What is a impact wrench?
This is an automatic tool that specialized mechanics can use, assistants and enthusiasts at home. It is mainly used to tighten and unscrew bolts and nuts, remove car wheels, buses, trucks, etc.
With a pneumatic or electric impact wrench, you can unscrew even the tightest nuts. This machine is not so difficult to use, but it is desirable to follow specific rules for your safety.
Its main function is to save time and effort compared to conventional hand tools.
Advantages of using an impact wrench
One of the biggest advantages of the impact wrench lies in the time and effort you can save by using it. This is something you should keep in mind when buying it, as it is a tool that you should use to the maximum.
If you have repetitive tasks of disassembling parts or machines and do them consistently, this tool is perfect for you. It is claimed that the impact wrench saves up to 75% execution time and up to 90% less physical effort.
Of course, these differences will be even greater when you reject more work. For example, at the industrial level, there are tasks that involve disassembling machines with more than a thousand screws, which with this tool can be done by one person in a few hours.
Without it, more people will have to do the same task if it is to be completed in one day.
Sometimes there are stubborn screws that are almost impossible to unscrew with a wrench, and with the impact wrench, you will quickly deal with them.
Types of impact wrenches
They are divided according to the energy they are supplied with. Depending on the work you want to do, you can choose between a pneumatic, electric or cordless wrench.
Air impact wrench
Powered by an air compressor, this wrench is expensive and very efficient and durable. It is one of the most powerful to use, as it is ideally suited for intensive and demanding work.
Keep in mind that the use of earplugs is essential because this tool makes a lot of noise. It is mostly used on an industrial level in garages and vulcanizers.
It is known as electric because it uses AC voltage and needs a socket to be used. This type is the cheapest, and very often, consumers use it in their homes to perform non-professional tasks.
It is not as powerful as the pneumatic one, but at the same time, it is stronger than the battery one.
A cordless screwdriver similar to a cordless screwdriver is great for working on the go but not powerful enough or strong enough to work for long periods. Still, you can find models on the market with pretty good autonomy and power.
It’s generally more expensive, but it’s still the most convenient of all, and with each update, it improves battery life and the power it delivers.
How to choose the right impact wrench for you?
There is a wide variety of different models on the market. If you are not sure which one to choose, we will discuss all the aspects you need to consider to choose the model that best suits your needs.
In this little guide, you will be able to find out what tips we give you so you can find the right product and save money.
Impact wrenches are very powerful, so care must be taken during use to avoid breaking bolts and harmful materials.
Power is expressed in torque and is one of the main considerations when choosing an impact wrench. Torque is measured in Newton meters (Nm). The bigger the number, the bigger the power. Impact wrenches have power in the range of 100 to 1000 Nm.
These tools have an additional function when loosening nuts. They have a special way of hitting, wich brings extra power to loosen very tight parts.
When you choose a percussion wrench with good speed, you will find that 3000 rpm and more is enough. As already mentioned, the operation of impact wrenches is based on turning to tighten or loosen fasteners. More turns means less effort on the part of the user, as the impact absorbs the extra speed of work.
Lower speeds can slow down a task, so if speed is a requirement for your job, it’s a good idea to choose a model that puts a high priority on speed, even if you need to choose a model with less torque or beats per minute. .
Number of strokes per minute
The number of strokes per minute, as well as the speed, must be high enough, as the tool needs them to act on the fastener to tighten or loosen it.
If your budget doesn’t allow you to buy a tool with a large number of strokes per minute, look for one that provides a good balance between torque, speed and strokes per minute and your budget. If the first two are very good values, then you may not need too many beats per minute.
If the machine has significant torque and speed values, it will have the characteristics of an almost perfect impact wrench.
Many people think that the larger the size of the insert socket, the better the performance of the impact wrench, but this is not always the case. For example, would you use a 1-inch wrench to loosen 10 mm bolts daily? Certainly the answer is no. That is why it is important to take into account the size of the nuts, bolts and screws that you will use regularly, and accordingly choose a model with this size that is compatible with the inserts that you will use.
Impact wrenches designed for light to moderate use are available in three basic socket sizes: 1/4″, 1/2″ and 3/8″. The most powerful for very heavy work (for example, removing the nuts on the wheels of a car, bus or truck) are 1/2 “, 3/4” and 1 “.
In conclusion, good manufacturers will provide you with everything you need for the impact wrench you decide to buy and use, like most products on the market. Well-known brands offer models with all the privileges and experience to experiment with different designs and upgrades. They provide a good warranty, spare parts and after-sales service.
