DeWalt tends to make power tools that are almost identical except for just a few minor variations. Two such models are their DWS709 and DWS779 miter saws, and at first glance, it is hard to tell them apart.

Both tools make some fantastic cuts and are handy to have in the workshop. Hence, you will still have a high-performing miter saw, regardless of which you choose. However, here we compare them side by side to help you make a more informed choice.

Overall Findings



  • 4.5” max vertical & 9.5” horizontal cut capacity
  • Decent crosscut capacity of 2×14 at 90° & 2×10 at 45°
  • 13 positive stops on miter detent plate
  • Requires external light source to illuminate the workpiece
  • A little lighter at 51 lbs for max portability
  • Pricier but still quite reasonably priced
  • 6.75” max vertical & 9.65” horizontal cutting capacity
  • Larger crosscut capacity of 2×16 at 90° & 2×12 at 45°
  • 10 positive stops on miter detent plate
  • Onboard LED for illuminating the workpiece
  • Weighs a bit more at 56 lbs but still quite portable
  • Comes at a lower price tag

DWS709 vs. DWS779

1. Cutting Capacity: DWS779 offers a Relatively Higher Capacity

Cutting capacity is the main element that sets these two miter saws apart and should hence be the main factor to consider when picking between them. Here, the DWS779 has an edge for all cut types, from vertical and horizontal cuts to crosscuts.

With the DWS779, you get a maximum cutting thickness of 6.75 inches, and you can make a maximum horizontal cut of up to 9.65 inches. The DWS709 has a slightly smaller cutting capacity than this as it can cut materials up to 4.5 inches thick and make horizontal cuts of up to 9.5 inches.

For the cross cuts, the capacity of the DWS779 is 2x16 at 90-degrees and 2x12 at 45 degrees. The DWS709 allows you to cut 2x14 at 90 degrees and 2x10 at 45 degrees.

Despite the differences in the cutting capacity for these two miter saws, it is vital to note that both use the 12-inch blade. What’s more, these sliding compound miters saws will also run on 15-amp motors that deliver up to 3,800 RPM.

2. Miter Detent Plate: More Positive Stops for the DWS709

Both the DWS709 and DWS779 have a sturdy stainless steel miter detent plate. However, the difference between the two here is in the number of positive stops that you get.

The DWS709 offers 13 positive stops, which is a few stops more than the 10 you get with the DWS779. Hence, the former will give you more points to fix the angle of the blade to ensure maximum cutting accuracy.

While the few extra positive stops give the DWS709 an edge here, the DWS779 has the advantage of having a cam-lock. A cam-lock makes it easier to secure the workpiece in place and eliminates the need to twist a knob, something that many woodworkers and DIYers don’t like.

3. LED Light: The DWS779 has a Clear Edge Here

Depending on the bundle you buy, the DWS779 can come with an onboard LED light that will allow you to illuminate the workpiece when cutting for increased accuracy. Better yet, this miter saw has an optional XPS laser cutting guide for even more accurate cuts.

The LED light and laser guide are missing on the DWS709. But, while this might not seem like a significant difference between the two miter saws, they are still convenient features that can have a substantial impact in certain situations such as when making cuts in dark workshops.

4. Weight & Portability: Highly Portable Miter Saws

As a woodworker or DIYer, you may need to carry your miter saw for use at different job sites. The good news is that both DWS709 and DWS779 are quite portable power tools.

That said, the DWS709 is relatively lighter as it weighs 51 pounds, making it easier to carry around. The DWS779, on the other hand, weighs 56 pounds, and for some users, the 5 extra pounds will not make a significant difference.

5. Price: Both Still Offer Good Value for Money

Overall, these sliding compound miter saws will give you great value for money given their cutting capacities, features, and functionalities. However, the DWS779 is the cheaper of the two by at least $80, depending on where you are buying.


The choice between the DWS709 and DWS779 will often boil down to your preferences, how you intend to use it, and of course, your budget.

That said, if you are looking for something portable for smaller projects involving the use of large and thick materials, the DeWalt DWS709 is an ideal choice.

However, if you want to save some bucks and prefer a miter saw with a relatively higher cutting capacity to handle medium to large projects, go with the DeWalt DWS779.
