What Customers Are Saying
Customers overwhelmingly praise this tool set for exceptional value, comprehensive coverage, and durable construction. Reviewers consistently describe the tools as top-quality and built to last, with solid ratchets, sockets, and wrenches that exceed expectations for the price. The extensive range of SAE and metric sockets, deep and standard options, and multiple drive sizes deliver versatility for diverse tasks. The well-organized storage case with color-coded labeling—red for SAE, blue for metric—enables quick identification and reduces errors. The lifetime warranty is cited as a decisive purchase factor, adding long-term confidence. A few note faint size markings on some sockets, but this minor issue does not diminish overall satisfaction. Most consider this set an outstanding value.

Would RecommendI got this tool set for my car and it was a life saver. Almost every tool you need to do minor repair to your car is included and easily stored in the included hard plastic case.
Don't like the laser etching on socket sizes
Would RecommendFirst the pros: 1.These sockets, ratchets and tools have great quality and finish, comparable with big name products. 2. Like the color markings to distinguish between metric and standard. 3. Moulded tool box has reinforced plastic hinges, with steel pins, for long life 4. Like the gear ratios on the ratchets for easy movement in tight places. 5. Wrenchs are stamped, instead of laser etched, to easily identify size. Cons: 1. Totally dislike the laser etching on sockets. It has no depth a...
Kobalt 138-piece tool set.
Would RecommendChose the Kobalt 138-piece tool set to use in my home shop and also to take to my Hunting Club cabin when i need tools up there. This is my first experience with Kobalt tools and overall I am happy with the quality and performance so far. This set contains 3 rachets (1/4", 3/8" and 1/2") drive and a total of 86 sockets in the 3 sizes (41 metric, 43 SAE and 2 spark plug 5/8" and 13/16"). The Ratchets are solidly built and the 90 tooth sprockets make for quick ratcheting action. The Sockets are co...
Good set of tools
Would RecommendI was desperately in need of a new socket set. This took care of that problem instantly. I like that it has both metric and standard sockets both shallow and deep for your needs. Also, I think Kobalt makes a good quality tool for the price. Just remember these are not for impact use, so don't get carried away when using these for your applications. It also has a small array of combination wrenches, which are nice if you don't have any or if you plan on extending your set with more individual pie...
Many very nice tools
Would RecommendIn this tool set there are plenty of tools for working on your cars and around the shop and home. The tools are very well made and well marked with clear acid etching on all the sockets. I’ll be recommending it to all my family and friends.
Kobalt takes the show!
Would RecommendWhat a fantastic set of SAE and MM tools all in one case. Sure it is heavy but it is much easier to carry than 2 separate sets. AND the sockets are all color coded, a blue ring for MM and a red ring for SAE. I have had a few socket sets in my life and I was used to chrome plating (40 years ago) being very poor or nearly non-existent in pockets like on the deep small sockets. The chrome is excellent all over and in every inside corner and edge. I was so impressed I used a magnifying glass to insp...
Solid tools with some caveats
Would Not RecommendThe good: The tools themselves appear to be very solid. The socket heads especially are clearly marked and there is a good selection of Metric and SAE sizes in both shallow and deep, and specialty spark plug sockets. Also good: a no-hassle lifetime warranty. Also good: a very reasonable price for so much steel. The curious: For all the tools in the case, including three ratchets, there is no simple-yet-useful spinner handle. Kobalt makes one, but they don't include it. Also curious: almost a...
organized and ready for any job
Would RecommendI am always running back and forth to the standup toolbox getting the size (or the wrong size) tool when working on car or lawnmower. Always wanted one of these super organized boxes with all the pieces in place. Why in the world I waited so long to get it I don't know!! This is exactly whats needed to save time for getting a job done! Also I realized how easy it is to carry it in the trunk of my car when traveling. My family and friends always have something needing repair and with this set I h...
Complete and Bulletproof
Would RecommendThis set appears complete and bulletproof. It contains all the standard and metric sockets, hex keys and smaller combo wrenched any handyman or DIYer would need. The color coded sockets (red and blue) are a great idea to easily identify standard and metric as well as organize. The chromed steel sockets seem bulletproof and tough. Time will tell. I like the ratchets as the teeth grip well with zero worry of slippage. The pouches holding the hex keys are cheap plastic. Both are already crack...
Good socket set
Would RecommendGreat set of tools would have rated 5 star but the plastic holders for the Allen wrenches were torn on arrival could use a better set of Allen wrench holders to avoid people taking back because of a pouch issue love the tools like the red and blue mark on tools to distinguish between metric and standard
Awesome socket set
Would RecommendYou get a lot in one package. Really well made and good quality. Comes with both sae and metric. I would definitely recommend these. On top of everything else these are lifetime warranty. I like the red and blue stripes differentiating metric and standard.
Great set of tools
Would RecommendYou can't beat the quality and warranty of a Kobalt product. This is a great selection of sockets, wrenches, hex key and bit sets. The ratchets have 90 tooth gearing that allow you to work in tighter spots. The range of sockets should cover most normal projects. I like that there is both 6 and 12 point sockets because sometimes you just need one or the other for stubborn bolts. The range of open/box end wrenches isn't as good but should still cover most normal projects. The only thing I don't li...
Nice tools, customer service sucks
Would Not RecommendOne of the plastic latches on the hard case broke. I contacted Kobalt inquiring about purchasing a replacement latch (this is the same latch that is used on most of the hard case sets, and could be replaced without replacing the whole case). I was told by the lady I spoke with that I could return the whole set along with the purchase receipt to get the set replaced. I told her these sets were purchased last year by my employer for use at work that I would not be able to get the receipt. She said...
Great set for a outstanding price
Would RecommendThis set is a must have for any beginner mechanics and technicians. I have used this thing to fix brakes, drive belts, a/c compressors, shocks and struts, and much more. Kobalt tools have the quality of Matco or Snap-On without the obscene price that you pay for Matco or Snap-On.

Would RecommendFeels great ! Highly recommend also in process of getting impct wrench buddy of mines has it !!! Ill tell you its worth it

Hi kenthetoolman, we are happy to hear you are so pleased with your 138-piece mechanic's tool set. Thanks for choosing Kobalt!

Excellent excellent excellent
Would RecommendBest part about this set? You get 6 and 12 point sockets in 1/4,3/8,&1/2 options. By far the fullest set of useful sockets I've had.
Outstanding bargain!
Just stopped into my local store and saw this set. Picked it up no question asked! Can never have too many tools!
Dear Phatspeed7x, thank you for your feedback and for choosing Kobalt!

WOW what a value
Would RecommendBought 2 yesterday on sale for less than $42 ea. after my military discount. Great finish. Fine tooth ratchets. Nice case/organizer. Great warranty. Great starter set for smaller jobs as wrenches and sockets are on the smallish side,
