Recently, both in daily household use and in production, tools such as wrenches have been used. They are a special tool, thanks to the use of which, quickly and without the use of physical force, you can unscrew or, conversely, tighten a variety of fasteners for cabinets, wheels, construction cranes, foundations, and so on.
A wrench, as a rule, is used when there is a need to twist or untwist a variety of threaded connections. Basically, such a tool is used in cases where it is difficult to carry out work with ordinary wrenches. In addition, it allows for assembly or disassembly tasks of structures with rusty metal or unusual nut.
A distinctive feature of this device is that it is additionally equipped with a monitoring function that is triggered when tightening or tightening the fasteners. The editors of the site "bestx.htgetrid.com/en/" have prepared for your attention a rating of the best impact wrenches as of 2020.

Description of the power tool
What are the types of impact wrenches, how much do they cost, what are the criteria for choosing such a tool and how to choose the best device among inexpensive devices? In appearance, the impact wrench resembles an ordinary electric drill with an additional attachment. Consists of elements such as motor, clamping device, spring. Thanks to this attachment, the process of unscrewing or tightening the threaded fasteners takes place. For domestic and home use, these appliances typically use a ½ ”chuck. Cartridges with a diameter of 1 ”or ¾” are mainly used in the behavior of various construction work or during car repairs.
Wrenches are divided, however, like most power tools, into professional and household models. They differ from each other in such parameters as power indicator, drive type, maximum torque level, and so on. In addition, professional models differ from household devices in terms of duration, duration of continuous work.
On a note! Household appliances generally do not have a powerful electric motor, so they do not need an advanced overheating protection system.
The advantage of such household power tools is undoubtedly their low cost. The disadvantage of devices that belong to the household segment is that they are made from lower quality components. They are also not suitable for long-term work.
Which is better, a wrench or screwdriver
Most people, before purchasing such a power tool, often think about what is better to buy a wrench or screwdriver? Answering this question, it should be noted that for performing small, simple tasks, a screwdriver is perfect.However, if you need to do more complex work, it is best to get a wrench, because it is much more powerful than a regular screwdriver.
The main differences between a nutrunner and a screwdriver
| Power tool type | Benefits | disadvantages |
|---|---|---|
| Wrench | + Possesses high power and twisting force | -Heavy |
| + You can set the speed | -It is better not to use for loosening small fasteners (tears off the caps) | |
| + You can choose the most suitable model by the type of connection | -Bulky | |
| + Equipped with impact mechanism (depending on model) | -Exclusively nut heads are suitable for the chuck | |
| -Have a small range that allows you to adjust the torque of the device | ||
| Screwdriver | + Equipped with a universal chuck (drills can be used) | - Not equipped with an impact mechanism |
| + Tightens the rig more accurately | -Suitable for working with small diameter nuts only | |
| + Compact | -Only one speed | |
| + Low weight | -Low torque of fasteners | |
| + The twisting force can be adjusted thanks to the mounted switch on the gearbox |
What criteria should be followed when choosing a nutrunner
- Torque. This parameter is measured in Nm, in which 1 unit is equal to the indicator of the effort from the lever of 1 m. For example, a human hand during operation is capable of reproducing efforts equal to 9 Nm. For such a power tool as a wrench, this figure is from 100 to 2500 Nm. Thanks to the electronic adjustment, the twisting and unscrewing force can be independently adjusted. Thanks to this, the heads can be avoided at the fasteners.
- The type of cartridge used. These units use 1, ½, ¾ "squares. Also, hexagons are quite often used, which has a great influence on the selection of equipment during a variety of works. When choosing such a device, you should pay attention to the method of fixing the heads used. The latch can be equipped with a special ring or a spring-loaded bearing. It does not allow the equipment to fall out of the chuck while lowering the tool down, which is especially convenient when dismantling at high heights.
- The power source being used. These devices can operate directly from a network with a voltage of 220 and 12 V. Also, some devices carry out their work using a rechargeable battery or compressor. The type of power source used has an impact on the parameters of the power tool such as mobility, autonomy and torque. The most mobile and autonomous are devices that work with batteries. However, the most powerful devices are pneumatic devices, but they will have to use a compressor, which in turn makes them less mobile.
- Turnovers. The speed at which the tool chuck rotates can reach 800 - 9000 revolutions per minute. This indicator has a large impact on the performance level of the power tool. Models have been developed in which from 1 to 4 speeds are provided.
- The presence of a shock function. Some devices have a shock function, due to which the device makes so-called tangential impacts during its operation. Due to the presence of such a function, they are able to quickly untwist outdated fasteners covered with a large layer of rust, which can sometimes be very problematic to tear with an ordinary hand tool. For a variety of dismantling work, it is recommended to choose devices that are equipped with a shock function.
- Battery capacity indicator. When choosing a power tool that uses a battery as a power source, you need to pay attention to the parameter of its capacity, which can vary from 2 to 5 A / h. It is on the capacity of the battery that such a parameter as the autonomous functioning of the device depends.As a rule, cordless impact wrenches (depending on the capacity of the battery) are capable of operating continuously for 30 - 180 minutes.
On a note! Impact wrenches, unlike non-impact wrenches, are usually used by professionals to perform complex work. In such devices, the electric motor transmits strong impulses to the cartridge, due to which it begins to rotate much faster. Shockless models are mainly used to solve simple household tasks, carry out repairs, and so on.
Review of the best manufacturers of impact wrenches
Which company is the best tool, which wrench is better to buy, which are the best models on the domestic market?
