Manufacturer's choice
The choice of a drill-screwdriver is an important matter, how the tool will serve its owner depends on the right decision. Popular manufacturers who have long established themselves in the construction market can be called "Bosch", "Hammer" and "Hitachi"
These companies are mainly engaged in the production of household models. They are inexpensive and the quality is generally good.
Popular manufacturers that have long established themselves in the construction market can be called "Bosch", "Hammer" and "Hitachi". These companies are mainly engaged in the production of household models. They are inexpensive and the quality is generally good.
Professional models are developed by Dewalt. The quality of such a tool is undoubtedly better, but the prices are sometimes too high.
There are also domestic manufacturers. And although the prices for their goods are much lower, you do not risk the effectiveness of the tool. Known company "Enkor" and its models "FIT-80014", "DE-450ER / 10". Another good option is “GardenLux CD14-22. The listed models are intended for domestic use. For professionals, "Makita-4700", "Interskol DU800ER" are suitable. Their cost can reach 20,000 rubles. The price of a household product is no more than 7,000 rubles.
Additional functions
As usual, these functions are optional, but they greatly improve the usability. Some even raise the price, it is not at all significant, and some are quite noticeable. To choose the most inexpensive screwdriver, you can get by with a minimum - reverse and the presence of illumination of the place of work. The rest are useful, of course, but more suitable for professionals.
Some additional features are very useful
Reverse or reverse
The presence of this option allows you to unscrew a screw or a drill stuck in the material. The change in the direction of rotation occurs when the polarity of the power supply is changed, which is carried out through a special button. It is usually installed near the trigger.
Examples of the location of the backstop button in a screwdriver
Most often, the button for switching the direction of travel has three positions: on average, the tool is locked. This increases safety: if you accidentally hit the lever, the screwdriver will simply stop and not immediately start rotating in the opposite direction.
Illumination of the working area
A very convenient option that does not greatly affect the price of the screwdriver is the illumination of the place of work. In good lighting conditions, it is much easier to control the instrument.
Work area lighting is a useful additional feature of the screwdriver
An LED is built into the handle or the body of the tool near the chuck, which lights up when the start button is pressed. If you want to choose a screwdriver that is convenient to work with, see that there is a backlight for the place of work.
Battery indicator
If you decide to opt for a cordless screwdriver, it would be nice to have a battery indicator. These are LEDs of different colors - green, yellow, red, which are located on the body. If it is green, the charge is full, if it is red, it is almost discharged.
Battery indicator
The location of the indicator depends on the company, but it is usually located on the thickening of the handle, in the same place as the backlight LED, or in the upper part of the case.
Automatic feeding of self-tapping screws
Such screwdrivers are also called shop screws. This option is useful for professionals, especially those who work with drywall, where fasteners need to be installed in small increments. Self-tapping screws are mounted on a special tape, tucked into the guides, and automatically fed to the holder.
Screwdrivers with automatic fastener feed
This option can be implemented in two ways: there are exactly shop screwdrivers (in the photo on the left) and there are nozzles for a regular screwdriver. For home use, the second option is preferable, since the tool can work as a drill or in reverse. A shop screwdriver is a highly specialized equipment for professional use.
The lineup
The Hitachi DS10DFL weighs 1 kg and has a powerful 1.5 amp-hour battery. It charges very quickly, but the capacity of a single battery may not be enough for intensive work, especially since the torque is not at all happy. Consumers also complain about poorly designed backlighting.
Another Japanese miniature screwdriver - Makita DF330DWE - has a torque of 24 Newton meters
Importantly, this does not interfere with charging the battery in 30 minutes, but even the excellent design does not cancel complaints about the weakness of the cartridge and the appearance of backlash. Connoisseurs consider the Metabo PowerMaxx BS Basic to be the best option - despite its weight of 0.8 kg, the device develops a torque of 34 Newton meters
There are no special reasons for complaints about branded products, you should beware of fakes.
How to choose a screwdriver for home or work
The screwdriver is a hand tool. Its main task is to screw in self-tapping screws. There are simple screwdrivers that can do nothing more than screw fasteners. And there are models that can make preliminary holes for installing screws. This is already a complicated option. In addition to screwing in, screwdrivers have the function of unscrewing, that is, reversing.
There are many important aspects in choosing a tool: engine power, battery capacity, torque, chuck type and ergonomics. An important factor is the availability of various adjustments. But let's take a look at the basic types of screwdriver.

Criteria for choosing a screwdriver
Let's start with a short guide on what to consider when choosing a screwdriver. Full instructions are in our previous article.
Power type:
network. Powerful and relatively lightweight devices that will not run out at the most inopportune moment. The reverse side of the coin is that the wire somewhat limits the range, and if there are power outages, then the work may even stop. Due to the higher power, professional devices prevail among network models;
rechargeable. Differs in mobility and autonomy, can work anywhere, does not restrict movement, but requires regular recharging of the battery. If you have to work a lot, it is better to have a pair of batteries.Do not forget to consider when choosing the battery capacity and charging time, as well as the type of battery - lithium-ion (Li-Ion) and nickel-cadmium (Ni-Cd) show themselves best.
Please note that cordless screwdrivers are less powerful than cordless ones, but there are exceptions;
combined. Combines the convenience of mains and battery
Universal screwdrivers.
Rotational speed. For screwing in screws, 400-500 rpm is enough - any screwdriver can do it. If you are looking for a screwdriver-drill, then this indicator should be about 1200-1300 rpm, and for working with metal, a tool is used that produces 3000 rpm. True, for metal it is better to take a normal full-fledged drill.
Torque. This is the force that the tool exerts on the fastener. The metric tells the user what the tool is capable of. For rare use in everyday life, models with a torque of 10-15 N * m are suitable, but it is still better to look towards models with 30-40 N * m - they are more versatile, they will allow you to work with denser materials. Such a tool will easily cope with the installation of a self-tapping screw up to 100 mm long into a tree. In professional models, the torque can reach 130 N * m. All screwdrivers have a torque adjustment, which ensures comfortable work with different fasteners and different surfaces.
Chuck type. There are models with a keyless chuck. They are more versatile, easy to use, and allow you to install bits, drills, and various attachments. The hex chuck is not as versatile, but the bits can be changed very quickly.
Ergonomics. Especially important if there is a lot of work to be done. Pay attention to the convenience of the location of all controls and the rubberized handle.
What else? The hammer mechanism is an option that replaces the hammer drill for you. The backlight makes it easier to work in hard-to-reach places, and the pulse mode increases the torque. All these functions are at your discretion. Think three times before paying for them. But what is really needed is the reverse. It is available in almost all models and allows you to unscrew the fasteners.
Manufacturer. The tool of Bosch, Metabo, Makita, HITACHI, Hyundai, Dewalt, Sparky, Interskol proved to be excellent.
Now let's move on to the fun part - we are looking for the best models in different categories.
