Chicago Pneumatic is a synonymous name with impact tools especially pneumatic air and electric impact tools. Do not confuse this iconic American company with Chicago Electric. The latter is a generic tool company who makes entry level midrange tools in China.The 3/8 inch impact sockets are very good quality and comes in a nice sturdy plastic storage box. The size is metric meaning mm and has a good range across various sizes. It does skip some sizes but nothing unsusual. The size markers on the sockets are very easy to read and comes in real handy while finding the right size.I am giving one star less as the seller mentioned the model as SS3113D whereas the actual model is SS3113. The D stands for Deep meaning deep impact socket whereas the model I received was the shallow impact sockets i.e. SS3113.Nevertheless it is a nice product and will last a lifetime.P.S. For those interested this isn't a Made in USA set, it is Made in Taiwan. But quality is uncompromised and very well made.

There is no connecting extention road

As the other reviewer, I love CP tools. Their quality does not match their price. These are priced about what bottom barrel Chinese imports are priced at, but their quality matches the best out there. All of my new air tools are CP, and any future purchases will also be CP. I have broken sockets from every top manufacturer, Snap On, Mac, SK. It's just part of the game. These have held up so far, and they're priced much nicer. I just wish there was a 24mm in the set. It seems a lot of companies leave out the 24mm for some reason. I've never needed a 26 or 27mm, but I've used a 24mm plenty. I'll probably just buy a 24 and put it where the 26 lives.

I went through couple of projects with these sockets. For the price I paid, I am very impressed with this socket sets. I did remove the tools from the case and reorganized it into the tool box (The case was not very space friendly Sockets are not made in U.S - if this is important to you. But is strong enough for my 130ft/lb impact wrench.

Great product

They're nice, they complement other Chicago Pneumatic sockets I have. I don't know when I'll uses the 7mm but it's there. The sockets could have a little deeper recess on the smaller sizes to get into things better. They sacrificed depth and access for strength. They are impact sockets so that's why there's a trade off.

Quality tool. Perfect for 1/2 impact wrench on automotive brake projects.
