FAQs

How much CFM do I need for my impact wrench?

It all depends mainly on the size of the impact wrench you’re using. The bigger the impact wrench, the more the air you will need. Let’s check out the well-known impact wrench sizes available and the ideal cfm required.

1/4-inch

You don’t need much air pressure here. A 1-1.5 CFM is sufficient for a 1/4-inch wrench. Of course, you can go for more air, but it’s not necessary. Anything smaller would mean you won’t have enough power to operate this size impact wrench.

3/8-inch

For an impact wrench of this size, you will need a bit of more power. It would help if you had roughly the double of a 1/4-inch impact wrench. That means you are on the lookout for a 3 to 3.5 CFM air compressor. Is it safe to go lower?

Maybe. However, if you could get a 2.5 CFM air compressor, it will be cutting close to the limit. If you need a model specifically for a 3/8-inch impact wrench, the recommended rating is the 3 to 3.5 CFM.

1/2-inch

If you’re not new to the impact wrenches, you may be familiar with the 1/2-inch impact wrench. It’s probably the most common of all sizes, and in terms of sizing, they are in the middle of the chart. You must size its CFM right.

The good news is, there are many options to consider when it comes to the right CFM. Anything between 3.5 to a 5 CFM can be ideal for this size impact wrench. If you need to get specific, the best recommendation would be 4 CFM.

If you’re running a professional workshop that uses multiple 1/2-inch impact wrenches, the best CFM rating is 5 CFM. It will give you the ideal balance of everything you need to operate the wrench.

1-inch

Lastly, there is a 1-inch impact wrench. These types are uncommon and mostly found on construction sites only. Besides their sizes, you need a powerful air compressor to operate them, something with a 9 to 10 CFM range. And as you can guess, this size of air compressors are expensive. You’ll have to dig deeper into your pockets.

Can you convert psi to CFM?

PSI and CFM are two different units. It’s like talking about how to convert pressure into volume; they are not the same elements. What’s more, they have opposite effects on each other, and their relationship is linear. If you have 8 CFM at 120 PSI, you can get 4 CFM at 60 PSI.

How many CFM do I need for air tools?

Air tools are a broad name that is used to describe every equipment that needs air to operate. That means there those that need less CFM to perform optimally, and there those that need higher CFM for better productivity. With that said, most of the personal-use air tools will require anything between 0 and 5 CFM. For the more extensive air tools, mostly used by professionals, you need something above 10 CFM at 100 or 120 PSI.

Is it OK to hand-tighten lug nuts?

No. Yes, you need to install the wheel lugs by hand, but not to tighten them. Most manufacturers recommend using hands to push the wheel home on the right hub and use a socket wrench to tighten them to make sure they hold snugly. You should know that pulling the lug nuts with hand might allow them to get loose in the future and cause problems.
