Carefully! Electric current | 06.12.2015
Many home craftsmen use cordless screwdrivers and consider them the most convenient way to screw in or unscrew various fasteners. But before purchasing this or that model, you need to consider the features of such a tool. To choose the best option, it is worth considering the most popular cordless screwdrivers, reviews of which indicate their reliability and convenience.
Why do you need a cordless screwdriver?
Many men use a standard set of tools and do not experience any difficulties, so why do you need a cordless screwdriver? The difficulties of using conventional screwdrivers are due to the fact that working with them is very energy-consuming; you cannot work with a standard screwdriver for several hours a day, and if you conduct such an experiment, then the next day you can say goodbye to your brush.
A cordless screwdriver saves a lot of time and allows you to perform all operations with ease. Moreover, the tool has a large number of bits for working with different fasteners. Another advantage is its compactness. Where a regular screwdriver can't handle it, a screwdriver can go almost anywhere.
Decide on tasks
Before you decide which sewing machine to buy for home use, you should determine for yourself why you will need it and how you plan to work with it. The answer to this question is important so that, on the one hand, you do not buy a unit that is too expensive, most of whose functions you will not use, and on the other hand, so that you do not end up with a machine whose functionality is insufficient to implement your plans.
If you need a machine to perform simple operations, for example, hem towels or tablecloths, sew a patch, sew simple clothes from easy-to-work fabrics, you can pay attention to not the most expensive models that have a basic set of functions - for example, Brother LX-700
If you plan to sew quite complex things or work with difficult fabrics, you may need a larger number of operations and advanced functionality. If you are an experienced craftsman and do a lot of sewing professionally, perhaps an industrial sewing machine is right for you. Such machines are powerful, expensive and require a stationary workplace. Beginners and even most advanced users probably won't need them.
Screwdriver characteristics
Before deciding to purchase a particular model, you should carefully consider the main characteristics:
- type of tool handle;
- power;
- the material from which the screwdriver shaft is made;
- battery type;
- presence of reverse;
- battery charging time.
The handle of a cordless screwdriver can be of two shapes - L-shaped and T-shaped. Devices of the first type are excellent for many jobs and are distinguished by their compactness and lightness. Their shape allows you to work for a long time without worrying about hand fatigue.
If we talk about power, it is worth mentioning that the higher it is, the higher the cost of the screwdriver. If you need to tighten a lot of fasteners every day, then it is best to choose an expensive model whose service life is extended.
The power of cordless screwdrivers is expressed in torque. If you need to tighten screws on electronics, then devices that produce a value of 2-2.5 Nm are suitable. The best option for working at home is to buy a screwdriver with a torque of 4-6 Nm . There are also devices with an indicator of 15-18 Nm. But their cost is high, and their weight contributes to rapid fatigue during work.
Also, by the cost of the tool, you can judge the quality of the rod used in it (the main part of the mechanism that ensures the rotation of the bits). It should be made of high-alloy steel that does not break with prolonged use. The rod is a cylindrical piece onto which the bits are installed.
Typically, these screwdrivers use either lithium-ion or nickel-cadmium batteries. According to reviews, the first type discharges slowly, is unpretentious, but its lifespan is about 3 years. The second one has a “memory effect”.

The difference between a cordless screwdriver and a screwdriver
If you compare a cordless screwdriver and a screwdriver, the second device is more functional and allows you to perform many operations. In addition, it can work with both wood and metal. The screwdriver is suitable only for household needs. But then why buy it?
Purchasing a screwdriver can be beneficial if it is used, for example, for assembling furniture. Using a heavy screwdriver to perform many simple tasks is completely ineffective. Moreover, such products are in demand not only among ordinary users, but also in the construction industry, so they can be safely chosen for work at home.
Also, special attention should be paid to the type of handle. The choice depends on what kind of work will be done with a screwdriver. T-shaped tools have greater maneuverability and allow you to work even in hard-to-reach places.
The main distinguishing features of cordless screwdrivers:
- They are not designed to be used with a drill. The cordless screwdriver is designed for hex bits only. However, you can also find special drills, but their number is limited and does not allow you to replace a screwdriver.
- Screwdrivers can have different shapes. The screwdriver is presented only in the form of a pistol.
- Screwdrivers have a battery located inside the handle, which is one of the main features. In a screwdriver, this part is located lower and is removable
- Screwdrivers rotate at only one speed (most often).
- Have less weight
Price issue
A cordless screwdriver is a tool that is quite affordable - its average price can vary from 1,600 to 4,000 rubles, but there are models that are much more expensive, about 3-4 times. Their price can reach 12,000 rubles.
As a rule, these are models for production professionals. Whether a cordless screwdriver is equipped with sets of bits of different calibers, special attachments, a case or cover can also affect the price.
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.
Because the mood with which the tool will be used, and, therefore, the quality of the construction work, depends on both.
MAKITA cordless screwdrivers
MAKITA screwdrivers are powerful and compact devices for working with fasteners. Some models allow you to use the tool with both an L-shaped handle and a straight handle. This happens due to the ability to rotate the handle. The device has a rubber coating, which makes it easier to hold in your hand even during long-term use.
According to reviews, the tools of this company are convenient and functional, and their build quality allows them to compete with other manufacturers.
Typically, such tools operate on nickel-cadmium batteries, which are lightweight and provide about 5 hours of continuous operation. The devices of this company are intended for household and semi-professional use. This suggests that MAKITA screwdrivers are perfect for housework.
The battery is fully charged, according to customer reviews and the presented technical specifications, in just 3 hours. However, this can happen while the device is operating.
What you need to know when choosing an electric screwdriver
Before choosing a good electric screwdriver, you need to understand what kind of work you will need the tool for and study the technical specifications.
Screwdrivers with a pistol grip are suitable for work in free access. It is necessary to pay attention to the quality of the gearbox.
For large volumes of work, it is best to purchase a tool with a replaceable battery. If we consider an electric screwdriver with a built-in battery, then by far the best option is one with a USB port. Such a device can be charged via a power bank and even recharged at a bus stop.
It is also necessary to familiarize yourself with the ratings of tool manufacturers.

How it’s arranged and what’s included
The operating principle and design of the tool is the same as that of a screwdriver. But there are two main differences:
- Power.
- Construction and weight.
A cordless screwdriver has less power and this is completely justified. It is not suitable for creating holes. That's why it has a smaller battery. The charge of such a battery allows you to perform all the functions of the tool. Actually, because of this, the screwdriver is smaller in size and weight.
Electric screwdrivers have the following configuration:
- Battery. Above are the battery types. The screwdriver battery is selected depending on the frequency of use of the electric screwdriver.
- Battery protection circuit. Can only be used with Li-ion batteries.
- Start button. It can be used to turn on the device, but it cannot be used to regulate the speed.
- Reverse button. Used to switch the direction of movement: unscrew or tighten.
- Electric motor.
- Spindle with chuck.
- A gearbox that allows you to adjust the speed.
- Indicator showing charge. Not all devices have such an indicator.

BOSCH devices
