Updated August 2026 — full head-to-head comparison.
Overview of the Milwaukee M18 FUEL and ReliaRoads Impact Wrenches
The Milwaukee M18 FUEL offers compactness and advanced features, while the ReliaRoads impact wrench shines with its higher torque and lower price. The Milwaukee is priced at $164.70, while the ReliaRoads is about 58% cheaper at $69.97. This stark price difference reflects their distinct market positions and functionalities.
Design and Build Quality
Both impact wrenches are designed for specific tasks, but their build quality and design focus differ significantly. The Milwaukee M18 FUEL is noted for its compact size, measuring just 4.8 inches in length, which allows for easy maneuvering in tight spaces. This design is particularly beneficial for those working in confined areas. On the other hand, the ReliaRoads model, while bulkier, features a user-friendly design with an ergonomic anti-slip grip, making it comfortable for extended use.
Performance and Power
When it comes to performance, the ReliaRoads impact wrench significantly surpasses the Milwaukee in raw power, boasting an impressive 900 ft-lbs of torque compared to Milwaukee’s 250 ft-lbs. This difference highlights the ReliaRoads tool's capability for heavy-duty tasks like automotive repairs and machinery maintenance. However, the Milwaukee's performance is enhanced by its POWERSTATE Brushless motor, which is designed to tackle stubborn fasteners effectively, albeit at a lower torque level.
Battery Compatibility and Usage
Battery compatibility is a critical factor for many users. The Milwaukee M18 FUEL is compatible with M18 REDLITHIUM batteries, which are known for delivering more work per charge. However, these batteries are sold separately, which can add to the overall cost. In contrast, the ReliaRoads impact wrench is designed to work with DeWalt 20V MAX batteries, which may appeal to users who already own DeWalt tools. Both products are sold as bare tools, meaning that users will need to purchase batteries separately, but the choice of battery system can significantly affect usability.
Special Features
The Milwaukee M18 FUEL comes equipped with several advanced features, such as tri-LED lighting that enhances visibility in dark workspaces and a 4-Mode DRIVE CONTROL for greater precision. The AUTO SHUT-OFF feature prevents overtightening, which is advantageous for delicate fasteners. Meanwhile, the ReliaRoads model offers a 3-speed mode (450-650-900 ft-lbs) that allows users to switch between torque levels, providing enhanced control depending on the task at hand. This versatility is particularly useful for jobs requiring different levels of torque.
Price and Value
In terms of price, the Milwaukee M18 FUEL is positioned at $164.70, reflecting its advanced features and brand reputation. The ReliaRoads, however, is priced at $69.97, making it a budget-friendly option for those who require high torque without breaking the bank. This price difference of approximately $94.73 may be a deciding factor for users looking for value without sacrificing performance.
Sales Rank and Popularity
Popularity metrics can provide insight into consumer preferences. The Milwaukee M18 FUEL holds a sales rank of 13,255, indicating it is a well-regarded choice among users. In comparison, the ReliaRoads impact wrench has a sales rank of 15,813, which, while still respectable, suggests it may not have the same level of market penetration or brand recognition as Milwaukee. This could influence a buyer's decision, particularly if they value brand reputation and proven performance.
Which should you buy?
Choosing between the Milwaukee M18 FUEL and the ReliaRoads impact wrench ultimately depends on your specific needs and budget. If you prioritize compactness, advanced features, and are willing to invest in a higher-priced tool, the Milwaukee M18 FUEL is an excellent choice. However, if you seek a more affordable option with superior torque for demanding tasks, the ReliaRoads impact wrench offers significant value at a lower price point. Consider your existing battery compatibility and the type of work you’ll be doing to make the best decision for your needs.
