Air tool is a form of power tool, operated by compressed air with an air compression supply. Air tools also called Pneumatic tools can also be operated by compressed carbon dioxide (CO2) stored in small cylinders allowing for portability. 

Most pneumatic tools convert the compressed air to work using a rotating pneumatic motor.

With the wide array of Air Tools in the market today, choosing the best one can be a hard task. Nonetheless, we have simplified the job for you by reviewing some top best Air Tools for impact wrench, Impact Wrench Gun using Compressed Air.

What Can You Do with Impact Wrench?

In this reviews, you will get more than a glimpse of the best Reciprocating/sawzalls that will give you reliable performance.

How To Choose The Best Air tool For The Money

It is pretty easy to tell out the impact wrench theoretically. That is what I am doing presenting to you a theory of my practical experiments with the different impact wrenches and these are the factors that I use a measuring gauge.

Power, Budget, Comfort & more below...

Torque

First and foremost, you want a machine that can generate the kind of power that you need to get the job done. Since the primary function of this tool is turning power, it’s imperative that you measure its abilities based on the level of torque it produces.

For the most part, impact wrenches will generate anywhere from 300 to 1800 pounds of torque, but you don’t always need the highest number. Unless you are working with some truly tough bolts that need extra effort to tighten correctly, you should be okay with around 500-800 pounds.

Socket Size

To fully be able to use an impact wrench you need a set of sockets to go around the nuts and/or bolts. Thus, it’s critical that you pick a model that fits the kinds of sockets that you have so that they will be compatible. Usually, impact wrenches will be from ¼ inch to one full inch, with variations in between such as 3/8, ½, and ¾ inches.

There is not really any particular benefit to using a specific size, so pick the one that fits more than anything else. If you don’t currently have sockets, then just make sure that they are the same as your wrench.

Inline vs. Pistol

There are two primary configurations that your impact wrench can have, and each one will factor into the kind of work that you do. Inline models resemble a large screwdriver, with a grip that sits behind the motor and the hammer (the part that goes into the socket).

This type is ideal when you’re working in tight spaces and don’t have a lot of room in which to move. For example, working on cars or other vehicles may require an inline impact wrench since a pistol-grip won’t be able to fit.

Pistol wrenches are similar to a standard power drill, with a trigger system for activation. Unless you specifically need an inline model, we highly suggest that you choose a pistol wrench. The reason for this is that it’s much more ergonomic and puts less strain on your hand and wrist.

Size and Weight

Speaking of strain, one important factor to consider is the bulkiness of your impact wrench. Usually, these devices will weigh a couple of pounds, but that’s not including a battery pack. Also, if you are working at odd angles, a few pounds can feel like a hundred after a few minutes.

Size is also important as it will dictate what kind of spaces in which you can work. Cordless impact wrenches are already pretty versatile, but if it’s too bulky, then it might as well be a paperweight.

RPM and IPM

When looking at different impact wrenches, you’ll see some important numbers regarding its performance. The first is usually the rotations per minute (RPM), and it refers to how fast the hammer can spin. If you want to work faster and tighten bolts much more rapidly, then you want a higher rpm.

IPM refers to the number of impacts per minute, which is when the hammer strikes the anvil. Usually, this rating will be similar to the rpm because they are both required to get a tighter seal on your nuts and bolts. Again, the higher the rating, the faster you can work.

Also, if you have to loosen items that are really stuck, having a faster rpm and ipm can ensure that you won’t have any problems removing it.

Speed and Torque Adjustment

Not all jobs are the same, which means that if you have an impact wrench that only operates at one setting you may or may not be able to make it work across a variety of situations.

For the most part, you want to get a unit that enables you to adjust the speed setting so that you can work on a wider range of projects. This way, you are only using the right amount of power for the job, so you aren’t over or under doing it at any point.

Also, being able to change the torque is a huge benefit since you can adjust it to fit the specific needs of the nut or bolt you’re currently working on, rather than having it the same across the board.

How to Use an Air Compresses Impact Wrench

One of the most versatile tools in any garage is an impact wrench, considering that it can be used to tighten and loosen nuts and bolts of any size. However, if you’re new to this tool, then it’s important that you understand how to use it correctly.

Because impact wrenches are so powerful, it’s easy to go a little overboard with them, particularly when tightening. As such, you should follow these steps to ensure that you get the most out of your tool without doing any damage.

Step One: Air vs. Electric

For most professional shops, an air-powered impact wrench is a necessity because it allows them to work fast and efficiently. However, if you are just doing some light work in the home or your own garage, an electric unit is most likely an ideal choice.

When using an air impact wrench, you have to connect it to a compressor via a hose, which can add some significant cost to your bottom line. However, electric models are now cordless, meaning that you have a lot more freedom.

Step Two: Place the Socket

This tool will only work when you have a socket on the front to loosen or tighten the bolt, so it’s imperative that you have a full set from which to choose. Most wrenches are either ½ or ⅜ inches, so check to ensure that your sockets are compatible.

Step Three: Check the Direction

Impact wrenches can either move clockwise or counterclockwise, and it’s crucial that you know which way it’s moving before you start working. Pull the trigger to watch the direction of the spin, and adjust if necessary.

Step Four: Adjust the Settings

In some cases, you can customize the speed and torque of your impact wrench for better results. If your tool has that capability, then make sure that everything is optimized for the job at hand. As a rule, you will need higher torque when loosening than when tightening.

Mistakes to Avoid

As we mentioned, it’s common for beginners to overcompensate when using this kind of power tool because it almost makes things too easy. So here are some things to keep in mind.

● Don’t Over Tighten: when putting a nut or bolt on, pull the trigger in short bursts, and check the tightness as you go. Over time, you’ll learn how to feel when it’s tight enough, but until then double check.

● Don’t Damage the Threads: rather than trying to put the bolt in with the wrench, get it started by hand so that you know it will go in correctly. If you come in at the wrong angle with the tool, it could cause a lot of problems.

● Use the Right Socket: if it’s too loose, then you will have to work harder to get the job done, and you could strip the threads. Make sure that it fits properly each time you pull the trigger.

Overall, an impact wrench is a relatively simple tool, but don’t underestimate its capabilities. If necessary, practice a bit before you do the real job so that you can get a feel for how it operates.

How to Cut a Shape in the Middle of A piece of Material?

Make Your Line

Now that your blade and your saw is set up and adjusted, you want to once again make sure that you have drawn the line that you are going to cut along for your circle. If you want it to have a perfect circular curve, make sure that you use some kind of perfectly cylindrical object that you can draw around to make your line. If you want to use a different shape, use an object that has the shape and dimensions that you need.

Drill a Hole

Before you actually start cutting, you need to make sure that you drill a hole into the inside edge of the shape that you are about to cut. This will give you your access point of where you are going to insert your reciprocating saw.

Insert the Blade and Start Sawing

If you are cutting an object in the middle of the material you are using, you probably want to use a jigsaw blade. A jigsaw blade will give you the ability to cut the shapes and the angles that you need to cut. Trace your saw along the line that you just drew so that you get the perfect cut.

Changing Your Saw Blade

Different materials and sawing situations may require different kinds of blades. For instance, if you are cutting wood, you are going to need a different saw than if you are cutting through metal. To change the saw blade, all you will need is the blade itself and typically an Allen key to release the blade that’s already in your saw.
