Craftsman Cordless Brushless 3/8-in Impact Wrench

The Craftsman Cordless Brushless 3/8-in Impact Wrench, model CMCF910B, has quickly become a staple in my toolkit. With its robust design and impressive torque, it offers an excellent balance between power and portability, perfect for a variety of tasks that require a bit more muscle than a standard drill.

Design and Build Quality

One of the first things I noticed about this impact wrench is its compact and lightweight design. Weighing in at just 2.4 pounds, it's easy to handle for extended periods without causing fatigue. The dimensions—7.7 inches in height, 8.5 inches in length, and 3.0 inches in width—make it small enough to fit into tighter spaces where larger wrenches might struggle. This is particularly useful when working on automotive projects or assembling furniture in cramped quarters.

The brushless motor is another highlight. Not only does it contribute to the tool's longevity, but it also provides a more efficient power delivery, ensuring that the impact wrench maintains consistent performance throughout its use. The build quality feels sturdy and durable, which is something I’ve come to expect from Craftsman tools.

Performance

When it comes to performance, the Craftsman 3/8-in Impact Wrench does not disappoint. It boasts a maximum torque of 165 ft-lbs, which is more than sufficient for removing large fasteners. During my time using it, I found that it handled everything from lug nuts to stubborn bolts with ease. The variable speed trigger is a fantastic feature, allowing for precise control over the torque application. This is particularly beneficial when dealing with delicate tasks that require a gentler touch.

I put this tool to the test on a variety of projects, including assembling a folding trailer kit. The impact wrench performed admirably, maintaining consistent power over several hours of continuous use. The hog ring anvil makes socket changes quick and straightforward, although I did encounter a minor issue with the retaining clip. It came loose a couple of times, which was a bit frustrating. However, this was a minor inconvenience in the grand scheme of things and didn’t detract significantly from the overall performance.

Battery Life

It's important to note that the battery and charger are sold separately, which might be a downside for some users. However, if you already own other Craftsman 20V MAX tools, you can use the same batteries, which is a convenient feature. The battery life is commendable, providing ample runtime for most tasks. I found that a single charge was more than enough for a full day’s work, making it a reliable companion for extended projects.

Additional Features

The built-in LED work light is a thoughtful addition. It provides adequate illumination in dimly lit areas, which is particularly useful when working under vehicles or in poorly lit garages. The light is bright enough to see what you're doing without being blinding, striking a good balance between functionality and comfort.

Ergonomics

Ergonomically, this impact wrench is well-designed. The handle is comfortable to grip, and the weight distribution is balanced, reducing the strain on your wrist and arm during prolonged use. The variable speed trigger is responsive and easy to control, allowing for smooth operation throughout the task.

Value for Money

Given its features and performance, the Craftsman 3/8-in Impact Wrench offers excellent value for money. It’s priced competitively, making it an accessible option for both DIY enthusiasts and professional tradespeople. The three-year limited warranty provides additional peace of mind, ensuring that you’re covered in case of any manufacturing defects or issues.

Conclusion

In conclusion, the Craftsman Cordless Brushless 3/8-in Impact Wrench is a versatile and reliable tool that excels in both performance and design. Its compact size, powerful torque, and user-friendly features make it an indispensable addition to any toolbox. While the issue with the retaining clip is a minor drawback, it doesn’t overshadow the overall quality and functionality of the tool.

I would highly recommend this impact wrench to anyone in need of a robust, portable, and efficient tool for various fastening and unfastening tasks. Whether you're a seasoned professional or a weekend warrior, this impact wrench is sure to meet your needs and exceed your expectations.
