Buying Guide to the Best Impact Wrenches
What is an impact wrench?
An impact wrench is a tool that is used to tighten or loosen screws or lug nuts. When you walk into a mechanical workshop, you might have heard a loud whining sound. In most cases, the high-pitched sound comes from the impact wrench.
If you are a fan of car racing, these tools are the tools that allow a drivers’ team to change the cars’ tires so quickly.
What are the advantages of Impact wrenches?
You might wonder why to opt for an impact wrench when an electric drill can do the same thing. Well, the impact wrench is a better option for several reasons.
First of all, it is more powerful than electric drills. Hence, it does a more efficient job of loosening different types of fasteners: including rusted ones.
Additionally, impact wrenches deliver more torque, less weight, and generally cost less than other options. They are light and portable and can be used for a wide variety of purposes.
What are the types of impact wrenches?
Impact wrenches come in different types, but the three most common types of impact wrenches are the pneumatic impact wrench, electric impact wrench, and hydraulic impact wrench.
Let’s consider each of these types in more detail.
Pneumatic impact wrench
The pneumatic impact wrench is usually powered by compressed air. Therefore, to use this type of impact wrenches, you will require an air compressor.
They possess several advantages.
For one, these impact wrenches run on a steady supply of compressed air; therefore, they can be continuously used. They do not require any electric outlets or sources to function.
They are also usually smaller than other types of impact wrenches. Hence, if you are working in a confined space, you will find them super-effective.
Despite these advantages, these wrenches also come with problems.
A common drawback is that they lack adjustment mechanisms, hence you have to adjust the power. If your project requires a certain amount of torque, these wrenches can be problematic to use. Their lack of adjustment mechanism means that if the work requires minimal torque, the standard torque from the wrench can damage or even shatter the bolt.
Electric Impact Wrench
As the name implies, these wrenches run on electricity. There are often cordless, although a large number remain corded.
The corded electric impact wrench can be used for as long as you have a power source to plug it into. They do not need batteries, and since they have power regulators, adjusting the torque is not problematic.
However, the corded electric impact wrench lacks the portability than their cordless counterparts possess. If your cord is short, then you will have a limited area to work in.. furthermore, without electricity, they are utterly useless.
The cordless electric impact wrenches rely on batteries to function. They are highly portable and can be used anywhere. However, they lack the power for serious or heavy-duty projects.
Hydraulic Impact Wrench
This wrench is the most powerful impact wrench available. It is not meant for household or domestic projects but can be found applied in industrial conditions.
What factors should be considered when choosing an air impact wrench?
The following are vital factors to be considered.
Torque is what affects the rotational movement of your bolt. It is the power that influences the bolt or nut you are working on. The higher the torque, the faster and more powerful the impact wrench will be. Hence, you must consider the purpose you will be using the impact wrench for and the amount of torque required to accomplish the project easily.
2. RPM & IPM
RPM (revolution per minute) and IPM (impacts per minute) are vital factors that will affect your choice. The higher the RPM, the less effort it will take to unscrew or screw a bolt or nut. If you plan on finishing your work quickly, then you should choose an impact wrench with a high RPM. The IPM also serves in the same manner.
You have to consider the size and weight of the impact wrench before you make a purchase. A lightweight impact wrench will make your work easier and faster, without causing unnecessary strain on your wrists. Furthermore, if your project requires moving around, you might want to choose an impact wrench that is easy to carry around with you.
The size of the air impact wrench will affect the kind of use you will get from it. If you are planning to use it mainly for home use, a small impact wrench will be an excellent option. You should keep in mind that in most cases, the bigger the impact wrench is, the more powerful it is likely to be.
Choosing the right air impact wrench from the extensive collection of wrenches on the market can be quite a challenge. However, by considering this review and guide, you will be better equipped to make the right choice.
