Drill-screwdriver network: a universal device for screwing and drilling
A power drill is an electric tool used by home craftsmen for various kinds of work. Such a device combines the functions of a screwdriver and a drill, and can also be used for mixing liquid building compounds, which allows a special nozzle. To choose an effective and reliable device, it is necessary to study the features and principle of operation of screwdrivers operating from the electrical network.
Features of the electric drill-screwdriver device
Devices that work from the electrical network are incredibly in demand. The demand for such devices is explained by their irreplaceability and universal qualities. They can be used for completely different tasks. They operate from the power grid, the voltage in which is 220 V.
Useful information! Network (or, as they are also called, wired devices) have a characteristic appearance. They include an oblong body and a handle responsible for the convenience of using the device. The handle has a special “Start” button, through which the device is started.
From the bottom of the handle of the wired screwdriver comes an electric cord that is plugged into an outlet while using the device. Such devices have one feature: they are equipped with a special magnetic holder included in the gearbox design.
Such a tool also includes a number of other components. The electric motor provides the rotation of the device necessary for operation. A special limiter located in the working part is designed to regulate the depth of screwing.
The main components include the electronic unit responsible for controlling the device and the clamping chuck. Electric screwdrivers of this type include a half coupling, which has one feature. This part is able to reset the torque force of the holder. This happens when the maximum screwing depth is reached. Some devices belonging to the middle and higher price categories may have a speed shifter. The performance characteristics of such devices are much higher, so they are recommended by specialists.
Varieties of electric screwdrivers depending on the shape of the case
According to this indicator, there are two types of devices. The convenience of using the device depends on the form, so you should definitely familiarize yourself with its main options. So, today you can find the following models of screwdrivers on sale:
- in the shape of the letter “T”.
Devices that belong to the first type are more budget-friendly. The housing of such devices is made of plastic. In network drills, the chuck is fixed directly to the motor shaft, so the quality and efficiency of the device depend on how much power it has.
Pay attention! The main disadvantage of pistol devices is the rapid heating of the case during operation. This suggests that they cannot be used for a long time.
In turn, the devices, the body of which has the shape of the letter “T”, differ from the pistol by the location of the handle. In such models, it is shifted to the center. Electric drills-screwdrivers of this type can be purchased for a higher cost. It is believed that the T-shaped housing minimizes the stress exerted on the hand during operation of the device.
Most often, the models belonging to the second group are professional and are used by qualified workers. The electric motor of such devices rotates the bit more smoothly, which increases the efficiency of the device. The rotation speed in such screwdrivers is regulated by a special part – a planetary gearbox.
Classification of electric network screwdrivers by operational area
This versatile and compact device can also be classified depending on the field of use. Let’s consider two options for wired screwdrivers, which can be easily purchased in a specialized store or ordered from an online store:
Household appliances are bought for private use at home. Such models, as a rule, differ in a democratic cost and are quite simple. There are practically no additional functions in this case, since the products must perform simple work with long time intervals between it.
Manual electric drills-screwdrivers of household type are characterized by a small engine power. Experts categorically do not recommend subjecting such a device to prolonged use. Despite all the disadvantages of the device, its cost fully corresponds to the functionality. If you follow the operating rules, then such a device will last quite a long time.
Professional models are used by craftsmen in various areas of the construction industry. With their help, work is performed that requires high power. Such devices are resistant to overheating. Another advantage of such models is their long service life, but professional screwdrivers need special care.
To choose a model suitable for use in specific conditions, it is recommended to study the characteristics of individual screwdrivers. Reviews left on specialized forums also contribute to the acquisition of a reliable device.
There are also special compact devices that have minimal power. It is enough to perform simple operations. They can be used both in the household and in the professional construction field.
Drill-screwdriver network: advantages and disadvantages
Electronic devices of this type, functioning from the network, have a number of advantages, due to which they have become widespread in the construction sector. Let’s consider the positive characteristics of such devices in more detail.
Useful information! The main advantage of such devices is the absence of a rechargeable battery. Of course, the models that have it are more mobile, but they are not designed for long-term operation. The availability of uninterruptible power supply allows you to perform large amounts of work at high power.
Electric drills-screwdrivers are also more convenient to use, since they have a smaller mass. This is due to the lack of a rechargeable battery. Due to the ability to perform work at high speeds, significant time savings occur. All operations are performed several times faster.
Another positive point, which is very important for those who use screwdrivers not only at home, but also on the street, is the resistance of the wired device to weather conditions. At low temperatures, devices that are not connected to the mains lose charge much faster, which leads to the need for constant battery change. The price of electric drills, characterized by frost resistance, is higher than the cost of standard analogues.
Disadvantages of wired screwdrivers are also present. The most significant disadvantage is the limited range of action, which completely depends on the length of the electric cord.
Electric drills-screwdrivers: types of devices according to the principle of operation
All such devices can be divided into groups according to the principle of action. The operational affiliation of these devices depends on the features that manifest themselves during operation. Quite popular are models with an engine brake. The brake functions by closing the motor. In order to stop the device, simply release the “Start” key. On sale you can also find devices that have a mechanical brake.
Another modification of the wired device is shock. An electric drill of this type creates impulses that contribute to screwing in a metal product. At the same time, the engine of the device begins to rotate in jerks, which are characterized by high power. This allows you to perform even the most difficult work.
There are highly specialized models used for drywall. A special restrictive coupling is included in their design. With its help, the depth of screwing in screws, which have a sufficiently large length, is adjusted.
Types of cartridges: choosing the best drill-screwdriver
Network models differ from each other in one more indicator – the structure of the cartridge. The design features of this part determine how reliable the device will be during use. Let’s consider which devices are most often found on sale today.
Models equipped with toothed cartridges have become widespread. In such devices, the nozzle is attached by using a special key. The time spent on this procedure is the main disadvantage of such devices. However, they are highly reliable, which is why they are so popular. The price of network screwdrivers of this type is quite democratic.
The next subspecies are screwdrivers, which have quick-release cartridges. The replacement rate of the tips in this case is significantly higher than that of other devices. It is recommended to purchase such devices to perform simple work. This is due to the fact that the reliability of fixing the nozzle in this case is much lower.
Pay attention! Devices with quick-release cartridges are not suitable for screwing metal products into surfaces characterized by increased hardness.
The most effective, allowing you to perform complex tasks are impact drills-screwdrivers. Network devices of this type are more expensive than standard ones, but their price fully corresponds to the operational characteristics. The power of the nozzle depends primarily on the diameter of the cartridge. Devices intended for domestic use have a cross-section not exceeding 20 mm.
How to choose a screwdriver drill: main features
When choosing an electric tool used for drilling, it is necessary to pay attention to several of the most important characteristics that determine its operational suitability. Consider the key indicators of network devices.
Power. When choosing a tool for drilling and screwing metal products, it is necessary first of all to take into account what power it has. This indicator affects the functionality of the device. As a rule, budget options have little power, but you can also find good inexpensive screwdrivers.
The power range can vary from 100 to 900 watts. For domestic use, it is recommended to purchase models in which this indicator is approximately 400-500 watts. The amount of electricity that the device will consume during operation depends on the power of the device.
The torque. This parameter determines the force that will be applied to the metal product and the drill itself during rotation. Knowing this value, you can determine which material a particular tool is suitable for. It is measured in Newtons per meter (N/m).
For devices that will be used for economic purposes, 10 N/m is enough. Professional devices should have a stronger torque – at least 30 N/m. The most reliable models with high efficiency are the German Bosch screwdrivers, which combine quality and stylish design.
Battery grinder: necessary information about the tool
Characteristics of different types of circles. Which disk to choose for metal, wood and stone processing. Dimensions and marking of circles.
The speed of rotation. This parameter is optional if you need to choose a household model. But in the construction industry, the speed of rotation is very important, since drilling accuracy and the speed of work depends on it. Network impact screwdrivers are the most efficient and have a high speed of revolutions.
Reverse. For network devices, the presence of this function is a mandatory rule. The convenience of using the screwdriver depends on exactly where the switch is located on the device body. Most often, the switch is placed in close proximity to the “Start” button.
The speed switch. This function is important only if the device will be used not only for screwing in metal products, but also for drilling holes. The switch is located on the body of an electrical wiring device.
Before choosing a specific device, it is recommended to study the rating of network screwdrivers. It presents the tools most suitable for domestic as well as professional use.
Pay attention! In order to screw in a metal product, a speed of 500 rpm is enough. In turn, for drilling, it must be higher. To make an accurate hole, a minimum value of at least 1500 rpm is required.
Additional functions of network screwdrivers
Before purchasing a specific model of the device, it is also recommended to evaluate its additional functions. Some of them are very useful in domestic use. It is much easier to perform diverse work with a device that has a speed controller. With its help, you can control the speed of drilling and screwing, which allows you to effectively work on surfaces with different densities.
The best network screwdrivers include the option of adjusting the speed of the working tool. The cost of such devices is higher, but if necessary, you can choose a fairly budget model. It is also worth paying attention to devices in which the possibility of fixing the “Start” key is implemented. This function is most often found in professional tools. Such devices are charged with screws and are called tape. Their design includes a special coupling, which, when in contact with the screw, begins to unwind the cartridge with the bat.
For household appliances, the presence of a lock is not so important. This function may be needed only if the screwdriver has a high power, which is sufficient for drilling holes in high-density materials. In other situations, its presence is not so important, therefore, for economic purposes, it is recommended to purchase models with a lower price. Electric screwdrivers can also be equipped with special lighting. This is convenient if the work is done in a room that does not have sufficient lighting.
Some modifications of screwdrivers contain special compartments on the body, which are necessary for storing additional bits. Modern models are equipped with locking devices for fixing the device on the mounting belt. All of the above functions can be useful depending on the nature of the work, so you should decide in advance on the operational purpose of the device in order to purchase a model that does not include anything superfluous.
Which network screwdriver is better to buy: cartridges and gearboxes
Cartridges, which are also called spindles, are installed on network screwdrivers and can be of several types depending on the design features. The first variant of such a part is a three–cam key. Such cartridges are classic and are installed on drills. They are characterized by a high degree of reliability when fixing the drill. In the ratings of network screwdrivers, this variety is quite common.
Pay attention! Three-cam key elements are capable of centering accurately enough. It should also be said that their clamping force is higher than in devices equipped with other types of cartridges.
The second type of cartridges is keyless, which is considered less reliable. However, manually fixed products are more appropriate to use if the tips need to be changed frequently during operation. An example is the Vortex device. A drill-screwdriver of this type has an acceptable cost.
Quick-release cartridges mounted on screwdrivers are less reliable, but they are great for home use. Professionals also actively use devices of this type, because they significantly increase the speed of the work performed.
Gearboxes include polymer materials. This significantly reduces their reliability. Of course, the price of a drill-screwdriver of this type will be lower, but it is impractical to buy it for active use. Plastic parts are more susceptible to wear and have a relatively short service life. The presence of a plastic gearbox is permissible only in those models that are purchased for infrequent household use.
Network screwdriver Sturm ID2145P: the best value for money
This device is manufactured by a German company, whose products are of high quality components. The device of this series belongs to the budget range, so anyone can buy it. For domestic use, it is suitable as well as possible.

The length of the network cable of the Sturm screwdriver of this series is 4 m. This allows the work to be carried out without the use of extension elements. The gearbox in this device is made of metal, which is also a serious advantage that prolongs the operational life of the product.
Network screwdriver Zubr ZSSH-300-2: the best combination of cost and power
This is a domestic device that has a good power (300 watts). The length of the cable in this case is a significant advantage. The device has a five-meter cord, which allows you to perform work at a considerable distance from the outlet. The motor of the device provides high torque when drilling and screwing, namely 35 N/m.
Useful information! The cable of the device is covered with a layer of special frost-resistant rubber, which allows the device to be used outdoors in the winter season.
The maximum idle speed can reach 1400 rpm. The screwdriver of this series has two speed modes, which increases the scope of its application. Many users choose just such a model for home use.
The device has the possibility of reverse rotation. The Zubr network screwdriver is able to adjust the rotation speed, which happens thanks to an electronic control system. The cartridge cross-section indicator in this case is standard and is 10 mm. The quick-release tool increases the convenience of operation with frequent change of tips.
The purchase of such a model allows for high operational safety, since it has a system that blocks the “Start” key. It is also worth highlighting that the device has a small weight, and its warranty period is 5 years.
Network drill-screwdriver Interskol DSH-10/320E2: a convenient device for the home
Products of this series are manufactured by a domestic manufacturer. The Interskol device has a high torque, despite the fact that it consumes a minimum of power. Thus, it can be classified as an economical device. This device implements the function of an impact-free drill, which allows you to use a screwdriver to drill holes in hard surfaces.
The characteristics of such a device determine its reliability. Such screwdrivers are often found in small workshops. The material from which the gearbox is made is plastic. However, the working elements in it are made of metal, so the tool is resistant to wear.
The Interskol network screwdriver of this series includes an average power motor, namely 320 watts. The torque of such a device is quite high and is 35 N / m. This is more than enough to screw in quite large metal products. The maximum diameter of the screws that such a device can screw is 6-7 mm.
The quick-release cartridge simplifies the operation of the device. The diameter of this part is, as in previous models, standard 10 mm. Such a screwdriver can also function in two speed modes. The first of them is recommended for screwing, and the second for organizing holes in surfaces of different densities. This model is quite common in various ratings of network drills-screwdrivers.
The length of the network cable of such a device is not the largest – only 2 m, but it is quite enough for domestic use. It should be remembered that an extension cord may be needed to operate the Interskol model. Additional functions of this device include reverse rotation and the ability to lock the “Start” key.

If we take into account all the characteristics of such a device, it is worth noting that it resembles the previous device of the company “Makita”. Bosch electric drill-screwdriver has some disadvantages. The main disadvantage of the device is its large mass. It is also worth saying that the process of changing the tips is quite time-consuming. The rest of the reviews about this device are mostly positive.
Safety precautions when working with a network screwdriver
Working with a tool that operates from the power grid requires the master to comply with a number of rules. Before activating the device, it is necessary to inspect it. If a defect is detected, it is not recommended to turn on the device. The same applies to the network cable, which is very easy to damage, especially if the house is being repaired.
Pay attention! If the device is not activated, then most likely the problem is related to its internal parts. For self-repair of the device, it is worth studying the electrical diagram of the drill. Otherwise, it will be much more difficult to identify the malfunction.
The change of the nozzle should be made based on the type of cartridge. For example, gear types require a special key, so it is strongly not recommended to perform this operation without it. Failure to comply with this rule may lead to tool failure.
After replacing the nozzle, it is worth checking it. The tip must be fixed firmly. During the operation of the drill, in no case should you touch its movable elements. Many people are interested in the question of how to make a network screwdriver from a screwdriver. It is dangerous to do such work independently, but when studying an electronic circuit and observing all the necessary rules, it is possible. After using the device, it must be switched off.
Thus, wire screwdrivers are indispensable tools that are used both for household and professional purposes. When choosing a specific model, it is necessary to pay attention to its power and weight. The device should be convenient to use, so its shape should also be taken into account. Changing the working nozzles for a home tool is not so important, but if you plan to actively use it, it is better to purchase a quick-release version.
