How Impact Wrenches Work and How to Use Them

Impact wrenches are used in both professional auto repair shops and for home use. There are two types of these tools available on the market: pneumatic and electric impact wrenches. The difference between the two lies in their power source. A pneumatic impact wrench operates using an air compressor as its power source. This type of impact wrench is very efficient and powerful because it achieves higher torque. Electric impact wrenches, on the other hand, are divided into corded and cordless models. They are slightly less powerful, but can be used almost anywhere. They are particularly well-suited for lighter tasks.

How does an impact wrench work?

Impact wrenches are primarily associated with tire repair shops. This association is accurate in that it indicates what this type of wrench can be used for. Impact wrenches are used to drive or tighten bolts in easily accessible areas, and their main advantage is the ability to minimize the physical force required for the task. Impact wrenches can also be used in home settings. They are particularly useful if you want to change a tire on your car yourself.

What to consider when buying an impact wrench

When choosing the power of the tool, we need to consider how often we will use it. Of course, tools for professional auto repair shops usually need to have significantly more power than those intended for home use. Professional impact wrenches can boast power reaching up to 4000 Nm. However, the standard power of these tools typically ranges between 1000 and 1500 Nm at maximum output. Of course, before deciding on a specific product, it’s also worth checking the working torque, which should remain at no more than one-third of the maximum torque. It’s worth noting that power isn’t the only parameter worth paying attention to. The wrench must also be comfortable and ergonomic.
