Milwaukee M12 FUEL™ 3/8" Stubby Impact Wrench

I recently had the opportunity to put the Milwaukee M12 FUEL™ 3/8" Stubby Impact Wrench through its paces, and I have to say, it left quite an impression. As someone who frequently works on vehicles and various DIY projects, I've encountered my fair share of impact wrenches. This compact tool has managed to stand out for several reasons.

Design and Build Quality

The first thing that struck me was its compactness. Measuring just 4.8 inches in length, this tool is designed to fit into tight spaces where other wrenches would struggle. Despite its small size, it feels sturdy and well-constructed. The ergonomic design ensures that it sits comfortably in your hand, reducing fatigue during prolonged use. Its 2-pound weight further adds to its ease of use, making it a practical choice for extended projects.

Performance and Power

Don't let the size fool you—this little wrench packs a punch. With up to 250 ft-lbs of breakaway torque, it can tackle even the most stubborn bolts. I tested it on a variety of tasks, from removing lug nuts to dismantling suspension components, and it performed admirably in almost all scenarios. The 4-Mode Drive Control is a standout feature, offering versatility for different tasks. Modes 1 to 3 allow you to control the RPM, while Mode 4, the Auto Shut-Off, prevents over-tightening. This feature is particularly useful when reassembling parts, ensuring you don’t accidentally overdo it.

Battery Life and Charging

One of the aspects I appreciate most about Milwaukee tools is their battery technology, and the M12 Stubby is no exception. The tool is compatible with the M12 battery system, and it comes with both a 2.0 Ah and a larger 4.0 Ah battery. This dual-battery setup provides flexibility; the smaller battery is perfect for tight spaces, while the larger one offers extended runtime. During my tests, the batteries lasted impressively long, even under heavy use. The charger included in the kit is efficient, bringing a dead battery back to full charge in a reasonable time.

Versatility and Ease of Use

The compact design of the M12 Stubby makes it suitable for a wide range of applications. Whether you’re working under the hood of a car, inside a cramped engine bay, or tackling home improvement tasks, this tool adapts effortlessly. The built-in LED light is another thoughtful feature, illuminating dark workspaces without the need for an additional light source. The tool’s noise level is also notably lower than its pneumatic counterparts, making for a more pleasant working environment.

Limitations

While the M12 Stubby is an impressive tool, it’s not without its limitations. It struggled with extremely high-torque applications, such as breaking loose crank pulley bolts or heavily rusted suspension bolts. For these tasks, a more powerful impact wrench or a pneumatic tool might still be necessary. Additionally, the tool’s width can be a hindrance in exceptionally tight spaces, requiring the use of extension bars, which can reduce torque.

Practical Applications

I found the M12 Stubby particularly useful for automotive work. Changing tires, removing brake calipers, and working on suspension components are all tasks where this tool excels. Its compact size makes it easy to maneuver around a vehicle, and the various torque settings allow for precise control. It's also a great tool for farm maintenance tasks, such as driving lag bolts into dense wood, where an air wrench would be impractical.

Value for Money

Milwaukee tools are generally on the pricier side, and the M12 Stubby is no exception. However, the premium price is justified by the tool’s performance, build quality, and battery technology. If you’re already invested in the Milwaukee M12 ecosystem, this tool is a logical addition. Its versatility and reliability make it a worthwhile investment for both DIY enthusiasts and professional mechanics.

Conclusion

In summary, the Milwaukee M12 FUEL™ 3/8" Stubby Impact Wrench is a remarkable tool that offers a combination of power, compactness, and versatility. It excels in a variety of applications, from automotive repairs to general DIY projects. While it may not completely replace more powerful impact wrenches for certain high-torque tasks, it covers a broad spectrum of uses with ease.

Would I recommend this tool? Absolutely. Its compact design, powerful performance, and long battery life make it a valuable addition to any toolbox. Whether you’re a professional mechanic or a DIY enthusiast, the M12 Stubby is likely to become one of your go-to tools for a wide range of tasks.
