Today we will talk about cordless screwdrivers – a tool that has earned the respect of many craftsmen from different professions, including electricians.
Modern building industry
In today’s world, the construction industry is gaining momentum every year.
In construction, it is impossible to do without reliable, high-quality tools of various kinds. They are needed both in production and in the household.
And far from the last place in the list of all kinds of tools is occupied by a wide variety of screwdrivers.
Their main function is to unscrew and screw fasteners that have a slot on the head and a thread, such as screws, screws and self-tapping screws.
What is the advantage of a cordless screwdriver
Relatively recently, electric screwdrivers appeared on sale – screwdrivers with an electric motor and powered by a rechargeable battery – a battery built into the screwdriver handle and supplying electricity to run the engine.
In turn, the battery-powered motor drives the tip of the screwdriver.
At the same time, the worker has minimal impact on the screwdriver itself and spends a minimum of effort on the process of screwing or unscrewing, while at the same time being able not to remove the tip of the tool from the groove, which makes the work simple and easy.
No need to explain that such a tool would be very necessary for electricians.
However, it is quite acceptable to use a cordless screwdriver as an ordinary one – for unscrewing and screwing fasteners manually.
Currently, electric screwdrivers are the most modern type of screwdrivers and can be used when installing various household appliances, assembling furniture, installing sockets and switches, attaching wires, and for repair work of any volume.
One of the most important characteristics of a cordless screwdriver is its compactness, convenience and lightness, which significantly outperforms a drill driver, as it allows you to work in poorly lit and hard-to-reach places.
This is possible thanks to a special indicator that allows you to see the direction of rotation.
Cordless screwdriver or screwdriver?
When working with a cordless screwdriver, you need to consider that it will be functional when exposed mainly to soft materials, such as plastic or wood.
It would be unwise to try to screw fasteners with an electric screwdriver into a concrete or metal surface. It is more convenient to do this with a drill-driver.
And it is this drawback that makes the electric screwdriver less functional compared to the drill-driver.
Therefore, with a possible choice between a cordless screwdriver and a drill driver, it is necessary, first of all, to decide what material will be affected – soft or relatively hard.

And also take into account for what purposes the purchased tool will be used – for screwing and unscrewing fasteners or for drilling holes.
Drilling holes with an electric screwdriver is simply unprofitable and energy-intensive, since this process takes a lot of time and effort.
Here, a drill driver is more applicable, since, compared to it, a cordless screwdriver is a single-speed tool, and the speed of its tip can only be adjusted by pressing the power button.
Another disadvantage of cordless screwdrivers is the lack of a cam mechanism to hold a replaceable drill, despite the fact that they are equipped with sets of specialized fasteners and hex bits.
However, cordless screwdrivers manufactured by companies such as METABO POWERGRIP and POWERMAXX do not have this drawback, and have a keyless chuck mechanism in their design.
In addition, electric screwdrivers from POWERMAXX capable of operating at two speeds.

Criterias of choice
The main criteria for choosing a cordless screwdriver are the following parameters:
1. First of all, it is necessary to focus on the convenience of the handle of an electric screwdriver, which can be “screwdriver” or “pistol” in shape.
Its configuration can also be changed, transferred from the “screwdriver” position to the “pistol” position, which allows you to make working with the tool more comfortable.
If you choose an electric screwdriver with an uncomfortable handle, which will not be in close contact with the palm, this will lead to difficulties in work, injury to the skin of the hands, and rubbing of corns.
It is advisable to choose a screwdriver with a rubber-coated body. Rubber will facilitate the use of the tool and make it more ergonomic.
2. A high-quality cordless screwdriver, as a rule, has a shaft made of high-alloy steel, which determines its long warranty period. A screwdriver with a low-quality steel shaft can last less than a month.
3. If there are a large number of replacement tips in the kits offered for a cordless screwdriver, it would be useful to consider whether it is worth buying those kits that contain rods that are unlikely to be used. It is more profitable to purchase a kit with fewer stings that will be used for sure.
4. When buying a cordless screwdriver, you should not forget that the more powerful its electric motor and the larger the battery capacity, the higher the performance and the longer the tool can be used until the next recharging.
A powerful electric screwdriver makes the job much easier than a screwdriver with a smaller motor, although it costs more.
In addition, a spare battery, which can be used while the main one is on charge, will not hurt – this will provide additional time savings.

Price issue
A cordless screwdriver is a tool that is quite affordable – its average price can vary from 1600 to 4000 rubles, but there are models that are much more expensive, about 3-4 times. Their price can reach 12000 rubles.
As a rule, these are models for production professionals. The price can also be affected by the complete set of a cordless screwdriver with sets of bits of different calibers, special nozzles, a case or a cover.
Thus, when choosing a cordless screwdriver, you can be guided by both the above criteria and the price and reputation of the tool manufacturer.
It is much more important that the qualities and characteristics of different brands, including proven ones, meet not only the needs of the consumer, but also his financial capabilities.
Since it depends on both those and others with what mood the tool will be used, and, therefore, the quality of construction work.
