Craftsman Metric Jumbo Combination Wrench Set

The Craftsman Metric Jumbo Combination Wrench Set (model CMMT12055) is a toolset that I've come to appreciate over the course of various projects. This 5-piece set, designed for metric measurements, encompasses sizes 23mm, 24mm, 25mm, 27mm, and 30mm, making it versatile enough for a range of applications from automotive repairs to more general bolt-turning tasks.

Design and Build Quality

First and foremost, the full polish chrome finish immediately stands out. Not only does it give the wrenches a sleek, professional look, but it also provides excellent corrosion resistance. This is particularly important for those of us who often work in environments where tools are exposed to moisture or other corrosive elements. The chrome finish makes it easier to clean the wrenches after use, ensuring they remain in good condition over the long term.

The build quality is solid, employing steel that feels robust and durable in hand. However, I did notice that these wrenches don't quite match the heft and finish of some older Craftsman tools I own. While this doesn't necessarily affect their performance, it's something to be aware of if you're accustomed to the vintage Craftsman quality.

Performance and Usability

One of the standout features of this set is the 12-point box end. This design allows for quicker engagement with fasteners, reducing the chance of rounding off edges, which is a common issue with lower-quality tools. The 15-degree box end offset is another thoughtful addition, providing additional knuckle clearance. This becomes especially useful in tight spaces where maneuverability is limited.

I found the large size markings to be incredibly helpful. When you're in the middle of a project, the last thing you want is to waste time squinting at tiny numbers or trying multiple wrenches to find the right size. The clear, large markings on these wrenches eliminate that hassle, allowing for quick and easy identification.

Practical Application

In practical use, these wrenches perform admirably. I've used them on various projects, including working on large rock drills and performing emergency repairs while off-roading. They provide a secure grip on fasteners, and the 12-point design significantly reduces slippage. The wrenches are long enough to offer good leverage, making it easier to loosen or tighten bolts without exerting excessive force.

That said, there are a couple of aspects that I wish were different. The set skips several sizes, which can be a bit inconvenient depending on the range of fasteners you encounter. Additionally, while the build quality is generally good, it doesn't quite live up to the high standards set by older Craftsman tools. These newer models feel a bit more lightweight and less refined, though this doesn't seem to impact their overall functionality.

Warranty and Value

One of the most reassuring aspects of this set is the full lifetime warranty. Craftsman has long been known for standing behind their products, and this set is no exception. Should any of the wrenches fail or break, you know you can get a replacement with minimal hassle. This "buy once" approach is particularly appealing for those who want to invest in tools that will last a lifetime.

In terms of value, this wrench set is competitively priced. While it may not have the same premium feel as some older Craftsman tools, it offers excellent functionality and durability for the cost. Whether you're a professional mechanic or a DIY enthusiast, this set provides the essential features you need without breaking the bank.

Final Thoughts

Overall, the Craftsman Metric Jumbo Combination Wrench Set is a solid addition to any tool collection. It combines essential features like corrosion resistance, quick fastener engagement, and a lifetime warranty, making it a reliable choice for a variety of tasks. While it may not entirely match the build quality of older Craftsman tools, it still performs well and offers good value for the price.

Would I recommend this tool? Absolutely. Its practical design, ease of use, and lifetime warranty make it a worthwhile investment for anyone in need of a reliable set of metric wrenches. Whether you're tackling automotive repairs, industrial applications, or just general maintenance tasks, this set is up to the challenge. The minor drawbacks, such as the skipped sizes and slightly less robust build, are outweighed by the overall functionality and value it provides.
