What Customers Are Saying
The Kobalt 20-Piece Ratchet Wrench Set offers a mixed performance. Many users praise its quality, smooth operation, and usefulness in tight spaces, describing it as a great value. However, some report quality control issues, with wrenches breaking or malfunctioning during normal use. While suitable as an affordable, general-purpose set, those requiring a reliable, heavy-duty option may want to consider other premium brands.

Was searching for reversible 15 degree angle ratcheting wrenches when I came across these. I've had one kobalt measuring tape go wrong on me (easy exchange no questions asked) otherwise I'm picky about my kobalt products as some are not as durable of a material (pliers and cutters longevity etc...) but! These are great. QC is obviously not as good on these as say.... snap-on... BUT! These are essentially costing what one or MAYBE two snap on standard non-ratcheting wrenches would cost. You simpl...
Great wrench set!
I bought these for a project I was working on that required a lot of disassembly and reassemble after parts replacement. These wrenches are well constructed and sturdy. I bought the SAE and Metric set because I plan to use them for a long time and on multiple projects which contain both types of nuts and bolts. I particularly wanted toe ratcheting box end because I typically come across many nuts which are in tight places and using an open end wrench is both time and labor intensive. The ratchet...

Good For The Most Part If You Don't Mind Rust.
I bought these for use on repairing our motorcycles. There are some places that are just too small for a socket to get in to and these are perfect. Well, 18 of them are perfect. Two of them, the 9/16" and 5/8" are rusting and the chrome is flaking off after less than a handful of uses in 3 months. These are garage-kept in a tool chest and cared for like my other Craftsman and Matco tools, some of which I've had for over 20 years without issue. I'm perplexed. I'm off to Lowes today to see how t...

Poor Quality Control
A couple of the wrenches in the set did not properly ratchet out the box. I went to my local Lowes to attempt to exchange the defective wrenches under the lifetime warranty. Several of the wrench sizes in this set are not sold in the store. The tool associate refused to open a new set to pull the sizes I needed or exchange the entire set under warranty. This is a poor product and bad customer service. I have many Kobalt tools, but I will not be buying any more since the lifetime warranty is wor...
Nice wrench set
I've been wanting to buy new wrenches to replace my decades old craftsman wrenches. My first choice was to get the Kobalt 180° pivot on the box end set, but didn't have the extra money to spend. This set for the price was just too good to pass up. I bought it for a fraction of what one set of the pivot style costs. I started taking things apart and fixing them just because I was excited to have them and let me tell you, they work great. I'm very happy with my purchase and if it should somehow br...
Hi Curt, thank you for your feedback! We appreciate it and your support of the Kobalt brand!

Use them Atleast once a week
I found a few sets of these on sale near the plumbing aisles at my local Lowe’s and wondered why they were by themselves. I was hesitant at first but kobalt has never let me down so I picked one set up. I was pleasantly surprised when I got home and saw how good the quality was. I use them at home for projects mostly related to my trucks or equipment. The only cons I see is that the ratcheting mechanism cannot be reversed. The wrench must be turned around in order to reverse the direction you wa...

Seems like a "light duty" set of wrenches
[This review was collected as part of a promotion.] Bought a set of these on Black Friday as a backup to my Craftsman set and I needed a set of metric anyway. Used the 10mm for a project and after a few successful bolts, noticed that when using the ratcheting mechanism would "hang up" on return stroke. The hole was pre-drilled and not a lot of torque used, it was however a long bolt and required many turns. Not expected with a new set, may just be a one off defect, I will be returning wrench for...

I like that these have 90 teeth instead of the typical 72 for working in tight spaces. They aren't reversible which means they also don't have angled box heads. Can't have both; decide which is more important. My set had one of the 12 point rings missing which meant a trip back for a replacement set. And it was a good thing they had a replacement in stock because they replace by return and re-purchase (for same amount) and their system said I paid $49 rather than $69. So I got a $49 refund and p...

This is good information to share! Please also note that you can call 1-888-3KOBALT (356-2258), choose option 2, then option 2 again to reach a cust...

Plastic is used to retain the ratchet.
Fit and finish is fine, the ratcheting mechanism is held in the ratchet by a plastic ring any perpendicular load will crack that plastic and render the wratchet. there's no lubricant in the reaching mechanism so that will ware out over time. the marking stripe for metric and standard are cool but break clean will take that right off. I've used husky and they do not have this fundamental flaw in its design at around the same price point.
We would be more than happy to replace the broken wrench. You can do so by reaching out to our customer service department at 888-3KOBALT (356-2258)...

A gift I wish I would have gotten.
My wife said that we had to get my brother-in-law a set of wrenches for Christmas. Well I was given the task of finding a good set of wrenches for him, since I do most of the mechanic work in both of our families. I shop at Lowes for a lot of my own tools and when I saw this set, I told myself, if I was getting tools this would be what I would want. I bought these and showed them to my wife and said "if he doesn't like these, I'll be happy to take them. Wish I had a set." Hoping my wife woul...
