How to Choose the Best Air Impact Wrench?
You just cannot randomly buy an impact wrench without considering the important things that you need it for. So here are few things to look for in order to get a perfect air impact wrench.
## Drive Size
First, you need to determine for what reason you want an impact wrench. These wrenches come with various drive sizes that range from ¼ to 1 inch.
Drive sizes that are smaller than ½ inch are ideal for light works as they provide a low amount of torque.
If you are looking for an impact wrench for repairing cars and normal household and garage works, getting a ½ inch impact wrench will do the trick regardless of how rusty the nuts are.
On the other hand, drive sizes greater than ½ inch are used for heavy-duty works. If you are looking for a wrench for heavy-vehicle repairing or industrial works, go for the one with drive size of greater than ½ inches.
The drive size will determine the types of work that you are able to accomplish with the wrench. If you need to deal with heavy-duty works, wisely choose the size. Note that, if you consider getting a wrench with a higher drive size, the tool will be heavier.
But you have no choice to go with a heavier one, if you have to use the tool for construction or industrial purpose, as you cannot compromise about the performance. Because a smaller drive size and a lightweight wrench will reduce the efficiency of your work.
If you need an impact wrench for personal or professional use, you can get a wrench with small drive size while balancing the weight.
## Torque and Speed
How much force the tool can exert on a bolt and how fast it can loosen or tighten largely depends on the torque and speed of an impact wrench. In case of dealing with stuck and rusty bolts, more torque is better.
However, not every bolt you will loosen will require the same amount of torque and speed. Therefore, make sure to get an impact wrench that has adjustable settings, dial or regulator. It will prevent you from overtightening bolts. Also, it will help you to control the compressed air go through bolts that don't need full torque.
On the other hand, impact wrenches of higher speed have lower torque. Speed is necessary if you regularly have to deal with stuck bolts. If this confuses you which one to go with, go for the one that delivers higher torque.
## Weight Dimensions
After you take care of the performance, now it's time to consider about comfortability. A heavier impact wrench will feel more tiring to hold for a prolonged time. It will cause fatigue and often it may also lead to accidents. Therefore, a lightweight wrench would be highly suggested to get in this case.
If your working requirements demand you to reach hard reaching areas, then you need to also consider about the dimensions of the wrench you are about to get.
Ultra-compact or wrenches with long barrel can reach bolts that bulky wrenches cannot. Pistol style construction inline wrenches also reaches to such areas easily.
## Noise Level
If you are looking for a silent impact wrench, unfortunately, you will not find any. These tools require you to wear ear protection headphones to some extent while using them.
Nonetheless, you have the option to pick one that makes relatively less noise compared to others. Most impact wrenches make noise level about 75-90dB. However, there are some that only make 10 dB of noise or even lower.
But such wrenches lack performance compared to a wrench that makes about 80 dB of noise or higher.
Air impact wrenches are not inexpensive tools. Therefore, you don’t want to replace one just after few months of usage. So, you need to take the build quality into consideration before making the final purchase.
Most of the manufacturers use reinforced housing material like Kevlar to build the body. Materials such as composite housing, titanium hammer, and steel wear plate are also used. Be sure to get an impact wrench that is made of sturdy materials if your working environment is rough to tools.
For utmost comfort while using an impact wrench, you should go for the one that has an ergonomic grip on its handle. Having such a grip will make you comfortable when you have to use it for a long time.
The most certain way to know whether a wrench is durable or not is to read through the customer review section. If there is anything wrong with the build, users will surely say something about the issue.
Types of Impact Wrenches
Impact wrenches are of mainly 4 types. Each one of them differs from one another in terms of how they are powered. Let’s have a basic understanding of these impact wrenches.
Air Impact Wrenches
These are the type of wrenches that we covered in the review section. They are powered by compressed air. Often, you will see people using these wrenches with a short hose and directly fitting the wrench's drive into the tool.
Most of the air wrenches come with a regulator that sets the direction and controls the torque speed. This is to prevent over tightening the bolts that may cause them to break.
Air impact wrenches are low in cost compared to other types and weigh low as well.
Fields of Using Air Impact Wrenches
These type of impact wrenches are very popular for their performance and power. As they are lightweight, people don’t feel that much fatigue compared to other types of wrenches. You will find air impact wrenches are being used in automotive shops, homes, garages, and few construction sites.
Electric Impact Wrenches
As far as the electric impact wrenches are concerned, they are of two types.
Corded-Electric Impact Wrenches does a decent job of tightening and loosening stuck, rusty, and toughest nuts and bolts. They provide a similar level of torque as air impact wrenches do. The only difference is, due to the cord, you have to operate it within the range that the cord can cover.
Cordless-Electric Impact Wrenches, on the other hand, are mainly battery powered ones. There is no restriction of range; you can use it anywhere you want. They are similar to the air impact wrenches in the case of ease of use. But they are not as powerful as the corded ones.
Fields of Using Electric Impact Wrenches
People use corded ones in their homes, garages, and automotive shops.
Cordless ones are used by the homeowners, drivers, auto mechanics.
Hydraulic Impact Wrenches
A hydraulic impact wrench is operated through water under pressure and delivers torque to fasten or loosen nuts and bolts. These wrenches are extremely powerful, even more than air wrenches. They are the most uncommon type of wrench.
Fields of Using Hydraulic Impact Wrenches
These tools are used for heavy-duty operations such as manufacturing, construction, massive installations, etc.
Manual Impact Wrenches
It is the most common type of impact wrench. A manual impact wrench is powered by the hand. It comes with a head technology that converts spring power in sharp tensional blows. While fitting directly to the socket, it blows several times when someone applies force to the handle.
Fields of Using Manual Impact Wrenches
The travelers rarely use such wrenches in their camping area.
How Does an Air Impact Wrench Work?
An air impact wrench is powered by compressed air. Every wrench has a rotating mass inside of them. When the compressed air powers the motor, it transfers energy to the rotating mass. The momentum of that mass then allows it to act as a hammer and applies force to an anvil while creating a torque force.
Then with the help of that torque force, the tool loosens or tightens nuts and bolts. Some air wrenches use twin-hammer mechanism to increase the amount and speed of torque.
While on the other hand, some wrenches use a clutch for providing more power and torque to the anvil.
Benefits of Using an Air Impact Wrench
No matter whether it’s tightening or loosening a bolt, you will get some advantages for using an air impact wrench. At the time of tightening, the tool allows you to control the torque amount precisely. It prevents the nuts and bolts of being overtightened, which is a common scenario when you use the hand.
In addition to that, it also prevents the threads from stripping out due to the excessive force exerted on its structure.
When it comes to loosening bolts, you can loosen any bolt no matter how hard it's stuck and how rusty the condition is. It will save your precious time and energy by loosening the bolts within a few seconds.
