    Overview of DeWalt DWS779

    DEWALT Sliding Compound Miter Saw

    The DeWalt DWS779 is a top-notch machine. It has a super-efficient dust collection system that can capture over 75% of the dust created. It has a back fence designed that cuts up to 2×14 dimensional lumber at 90° and slightly smaller lumber at 45°. It can also be equipped with a LED light or laser cutting guide, though these are sold separately.

    It is a 12-inch double bevel sliding miter saw, which should be big enough for most projects. This is absolutely a bigger-than-average miter saw. However, that also makes it more expensive. Because of this, the average homeowner may not need such a large, expensive machine.

    It is easily adjustable, with a cam lock miter handle. It is also powerful at 15 amps and 3,800 RPM motor. It is mighty and plenty for both homeowners and professionals. Furthermore, this is also covered by a DeWalt warranty, which tends to be very reliable! Their customer service is quite good, so you can bet that you’ll be able to take advantage of that warranty if needed.

    Overall, this saw is dependable and well-built. It also isn’t expensive, though it does cost more than other models on the market. It is considered a mid-range model.

    • Well-built
    • Powerful
    • 16” straight cut capacity
    • 3-year warranty

    Overview of DeWalt DWS780

    DEWALT DWS780 12-Inch Double Bevel Sliding Compound Miter Saw

    The DeWalt DWS780 is very similar to the other one mentioned in this article. However, it is a bit more expensive (hence why it is the 780 and not the 779). It does come with a few extra features, which is one reason it is a bit more expensive.

    It has a handle design for portability and an improved precision system. Because it is a DeWalt, you can bet that it is built to last and extremely durable. We expect that this machine will serve you well for years to come. It has a stainless-steel miter detent plate with ten different stopping points, improving your accuracy and efficiency.

    Like many other DeWalt miter saws, this one has an efficient dust collection system that is made to capture over 75% of the dust created. It also has an increased vertical cutting capacity thanks to the gearbox and belt drive design. The back fence is designed to accommodate 2×14 lumber at a 90° angle, while it can cut slightly bigger lumber at a 45° angle.

    Pros
    • Handle for portability
    • Durable
    • Stainless-steel miter detent plate
    • Effective dust collection system
    • Increased vertical cutting capacity
    Cons
    • Expensive

    What Are the Differences Between Them?

    Price

    Edge: DeWalt DWS779

    The DeWalt DWS779 is cheaper by a few hundred dollars. If you’re on a budget or looking to save a bit of money, this can be a significant amount. That is a lot of money for most people and is something you should seriously consider before making your purchase design.

    Cutting System

    Edge: DeWalt DWS780

    The DeWalt DWS780’s cutting system is top-notch. It is the next innovation in cutting systems, which allows it to be more accurate than most of the competition. It uses a bright LED light, which casts a shadow as the blade is being used. This shadow provides a clear line, upping your accuracy.

    The DeWalt DWS779 uses a traditional laser-guided system. This isn’t bad, but it isn’t entirely as accurate as the other. It is reliable and still may work for some users, however.

    Miter Detent Plate

    Edge: None

    This is another significant difference between the two machines. The DeWalt DWS780 has a stainless-steel detent plate with a cam lock. It also has a rail lock, which allows you to cut vertically with more success. It also has a cam lock miter button to make angle adjusting easy.

    On the other hand, the DeWalt DWS779 has a double horizontal rail with an excellent clamping system. It works rather well and features a linear ball bearing, which makes cutting more accurate.

    Both of these systems are very different, but one is not necessarily better than the other. They are both excellent in their way and allow users to make accurate cuts. Which one you prefer is mostly a matter of your preferences, so we did not call one product the winner of this feature.

    Weight

    Edge: DeWalt DWS780

    The DeWalt DWS780 weighs less at only 56 pounds. It also has a handle for portability, though we wouldn’t call 56 pounds very portable. Still, it beats out its counterpart, which weighs more than 70 pounds.

    What the Users Say

    On top of the research we did, we also took the time to look at various user ratings and reviews. We checked online reviews, as well as outlets like forums.

    Generally, the DeWalt DWS780 is a high-quality option. However, it is also decently more expensive. Many users did not find the extra cost worth it. The DeWalt DWS779 is perfect for most users and is much cheaper. Users reported that it was a better value in most cases.

    However, the DeWalt DWS780 was the right decision for some users. Some particular users liked the portability of it, which the DeWalt DWS779 doesn’t have. Others had the extra money to spend and enjoyed the premium cutting system.

    Conclusion

    If you’re speaking only in terms of features, the DeWalt DWS780 wins. It is portable and has an innovative cutting system. However, when you take price and value into consideration, the DeWalt DWS779 may work best. It is accurate and able to perform most basic cuts, making it the prime option for homeowners.

    In the end, the one you choose depends on your budget and whether or not you want the extra features bad enough to pay the extra money. The DeWalt DWS779 is a budget option of the DeWalt DWS780.
