Widely used by professionals and home users, the pneumatic impact wrench is an indispensable tool in tightening and loosening high torque. It is very popular among professionals because of its power. The choice of this impact wrench is very difficult because the range is very wide and the brands are very varied. To help you see more clearly especially if you are still a beginner, we offer a selection of criteria that will be of great help. Indeed, pneumatic impact wrenches are distinguished from each other by:

Air consumption

Depending on the power, the pneumatic impact wrench requires a certain level of pressure and a compressed air flow capable of operating its engine. Therefore, you need a compressor adapted to the compressed air requirements of your pneumatic impact wrench. Therefore, it would be wise to choose a compressor with a tank size sufficient to power the impact wrench. As an indication, to operate the smallest of the nutrunners, it is necessary to provide a tank of 50 liters minimum.

The power that results in the tightening torque


This is the indicator that reveals the ability of the wrench to tighten and loosen the screws and nuts. It is expressed in Newton (Nm). The more powerful the key, the more it would be ideal for intensive works in different fields: the metallurgy, the heavy weight, the automobile sector …

The number of impacts

We are talking here about the speed of execution of the pneumatic impact wrench. The higher the number of impacts, the faster the screwing or unscrewing of the nuts.

Ergonomics

The design of the impact wrench in general and that with compressed air more specifically is very important. First, choose a tool designed with lightweight materials. Indeed, the heavy weight of a manual DIY tool is a real handicap during its use. Therefore, it would be wise to use small keys to be able to use for long periods.
The design of the impact wrench must have it to operate in the smallest places and the least accessible corners. The coating of the handle is very important. It plays a crucial role in a comfortable and ergonomic grip. In addition, such a product would be more manageable and easy to use.

The budget

Before you get a pneumatic impact wrench, you should know that this category of product is the most expensive. Indeed, it is more expensive than an electric shock or cordless wrench. If you want to equip yourself with a pneumatic impact wrench for occasional use, you do not have to choose a high-end product.
However, if you want to use it for intensive work, it would be wise to choose a powerful model and a little more expensive. As an indication, with a budget of 30 euros, the novice handyman can find pneumatic impact wrenches with a torque strong enough capable of reaching a level of 300 Nm. Professionals can be offered a very powerful model with a couple over 1000 Nm with a budget that varies between 100 and 250 euros.

Tooling

It is important to bring to your attention that the pneumatic impact wrench is equipped with a male square. On the latter, the handyman can fix bits and sockets adapted in size and profile to the part to be tightened or loosened. The sizes of the squares of the bits and sockets are expressed in mm or in fractions of an inch (inch: 1/2 ”, 3/8 ”).

Conclusion

Whether you are an experienced professional or an amateur handyman who is taking his first steps in the world of DIY, a key impact is a must for successful tightening and loosening properly, effortlessly and in less time. The pneumatic impact wrench is the most powerful because of the supply of compressed air. In short, the impact wrench is a very useful and practical tool provided you study its characteristics and adapt them to your needs.
