DeWalt 12 in. Double-Bevel Sliding Compound Miter Saw Review

4.7 out of 5

The DeWalt DWS780 12 in. Double-Bevel Sliding Compound Miter Saw is a tool that has quickly become a staple in my workshop. As a long-time user of various miter saws, I was eager to see how this model would perform, and I must say, it has largely lived up to its reputation.

Design and Build Quality

Straight out of the box, the DWS780 impresses with its robust build. Weighing in at 56 pounds, it's not the lightest saw on the market, but the weight contributes to its overall stability during operation. The saw is predominantly silver and yellow, a signature DeWalt color scheme that adds a professional touch to any workshop or jobsite.

One of the standout features is its compact and lightweight design, which makes it relatively easy to transport and store. The cam lock miter handle allows for quick and accurate angle settings, a feature that I found incredibly useful for various cutting tasks. The dual horizontal steel rails with clamping mechanism add to the saw's durability, ensuring that it can withstand heavy use over time.

Performance

The DWS780 boasts a powerful 1675W motor, which drives the 12-inch blade at a speed of 3800 RPM. This power is evident when making cuts, as the saw handles everything from soft pine to hardwoods with ease. The gearbox and belt-drive design increase the vertical cutting capacity, making it possible to cut larger pieces of lumber without any issues.

The saw's cutting capacity is another area where it excels. With a maximum cutting capacity of 2x14 inches at 90°/90° and 2x10 inches at 45°/45°, it can handle a wide range of cutting tasks. The tall sliding fences support larger crown and base moldings, which is particularly useful for trim work.

Accuracy and Adjustments

One of the most crucial aspects of any miter saw is its accuracy, and the DWS780 does not disappoint. The integrated blade positioning system provides accurate cut line visibility, ensuring that your cuts are precise. The oversized bevel scale allows for easy and precise angle adjustments, which is essential for detailed work.

However, I did encounter a minor issue with the sliding operation. While the saw cuts fine in non-sliding mode, the sliding operation sometimes results in a slight curve, which can be frustrating when precision is paramount. This is something to be aware of, especially if you plan to use the sliding feature frequently.

Dust Collection

The efficient dust collection system is a notable feature, but it does have room for improvement. While it does a decent job of collecting dust, it’s not perfect and some dust does escape. If you’re using the saw indoors or in a workshop, connecting it to a shop vac might be a better solution to keep your workspace clean.

Safety and Usability

Safety is always a concern with power tools, and the DWS780 includes several features to ensure user safety. The saw comes with a safety switch on the start button trigger, which is easy to use and provides peace of mind that the saw won’t accidentally start. However, there have been reports of issues with the rear guard assembly, so it’s essential to ensure that your saw is up-to-date with any recalls or safety notices from DeWalt.

LED Shadow Line

One feature that sets the DWS780 apart is the XPS LED shadow line system. This system casts a shadow of the blade onto the workpiece, providing a clear and precise cut line. While this feature is incredibly useful, it has been reported to fail prematurely in some units. In my experience, it worked flawlessly, but it’s something to keep in mind if you rely heavily on this feature.

Portability and Storage

Despite its weight, the DWS780 is relatively easy to transport, thanks to its compact design. However, its size can be a drawback in smaller workshops. The saw requires a fair amount of space, especially when using the sliding feature, so ensure you have adequate room before making a purchase.

Pros and Cons

Pros:
- Powerful motor and high RPM for smooth cuts
- Accurate and easy-to-use adjustments
- Tall sliding fences for larger moldings
- Efficient, though not perfect, dust collection system
- Integrated XPS LED shadow line for precise cuts

Cons:
- Sliding operation can result in slight curve cuts
- Dust collection could be more effective
- Issues with the LED shadow line failing prematurely
- Requires significant space for use and storage

Final Thoughts

The DeWalt DWS780 is a robust, powerful, and highly accurate miter saw that excels in most areas. It’s well-suited for both professional carpenters and serious DIY enthusiasts. The saw’s powerful motor, precise adjustments, and useful features like the XPS LED shadow line make it a valuable addition to any workshop.

However, it’s not without its flaws. The sliding operation’s potential for curve cuts and the less-than-perfect dust collection system are areas that could use improvement. Additionally, the issues with the LED shadow line system are worth noting, especially if you rely on it for precise cuts.

Overall, I would recommend the DeWalt DWS780. Its strengths far outweigh its weaknesses, and it offers a level of performance and reliability that is hard to beat in its class. Just be prepared to address some minor issues and ensure you have the space to accommodate this impressive tool.
