An LED light comes in handy when making cuts using your miter saw. It helps cast a shadow of the blade on the workpiece you are working on so you can have a guided cutting operation. Consequently, you will have more precision and accuracy during cuts.

While this feature is robust and helpful, users of the DWS779 miter saw model cannot benefit from it since the unit lacks the feature.

On the other hand, there is an LED light on the DWS780 model. This means it is more accurate. It also produces a higher level precision than the DW779 model.

  • The Ruggedness

The more rugged a miter saw model is, the better it can handle heavy-duty cutting operations. When you look at the two models of miter saws by DEWALT, you will find differences in ruggedness.

These models are all ideal for professionals. However, there is stainless steel in the design of the DW780 miter saw model. This makes it more rugged that the DWS779 model.

The difference in the prices of these two products narrow down mostly to the XPS system. Because these machines are almost the same, the laser guide system however brings such a huge distinction.

The XPS system comes in handy for users since it helps in maintaining alignment while cutting any material. This is because maintaining alignment when cutting is usually a very tricky process.

This feature that DWS780 has benefits most experienced and new users.


Both miter saws perform well when cutting wood. However, there are some subtle differences between them. You will not notice much of a difference in the cuts since both models produce fine cuts.
