It can be challenging to match the features of different models to your individual needs and keep an eye on your price range at the same time. You might also be wondering if a miter saw is really the best tool for the work you have in mind, and you want to know that a product isn’t going to turn out to be lemon after you take it out of the box. We’ve put together this review with an eye on these things with both a first-time and a seasoned buyer in mind. We’ve put the tools we review to the test in a variety of situations that are typical for DIY and professional users to make sure they perform as well in the workshop as they do on paper. To get a sense of how durable the tools are, we use them for a couple months before we write our reviews to catch any quick breakdowns that can happen with shoddy workmanship. At the end of the process, we put the tools in context with similar models that might be better suited for the same applications compared to the tool we’re reviewing.

The Design

DEWALT DWS779DEWALT designed the DWS779 to be flexible and easy to set up. This comes through with the tall back fences and CUTLINE Blade Positioning System. It also has been outfitted with a powerful motor that adds metal-cutting to this saw’s repertoire.

With that said, we have to point out that most of these features are fairly standard among miter saws in its class. The real selling point of this saw’s design is its ease of use and quick setup times. If you need to cut many short runs in a day, the DWS779 is a good option to consider.

Precision and Performance

The DWS779 doesn’t skimp on precision or performance, keeping up with the pack and satisfying the expectations of most users. It’s blade positioning system lines up cuts precisely and is clearly visible as you cut.

It’s also designed to accept lumber up to 2 x 16 inches when making 90-degree cuts and 2 x 12 inches when making 60-degree cuts. The DWS779’s miter angle tilts well over 45 degrees in either direction, allowing you plenty of flexibility to set up cuts at awkward angles.

Pro Tip

One bad habit many beginners have is dropping the blade too fast for a cut instead of giving the motor time to get up to speed and lowering it slowly.

Safety Features

The DWS779 includes industry-standard safety features like a transparent blade guard that retracts when you lower the saw to make a cut and moves back into place when you lift it. This ensures that the blade only comes into contact with what is on the table when the saw is running.

It also has a trigger switch that can be locked out with a padlock when you need to perform maintenance. There is also an automatic electric brake that brings the blade to a stop within five seconds of releasing the trigger switch. All of this makes the DWS779 a safe tool to work with as long as you observe best practices.

DeWalt DWS779 vs DeWalt DWS780

Top DEWALT DWS779 Review - Powerful Saw For the Woodworking Collection (2019)
If you’re comparing DEWALT’s DWS779 and DWS780, you might be hard-pressed to find the difference between these two models without a close inspection.

That’s because the DWS780 is an incremental upgrade of the DWS779 that adds a new, more accurate blade positioning system that uses an LED light instead of a traditional indicator. It’s an improvement, but the remaining features of these two miter saws are virtually identical.

  • 15-amp motor has plenty of power
  • Adjustable, 10-stop detent plate
  • Effective blade positioning system
  • Comes with a 3-year warranty

  • This is not a portable saw
  • Inadequate dust collection system


Things we liked about it

The stainless-steel detent plate really makes setting up jobs at common angles much faster. You can adjust up to 10 positive stops to the positions you find yourself using often, so you won’t spend time dialing them in over and over again. The tall back fence is also much appreciated if you need to cut large lumber boards. The table can fit oversized boards as well, so you can cut down raw lumber stock quickly with this miter saw. The safety shield works smoothly to keep you safe and doesn’t get in the way of your work.

Things we didn’t like

This saw weighs in at 67 pounds, which makes it decidedly not portable. You can move it around the shop with the help of a lift, but you’ll probably want to place it in a good place for your workflow and leave it there. It’ll function best as a piece of fixed equipment that moves only occasionally when you rearrange your work area. The dust collection system could be better. DEWALT says that it catches 75% of the dust the saw creates, but the remaining 25% certainly can cause a mess to clean up at the end of the day.

General User Experience

DEWALT DWS779The vast majority of customer reviews have been glowing for this DEWALT model miter saw, which is a testament to its practical and effective performance. The DWS779 is officially obsolete, being replaced with the DWS780, but the DWS779 is still sold. Many customers are quick to recommend getting this cheaper saw that’s basically the same saw at a discount.

The DWS779 impresses with its powerful saw motor, which cuts through wood without any serious vibration problems that can reduce accuracy. It’s even quieter than many other miter saws. The blade positioning system works great as well, making the cutting experience a good one.

A downside to this miter saw is the inadequate dust collection system. While it does catch most of the dust, enough escapes that you’ll find yourself blowing out the motor from time to time. Another is its heavy weight for this size miter saw. It’ll sit in one place most of the time if you don’t have a rolling stand to mount it on.

What is a compound miter saw?

A compound miter saw can adjust the angle of a cut on two axes at the same time, called the bevel angle and the miter angle. The bevel angle is the blade’s tilt vertically from the saw table while the miter angle is the horizontal angle, or cross cut, measured from a line perpendicular to the edge of the piece being cut.

What is a sliding miter saw?

A sliding miter saw has a sliding feature also found with radial arm saws that makes it possible for the blade to move backwards and forwards. this gives the saw a longer cut length overall.

Can a miter saw be used to cut metal?

While miter saws are typically used for woodworking, you can buy special blades for many miter saws with the hardness and tooth-pattern needed to cut through metal. Be aware that cutting metal will cause more wear and tear on a miter saw that cutting wood. It’s not the ideal tool for the job, but certainly can be used to make bevel cuts in metal pipe or conduit on occasion.

For this DEWALT DWS779 review, our final verdict is that it’s a good choice for anyone who needs a compound sliding miter saw that can handle the stock you’d expect, can cut metal if you need it to, and has a good blade positioning system to ensure the accuracy of your cuts.

Does it have a bunch of other bells and whistles that boost the price tag on other miter saws?

No, but that’s fine if you just want a practical, entry-level saw that gets the jobs done. We were especially impressed with the efficiency of setting up this miter saw for different jobs, especially the detent plate that lets you set up stops for common cut angles.
