Differences Between DeWalt DWS780 vs Milwaukee 6955-20
Below is a summary of the specifications:
Motor Power and Cutting Performance
The DeWalt DWS780 operates with a 15-amp motor at 3,800 RPM, delivering reliable speed and power for framing lumber, hardwoods, and finish carpentry. Its fixed-speed design is simple but effective, offering a balance of speed and torque for various materials.
The Milwaukee 6955-20 also uses a 15-amp motor, but with a variable speed control ranging from 3,200 RPM downward. This allows users to tailor blade speed to the material, reducing tear-out in delicate trim or maintaining control on dense hardwoods. Its lower top RPM compared to DeWalt is offset by the benefit of adjustability, especially for specialty cuts.
Winner: Milwaukee 6955-20 – Variable speed control gives it greater versatility across different materials.
Cutting Capacity and Versatility
The DeWalt DWS780 offers a 13.75-inch crosscut width and a 6.75-inch vertical cutting capacity, making it well-suited for wide boards, baseboards, and crown molding. Its tall sliding fence supports up to 7.5-inch crown molding nested vertically, which is particularly valuable for trim carpenters.
The Milwaukee 6955-20 slightly outperforms in horizontal cuts with a 14-inch crosscut capacity, though its 6.5-inch vertical height is marginally smaller than DeWalt’s. It supports 6.75-inch crown molding, which is slightly less but still adequate for most trim projects.
Winner: Tie – DeWalt excels in vertical and crown molding capacity, while Milwaukee has a slight edge in crosscut width.
Miter and Bevel Adjustments
The DeWalt DWS780 provides a miter range of 50° left and 60° right with 10 positive stops on a stainless steel detent plate. The dual bevel capability of 48° left and right ensures quick adjustments for compound cuts, with a cam-lock miter handle for secure settings.
The Milwaukee 6955-20 matches the miter range of 50° left and 60° right and also offers a dual bevel of 48° left and right. What sets it apart is its digital miter angle readout, accurate to 0.1°, combined with a fine adjustment system. This makes dialing in precise angles significantly easier, particularly for cabinetry and custom trim installations.
Winner: Milwaukee 6955-20 – Digital miter angle readout and micro-adjust controls deliver unmatched precision.
Precision and Accuracy
The DeWalt DWS780 uses the XPS LED shadow line system, which casts a blade shadow on the workpiece. This method requires no calibration, always stays aligned with the blade, and works in both indoor and outdoor lighting. Its simplicity and reliability make it a favorite for contractors who need consistent accuracy with minimal fuss.
The Milwaukee 6955-20 features a digital miter angle display and fine adjustment mechanism, enabling precision that goes beyond most saws in its class. This technology allows cuts to be set with extreme accuracy, a feature highly valued by finish carpenters and professionals working with custom joinery.
Winner: Tie – DeWalt provides consistent, low-maintenance precision with the shadow line system, while Milwaukee offers superior fine-tuned accuracy through its digital system.
Build Quality and Portability
The DeWalt DWS780 is built for rugged jobsite conditions while remaining relatively lightweight at 56 lbs. Its durability is proven, and its lighter weight makes it easier to transport between sites.
The Milwaukee 6955-20 is heavier at 77 lbs, but this weight translates to exceptional stability during cutting. Its robust frame and design ensure minimal vibration, but portability suffers compared to DeWalt’s lighter build.
Winner: DeWalt DWS780 – Lighter and more portable, making it the practical choice for mobile contractors.
Dust Collection Efficiency
The DeWalt DWS780 achieves around 75% dust collection efficiency, which is sufficient for outdoor and jobsite use but leaves more fine particles behind in indoor environments.
The Milwaukee 6955-20 integrates a dual dust channel system, capturing debris from both sides of the blade. This improves dust management considerably, keeping the workspace cleaner and visibility clearer during cutting.
Winner: Milwaukee 6955-20 – Dual dust channel system offers superior collection and cleaner operation.
Ease of Use and Adjustability
The DeWalt DWS780 emphasizes ease of use, with intuitive controls, fast setup, and the XPS shadow line system that requires no adjustments. It is straightforward and efficient, ideal for professionals who prioritize speed.
The Milwaukee 6955-20 provides more advanced adjustability. Its digital angle controls, variable speed, and fine-tuned micro-adjust features give professionals greater flexibility, though the learning curve is slightly steeper compared to DeWalt’s simplicity.
Winner: Tie – DeWalt offers straightforward usability, while Milwaukee provides advanced adjustability for expert users.
