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.

Versatility

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
