisable to take into account the presence of a spare battery included with it. Some models even have 2 additional batteries. On the one hand, such equipment will cost more (especially since the cost of the battery is up to 80% of the price of the equipment), but it will be much more convenient to work with it. At the same time, an additional battery is not needed to perform household tasks - the time of work performed with its help rarely exceeds 1–2 hours. Whereas during constant use of a screwdriver (for example, for repair work or furniture assembly), the second battery allows you to not interrupt work for more than a few minutes. The discharged battery is charged, and a spare battery is installed in the device.
If there is no need for long-term work, which may require a screwdriver, it is not recommended to buy a model with additional batteries, not only because of its increased cost. It’s just that the service life of such a battery is short, and after a couple of years the user will have to buy new part, without using up even half the resource of the old one.
Summing up
To summarize the article, it is worth noting that the battery power of a screwdriver, although it is an important parameter when choosing suitable model, voltage and capacity indicators are much more important. And most often it is worth paying attention to torque only if it will be used to not only screw in, but also drill. You should also know that maximum power cordless screwdriver of all commercially available models with a device with a voltage of 36 V, a torque of 60 Nm and a capacity of 3000 mAh. Such equipment is quite difficult and not very convenient to use without professional experience. This means that you should opt for less productive options produced by well-known and reliable brands such as Bosch, Hitachi, Makita, AEG, Dewalt and Metabo.

Are you interested in a specific model and would like to know more about it? Be sure to read a more detailed review of the device you like to know about all the possibilities.
If you take into account screwdrivers that can operate on mains power and compare them with models with a battery power supply, then mains-powered tools may turn out to be more productive, allowing for continuous work. Choosing a corded screwdriver is a responsible matter, so in order not to make a mistake in choosing the right tool, use the material that we have prepared for you.
When choosing a corded screwdriver, you should carefully evaluate its operational 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 quite enough.
- Torque parameter. The indicator serves as a direct guide to the performance of the tool, characterizing its possible force when the bit is working. In addition, the amount of torque indicates the possible material 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 allows the tool to be used as a “retriever” 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 the listed 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 self-tapping screws. The most critical operations are best performed using a unit whose base power exceeds 650 W. Here it is already appropriate to talk about the professional category, where you can often find modifications with a power of up to 850 W.
Which screwdriver is better - electric or cordless? The answer to this question depends on the goals that the master sets for himself - if the working conditions do not require the presence electrical network, then the battery unit will be better; If the power of the device is important in your work, a network-powered unit will always give a head start to a battery-powered one.
What types of corded screwdrivers are relevant? + (Video)
First of all, the difference between network units is due to the typical design of the cartridge and the mechanism for holding the bit.
- The tool chuck may have a toothed structure, which in the form of a nozzle is fixed to the device mounts using a key. It is noteworthy that although this process requires spending some time and effort, this particular fastening option is characterized by absolute reliability.
- A tool equipped with a quick-release chuck is quite convenient to use, since the mechanism itself is quite lightweight. The nozzle can be changed as quickly as possible. However, if you have to work with hard 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. Consequently, the choice of attachment power for the corresponding tool will also be classified. If this is a non-professional tool, then the standard is a cartridge with a diameter of 0-20 mm.
Regarding the presence on board of the device of a functional feature in the form of a drill, 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);
- from 400 to 1300 revolutions (using drilling mode).
An important criterion for a modern screwdriver is the type of motor, which can be equipped with brushes or without them. The second option is more expensive. The engine runs with less noise, starts smoothly and is not demanding 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 include an additional set of brushes.
What models of corded screwdrivers deserve attention? + (Video)
Choosing the best corded screwdriver. To choose a high-quality and inexpensive network unit for home use or professional needs, take a closer look at our small rating of power tools that deserve attention.
- Interskol DSh-10. A relatively inexpensive screwdriver equipped with a 260-watt motor with a shockless 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 motor, the torque of which is guaranteed maximum value 25 N*m. As an additional functionality, there is a two-position speed control.

What rules for using a corded screwdriver should you follow?
An electric screwdriver requires the owner to have 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 a networked version of a 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 interaction with moisture. There is a likely risk of a short circuit or damage to individual modules of the device, leading to the failure of the instrument.
- Observe proper safety precautions, for example, when changing attachments. Make sure the tool is de-energized before changing attachments. There is a risk of hand injury. In addition, with a high degree of probability, the fastening mechanism itself can be damaged.
- The operating mode of the tool should be selected based on the required tasks. Required before new job check necessary settings rpm and corresponding power.
- And, of course, no matter which unit you choose, make sure that it does not have damaged wires, dangerous kinks or bends.
We hope that the article was useful to you and you were able to learn how to choose a corded screwdriver, which corded screwdriver is considered the best and how to use the corded tool correctly.
