When purchasing any kind of electric tool, every consumer wants it to last as long as possible. In order to achieve this goal, you need to carefully approach the choice, taking into account all the subtleties and features of the equipment. When choosing a tool like this, you should understand the margin of safety and modifications. An electric wrench is sure to come in handy in everyday life for those who use wrenches quite often, which is very laborious. Having spent once, you can use the tool at any time. Many do not consider it necessary to buy such a tool, since you can always visit a tire shop to perform minor tasks. If you often have such a need, it is best to visit the store in order to purchase an electric impact wrench.
How to choose the drive type
Wrenchelectric can work from a network of 220 volts. This type of such a tool is the most common, every builder must have seen it. It is worth noting that this tool, in fact, is an electric drill equipped with a nut attachment and some other modifications. You can use such a unit to solve any problems, and you can use it both in tire fitting and in everyday life. Such an electric wrench has an optimal ratio of quality and cost. You can also choose a tool that runs on battery power. Such a modification is no less popular, but you should be prepared for less impressive power. You can use it to solve everyday problems, since it is not recommended to trust responsible work to such a tool. As the battery discharges, the tool loses power. Portability can be singled out as the only but significant advantage. You can take such equipment with you to the roof for screwing rafters or logs. You can not do without such a tool when performing appropriate tasks in places where there is no access to the electrical network. Summer residents appreciate this feature. It is not recommended to purchase an electric wrench for solving one-time tasks, since such a purchase is not advisable.
Impact mechanism reviews
According to DIYers, nothing makes an impact wrench as useful as special features, features and attachments. For example, when choosing, you can prefer a model that has a percussion mechanism. Such a unit is something similar to a perforator. A striker works in the tool, which helps to increase the effort. Home craftsmen emphasize that this functionality is useful for tightening nuts and unscrewing, for example, car wheels. Using a conventional apparatus, there is no way to unscrew a nut that has been subjected to a rusting process under the influence of water for several years. It is necessary to take into account the fact that the cost of a power tool with an impact mechanism will be much higher, but these costs can be called reasonable.
Tightening force feedback
Electric impact wrench may have the ability to adjust the tightening force. This feature, according to buyers, should not be neglected at all. If you have to work with a weak thread, then it can be torn off at the first manipulation. If the tightening force turned out to be acceptable, this trouble can be avoided. You can make adjustments yourself by turning off the percussion mechanism. However, this approach is lengthy and inconvenient. The easiest way is to purchase a tool equipped with a regulator. It will keep the threads and evenly tighten the connection. This functionality is claimed by users to be useful when installing heads on a machine.
Gear form factor reviews
Electric impact wrench can be equipped with a reducer form factor. Not always with a conventional drill by typea pistol has the ability to solve all problems. Sometimes there is a need to use a gear mechanism for nuts that are located in hard-to-reach places. Quite often you can find arc-shaped and straight wrenches, but it is recommended to purchase them only when absolutely necessary. In everyday life, the use of such tools is inconvenient, and they will be more expensive to maintain. It is impossible not to mention the significant cost: thus, the corner apparatus will cost 1,300 rubles more.
Characteristics of different materials used in the manufacture of tools
Electric impact wrench, the price of which will be higher with additional functionality, can be made of different materials. When purchasing a tire fitting tool, you should not overpay for the comfort of use and beauty. However, if the product is supposed to be used at home, then for this it is recommended to buy a unit that will not only be pleasant, but also as comfortable as possible. If we talk about the material, then metal is durable, while plastic cannot be called such. But in some cases, expensive models are made of plastic. As for the working units, they are made of metal and brass. When making the holder, manufacturers who have established themselves in the market for their respective products use high-strength plastic, which is supplied with rubber pads.
Comfort features
If you decide to purchase an electric wrench"Makita", it is recommended to pay special attention to the presence of additional handles. Many options have several places for fixing additional holders. It is best to prefer just such a model, as it can facilitate the work. An electric cargo wrench must contain rubber pads, as they prevent hands from slipping on the surface. It is worth remembering that such an addition significantly increases the cost, as the appearance and comfort become much better. The consumer will have to pay about 800 rubles on top for such an improvement. When choosing an electric wrench for a car, you should pay attention to the presence of a convenient trigger. Most options have a massive handle that replaces the button. It's comfortable enough to grip. Experts recommend abandoning the small trigger, which can be damaged during operation, and holding it will be quite inconvenient.
Tool power and torque
If you decide to purchase an electric impact wrench, it is important to pay attention to the power, which acts as one of the main characteristics in mechanical units. The figure will depend on performance, service life without stopping, as well as the speed of work. If we are talking about a household model, then the power can vary from 400 to 500 W, while in hydraulic and pneumatic versions, the power should be much higher. By purchasing an electric wrench for trucks, youshould also pay attention to the torque, on which the force of pressure on the nut depends at the moment of unscrewing. When it comes to household models, the torque is kept at around 600 Nm, this figure is sufficient to unscrew a regular nut, not pinched, not painted over with several layers of paint. Otherwise, the nut will not be on the “teeth” of the described apparatus. If more torque is needed, then you will have to purchase a pneumatic or hydraulic model, which can reach 2500 Nm of torque.
Rotation speed and nozzle size
When choosing an electric impact wrench, the price of which can be equal to 75,000 rubles, you need to pay special attention to the speed of rotation. For the described category of instruments, this parameter acts as one of the most important. Professional nutrunners show speeds ranging from 6000 to 8000 rpm at maximum speed. Household tools keep this indicator within 2000 rpm. The instant stop function is also related to the rotation speed. Such tools are called torque tools and are used exclusively for high-precision work. An electric wrench, the price of which is sometimes much higher than mentioned, may involve the use of different nozzles. Household models are more often used in tandem with nozzles ranging from M12 to M24. Professional options involve the use of nozzles with a more impressive range. Such tools are used for trucks. In professional models, the change of nozzles is carried out quite quickly due to the presence of a clamping mechanism. In this case, you do not have to use the key, only one hand will be involved, which is important for professionals who spend a lot of time changing nozzles.
Reverse tool characteristics
When choosing a type of wrench, it is important to first decide whether you need a reverse, since not all tools in this category are equipped with such functionality. If the device has such a feature, then it will show the ability to tighten and unscrew the nuts. In professional instruments, this feature is especially appreciated. If you use the device to solve everyday problems, then you can completely do without a reverse, while the cost will be much lower.
Presence of secondary factors
Succumbing in the process of purchasing a wrench to indicators of the main characteristics, the consumer does not always pay attention to some secondary factors. These include the design features of the case, the ergonomics of the unit, the convenience of the handle and the center of gravity. In sum, all this will allow you to use the tool for a longer time, doing the job without getting tired. Thus, when choosing battery models, you may encounter the problem of an impressive weight of an electrical appliance. But its presence excludes the binding of the tool to the network. The battery is charged inwithin an hour.
Conclusion
If you decide to purchase a wrench for your own needs, then you need to exclude all the functionality that will not be used by you every time you operate the equipment. This will save a lot, but will reduce the comfort of use, which is not always true. Indeed, in the conditions of your garage, it is not so often necessary to carry out tasks that involve the implementation of a large amount of work. Experts do not recommend saving, as the purchase should be durable.
