  • Review Summary

    We are taking a look at two worthy miter saws that will face off in this article: the Bosch GCM12SD and the DeWalt DWS780.

    The DeWalt has the classic sliding action that most veteran woodworkers have come to expect. It has an XPS crosscut positioning system that provides an adjustment-free cut line indication. If you like things the way they’ve always been, you might lean more towards the DeWalt.

    The Bosch GCM12SD features a more modern design that fits in a smaller space. The double bevel allows for more versatile angle cutting than is possible with the DeWalt, and it’s better protected from dust during your reputation for durability and a long lifespan. We recommend the Bosch to those with a cramped wood shop, who aren’t thrown off by modern variations of tools.

    Overview of Bosch GCM12SD

    The Bosch GCM12SD features an axial glide system, which allows for wider cross cuts and improved alignment.  It also allows you to stay in a smaller space than a traditional miter saw would require.  The increased capacity allows you to cut 14 inches on the horizontal plane, and 6.5 on the vertical. Beveled detents allow for quick and accurate adjustments, and most controls are positioned up front where they are easy to reach.  The 15-amp motor delivers plenty of torque and allows the saw to reach up to 3,800 revolutions per minute (RPM).  It includes two quick-release fences for keeping your projects in line while you cut.

    The Bosch is a very smooth operating machine, and the only problem we had while reviewing it was that the on-off button is difficult to use while running the machine due to its poor positioning.  The fence is also a bit larger and clunky if you’re only working on small pieces, and there are no handles or grip spots to lift this heavy machine from the floor.

    • Axial glide system
    • 14-inch horizontal cutting capacity
    • Bevel detents
    • Upfront controls
    • 15-amp motor
    • 3,800 RPM
    • Two quick-release fences
    • The on-off button is difficult to use
    • The fence is large for cutting smaller pieces
    • Hard to lift

    Overview of DeWalt DWS780

    The DeWalt DWS780 features a precise miter system that helps improve the accuracy of your cuts. The 15-amp motor allows the saw to reach up to 3,800 RPM, which is more than enough to slice through even dense hardwoods. The integrated XPS crosscut positioning system uses a bright LED to cast a shadow on the work surface that tells the user where the blade will contact the wood. An adjustable miter plate has 10 detent stops for making fast and accurate angle adjustments. An efficient dust collection system helps remove harmful contaminants before they enter your lungs or the machinery housing. An integrated handle helps make the unit more portable.


    The downside to the DeWalt is that it’s difficult to assemble, and many of the bolt holes don’t line up and require coaxing to get them into place. It also tends to bottom out if you don’t use the depth stop, and it’s difficult to connect the dust port.

    • Precise miter system
    • Handle design for added portability
    • Integrated XPS crosscut positioning system
    • 15-amp motor
    • 3,800 RPM
    • Adjustable miter plate with 10 stops
    • An efficient dust collection system
    • Difficult to assemble
    • Bottoms out if you don’t use the depth stop
    • Hard to connect the dust port

    What Are the Differences Between Them?


    Edge: Tie

    Both miter saws use the same size engine to drive the same size blade at the same speed.  With such close specifications, it’s no wonder people compare these two saws so often.


    Edge: Tie

    At the time of writing, both models are the same price on Amazon, with the Bosch able to ship a few days earlier. But that could be due to our location, so we wouldn’t want to call it an edge.

    Edge: Bosch

    We must give the Bosch a slight edge in durability because the DeWalt tends to bottom out if you don’t use the depth stop, which could send plastic flying out from under the table.  It also was more difficult to assemble, and the tolerances didn’t seem as strict, which may result in a less durable machine.


    Edge: Bosch

    Again, we must award Bosch this category because their design allows the saw to fit in a smaller area of the workshop, which can be critical if you are low on space. It can also cut a wider range of angles, making it the clear winner in the design category.

    Both the Bosch and DeWalt miter saws are fantastic tools that will improve any workshop, and you would be hard-pressed to find a third equal. The difference between them is slight, but we would recommend the Bosch for most people because it has a smaller footprint in the workshop, and can do everything the DeWalt can with a little more versatility. If you are a seasoned veteran, you probably want the tool you expect—and in that case, the DeWalt is a perfect choice.

    We hope you have enjoyed reading our review and agree with our conclusions.  If we have helped you choose a new tool for your workshop, please share this shootout between the Bosch GCM12SD and the DeWalt DWS780 on Facebook and Twitter.
