Power drill / driver: universal device for screwing in and drilling

The cordless drill is an electric tool used by DIYers for all sorts of work. Such a device combines the functions of a screwdriver and a drill, and can also be used to mix liquid building compounds, which allows for 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 an electrical network.

Drill driver - a versatile tool that will come in handy in every home

Features of the electric drill-driver device

Gadgets that are powered by an electrical network are incredibly popular. The demand for such devices is due to their indispensability and universal qualities. They can be used for completely different tasks. They operate on an electrical network with a voltage of 220 V.

Electric drill / screwdriver has advantages and disadvantages

Helpful information! Network (or, as they are also called, wired devices) have a characteristic appearance. They include an elongated body and a handle for ease of use. The handle has a special "Start" button, through which the device is started.

From the bottom of the handle of the cordless screwdriver, an electrical cord comes out that is connected to the outlet during use of the device. Such devices have one feature: they are equipped with a special magnetic holder included in the design of the gearbox.

Such a tool also includes a variety of other components. The electric motor provides the rotation of the device necessary for operation. A special stop located in the working part is designed to regulate the screwing depth.

The main components include the electronic unit, which is responsible for controlling the device, and the chuck. Electric screwdrivers of this type include a half-coupling, which has one feature. This part is capable of dumping the torque force of the holder. This occurs when the maximum screw-in depth has been reached. Some devices belonging to the middle and higher price categories may have a speed control knob. The performance characteristics of such devices are much higher, therefore they are recommended by experts.

The tool consists of an electric motor, block, chuck, cord and other parts

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 on sale you can find the following models of screwdrivers:

• pistol;
• in the shape of the letter "T".

The devices of the first type are more budgetary. The body 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 depends on how much power it has.

Note! The main disadvantage of pistol devices is the rapid heating of the body during operation. This suggests that they cannot be used for a long time.

In turn, devices, the body of which has the shape of the letter "T", differ from pistol-type devices in the location of the handle. In such models, it is shifted to the center. Electric drills of this type can be purchased for a higher cost. The T-shaped body is believed to minimize stress on the hand during operation.

Devices in shape are of two types: T-shaped and pistol

Most often, 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 speed of rotation in such screwdrivers is regulated by a special part - a planetary gear.

Classification of electrical network screwdrivers by operational area

This versatile and compact device can also be classified according to the application. Consider two options for wired screwdrivers, which can be easily purchased in a specialized store or ordered from an online store:

• household;
• professional.

Household appliances are bought for private use at home. Such models, as a rule, have a democratic cost and are quite simple. In this case, there are practically no additional functions, since the products must perform simple work with large time intervals between them.

Hand-held electric drills and screwdrivers of household type have a low engine power. Experts categorically do not recommend subjecting such a device to prolonged use. Despite all the disadvantages of the device, its cost is fully consistent with the functionality. If you follow the operating rules, then such a device will last quite a long time.

Drill drivers are classified into professional and household

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, however, professional screwdrivers need special care.

In order to select the model suitable for use in a specific environment, it is recommended to study the characteristics of individual drills.The reviews left on the specialized forums also contribute to the acquisition of a reliable device.

There are also special compact devices that have a minimum power. It is enough to perform simple operations. They can be used both in the household and in the professional construction industry.

Power drill-driver: advantages and disadvantages

Electronic devices of this type, operating from the network, have a number of advantages, due to which they are widely used in the construction industry. Let's consider the positive characteristics of such devices in more detail.

Electric drill / screwdrivers have many advantages

Helpful information! The main advantage of such devices is the absence of a rechargeable battery. Of course, models that have it are more mobile, but they are not designed for long-term operation. The presence of an uninterruptible power supply allows you to perform large volumes of work at high power.

Electric drills are also more convenient to use as they are lighter. This is due to the lack of a rechargeable battery. Thanks to the ability to perform work at high speeds, significant time savings are achieved. 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 outdoors, is the resistance of the wired device to weather conditions. At low temperatures, devices that are not connected to the network lose their charge much faster, which leads to the need to constantly change the batteries. The price of electric drills with frost resistance is higher than the cost of standard counterparts.

Network devices are lighter than battery-powered devices

There are also disadvantages to corded screwdrivers. The most significant disadvantage is the limited range, which depends entirely on the length of the power 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 accessibility of these devices depends on the features that appear during operation. Models with a motor brake are quite popular. The brake functions by closing the motor. In order to stop the device, simply release the “Start” button. On sale you can also find devices that have a mechanical brake.

Another modification of the wired device is the shock one. An electric drill of this type creates impulses that help screw in the metal product. In this case, the engine of the device begins to rotate in jerks, which are characterized by high power. This allows even the most difficult work to be done.

There are highly specialized models used for drywall. A special limiting clutch is included in their design. With its help, the adjustment of the screw-in depth of screws, which have a sufficiently large length, is carried out.

The most popular drills are shock and brake motor

Chuck types: 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. Consider what devices are most often found on sale today.

Models equipped with gear chucks are widely used. In such devices, the nozzle is attached 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 this type of network screwdrivers is quite affordable.

The next subspecies are screwdrivers that have keyless chucks. The speed of tip replacement in this case is much higher than that of other devices. It is recommended to purchase such devices for performing simple work. This is due to the fact that the reliability of fixing the nozzle in this case is much lower.

Note! For screwing metal products into surfaces characterized by increased hardness, devices with keyless chucks are not suitable.

The most demanded chucks are considered quick-release and toothed

Impact drills are the most effective, allowing you to perform complex tasks. 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 chuck. Devices for domestic use have a cross-section not exceeding 20 mm.

How to choose a drill-driver: basic characteristics

When choosing an electric tool used for drilling, it is necessary to pay attention to several of the most important characteristics that determine its usefulness. Consider the key metrics of networking devices.

Power. When choosing a tool for drilling and screwing in metal products, you must first 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 find good inexpensive screwdrivers as well.

The power range can vary from 100 to 900 watts. For domestic use, it is recommended to purchase models for which this figure is approximately 400-500 watts. The amount of electricity that the device will consume during operation depends on the power of the device.

If the device is purchased for domestic use, then it is recommended to buy models with a power of 400-500 W

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 for which material a particular tool is suitable. Measured in newtons per meter (N / m).

For devices that will be used for economic purposes, 10 N / m is sufficient. Professional devices must have a higher torque - at least 30 N / m. The most reliable models with high efficiency are the German Bosch screwdrivers, which combine quality and stylish design.

Rotational speed. This parameter is optional if you want to select a household model. But in the construction industry, the speed of rotation is very important, since the accuracy of drilling and the speed of work depends on it. Cordless impact screwdrivers are the most efficient and have a high RPM.

Reverse. For network devices, this feature is a must. The ease of use of the screwdriver depends on where exactly the switch is located on the body of the device. Most often, the switch is located in the immediate vicinity of the Start button.

When buying, you need to pay attention to the rotation speed and torque

Speed ​​shifter. 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 the electrical wiring device.

Before choosing a specific fixture, it is recommended to study the rating of corded screwdrivers. It presents the tools most suitable for household as well as professional use.

Note! In order to screw in a metal product, a speed of 500 rpm is sufficient. In turn, it must be higher for drilling. To make an accurate hole, a minimum value of at least 1500 rpm is required.

Additional functions of network screwdrivers

It is also recommended to evaluate its additional functions before purchasing a specific instrument model. Some of them are very useful in the home environment. 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 in, which allows you to effectively work on surfaces with different densities.

Some models of network devices are equipped with a speed controller

The best corded screwdrivers include the option of regulating 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 realized. This function is most often found in professional tools. Such devices are charged with screws and are called tape devices. Their design includes a special coupling, which, upon contact with the screw, begins to spin the cartridge with the bat.

For household appliances, the presence of a retainer is not so important. This function may be needed only if the screwdriver has a high power, which is sufficient for drilling holes in materials with high density. In other situations, its presence is not so important, therefore, for economic purposes, it is recommended to purchase models that have 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 case, which are necessary for storing additional bits. Modern models are equipped with fixing devices for fixing the device to the mounting belt. All of the above functions can be useful depending on the nature of the work, so it is worthwhile to determine in advance 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: chucks and gearboxes

Chucks, which are also called spindles, are installed on network screwdrivers and can be of several types depending on the design features. The first version of such a part is a three-jaw key. These chucks are classic and are mounted on drills. They are distinguished by a high degree of reliability when fixing the drill. In the ratings of network screwdrivers, this type is quite common.

Better to give preference to models with a metal gear

Note! The three-cam key elements are capable of fairly accurate alignment. It should also be said that their clamping force is higher than in fixtures equipped with other types of chucks.

The second type of cartridge is keyless, which is considered less reliable. However, hand-held products are more appropriate if the tips need to be changed frequently during operation. An example is the Whirlwind device. This type of drill-driver has an acceptable cost.

Screwdriver keyless chucks are less reliable, but great for home use. Professionals also actively use these types of devices, as they significantly increase the speed of the work performed.

Gearboxes include polymer materials. This significantly reduces their reliability. Of course, the price of this type of drill-screwdriver will be lower, but buying it for active use is impractical. Plastic parts are more susceptible to wear and tear and have a relatively short service life. The presence of a plastic gearbox is permissible only in those models that are purchased for infrequent domestic use.

Keyless chucks are considered optimal for home use.
