How to choose a wrench: pneumatic, electric, cordless?

One of the most popular types of tools is the impact wrench. It is designed to tighten (loosen) threaded connections. The tool is indispensable both in the home workshop and in service stations and in production. It is important to read this article in order to choose the right wrench.

Torque

This criterion depends on the capacity of the device. When choosing a tool model with different torques, it is necessary to take into account the purpose for which the tool will be used. To perform operations in the home workshop, you can opt for models with a torque value of no more than 160 nM. For automotive workshops or manufacturing, it is recommended to choose tools with a torque of 1000 nm or more.

Rotor speed

The maximum indicator of this parameter reaches 8 thousand revolutions per minute. As the rotor speed increases, the time required to complete the operation decreases and the power of the equipment increases.

The electric impact wrench requires a stable AC network to function properly. This type of nutrunner covers a wide power range, has a slight reduction in the set torque, low noise level due to the silencer built into the handle and a relatively low weight. Has a built-in torque power regulator. Using the reverse mechanism, you can choose the direction of rotation: clockwise or counterclockwise. The force of the electric impact wrenches can range from 50 to 6500 Nm, and the weight from one to ten kilograms.

Electric impact wrenches are highly efficient and reliable. This type of tool is used in the automotive and heavy industry, as well as in the petrochemical industry. The equipment is versatile due to a huge variety of additional attachments.

An electric impact wrench works on the basis of an impact-rotary mechanism that converts impact impulses into rotation. The direction of movement for unscrewing or twisting is set by the switch.

The main technical characteristics of electric impact wrenches are: speed, power, and maximum torque. These are the main characteristics of the impact wrench, which are related to each other and the higher they are, the higher its performance. Its weight also depends on its main characteristics. When buying a nutrunner, it is necessary to correlate the tasks ahead and its technical characteristics. Do not forget about the convenience of using this tool, which can be provided by a comfortable handle covered with a vibration-insulating and anti-slip layer, as well as all possible indicators, additional handles, lighting of the working area, etc.

Cordless wrenches

The main advantage of the cordless impact wrench is mobility. People who value mobility will settle for this option. Indispensable on the road or in places where there is no power supply. With a cordless wrench, it is easy and quick to unscrew bolts and nuts (even rusted ones), you can also fix any part. Such a tool, due to its mobility, becomes the choice not only for professionals, but also for ordinary buyers for household needs. For example, it is an indispensable tool for car owners, with the help of an electric wrench, you can easily unscrew the wheel.

Since electric impact wrenches work on the principle of impulse rotation. They are often equipped with a switch to select the direction of rotation and a torque power regulator.

The main parts of the cordless impact wrench:

  • Lever;
  • Housing;
  • Cartridge;
  • Battery.

Impact wrenches are considered the most effective among electric ones. When working with such a tool, the torque value is significantly increased due to a series of blows, which add up to a rotational movement.

The main technical characteristic of a cordless nutrunner is the torque, the larger it is, the larger the bolts and nuts you can tighten. Its range is from 60 to 1000 Nm. Another important characteristic is its rotational speed (beat frequency), on average about 3 thousand revolutions per minute (rpm). Its performance and battery life can be determined by voltage and capacity. The more powerful the model, the more weight it has. If convenience during its operation is more important to you for work, then be sure to pay attention to this feature, and choose a lighter and more convenient wrench, but with a less powerful battery.

The first thing you may have problems with is which type of drive to choose. The pneumatic drive uses compressed air and therefore requires a connection to a compressor. Such models are popular at tire shops and service stations where saving time and money is important. A hydraulic wrench uses the movement of a hydraulic cylinder, which is connected by an axle with a ratchet mechanism, which creates the greatest force and is intended for the chemical industry, agriculture, and underwater work. The electric wrench has a motor built into the housing and is powered by the mains. Such a tool is convenient to use and differs in mobility from other types of drive, therefore it is so popular in everyday life and during construction installation work.

Food type

The main advantage of battery technology is portability, but such equipment loses its power during operation. You can use network wrenches from the cigarette lighter, having the necessary adapter in your arsenal or directly from the battery, and you can turn the nuts even in an open field, due to the lack of a battery, they are easier.

Basic characteristics

When choosing an electric impact wrench, the impact model is much preferable to the shockless one, because the impact mechanism acts on the nut with strong impulses, which increases the productivity of the tool, unscrewing even old stuck bolts. The price for such equipment will be higher, but the costs are justified. Take into account the maximum torque indicator: maintenance of a car or assembly of furniture is enough 100-200 Nm, for the installation of any metal structures 300-600 Nm will be enough, and for servicing trucks you need a professional unit from 1000 Nm and above.

What other features will come in handy

We advise you to pay attention to the additional functions that the electric wrench has:

  • Reverse (rotation both clockwise and counterclockwise);
  • Diode lamp for illumination;
  • Additional rubber handle with anti-slip surface;
  • Overheating and power surges protection;
  • Battery charge indicator.

Feedback from our customers confirms that the additional handles, backlight and battery indicator add convenience and comfort while using this equipment.

The choice of the required model of an electric impact wrench is not an easy task, not only for a novice user, but also for a specialist. Pay attention to its special functions. Electric wrenches are presented on our website with adjustable torque impact type. Impact wrenches can be compared to a hammer drill that increases the applied force. The presence of an impact mechanism is simply necessary for nut connections when tightening / unscrewing wheel bolts. The price of such a wrench will certainly be higher than its counterparts, but when working with trucks, you cannot do without it.

Automotive Electric Impact Wrench

At home, the most commonly used electric wrench is used to loosen the nuts on the wheels of a car. This tool is more in demand during the period of mass replacement of rubber. Compared to a conventional wheel wrench, the impact wrench speeds up the process of loosening and twisting wheels tenfold. Such a device will come in handy for everyone who does not want to contact a car service, as well as spend time and effort on routine work.

The power source for an electric wrench can be a replaceable battery, a network, as well as a car cigarette lighter. Cordless impact wrenches are mobile and can have good torque, but they are not practical. Due to the high consumption of electricity, even for professional models, the charge lasts for 10-20 minutes of continuous operation. Wrench batteries, in contrast to a screwdriver, must constantly produce strong voltage. The cost of such batteries is sometimes close to the cost of the impact wrench itself, so some manufacturers do not include them in the tool kit, making the price more attractive.

The most practical companion on long journeys is a 12 volt automotive impact wrench. Such a device can be powered by a cigarette lighter or directly from a car battery. It has good torque and can handle wheel changes on the road without any problem.

how to choose an electric impact wrench for automobile

The corded impact wrench is best suited for stationary work in a garage. Such a tool will not “weaken” at the most crucial moment and will work as long as there is voltage in the outlet. From network tools, in car services, a rolling electric wrench is often used. This specialized device has a wheeled construction and practically does not transmit vibration, despite its high power.

Electric wrench device

According to the principle of operation, an electric wrench has some similarities with a screwdriver, although it has a number of significant differences. When comparing an impact drill to a similar impact wrench, the latter has a significantly higher torque. The impacts of the wrench are in the direction of rotation when they are directed along the axis of the tool on the drill. If we compare a cordless wrench and a screwdriver in terms of operating time, then the charge of the wrench will dry out many times faster due to the increased current consumption. If you want to know in more detail how a screwdriver differs from a nutrunner, there is a suitable article on our website.

There are several impact wrench mechanisms: rocking dog, pin clutch, pin less and double hammer. These elements have a direct impact on the power, quality and price of the tool. When choosing an electric impact wrench, it is useful to know on what principle it works.

Rocking dog has a simple device with a minimum of parts. Quite noisy in operation, but with a good power reserve. This mechanism is less prone to wear and tear and can last a long time even in inexpensive models.
Pin clutch one of the most common mechanisms of electric impact wrenches. Consists of many small parts, the quality of which directly affects the tool life. It has low power indicators and minimal vibration. If you want to purchase an impact wrench with this mechanism, look towards trusted brands, as its parts can easily become unusable.
Pin less simple and quiet mechanism with acceptable recoil. In terms of power, it keeps the middle ground between rocking dog and pin clutch. It has a single impact mechanism for higher reliability and longer tool life.
Double hammer mechanism with a robust design and the highest torque. It is mainly used in industries where the tool can be in operation for hours. suitable for professional use than in everyday life.
