Craftsman Cordless 1/2-in Impact Wrench Kit

Craftsman has long been a respected name in the tool industry, and their Cordless 1/2-in Impact Wrench Kit, model CMCF900M1, is a testament to their commitment to quality and innovation. As someone who frequently tackles a variety of DIY projects and automotive repairs, I was eager to see how this impact wrench would perform in real-world scenarios.

The first thing that struck me about this tool is its robust build and solid feel. Weighing in at 8.6 pounds, it’s certainly not the lightest impact wrench on the market, but the weight lends it a sense of durability and sturdiness that is often missing in lighter models. The ergonomics are well thought out, with a comfortable grip that makes it easier to handle during extended use.

One of the standout features is the variable speed trigger, which offers precise control over the tool’s 1,700 RPM maximum speed. This is particularly useful when working on delicate tasks where you don’t want to apply too much force too quickly. The ability to modulate speed with the trigger adds a layer of finesse that can be crucial for certain jobs.

The tool's maximum torque of 350 ft-lbs is a key selling point, and in most of my tests, it performed admirably. It effortlessly removed lug nuts torqued to around 100-120 ft-lbs, which is typical for many vehicles. However, I did notice that it struggled a bit with bolts torqued above 150 ft-lbs, particularly those that had been on for an extended period and were potentially rusted or corroded. This suggests that while the impact wrench is powerful, it might not fully live up to the 350 ft-lbs claim in all situations, especially for heavy-duty automotive work.

The hog ring anvil is a nice addition, making socket changes quick and hassle-free. This is an often overlooked feature, but it significantly improves the workflow, especially when switching between different sizes frequently. The LED light is another thoughtful inclusion, providing much-needed illumination in dark or poorly lit work areas. It’s a small feature, but one that enhances the overall user experience.

Battery life is another area where the Craftsman impact wrench excels. The 20V MAX Lithium-Ion battery with 4.0Ah capacity offers impressive longevity. During my testing, the battery lasted through multiple tire changes and a few additional tasks without needing a recharge. When it did come time to recharge, the fast charger included in the kit had the battery back up to full power in a reasonable amount of time. This efficiency is crucial for maintaining productivity, especially on larger projects.

Despite these positives, there are a few areas where the tool could be improved. The weight, while contributing to its durability, can become cumbersome during prolonged use. This is especially noticeable when working in tight or awkward spaces where maneuverability is key. Additionally, while the variable speed trigger is excellent for control, I found that it could benefit from a torque adjustment feature. This would provide even more precision, particularly when working with different types of fasteners and materials.

Another point worth mentioning is the motor type. The Craftsman CMCF900M1 uses a brushed motor, which, while reliable, is generally less efficient and durable compared to brushless motors found in some competing models. A brushless motor could potentially offer better performance and longevity, making this tool an even more compelling option.

One of the most compelling aspects of this impact wrench is the warranty. Craftsman offers a three-year limited warranty on both the wrench and the battery, which provides peace of mind. For those who want even more security, an extended warranty can be purchased to cover up to five years. This level of warranty support is a testament to Craftsman’s confidence in their product and adds significant value to the purchase.

In conclusion, the Craftsman Cordless 1/2-in Impact Wrench Kit is a solid performer with a lot to offer. It combines power, control, and convenience in a package that is well-suited for a variety of tasks. While it may not quite reach the 350 ft-lbs torque claim in all situations, it still provides more than enough power for most DIY and automotive applications. The excellent battery life, ease of use, and robust warranty make it a worthwhile investment for both hobbyists and professionals alike.

If you’re in the market for a reliable and versatile cordless impact wrench, the Craftsman CMCF900M1 is certainly worth considering. It may not be the absolute top of the line in terms of raw power, but its balance of features, build quality, and support make it a strong contender in its category.
