Both miter saws are sliding compound and consist of a 12-inch diameter blade. The motor requires 15 amperes of current to operate, allowing the blade to rotate at 3800 revolutions per minute (RPM).

The dual bevel feature allows the cut to make in either direction (left or right) at a reasonable angle, explaining later very briefly.

Both of them come with a dust bag of satisfactory storing capacity to reduce the amount of pollution.

They require no batteries to operate; the connections are fully hard-wired. The back fence plan in these two-drop saws empowers cutting 2×16 measurements at 90 degrees and 2×12 at 45 degrees.

Dewalt is a very well-known company for its sturdy products. The same goes for these two models, which are made from high grading materials, thus giving them durability and strength.

What is the Difference Between Dws779 and Dws780?

Both models are high class in their way. As our article topic is Dws779 vs Dws780, some minor differences will make one of them a top-notch machine. Some of the factors that influence their performances are as follows:

  • Cutting guideline
  • Price
  • Weight
  • Detent plate

Cutting Guidance System

When it comes to the cutting mechanism, dewaltxps light system is the new trendy technology in the market. Model 780 consists of this which makes the cut more precise and accurate.

On the other hand, 779 has the option for the LED light system which you will have to buy separately. It is also accurate but not compared to the XPS.


The price of a single 779 model is 384.00 USD whereas 780 is worth 599.00 USD. You can see for yourself that there is a difference of 215.00 USD.

This lead to the comment that Dewalt miter saw 780 saw is expensive. This has to be the case because of their additional features.

If you have a thin budget or your use is not that much of a professional, then my suggestion will be to go for the 779 models.


When it comes to weight, Dewalt miter saw 780 has a great advantage, it weighs only 56 pounds. On the other hand, its counterpart weighs almost 70 pounds.

This is another feature of model 780 that it is portable. Though 56 pounds will take much elbow work, but still better than 70 pounds.

Detent Plate

This feature makes one of the discussed models in our article more unique than the other. 780 consists of stainless steel detent plate with a cam lock. It also gives you ease while making a vertical cut because of its rail lock.

On the other hand, 779 has a clamping mechanism which gives good precision and accuracy but is not compared to the detent plate.

My Verdict

To be honest! Choosing between these Dewalt models would be hard. Both of them contain such amazing features. In the case of professional use, the 780 model is a much better choice.

My brother and I have been doing a lot of your household work for quite a time now. We just brought the new version Dewalt miter saw and we are using it without any type of disturbance.

So, coming back to my opinion, if you are looking forward to marking your carpentry skill as a professional, Dewalt sliding compound dws 780 miter saw will be a perfect companion for you.
