Things to Consider When Buying Air Impact Wrenches

Different Kinds of Impact Wrenches: Corded, Cordless, and Air

There are three different kinds of impact wrenches. These are namely air, corded, and cordless impact wrenches. Their main difference is mainly the power source, but they all have their advantages and disadvantages. Let’s have a look at them:

Corded Impact Wrenches

As the name implies, its power source is from an electrical outlet. These are significantly bulkier since they have a motor. They are also less compact due to the existence of a cord, so your movement becomes more limited.

In a way, corded impact wrenches have an advantage when it comes to a power source. It is quite rare that you find yourself in a situation without electricity if you’re working on home projects. Electricity as its power supply makes it reliable and convenient in that aspect.

However, if your supply runs out or you’re somewhere that doesn’t have ready access to electricity, you’re out of luck. An instance might be if your tire goes flat in the middle of nowhere and you have to change it. Corded ones become useless in this regard.

Cordless Impact Wrenches

These are a bit more compact since it doesn’t have a wire for you to trip over and get in the way of your work. However, they are heavier because lithium-ion batteries power them. They are also the pricier option among the three.

Though the batteries are rechargeable, allowing you to take them anywhere, the power may easily too. It poses a problem when it comes to the overall reliability of the tool.

Furthermore, they are also weaker than air impact wrenches. The price you pay for portability might not be worth it if you’re looking for a stronger, more versatile tool. Because they’re weaker, they’re better for more delicate work compared to other wrenches. You don’t run the risk of stripping fasteners.

With that, let’s get to discussing air impact wrenches.

Advantages of air impact wrench: Why should I buy one?

Air impact wrenches provide some advantages that will make your projects easier and more enjoyable. They let you do things that would typically be harder to do by hand. Because an air compressor powers it, it’ll surely be less physically straining on your part.

You can remove and install fasteners faster.

Time is always of the essence. You don’t want to spend extended periods of time stressing over that one grip that just won’t budge. Not only is it physically taxing, but it’s also mentally exhausting. An impact wrench will help you get these fasteners out in a jiffy.

It is the same when it comes to installing fasteners. Attaching them by hand takes a lot of time as opposed to doing it with an impact wrench. Tasks like these become less daunting and more fun if you can accomplish them in a snap.

Imagine how most impact wrenches have an average speed of 8,000 rpm or revolutions per minute. Your hand can’t exactly turn a conventional wrench that fast, now can it? This speed translates into the time you save attaching and removing fasteners.

You can install fasteners more securely.

If you’re working on large objects such as shelves, beds, or other large pieces of furniture, it should be sturdy. Sloppily attached fasteners can cause the furniture to fall, destroying your belongings and also potentially hurting others.

You can also use impact wrenches to secure lug nuts on wheels, or things that have engines like lawnmowers. These move around a lot so it’s of utmost importance that it’s tightly secured in place. It could cause serious injury if it isn’t.

Impact wrenches have incredible torque power, so rest assured that when you install something with one, it can run for life. It’ll be tightly secured – tighter than anything you can do manually. Just be careful not to overtighten as it could strip or damage the fasteners.

It’s compact and portable.

When compared to an electric impact wrench, the air impact wrench is definitely lighter and more compact. Electric impact wrenches have a motor which adds to its bulkiness while air impacts are operated through compressed air. Plus, the existence of a motor makes it more susceptible to damage.

The compact size makes it easier to reach small spaces so you can use it wherever you need to. It’s also not that hard to take around because it doesn’t take up as much storage space.

It’s cheaper than an electric impact wrench.

As mentioned above, electric impact wrenches have a motor included which makes it costlier. Furthermore, when they get damaged, it costs more to repair them. Air impact wrenches are easier to maintain because of how few their parts are.

The power source is cheaper and more reliable.

Air impact wrenches rely on compressed air, unlike electric counterparts that depend on electricity. When the power goes off, no one can tell that you are incapable of working. That’s the right thing about compressed air; it’s dependable. Furthermore, it’s cheaper to use than electricity.
