Craftsman 6mm 72 Tooth 12 Point Metric Ratcheting Wrench Review
Navigating the world of hand tools can be a bit of a maze, especially when it comes to finding that perfect ratcheting wrench to add to your collection. As someone who spends a significant amount of time tinkering and working with various mechanical projects, I’m always on the lookout for reliable, high-quality tools. Recently, I got my hands on the Craftsman 6mm 72 Tooth 12 Point Metric Ratcheting Wrench (model CMMT39240), and after putting it through its paces, I’m ready to share my thoughts.
To start with, the Craftsman wrench exudes the kind of build quality Craftman is known for. The full polish chrome finish is not just for aesthetics; it serves a practical purpose by providing excellent resistance against corrosion and wear. This might seem like a minor detail, but in the long run, it’s a godsend. Tools left exposed to the elements or even just the humidity of a poorly ventilated garage can start to degrade surprisingly fast. With this wrench, that’s one less thing to worry about.
One of the standout features of this wrench is its 12-point box end. This design allows for quick engagement with fasteners, which is particularly handy when dealing with stubborn bolts or nuts. I found it to be a real time-saver, especially when working in environments where every second counts, such as auto repairs. The 72-tooth ratcheting mechanism allows for smooth and efficient operation, requiring just a 5-degree arc swing to engage the next tooth. This is incredibly useful in tight spaces where a full swing isn't possible.
Another thoughtful design element is the 15-degree box end offset. This provides additional knuckle clearance, which can help prevent those frustrating instances where you end up scraping your knuckles against a hard surface. This small angle makes a significant difference in comfort and usability, especially when working in awkward positions.
The wrench is also well-marked with large, easy-to-read size markings. This might seem like a small detail, but it’s immensely helpful when you’re in the middle of a job and need to quickly identify the right tool. Not having to squint or guess at the wrench size saves both time and frustration, especially if you're working in low-light conditions.
In terms of performance, the Craftsman ratcheting wrench delivers as expected. It feels solid in hand, with a comfortable weight that balances durability with ease of use. The ratcheting mechanism is smooth, with no noticeable play or hesitation, which is critical for maintaining efficiency and precision during work.
While this wrench excels in many areas, it’s not without its minor drawbacks. The most notable is the amount of room required to turn the ratchet. It demands a bit more space compared to some other brands, like GearWrench, which may only need an 1/8th of an inch to engage the next tooth. This extra space requirement can be a bit limiting in extremely tight spots, but for most applications, it’s a minor inconvenience rather than a deal-breaker.
I primarily used this wrench for automotive work, specifically for removing and installing bolts during engine maintenance. It performed admirably, handling everything I threw at it without any signs of wear or reduced performance. The convenience of having a reliable ratcheting wrench meant I could often skip the socket set, speeding up the process considerably. This tool has earned its place in my toolbox, simplifying and streamlining various repair tasks.
One of the significant advantages of Craftsman tools is their full lifetime warranty. It’s a testament to the confidence the brand has in its products, and it adds peace of mind knowing that if something goes wrong, you’re covered. This kind of customer support is invaluable, especially for those who rely heavily on their tools for professional or frequent personal use.
In conclusion, the Craftsman 6mm 72 Tooth 12 Point Metric Ratcheting Wrench is a robust, high-quality tool that performs well across various tasks. Its durable construction, efficient ratcheting mechanism, and user-friendly design elements make it a worthwhile addition to any toolkit. While it does require a bit more room to operate compared to some other brands, this is a minor trade-off for the overall reliability and performance it offers.
I would definitely recommend this wrench to both professional mechanics and DIY enthusiasts. Its combination of durability, functionality, and ease of use provides great value, making it a solid investment for anyone in need of a reliable ratcheting wrench.
