The Milwaukee M18 FUEL is engineered for compactness, measuring just 4.8 inches in length, making it ideal for accessing tight spaces. It features a tri-LED lighting system that enhances visibility and reduces shadows, which is particularly useful in dimly lit work areas. On the other hand, the Protmex offers a more traditional design with a robust build and a half-inch drive, providing higher torque capabilities up to 1107 ft-lbs. While the Milwaukee focuses on compactness, the Protmex emphasizes durability and power, suitable for a broader range of applications.
Performance and Torque
In terms of performance, the Milwaukee M18 FUEL delivers up to 250 ft-lbs of nut-busting torque, making it effective for various fastening tasks. Its POWERSTATE Brushless motor ensures efficient operation, even in confined spaces. Conversely, the Protmex boasts a maximum torque of 1107 ft-lbs (1500 Nm) and offers three speed modes (up to 2300 RPM). This makes the Protmex a powerhouse for heavy-duty tasks like removing stubborn nuts and bolts, outperforming the Milwaukee in sheer torque.
Battery and Runtime
Battery performance is crucial for cordless tools, and both models come with different battery solutions. The Milwaukee M18 FUEL is sold as a bare tool, meaning it does not include a battery or charger, which can be a drawback for users who do not already own Milwaukee batteries. In contrast, the Protmex includes two 4.0Ah batteries, which enhance its usability right out of the box. This setup not only allows for extended usage but also ensures that the tool is ready for demanding jobs immediately, making it a more convenient option for many users.

Its compact size and powerful motor make it suitable for a range of fastening tasks. However, the Protmex shines in versatility, being able to handle a variety of applications from automotive work to construction, thanks to its high torque output and dual control functions. This makes the Protmex a more versatile option for users who need a tool that can tackle various heavy-duty jobs.
Price and Value
The Milwaukee M18 FUEL is priced at $164.70, while the Protmex is available for $109.97, making it about 33% cheaper. Given that the Protmex also includes batteries, it presents a more compelling value proposition for users looking for a complete solution without additional purchases. While the Milwaukee may justify its price through its compact design and advanced features, the Protmex offers excellent performance for a lower cost, catering to budget-conscious consumers.
Which should you buy?
In conclusion, choosing between the Milwaukee M18 FUEL and the Protmex 1107Ft-lbs depends on your specific needs.
