Dewalt Dws779 vs. DWS780 – What Are the Main Differences?

There are so many similarities between the DWS780 and DWS779. Dewalt wanted two saws that looked similar but had different features. Both Dewalt miter saws are ideal for use, but the DWS780 is like an upgrade of the two.

Therefore, some of its advanced features are better. Let’s take a look at different factors to see the differences between them:


Generally, you can pay less for the DWS779, so there’s an advantage there. It’s more affordable and costs about $100 less than the DWS780.

The difference in price is because the DWS780 is more advanced. However, just because the DWS779 is cheaper doesn’t mean it doesn’t have good value for money. Yes, it’s more affordable, and you can outperform the DWS780 at times.

Therefore, you can spend less, get something cheaper, and still have a durable motor and a model that does everything you need.


One significant difference between each model is that the DWS780 has a bright LED light with the blade and the DWS779 utilizes an XPS light. It also offers a cut-line blade position system that can easily be adjusted so that you enjoy the free cutting line indicator.

Many users prefer an LED light compared to lasers. That’s because the LED light is properly positioned and the laser guide system could get knocked out of position when cutting. Plus, the LED light projects a shadow line for the blade’s teeth, and the laser guide system does not.

This means that your cuts could be a bit off with the laser systems. The laser-cut line might get lost in the LED light.

Another big issue with laser beams is that they function better at nighttime. With the dust and noise flying around, it can overwhelm the senses and could affect accuracy.


The DWS779 is much heavier at 67 pounds, but the DWS780 is lighter and weighs 56 pounds. Therefore, it’s easy to carry around and is more portable than the other model.

Miter Detent Plate?

The miter detent plate settings are also a huge difference between each model. The DWS780 uses a stainless steel version with a cam lock, but the DWS779 uses a lever camp with 10 positive stops.

With that, the DWS779 offers a double horizontal rail and an innovative clamping device. You have more accuracy with cutting because of that linear ball bearing. There are no linear ball bearings with the DWS780, and it uses a rail lock to improve its vertical cutting capacity. You also have a better angle adjustment because of the cam-lock miter button.

However, the difference in miter detent plate is a matter of preference. You get an excellent clamping system in either case, so there is no hassle when using it.

Frequently Asked Questions

Can You Use the XPS System with Your Dewalt Sliding Miter?

Yes, you can use an XPS system for either model. You can add LED lights with your saw if they aren’t compatible with laser light. However, comparing them both, the XPS system fits well with the DWS779 models because there’s a wider space below its grip.

Which One Should You Use to Cut Fiberglass Rods?

Generally, the miter is there to cut hardwood and metal. However, many people find that the performance of each saw was similar when cutting fiberglass.

Which Stands Are Recommended?

There are supposed to stand with each product, but you must pay for them separately. Therefore, you should buy the one that gives you more convenience. Rolling stands are often best here.

DWS780 vs. DWS779 Conclusion – The Top Pick

The top pick here is the DWS779, and it’s a consideration for beginners everywhere. It has practically everything you need for your project, including a great crosscutting capacity and the ability to make bevel cuts. That way, you don’t have to flip the piece over to cut the other side.

The Sliding Compound Miter Saw could be the best miter saw on the market for your woodworking needs. Just follow the directions, and you’re set, creating just about anything you want.

When purchasing a miter saw, an LED light isn’t a necessity, and many projects don’t require it. While the 780 version uses it, it’s the only upgrade to the whole thing. In fact, the LED lighting makes it more expensive.

You can use the DWS779 from Dewalt straight out of the box. What are you waiting for?
