What is the Difference Between a Compound Miter Saw and a Regular Miter Saw?

Angled cross-cuts are made with miter saws. Miter saws allow you to set and cut at different angles while cutting wood. It also enables you to cut your stock both vertically and horizontally. The miter saw and the compound miter saw are the two types of miter saws. The compound miter saw works similarly to a regular miter saw, but it can also do miter and bevel cuts.

While miter cuts are generally used to connect the two ends together at a 90-degree angle, a compound miter saw incorporates a pivoting arm that allows the operator to tilt the saw to other angles. For a bevel cut, a compound miter is preferable. When compared to a miter cut, the ability to do bevel cuts opens up a considerably wider range of possibilities for your miter saw.

There are numerous varieties and varieties of compound miter saws in addition to the typical compound miter saw. Dual compound miter saws and sliding compound miter saws, for example.

The sliding compound miter saw is comparable to a conventional compound miter saw, but unlike a conventional compound miter saw, it has a rail that allows the saw’s blade to slide back and forth. This makes it far more efficient in general, and the DeWalt DWS779 and DeWalt DWS780 miter saws fall into this category.

Trimming and ornamental work are easier with the dual-compound miter saw. Making cuts in both the right and left directions without having to transfer the work piece from right to left is easier with the dual-compound miter saw. It comes in handy and is quite easy to utilize when doing this type of task.

DeWalt DWS779 Review – Let’s dig deep

The DeWalt DWS779 is a dual sliding bevel compound miter saw with a 12-inch carbide tipped blade. This incredible instrument is driven by a 15-amp motor that spins the 12-inch blade at 3,800 RPM. The DWS779 is a dependable and efficient equipment that can cut 216 dimensional timber at 90 degrees and 212 dimensional lumber at 45 degrees. It has a maximum thickness cutting capacity of 6.75 inches.

Both in the left and right orientations, the bevel can reach 49 degrees. It features an over-sized bevel scale that is adjustable, simple to use, and accurate. The DeWalt DWS779 is a well-built, fast, and powerful tool that weighs approximately 67 pounds, making it portable and easy to store. A three-year limited warranty is also included.

The DeWalt DWS779 is ideal for use by a novice at home. Its resilience, on the other hand, allows it to be utilized by a professional on a busy job site. We believe this saw is the clear winner, given that you can easily upgrade your DWS779 to the exact same characteristics as the DWS780 by simply purchasing the XPS shadow technology.

Features of DWS779 - DEWALT Sliding Compound Miter Saw, 12-Inch DWS779)

Features of DWS779

  • Setup is simple.
  • On the DWS780, you may easily upgrade to the XPS system.
  • Much less expensive than the DWS780.
  • Everything was square and aligned right out of the box.
  • For beginners and experienced alike.

DeWalt DWS780 – Difference between DeWalt 779 and 780

The DeWalt DWS780 is a sliding compound miter saw with a 12-inch double bevel. It, too, is driven by a 15-amp motor with a 3,800 RPM speed, much like the DeWalt DWS779 is. It’s a somewhat improved version of the DWS779. As you can undoubtedly guess, the DeWalt DWS779 and DWS780 share a lot of similarities. However, there are a few new features as well. The XPS system, which was previously unavailable on the DWS779, has been introduced into the DWS780 as a significant standout feature. Don’t worry, we’ll go over the new XPS system in detail shortly.

The DWS780 also comes with a carbide blade that is exceptionally robust, a dust bag that uses the same dust extraction technology as the DWS780, and an extra vertical clamp. The DeWalt DWS780, like other DeWalt products, comes with a three-year warranty.

The XPS system shines light on both sides of the blade, casting a shadow on the material to be cut. As the blade approaches the piece, the shadow projection sharpens. The advantage of the LED light’s shadow is that it clearly reveals the exact place of the cut on the material being worked on. Additionally, it will show you how wide your cut will be. The old laser system on the DeWalt DWS779 became out of alignment after a period of time, making the XPS shadow system far more precise. As a result, the extra XPS function aids in making an accurate cut with less effort.

Features of DWS780

The Differences and Similarities – DeWalt DWS779 vs DWS780

Both miter saws are dependable equipment with a plethora of fantastic features that set the industry standard. You’re probably wondering what the differences and similarities are between these two saws in terms of specification. The truth is that these saws are nearly identical, with the exception of the DeWalt DWS780’s XPS shadow technology. The following are some of the most essential features of the DWS779 and DWS780 to consider.

  • CUT

A 12-inch dual sliding stainless steel miter blade is included in both models. However, it is more abrasion resistant than the DWS779 blade due to its composition. A carbide blade is also included with the DeWalt DWS780. Carbide blades are more durable and require less maintenance. Tungsten and carbon, which are denser than other materials, are used to make blades. It performs well in extreme temperatures. It’s more abrasive and long-lasting. DeWalt machines come with a carbide blade as an added bonus.

Both instruments have a significant cutting capacity. It can also do 90° crosscuts of 216 inches and 45° bevel cuts of 212 inches. It has the ability to cut through lumber up to 12 inches thick.

Both miter saws have a double bevel cut feature that allows the user to cut any piece of lumber without having to flip it from one side to the other. It allows you to tilt the blade to the left and right.


The DeWalt DWS780 comes with a brand-new XPS system function. It enables for the projection of a shadow onto the workpiece. It allows for a more precise and accurate cut. This XPS system is also a terrific technique for beginners to gain an edge when it comes to making deadly precise cuts. You’ll never have to worry about low-quality cuts because the shadow cut is always on target.

  • COST

The DeWalt DWS780 is, unsurprisingly, more expensive than the DeWalt DWS779. However, many people believe that the DWS780’s additional technology justifies the higher price. Of course, the added XPS laser system makes the DW780 much more beneficial and efficient to use, but if you don’t need it or are simply looking to save money, the DWS779 would be a better option. Alternatively, you can save money by installing the XPS shadow system yourself and still benefit from the XPS shadow technology.


The motor is a critical characteristic on which the total performance of the tools is dependent. With a very powerful 15-Amp motor, both units perform flawlessly. The blade is rotated at 3,800 RPM by both motors.


DeWalt claims that its dust extraction system will gather 75% of your stock’s loose dust. Both the DWS779 and DWS780 have this function. A little bag that attaches to the dust collection port is included with both saws. Because the bag is small, you may need to empty it frequently, depending on the type of woodworking projects you’ll be working on.

The dust collecting port’s modest size is one of the issues with it. Because of its small size, the dust port on the DeWalt miter saws will not be compatible with an external dust collecting system. We just wrapped some electrical tape around the dust port to thicken it up, and it now works perfectly. Keep in mind, however, that the small bag that comes with it is perfectly adequate, and this was really a personal choice.


A user handbook, a carbide blade, a blade wrench, a user guide, and the miter saw itself are included with both DeWalt miter saws. The DeWalt DWS780, on the other hand, includes all of these tools as well as a vertical clamp.


The DeWalt DWS779 weighs in at 67 pounds. The DeWalt DWS780 is significantly lighter, weighing only 56 pounds. Although this may not seem like a significant improvement, it makes the DWS780 considerably easier to transport, store, and handle. Apart from the XPS technology Dewalt, this is the only feature that distinguishes the DeWalt 780 vs 779. If you aren’t continuously transferring your miter saw, though, this shouldn’t be an issue.


Both miter saws contain a rail lock, which aids in vertical stock cutting, and a cam lock, which aids in angle adjustment and locks at a specified angle.

  • Warranty

The 3-year limited guarantee that comes with all Dewalt equipment is a major plus. Of course, if you take excellent care of these instruments and do routine maintenance on them on a regular basis, they should last a long time.
