Dewalt is a trusted name and one of the biggest names in the tool market these days. For hundreds of years now, this brand has managed to remain on top making increased sales of its products. If you are planning to purchase a Dewalt tool, particularly miter saws, you might get into confusion as there are three compound sliding miter saws to choose from-the DW709, DWS 779, and DWS 780. Now you might be thinking which one should you buy?

Leave your worries behind as this review will talk about these saws, compare, and after that, you will inevitably end up with the right option that perfectly suits your needs. As for the basic, all of these miter saws DW709, DWS 779, and DWS 780 have the same blade diameter, which measures about 12 inches providing 3,800 rpm. All of these saws have stainless steel miter dent plates.

There is also a 3-year warranty period applying to all models. However, there are also substantial differences. It is for this reason that this review was written. To help you decide which among the three miter saws can suit your exact requirements.

General Descriptions of the Products

When buying any product, including a miter saw, it pays to be familiar with the descriptions and features of the product, so you are aware of what you are getting.

Made for hassle-free and easy use, the capacity of the saw is 0 -60 degree left, 0- 50 degree right, bevel 0 -48 degrees right and left, cross cuts 2×14 on and 90 degree and miters 2×10 on 45 degrees.

The product is also noted for its 13 positive stops enhancing productivity and ensuring unmatched cutting accuracy.

Dewalt Dws779 vs. Dws780 vs.  Dws709 – Know the Differences

These miter saws differ from each other based on the following:

Cutting Capacity and Accuracy

A miter saw would be useless if it cannot deliver unmatched accuracy on the cutting materials. Dewalt takes pride in all their miter saws as these perform in excellent ways in this category and can get rid of any accuracy issues.

However, the difference is that DWS709 miter saw only has 13 positive stops while Dewalt DWS 779 and DWS 780 have 10 positive locks along with cam lock. DWS 780 has an XPS system for ultimate accuracy.


Both the DWS709 and DWS 779 provide everything users need in quality miter saws, including power, accuracy, and precision. However, DWS 780 excels when it comes to precision and versatility. But this does not mean that DWS709 and DWS 779 lack anywhere.

Portability and Weight

DWS 779 is heavy in its 67-pound weight. However, DWS 709 features compact designs making this model lightweight, at 50 pounds. This is, therefore, light, considering it’s a sliding compound miter saw. The DWS 780 is the lightest in its 56-pound weight.

Dust Collection

All models feature dust collection capability. DWS 709, however, might require the use of an external vacuum for much better performance. This same applies to DWS779, which includes a dust bag. But if dust collection is a deciding factor for you, skip this model. DWS780 is the runaway winner under the category. This model excels in dust collection while the two models struggle in collecting dust.

Dewalt Dws779 vs. Dws780 vs.  Dws709 Pros and Cons

Just like any other tools, DWS 779, 709, and 780 miter saws also have their own sets of pros and cons. These are highlighted below:
