DWS779 vs DWS780 Compared – Main Features

DWS779 vs DWS780

The Engines

Everyone considers that the most important element of a miter saw is its engine. This part offers the tool’s performance. Therefore, you need to keep in mind a saw’s power and size to see if the machine is the right one for your projects. For instance, if your purpose is to make cuts in light surfaces, you will have to search for a not-so-powerful miter saw.

Both the DeWalt saws I am reviewing today come with a motor power of 15 amps. They are built-in circular saws created in a durable manner, and their engines deliver significant power. Moreover, the engines are both placed directly on the saws’ shaft, and they help the blades spin while reaching a speed of up to 3800 RPM. In other words, you will create quick and clean cuts on any kind of material you’re working with.

For what’s worth, both engines allow you to cut the material in one single movement. So, what I mean is that DWS779, as well as DWS780, is powerful enough and reliable.

The Blades

Both DeWalt tools feature stainless steel miter plates. These blades measure 12 inches and weigh almost 60 lbs. While these two products were pretty similar when it comes to engines, in terms of blades, there’s an essential difference.

The initially-launched model features one steel blade while the second tool comes with two blades: a steel one and a carbide one. Carbide is a dense material that’s known and appreciated for its durability and versatility.

Also, carbide blades lead to cleaner and smoother cuts while also leaving sharp edges. Finally, being so sturdy, you won’t need to do a lot of maintenance because this type of blade remains sharp for a long time, which eventually helps you benefit from a long-lasting cutting tool.

The Guide System

The major difference that sets these two miter saws apart is given by their guide system. Although both machines have reliable laser guide mechanisms, the DWS779 model features a more traditional one.

At the same time, the DWS780 saw enables you to enjoy the benefits of an XPS system that includes a bright LED light. This light shines all the way across the blade’s length. This way, you will increase the precision of your cuts because the light and the created shadow follow the blade’s movement.

The XPS system is an extremely amazing feature due to the fact that it allows you to maintain very precise alignment. With DWS779, this is not possible at the same level because the tool can move one way or the other without keeping the proper alignment.

On the other hand, if your work environment is brightly illuminated, the saw’s LED feature can be affected because the shadows become less visible. Nevertheless, in most domestic settings, having this particular characteristic comes in handy and works perfectly.

Additional Features

There are two useful bonus features that both tools provide:

  • The first one is an exclusive back fence which gives you the possibility to adjust your desired cutting angle to either 90 or 45 degrees;
  • The second one is a dust collection system that is solid and keeps your working space clean while also keeping your nose, eyes, and lungs healthier and dust-free.

The fence is definitely a perk because not many cutting tools have this feature. The dust collection is one of the most important and most useful characteristics of all because cutting materials at high speeds will produce plenty of volatile residues that can negatively impact your vision while also getting into your respiratory system. Nevertheless, the manufacturer still suggests you to always wear protective gear while working with these miter saws.

Some people choose the latest version (the DeWalt DWS780) because they want to work with something more sophisticated, while many other individuals are satisfied with the more traditional DWS779 saw. Believe it or not, the XPS system represents a great addition, especially for inexperienced users, because it improves the alignment process quite a lot.
