Differences Between Ridgid R4222 and Dewalt DWS780

Without further ado, let’s get straight into the detailed comparison of Ridgid R4222 and Dewalt DWS780 to see which one fits your arsenal most:

Miter Saw Type

Generally, a couple of different types of miter saws are available these days to perform different applications. Even though the main purpose of a typical miter saw is to make angled cutting, the application will be varied based on the type.

For instance, the Ridgid R4222 is known to be a sliding miter saw, while the Dewalt DWS780 is a sliding compound miter saw. Although they function almost in the same way, the latter is able to bevel more simultaneously.

In addition to that, the DWS780 consists of an oversized bevel scale, allowing it to confirm easier and more precise angle adjustments.

Feature Differences

There is no secret that every manufacturer has their own perspective and requirement to make a tool, no matter what it is. So there can be some slight differences in their features, even if they perform almost the same way.

Some of the unique features of Ridgid R4222 are as follows:

  • Gets a 1 to ¼” dust collection port for both dry and wet vacuum adapters.
  • It can stop cutting in the middle for a quick transition; thanks to its effective blade brake.
  • 4×6 and 2×12 crosscut capacity at a degree of 45; 4×6 and 2×16 crosscut capacity at a degree of 90.

Now, let’s take a look at the unique specs of the Dewalt DWS780:

  • Able to cut base molding, 2x material, stair tread, and crown molding at the same time.
  • Multiple positive stops with an adjustable detent plate for precision and optimal productivity.
  • Ensures enhanced cutting capacity (vertical), the credit goes to its efficient “belt-drive design.”


RPM usually gives you an approximate measurement of how fast your miter saw is able to operate at a certain time. As a result, anyone can guess the speed range of a miter saw by just looking at the rate of RPM.

So let’s talk about the R4222 and DWS780 now. Both come in a superior motor of 15.0 Amp, but their RPM range isn’t the same. Like, the DWS780’s motor rotates at 3800, whereas the Ridgid R4222 features 4000 RPM, which makes it slightly faster than the Dewalt.

Maximum Cutting Thickness

In short, the max cutting thickness refers to how thicker or deeper your miter saw is able to cut through. As you may know that each of them is popular for their multi-cutting abilities, from 0-degree to 90-degree bevel cuts.

That said, the difference between the Ridgid and Dewalt is noticeable while comparing the highest cutting thickness.

Let’s say the R4222 can make a maximum of 4” cutting thickness. On the other side, the DWS780 is able to make as much thicker as 6.6” to ensure a deeper cut.

Item Weight & Portability

For those who often have to transfer from place to place with their miter saw, it is better to get one that is compact, portable, and easy to carry. There is no doubt that both Ridgid and Dewalt have been familiar as compact tools, still, slight weight differences can bring impact the portability.

Including the battery, the Dewalt DWS780 weighs around 56 lbs in total. On the flip side, the Ridgid R4222 gets a total of 64 pounds of weight, making it slightly heavier than the DWS780.

Range of Price

The difference between these two masterpieces ends in the overall price range! Despite having similarities in a few aspects (e.g. blade diameter, motor, bevel capacity), you won’t get them the same in terms of the price tag.

Compared to the Ridgid R4222, the Dewalt DWS780 is a little steep, probably because of its extended cutting thickness, oversized bevel scale, and innovative gearbox.

Frequently Asked Questions (F.A.Q’s):
