The Essential Similarities in Features Between the Two Models

Just at the glance of the above table, it is apparent that both the models have various similarities in features. In this session, we will discuss these common features for both the models in more detail.


One of the essential components that determine the overall performance of your miter saw is the motor. The motor in both models comes with the same power and speed. It means that you will get the same advantages and performance of both the miter saws.

Both DWS779 and DWS780 feature an inbuilt power of 15 AMP motor that is capable of delivering a top speed up to 3,800 RPM. Hence, these miter saws deliver substantial power and speed, which can cut through various kinds of wood.

If you are only concern about motor power to accomplish the cutting jobs, then buy the DeWALT DWS779 Miter Saw. It withstands the test of time, well worth the money.


Most of the miter saws come with stainless steel blades. No doubt, it does the job pretty well. Nonetheless, an essential attribute that allows both the DWS779 and DWS780 to stand out is the Carbide Blade.

It is worth noting that carbide blades can withstand high temperatures and are resistant to abrasion. Besides, they do not need regular maintenance.

However, there is a slight difference when it comes to the quality of the blades. If you observed carefully, the DWS779 comes with a 32T blade, and the 60T blade goes to DWS780.

The higher the number of teeth, the finer is the cut. The DWS780 does have this advantage.

However, you can opt to bundle the 80T or 96T blade when you buy on Amazon regardless of which model you purchase. The DWS780 also includes the bundle for the miter saw stand if you wish to.

Cutting Capacity

It is not surprising to find some retailers labeling different cutting capacity between these two miter saws.

However, the truth is that both models have the same cutting capacity. They are capable of making cuts up to 6-¾ inches in depth.

Both these miter saws include a dedicated back fence. These saws are capable of making crosscuts up to 2×16 inches at 90-degree, and bevel cuts up to 2×12 inches at 45-degree.

Dust Collection

Another common feature for both the models relates to the dust extraction system. This feature will collect 75 percent of the generated dust, thereby keeping your workplace clean.

Nevertheless, the included bag for collecting the dust is relatively small. Hence, you will have to empty it frequently.


Since both models are identical, you may not notice much difference in weight. At 56 pounds, it is not the lightest miter saw on the market but still considered a portable unit for most of us.

It is hard to find a sturdy 12″ dual-bevel sliding compound miter saw that is not only lightweight but provides high accuracy and superb cutting performance. To be honest, we’re satisfied with its power-to-weight ratio.


The manufacturers have provided three years of limited warranty for both the models. With proper maintenance, these miter saws can last more than three years.

There are many DeWALT tools that last more than 10 years and are still working like a champ.

Main Differences Between DWS779 and DWS780

As mentioned, the DWS780 is an upgraded version of the DWS779. As such, there are some essential differences between the DWS779 and DWS780. Continue reading to know more about their differences:

LED Light

One of the main differences between the DWS779 and DWS780 is the cutting guide system.


The DWS779 does not include a laser guide for cutting, while DWS780 comes fully equipped with integrated XPS (crosscut positioning system) work light at the side of the blade.

The disadvantage of the laser guide is that the position usually gets knocked off when you are making cuts. It is also not suitable when working in a bright outdoor environment.

However, you do have to worry about these complications when using the DWS780. The XPS LED light maintains a proper position and effectively cast a shadow on the surface of the material.

This helpful upgrade helps you make more accurate cuts.


When it comes to the price, the DWS780 is more expensive than the DWS779. The difference in price relates to the fact that the newer model comes with a more advanced and unique LED lighting system.

If you want more precise cuts with the help of XPS LED light, then DWS780 will be an ideal option for you. However, you can opt for the DWS779 if you do not want the added lighting feature.

On the other hand, you can pick the DWS779 and install the advanced lighting system yourself. This way, you can save some money and still enjoy the advantage of XPS technology.

As such, it comes down to personal preference. Whatever is the case, both models provide effective performance considering the money.
