This Kobalt combo kit is a must-have for anyone looking for a versatile set of industrial hand tools. Based on our own experience we found THE 12 point standard combination wrenches to be exceptionally durable, withstanding even the toughest jobs.The set also includes a range of sizes, making it easy to find the right tool for the job. However, we did find that the case is a bit bulky and can be difficult to transport. Overall, this is a great addition to any industrial and scientific toolkit..
