Kobalt 20 -Piece Standard (SAE) and Metric Mechanics Tool Set with Hard Case with its. 90-Tooth ratcheting design provides 4 degrees of arc swing. 1/4-inch Drive Ratchet. I like the way the case is made, I can add extra extensions, swivel socket adapter in between the rows of sockets. The Socket are great, but the ratchet is junk, I replace it about five to six times, in the last twelve years, the last one I have I never even used because it’s lockup. And you can’t go in get just a new rat...
Missing SAE Size and Massive Box Wastes Space
This could be an awesome product, but it's been crippled by not having some socket sizes (one SAE in particular) and some useful socket drive accessories. The worst of it is a massive blow molded box with enormous wasted space that doesn't allow completing this set with additional sockets and drive accessories. What on Earth were those that designed this thinking? 1. Most glaring is the SAE side missing a 9/32" socket. Has 7/32" and 11/32" but they couldn't toss in another pocket somewhere with ...
Great Set!!
I’m a huge fan of Kobalt mechanics tools. They have all been very high quality from the case to the smallest socket. Made in Taiwan, and I know what you’re thinking. I’m a made in USA guy too, but if it is not made in USA, Taiwan has almost the same quality standards. This set is a 1/4 ratchet, which Kobalt recently upgraded to 90 teeth, and contains both metric and inch sockets. However, if you need anything above 1/2 or 10mm, look for a bigger piece set with a 3/8 ratchet and larger sizes....
This tool set arrived miss the 1/4in shallow socket 11/32in. This is the third 1/4in socket set that I’ve rec dived in then last two days with missing sockets. Is someone at your processing center taking the sockets for alternative use?

The packaging ruined the kit for my needs.
I have many sockets and sockets sets in the garage. I however wanted a smaller set I could keep in the house without going through all the sets in the garage and assembling with a ratchet and extension etc. This set looked like it would be filling that need. The issues isn't with the tools themselves which I found to be decent. It was that the box they are kept in holds the sockets so tight that I have get a screwdriver to put inside the socket a pry them out. (Look at the pics of the box interi...
Ratchet itself is junk
The sockets and extensions are fine, I've used the ratchet for a few years in a professional setting alongside ratchets of various quality, some better, not many worse. My biggest gripe is the switch. It's always been too easy to manipulate but as I've used it the switch has gotten more and more loose, almost always moving itself while I'm using it. It's obvious that this isn't a nice ratchet, especially because it's not a model you can buy separately. If you plan on using this tool with a...
Hi Ryan, thanks for taking the time to share your feedback. We are slowly updating the ratchets in all of our sets to the newest design as we move t...

Very Nice Case
This is a really handy tool set to add to my tool collection. The set includes a variety of 6-point sockets, from 5/32 inches to 10 mm-12mm, which easily fit on small to medium sized bolts. The compact ratchet makes this much more convenient to carry around especially with the nice and sturdy hard covered case that it comes with. Fits nicely in my tool bag and doesn't take up too much room. The double closure lock on the case (snaps closed at the top and bottom) gives me confidence that it won't...
Great for small jobs and keeping handy on the go
First off, I'm not a very handy person when it comes to tools. This Kobalt set has really proven to be helpful in the times I've used it. It has a nice sturdy box in order to keep the sockets all arranged neatly and nicely so they don't get loose and fall all over. The ratchet itself is really nice. It's a compact and easy to hold size, but has a nice weighted feel to it. I've used this for various jobs in the house and it's proven to be useful. The SAE and Metric sockets are a great snug fit on...
Cobalt 24-piece SAE and Metric Mechanic's Tool Set
I received this set yesterday. The finish was excellent, heavily chromed and the ratchet is 90 toothed and very smooth operating. The sockets are beautifully finished as well. I immediately compared it to my Kobalt 115 piece set I bought two years ago. The difference is daylight and dark. I have not liked my original 115 piece set from the beginning. The ratchets are 72 toothed, are rough ratcheting, lock up if you put too much pressure on them, and gum up easily and have to be cleaned with pene...
From 24 -Piece Standard (SAE) and Metric Mechanics Tool Set with Hard Case Lowe's Loop
Kobalt 1/4 Inch Drive Socket Set
The Case: Pros: The Plastic Case is very attractive and appealing to the eye. It appears to be very durable, hinge system utilizes metal in addition to the plastic, I would expect the hinge system to last much longer than other plastic cases that only utilize plastic as the hinge. Con: The case seems to be deeper that it needs to be and would take up less space if thinner. The Sockets: Pros: The color coding stripe is excellent to determine the difference between the MM and standard Socket...
