Best cordless screwdrivers for 2020

For those who are constantly faced with minor repair work, where it is necessary to tighten screws, a cordless screwdriver will be an excellent purchase. It makes it easier for your hands to work, is less cumbersome than a screwdriver, therefore it is suitable for narrow spaces and hard-to-reach places. In addition, this tool is multifunctional due to the large number of attachments. How to choose a cordless screwdriver?

Criterias of choice

Any device must be selected, paying attention to the characteristics. Different indicators are suitable for different functions to be performed. It is worth paying close attention to the following information, because it will help you choose the best option on the market.

Torque

The first and one of the important criteria, since the screwdriver must turn well. This indicator changes in Nm. For soft materials, small fasteners and small drilling, 2-4 Nm will do. For large drills and fasteners, hard materials, 10 Nm is needed. There are also professional tools with a rotating force of up to sixty Nm. By the way, an ordinary manual screwdriver with its own forces has only 4 Nm. To improve the mechanism, a reducer is built in, which reduces the speed, while increasing the torque. This helps the electric motor run more efficiently. In addition, some models have a regulating clutch. It allows you to avoid unnecessary twisting of the screws, folding their heads.

The criterion is divided into hard, soft, long-lasting, maximum. However, despite this classification, there are no uniform standards and indicators by which the exact type of torque is determined. Because of this, screwdrivers from the same category may have different performance.

Rotation frequency

This is the maximum number of revolutions for a certain period of time. Most often measured in rpm. Cordless screwdrivers usually have two values ​​at once: high and low, between which you can easily switch. For screwing, 100-300 rpm is enough, and for drilling - at least 600. High rotation speed is very important in drilling. So, in drills this figure reaches 2100. Since the speed most often switches, pay attention to the highest figure. If you are not going to drill a lot, you do not need to overpay for it.

Battery

Typically, there are two types of batteries in these tools: lithium-ion (Li-lon) and nickel-cadmium (Ni-Cd). The first ones are good in that they store energy much more, while consuming it for a long time, and charging is possible at any time, since such a power source does not need to be completely discharged. The latter are not damaged due to overcharge and large discharge, withstand high currents, are able to work in frost, are easy to charge, keep voltage throughout the entire work, and charge very quickly.

It is worth paying attention to the battery capacity. It is measured in ampere hours. Over time, the capacity decreases, especially in lithium-ion.Cheap models usually have the weakest batteries. Accordingly, the operating time of the tool will be shorter.

How to choose?

Knowledge about the performance of this device is not enough to determine which model is suitable for the specific needs of the consumer. Do not rely on the principle "the higher the performance, the better." Usually such models are really expensive, but they also serve for a completely different purpose. It is worthwhile to clearly form the purpose of using the instrument before buying it.

By price

Let's look at the price ranges to understand how expensive and cheap models differ:

Up to 1,500 rubles - as a rule, the simplest, most compact and lightweight models that have low power and are suitable for simple bolt tightening. Such work can be done manually, but some people prefer not to make so much effort and take an electrical appliance.

From 1,500 to 5,000 rubles - the most popular models are located in this price range. They already have a complicated configuration, are more powerful, often have attachments of various shapes and for different purposes, a good battery, an easy charging system. In general, for a good screwdriver, this is the most optimal price if you do not need to perform too complex tasks. They are more reliable and versatile than the first group.

From 5,000 rubles, there are models with the highest torque. Usually there is an additional battery, as well as attachments of different shapes. This allows you to significantly expand the range of application of the tool.

By purpose of use

It is necessary to understand what indicators are better to pay attention to. As a rule, different types of screwdrivers are needed for different areas of activity. Somewhere a rather low rotational speed, but somewhere the other way around.

Furniture

For comfortable assembly and disassembly, as well as furniture repair, the cordless screwdriver must have an above average torque. Switching on rotation speed must be present to switch to drilling mode. The presence of a backlight, as well as an eccentric and angular nozzle, will greatly simplify the work.

Those who are professionally engaged in this on an ongoing basis, as a rule, have two screwdrivers at once. One is larger and more versatile, the second is smaller, for hard-to-reach and narrow places. In addition, a screwdriver is used as the main tool.

For home

How often do you have to screw something in the house? Hardly, more than once a week. For such purposes, you should not buy an expensive device, because with this money you can buy something more useful. It is simply not rational to spend a large amount of money on a tool, which, by and large, will simply lie in the box. That is why simple budget models are perfect. The main thing is to choose with a good battery so that it does not run out of power in standby mode. The Ni-Cd version will do. Rigging бит or bits can be safely taken from another tool or purchased later. There will be no special problems with this. A simple budget model is the best option.

Computer

There are special subtleties in working with this subject. For such material, a small screwdriver with low power is suitable, always with torque adjustment. The most suitable battery will be a lithium-ion battery, since this way the tool is always ready for use. Tip: it is better to choose the equipment separately, on special resources.

Which company is better?

There are a lot of manufacturers of this product. There are both Soviet and foreign manufacturers. Basically, everyone has good sample models, so it's best to look at the reviews. However, here is a list of manufacturers whose screwdrivers are always on top:

• BOSCH is a German home appliances company with a long history. Her devices have always delighted in quality. This feature has not spared such a segment as cordless screwdrivers. Small models are some of the best on the market. Good materials, equipment and high performance. Buying their product, you can be sure that it will last a long time.
• VORTEX is a Russian company with production in China.They are engaged in the production of electrical engineering at a high level. All products undergo strict quality control. The manufactured goods are very popular. The price segment is quite budgetary. Cordless screwdrivers of this brand are at their best!
• Hitachi is one of the largest companies in Japan. She is known all over the world for her products. Their range of cordless screwdrivers offers high performance and excellent quality. They are expensive, but they fully justify it.

Tips before buying

This tool can greatly simplify housework, especially if it is chosen correctly. In addition to physical characteristics such as torque, maximum speed, voltage, battery capacity, there are also real ones. Try to look at the shape of the tool before buying. Which screwdriver sits better in the hand, which is more convenient to work, which does not impede the movement of the hand. The main thing is that the tool is comfortable and of sufficient breadth. Its mass is also very important. One way or another, the device will need to be held in hand, you need to choose the model that will provide the most comfortable working conditions.

Another important element is the type of charging and battery. Some devices have a USB cable, which greatly simplifies the charging process, because this can be done with virtually any USB cable, so if the factory one becomes unusable, you can immediately replace it. This is a huge advantage over special cords that are only suitable for charging one device. The situation is similar with batteries. It is better to take a tool with a removable battery, otherwise, after its expiration date, you can say goodbye to the screwdriver. If the battery is removable, you can easily replace it with a new one. The device will work just as well.
