DEWALT DWS709 Review


This is a very powerful miter saw model by DEWALT. It has a 15-Amp electric motor that spins at 3,800 RPM. Also, it’s a corded power tool. The result is an extended fast and powerful performance.

It can cut through various materials despite their enormous thickness. Despite packing such an impressive performance, this miter saw is compact and lightweight.

It weighs only 51 pounds. You can transport it with less effort. Also, it takes up less space while in storage or during transit.

Since safety is a major concern, it features a transparent blade guard. The blade guard lets you examine your cuts as it protects you from the blade. The handle is ergonomic for comfort and longer working hours. The handle features a power switch for controlling the blade.

Once you disengage the power switch, the blade ceases to spin after a few seconds. That gives you more control with only one hand! If you’re looking to make repeated but accurate miter cuts, then this tool is for you. That’s because this miter saw model has a miter dent plate with 13 positive stops.

The dent plate brings unmatched accuracy besides being durable. It miters 60 degrees to the right and 50 degrees to the left. Contractors who often make bevel cuts can also use this miter saw. The bevel scale is over-sized to give you more room for adjustability and accuracy.

Aside from accuracy, this miter saw model has an impressive cutting capacity. All thanks to the impressive back fence design. You can cut 2×14 dimensional lumber at 90 degrees. Also, you can cut 2×10 dimensional lumber at 45 degrees with this tool.

You can cut crown molding of up to 5.5 inches nested on the miter saw. And cut base molding of up to 4.5 inches vertically placed on the fences.

That’s possible because this model has tall sliding fences in place. If you opt for this tool, you get a dust bag, carbide blade, blade wrench, material clamp and user manual.

DEWALT DWS779 Review


Looking at power and fast performance, this miter saw model is in the same category as DEWALT DWS709. It has a powerful and fast 15-Amp electric motor that generates blade speeds of up to 3,800 RPM. Also, it’s a corded miter saw model.

It means it uses mains electricity as its power source via a cord. As such, it uses a very stable power source, and it can run for long. This makes it yet another ideal miter saw for heavy-duty material cutting operations.

Though it weighs a few pounds extra compared to the DWS709 model, it’s still a portable unit. Lifting the 56-pound miter saw isn’t much of a chore. It takes up less space while in storage with its 2 x 23 x 18.5-inch dimensions.

The handle has the same ergonomic design as the DWS709 model. It even features a power switch on the handle, just like the DWS709 model. That means more control of the miter saw with only a single hand!

The Difference Between Dewalt DWS709 And DWS779

DEWALT is a company that has gained a reputation for its high-performance power tools. Every tool in their product line has enough power for the designed project. And their miter saws are no exception.

So we’ve looked at two models. The question is: which model should you buy? To answer this question, let’s look at the following factors:

dws779 vs dws709
  • Weight and compactness

If you look at the two miter saw models, you’ll find weight and size differences. Weight plays a crucial role when it comes to the stability of a miter saw. The heavier a miter saw model is, the more stable it becomes.

However, weight limits the portability of a miter saw model. The DWS709 model weighs 51 pounds while the DWS779 model weighs 56 pounds. That means the former is more portable. On the matter compactness, the DWS779 model is more compact-sized than the DWS709. Besides, the DWS779’s dimension measures 2 x 23 x 18.5 inches.

  • The Positive Stops For Miter Cuts

Positive stops come in handy if you want to make miter cuts of various angles. And the two models of miter saws feature this important design. The only issue is that they differ if you look at their positive stops.

The DWS709 model has 13 positive stops. On the other hand, the DWS779 model only has 10 positive stops. This means the DWS709 makes better miter cuts. As such, it’s the winner in this case.

If you usually make more miter cuts. Or you are looking for more room for miter cuts, the select the DWS709 model.

  • Cutting Capacity

First, the two miter saw models by DEWALT bevel to both right and left. But their beveling capacity differs. The DWS709 model bevels 49 degrees to both right and left. While the DWS779 model does so at 47 degrees to both directions.

If you look at the horizontal cutting capacity, you will find a slight difference. The DWS709 model can cut up to 9.5 inches thick materials horizontally. While the DWS779 model can cut up to 9.65 inches thick materials during horizontal cuts.

Some differences also exist in their vertical material cutting capacity. The DWS709 model can cut up to 4.5 inches thick material in a vertical direction. The DWS779 model, on the other hand, can cut a material with a maximum thickness of 6.75 inches.

  • Back Fence Design Cuts

The back fence design of the two miter saw models affect their cutting capacities. And they differ in terms of the dimension of lumber they can cut at 90 degrees and 45 degrees.

For DWS709, you can cut 2×14 dimensional lumber at 90 degrees. And cut 2×10 dimensional lumber at 45 degrees.

But the situation is a bit different for the DWS779 model but in a good way.

That’s because you can 2×16 dimensional lumber at 90 degrees. And cut 2×12 dimensional lumber at 45 degrees. In this case, DWS779 is the winner.

  • Dust Collection Efficiency

Both miter saw models have dust collection management. The only difference is how efficient they’re. The DWS709 dust collection port lets you connect a vacuum cleaner. This improves the dust collection efficiency of the power cutting tool.

But the DWS779 model doesn’t allow you to connect a vacuum cleaner to the dust collection port. As such, the DWS709 model is more efficient at collecting the dust. the winner here is the DWS709 miter saw model.

  • Affordability

The two models also differ in price or affordability. The DWS779 model costs is cheaper than DWS709. That makes it a more affordable option. So if you’re working with a tighter budget, you should buy the DWS779 model.


The two miter saw models are from the same manufacturer. They’re high-performance power cutting tools ideal. When it comes to buying one of the models, you might have a daunting task.

That’s because they pack the same power and have the same blade size. However, they have a few factors that set them apart. And the right model entirely depends on the project that you’re working on.

Choose the DWS709 model if:

  • You’re looking for more portability and smaller projects.
  • You want to have a better dust collection system.
  • More positive stops for miter cuts.
  • More beveling capacity.

And opt for the DWS779 model if:

  • You’re looking for a more affordable miter saw.
  • More horizontal and vertical cutting capacity.
  • You like the compact miter saw model.
  • You’re looking for better back fence design cuts

Always strive to arm yourself with only the best miter saw. And the best miter saw model depends on the project at hand.
