A miter saw is a must-have tool for not only the professionals on the job, but also for creative hobbyists looking to fix up their newest venture. A saw can make all the difference between an amateur job and a clean, precise finish that no one can complain about. Miter saws have the best features to combat the problems faced by woodworkers on the daily, and therefore are one of the most mulled over decisions in the shop. A good saw will give you not only precise cuts but will also raise the accuracy and the safety value of your business.
Versatile machines that fit every need of the hour to challenge the productivity levels to rise even higher; this is the kind of motivation we’ve seen from Dewalt over their past few years. They have earned their name in the trade through extensive research and experience, to provide state of the art designs and functionality. Their miter saws are no different; they live up to all the expectations put up against them.
DWS779 and DWS780 are two models by Dewalt that are made to give you the best that the brand has to offer. DWS779 and DWS780 are two different types of Miter saws that come from the 12-inch sliding double Bevel saw tool class. There is a distinctive upgrade from the traditional radical arms saws and chopping machines in their sleek design, which makes these miter saws more advanced and versatile, the perfect addition to any person who deals in the art. These are a must-have for every professional, and if you’re looking for a heavy-duty miter saw, by all means, go ahead and purchase either the DWS779 or the DWS780. They are the current best miters available in the market with their unmatched quality, accuracy, and ability. It goes without saying that Dewalt’s commitment to safety should not be missed, as well.
The DWS779 and DWS780 are extremely similar to each other on first observation, but on closer observation, you would notice the differences that earn them the distinction. They each have unique features that differentiate them a great deal from the other.
We have compiled a list of different aspects of the two models to outline the reasons why one may stand above the other. These two are fundamentally similar; the DWS780 is an upgrade of the other; it succeeded the DWS779 in terms of technical support. As a result, it boasts of advanced features as compared to 779. The differences are centered around the price, the cutting mechanism, and mainly the XPS system. However, both are fully equipped with all the elementary features that are a prerequisite for a good miter saw.

DWS779 is more affordable due to it being the building design for the more advanced 780. It cost around $469.00, whereas the DWS780 is more expensive costs around $599.00, depending upon the site you use. The change in price is due to the fact that the DWS780 is a bit more advanced with more features. It does not mean that the 779 is a waste of your time, since depending upon your work style, the 779 may very well translate into value for your money.
Here is where the major difference between the two models comes into light. The biggest factor that distinguishes between the model 779 and 780 is that feature that the DWS780 model is equipped with the LED light alongside the blade to help in making cuts. Whereas the DWS779 has an XPS light installed for the same purpose. The DWS779 has a cut-line blade positioning system, which can help you to adjust the system easily. This enables the user to have a free-cutting line indicator, which helps in increasing accuracy. Many people have indicated that they prefer the LED system over the laser one. This may be due to the fact that while the LED light always remains properly positioned, whereas the laser systems can be skewed out of position while setting it to cut. In addition to this, the LED light casts a shadow line of the teeth of the blade over the stock, which makes it easier to have precise cuts.
The guide system is the major difference between DWS779 and the DWS780 model that will strike you. While the first one uses a more traditional approach towards the woodcutting,the laser guide system is still reliable. The DWS780 has the XPS system, which includes an LED light that shines alongside the length of the blade. This technology makes it so that the miter saw can cast a shadow line that changes with the movement of the blad
The second important difference is that the DWS779 is heavier, weighing in at around 67 pounds, whereas the DWS780 is lighter in weight, at 56 pounds. Weight is an important factor while considering the transportation of the saws, so if you are in a business that moves around a lot, you might want to think about getting a lighter model.
MITER DETENT PLATE
Considering the miter detent plate, parameters regarding the two models are also one of the more noticeable differences between these two. The DWS780 saw miter come equipped with a stainless steel plate with a cam lock. On the other hand, the DWS779 boasts of a stainless steel lever cam marked with ten positive stops. In addition, the DWS779 has a double horizontal rail with a clamping device. The linear ball bearing technology makes your cuts more accurate and up to the mark.
In its own stead, the DWS780 has a rail lock. This improves results from vertical cutting. For locking the angles and angle adjustment, the device has a cam lock miter button.
The Motor determines the overall quality of any work you will pick up with the tool. It is the lifeline of the saw and therefore determines how long will the saw perform. While comparing any miter saw, it is vital to give more than just a cursory glance towards their engines. By taking into account the size, power, and dynamics of the motor, you can make accurate decisions regarding which saw will work better for you, depending upon the project and the user. If you are a hobbyist looking to work on lighter materials, a heavy-duty motor may actually do more harm than good.
Both models, the DEWALT DWS779 12″ Sliding Compound Miter Saw and the DEWALT DWS780 12-Inch Double Bevel Sliding Compound Miter Saw, come with a 15 amp motor.
This engine will give a considerable boost to the blade attached to the saw. Mounted directly atop the shaft, which rotates the disk, a motor of this capability will provide the torque needed to rotate the circular saw, gathering up spin up to a no-load speed of 3800 RPM. At this speed, the saw can make cuts quickly and efficiently. This is an important aspect because this is a prerequisite in almost every type of stock you will work with, Sharp and clean edges are the marks of distinction between a project handled with a low-quality miter saw and a good one.
The kick that this motor provides is enough to go through the cut motion once to get the job. It eliminates the need for moving the lade time and again through thicker materials, which means that the possibility of making mistakes is taken out of the question.
Since the same engine technology is applied in both miter saws, there is no greater distinction to be made here, between the DWS779 and the DWS780. You can place your trust in both tools and get the same reliable motor capacity with it. The work quality that it gives to the overall performance of the circular saw will be consistent in both.
The blades that come with both the machines have the stainless steel miter plates that weigh nearly 60 pounds and have 12-inch blades to use. The difference that you just take into account with respect to blades is given below.
The DWS779 model comes packed with the steel blade, while the DWS780 also puts in a carbide blade. Carbide blades are a blade built-in tungsten carbide, the chemical compound that is an alloy of tungsten and carbon. This makes the material considerably denser than other metals and substances that blades are usually made of. Carbide blades are broadly known for their versatility and durability. This refers to the fact that carbide is a nonabrasive material, and will not take up scratches with heavy use or break apart under extreme tension. The material is also resistant to higher temperatures, so you can use it for longer hours without worrying about molding the blade or breaking it in half, even at the highest possible speed.
Most of the time, users feel that carbide tools have better performance while making cuts since the finish is usually very clean and smooth at the same time, and it leaves sharp edges.
Carbide blades are preferred today due to their high shelf life. These blades remain sharp even with daily use. Practically impossible to bend, they provide clean cuts every time you put them yo work.
The models each provide excellent quality in terms of their design and function. There are a few factors that differentiate one from the other and can make all the difference between the work output depending upon your comfort level and experience. That being said, the price margin between these two is also quite large, and it amounts to the use of the XPS light system that comes with the 780. If you believe that the guiding system is one to consider heavily, the 780 is a go-to choice. However, the shadow system does not fare well in settings where there is ample light bouncing off al directions, such as the sunlit backyard. If your work is centered around the outdoors, you may want to stick with the traditional laser system. Or, if you believe that the laser works just as well for you, there is no reason to shell out extra dollars for another system.

FAQ (Frequently asked questions)
1. What is the height of the cutting deck from the table?
The height of the cutting deck from the table is around 2-1/2-3 inches from table to the actual flat surface of where the blade meets the deck
2. Can XPS be added, i know Dewalt makes a kit to add it to some saws, but this model was not listed?
The model can be altered to fit the XPS light atop for better accuracy; however, after watching the process, it looks like the end result requires too many modifications to boot. You would be better off with the 780 itself if the laser light is not of your taste.
3. Is this model part of DeWalt’s Built-in USA program?
Yes, the model features under Dewalt’s built-in the USA program.
4.How to get 16″ crosscuts. Do you have to remove the fences? With fences seems it will only go 13.5″?
Yes, you remove the fences to get cuts that will go as deep as 16 inches. The guidelines for how to remove the fences are present as a set of instructions in the manual.
5. Does dual mean can also plug into extension cord and outlet? Not just battery operated?
No, this is corded power only. The dual/double bevel indicates that the saw can bevel both left and right.
6. How do you install crown molding stops on a Dewalt 716 miter box?
The crown molding stops for the DeWalt 716 miter box come complete with two wingnut type bolts. These bolts and stops fit agency on both sides of the fence. Or, one wingnut bolt and stop on each side of the table base (same difference).
7. Does anyone else have problems engaging the pin that locks the saw in the down position? The pin won’t slide in on my new saw.
There is a depth stop on the right side of the saw that has to be flipped back to allow the saw to go down all of the ways. If you are still confused about how to achieve this, the instruction manual has a set of instructions dedicated to the purpose.
8. What vacuum adapter fits DWS780 miter saw?
The vacuum adapter is a strange size, and the only possible solution that we came across was to use a rubber hose with two clamps. However, Dewalt does offer vacuum solutions that act as attachments on their site.
