Dong Cheng 20V MAX 7-1/4'' Brushless Cordless vs Milwaukee M18 FUEL 6 1/
Updated July 2026 — full head-to-head comparison.
Overview of the Dong Cheng 20V MAX and Milwaukee M18 FUEL
The Dong Cheng 20V MAX 7-1/4'' Brushless Cordless Circular Saw Kit is priced at $96.59, making it a significantly more budget-friendly option compared to the Milwaukee M18 FUEL 6-1/2 Inch Plunge Track Saw, which costs $365.00. This price difference of about 72% positions the Dong Cheng as a strong contender for those looking for a powerful tool without breaking the bank.
The Dong Cheng circular saw features a robust 850W brushless motor, delivering 5000 RPM, ideal for cutting through various materials such as hardwood and plywood. In contrast, the Milwaukee saw boasts a POWERSTATE brushless motor capable of reaching 6300 RPM, providing high performance for professional carpenters and remodelers. Both tools offer notable power, but the Milwaukee's higher RPM may appeal to those seeking a faster cutting experience.
Design and Usability
When it comes to design, the Dong Cheng saw is lightweight at 3.8kg, making it highly portable for on-site jobs. Its cordless feature, powered by a 20V 4.0Ah lithium-ion battery, provides freedom of movement without being tethered to a power source. The saw also includes an integrated dust port for better visibility during cutting, which is essential for detailed work.
On the other hand, the Milwaukee M18 FUEL is engineered for precision with a variable speed dial that allows users to set the RPM according to their specific application. This feature, along with a smooth plunging action for easy plunge cuts, makes it excellent for intricate tasks. However, the Milwaukee is a bare tool, meaning users need to purchase the battery and charger separately, adding to the overall cost.
Cutting Capabilities
The cutting capabilities of both saws cater to different needs. The Dong Cheng saw offers a maximum cutting depth of 65mm at 90 degrees and 45mm at 45 degrees, making it suitable for standard framing tasks with 2x4 lumber. Additionally, it comes with both 24T and 40T carbide blades, providing versatility for ripping and fine cuts.
In comparison, the Milwaukee saw is designed for professional use with features such as adjustable cam systems to ensure the perfect fit on track rails for straight cuts. Its riving knife also prevents materials from pinching the blade, reducing kickback and enhancing safety during operation. While the Dong Cheng caters more to DIY enthusiasts and general contractors, the Milwaukee is tailored for professionals needing precision and reliability in demanding environments.
Dust Management
Effective dust management is crucial for maintaining a clean workspace, and both tools have features addressing this concern. The Dong Cheng circular saw includes an integrated dust port that can connect to wet/dry vacuums or sawdust bags. This feature significantly reduces cleanup time, especially in confined spaces like drywall cutting or subfloor installations.
Conversely, the Milwaukee saw also offers a vacuum port and dust bag, ensuring high dust collection efficiency. Milwaukee claims over 90% dust collection efficiency, which is impressive for users who prioritize a clean work environment. The superior dust management of the Milwaukee may justify its higher price for some customers who work frequently with dusty materials.
Safety Features
Safety is paramount when using power tools, and both the Dong Cheng and Milwaukee saws incorporate safety features designed to protect users. The Dong Cheng saw features a trigger lock switch to prevent accidental startups, which is particularly important when working in elevated positions like ladders or rafters. Its anti-slip grip and balanced design also help reduce arm fatigue during extended use.
On the other hand, the Milwaukee saw is equipped with multiple safety features, including a riving knife that minimizes kickback and ensures users maintain control during cuts. This added safety may be particularly appealing to professional users who prioritize both performance and safety on the job site.
Battery Life and Performance
Battery life and performance are critical factors for cordless tools. The Dong Cheng saw utilizes a 20V 4.0Ah lithium-ion battery, providing ample power for various cutting tasks. The interchangeable battery is compatible with other tools in the Dong Cheng lineup, enhancing versatility for users who own multiple tools.
In contrast, the Milwaukee M18 FUEL is designed to work with the M18 REDLITHIUM HIGH OUTPUT XC6.0 battery, which delivers more cuts per charge than competitors. This battery system is engineered for durability and high performance, making it a reliable choice for professionals who require consistent power throughout the day. However, since the Milwaukee is sold as a bare tool, users must factor in the cost of the battery and charger when considering overall value.
Price Comparison and Value
The price difference between the Dong Cheng and Milwaukee saws is substantial. The Dong Cheng 20V MAX is priced at $96.59, while the Milwaukee M18 FUEL is sold for $365.00, making the Milwaukee approximately 72% more expensive. This price variance raises essential questions about the value each tool offers relative to its cost.
For casual users or DIY enthusiasts, the Dong Cheng saw provides an excellent balance of performance and affordability, making it a great choice for general tasks around the home or job site. However, for professionals who demand superior cutting performance, precision, and advanced features, the Milwaukee may justify its higher price.
Which should you buy?
Choosing between the Dong Cheng 20V MAX and the Milwaukee M18 FUEL ultimately depends on your specific needs and budget. If you are a DIY enthusiast or a contractor seeking a reliable, budget-friendly circular saw, the Dong Cheng offers impressive performance and features at a fraction of the cost of the Milwaukee. However, if you are a professional looking for a high-performance tool with advanced capabilities and superior dust management, the Milwaukee M18 FUEL stands out as the clear choice.
