Before You Buy What to Look for

When it comes to air ratchets, you need to place a keen eye on certain features and functionalities. This will allow you to better decide on a ratchet that meets your needs.

Weight and Size

You should always look into the weight and sizing of the air ratchets you want to invest in. Some people put more stress on portability features, whereas others want more comfort.

If you’re one who seeks portability, you would want an air ratchet that is not only compact in size but is also lightweight. This will allow you to easily carry it around in your toolbox without adding too much to the weight of the box.

On the other hand, when looking for comfort, it is a good idea to get a ratchet that comes with a long handle. This will extend your reach and also minimize the stress on your hands.


When we talk about the speed of a ratchet, we are essentially looking at how fast the motor spins. We measure the speed in terms of RPM. It is a common misconception to think the best air ratchet has the highest speed. That is not the case since the speed entirely depends on the kind of bolt you unscrew.

If you’re dealing with large bolts, high speeds will favor you more. In the case of smaller bolts, you need to be delicate with the turning motion, which can be obtained from ratchets of lower speed settings.

So make sure you consider what kind of bolts you unscrew on daily before you look into the speed settings.


Torque is the force that causes the rotation of the ratchet head. The higher the torque, the more power it has when unscrewing your bolts. When dealing with extremely tight bolts holding thick materials together, a high torque air ratchet is the way to go.

You should also know that the torque also depends on the speed and weight of the air ratchet. The heavier your air ratchet is, the more force it will exert on your bolts.

Once again, taking into account the intensity of your projects will allow you to adjust the range of torque better to suit your requirements.


This is a feature that differs from person to person. Some people have little to no issues with the noise made by the ratchet motor, whereas some find it extremely annoying.

The ideal air ratchet will produce a minimal vibration noise that ranges around 85-100 dB. This will ensure that you are completely focused on your project, as the noise can cause irritation.

However, it should be noted that quieter ratchets carry a heavier price tag than the regular ones. So make sure you take that into consideration.

How Does an Air Ratchet Work?

The air ratchet, unlike the hand ratchet, uses compressed air instead of manual labor to turn your screws. Its socket drive is connected to a pneumatic turbine that turns when air is pushed in.

When you press down on the trigger, the air is released into the inlet, which turns the turbines to generate torque. As the pressure of the atmosphere is much lower than that of compressed air, a constant air pressure runs through the ratchet.

This, in turn, creates a constant RPM. For the air to exit, there is an outlet at the end of the cycle.

Once the socket is connected to your bolt, you will be required to press the switch on the body of the ratchet. This allows you to alternate between clockwise and counter-clockwise movements. Always know which side your motor is spinning, or else it might slip out of the socket.

One thing you must remember is to hold the handle of the air ratchet firmly before pressing down on the trigger. There have been several accidents where the ratchet slips out due to the high air pressure. Also, there are several brands that provide rubber layering on the handles to increase friction and allow a firm grip.

Why Do You Need To Buy 3/8 Air Ratchet?

Any ⅜ air ratchet with standard accessories is a great addition to your workshop. While some people think that they can get away with using a hand ratchet for every purpose, we’re here to tell you that’s not the case.

Increased Efficiency

An air ratchet banks a lot of benefits that any workshop owner should reap. Not only does it boost productivity, but it also increases efficiency. Even with the lowest torque and RPM, an air ratchet will unscrew bolts faster than any hand ratchet in the market.

Offers The Right Torque

When using hand ratchets for low to medium torque bolts, there is a high chance of causing damage to the threads. This happens because the manual force we apply is different from person to person, and so, it is easy to over-torque the bolt.

Ultimately, the threads of the bolt can get damage which won’t secure your parts well enough.

Another risk you run from using hand ratchets with these bolts is that you can easily snap off the top. There have been numerous cases where too much torque causes the stud of the bolt to snap off. This tends to create more problems rather than solving them.

Reaches Tight Spaces

One of the major advantages of using air ratchets is their ability to get into tight spots to undo bolts. When working with engines and car parts, you will often need to unscrew bolts at awkward and tight angles.

In these cases, impact wrenches or hand ratchets won’t have enough space to move around. Therefore, you can only rely on the air ratchet to help solve your problems.

Air Ratchet Troubleshooting – Some Common Problem and Fix

When it comes to using any power tool, you are bound to experience performance deterioration after a certain period of time. If you use air ratchets for prolonged periods of time, a common list of problems will creep up on you soon enough.

Here are a few common problems with pointers to help you solve them.


Upon turning your air ratchet on, if you notice any bit of moisture, you need to get to the bottom of it. When left ignored, this can cause heavy damage to the insides of your ratchet, reducing its longevity and output quality.

Signs of moisture usually mean the air pressure tank has not been drained properly. The presence of water vapors inside the pressure tank will ultimately find their way into your ratchet. We suggest immediately draining the tank of any water particle inside with the use of the drain valve.

Slow Running

If you notice that you aren’t receiving the speed that was promised when you bought the air ratchet, then you must check it out. There are several different reasons that can cause your ratchet to run slower than usual.

First of all, check the connection of your air hose. Any gaps in connection with the air hose can cause you to lose a good amount of air pressure. This, in turn, will cause the pneumatic turbines to turn slower, resulting in slow speeds.

On the other hand, using the air ratchet in environments that carry large amounts of oil and dust can slow it down. The dust and oil particles will eventually build up around your ratchet head and its insides, causing a slight and gradual decrease in speed.

To rid yourself of this issue, we would advise you to clean your ratchet regularly using grease and other listed cleaning agents.

Frequently Asked Questions

What is the effect of pressure and flow of going from 3/8 to 1/4″ air line?

When moving from a ⅜ air hose to a ¼, you are likely to experience reductions in airflow and pressure. The ¼ air line will not be able to match the needs of your air ratchet as well as the ⅜ will.

How much torque does an air ratchet have?

This depends from model to model. Air ratchets have a wide range of torque variations; there is no fixed number.

Do air ratchets need impact sockets?

Yes, they do. Impact sockets are much thicker and harder than regular sockets as they have been heat-treated for prolonged longevity.

What oil do I use in my 3/8 air ratchet wrench?

It is always advised to use synthetic or mineral oils on your air ratchet as other kinds might cause it to slow down.

What is the best amount of teeth for a 3/8″ drive ratchet?

The more teeth your ratchet packs, the fewer turns it will take to unscrew your bolts. When using air ratchets, the teeth don’t matter as you are not spinning the ratchet handle.

How does a Carlyle ratchet work like Carlyle 3/8 ratchet?

A Carlyle ratchet will work the same way as most branded ratchets do. There is little to no difference in the inner mechanics of the ratchets.

What tooth is a standard 3/8 air ratchet?

72 tooth ratchets are most common in the market and quite favored by the population.

What size socket will fit with a 3/8 ratchet?

You need to use a 10-millimeter socket with your ⅜ ratchet.

Final Words

Deciding on the best 3/8 air ratchet for your needs can be a troublesome task and will often lead you to run back and forth between options. However, with a keen eye on the torque and weight, you should be able to make the right choice.
