DWS779 vs DWS780

Dewalt dws779 vs Dewalt dws780
Tool experts have long been familiar with the DWS779 sliding saw by the DEWALT brand. The versatile powered tool found lots of fans among DIYers and professionals. However, the news on its discontinuation and the DWS780 model’s release have provoked certain questions about both products.

Today, we’re going to conduct a thorough DWS779 vs DWS780 comparison. In its course, we will examine their functionalities, main pros and cons, look through the real users’ reviews, and make a list of customer recommendations.

No matter whether you’re an experienced person or a beginner, the review will be useful for all passionate craftsmen.

Main Differences Between the Models

Let us start our DEWALT DWS779 vs DEWALT DWS780 comparison with the main differences we managed to distinguish between the products. The following characteristics may influence your choice all at once, so here they are:

  • The key and almost only difference between the models lies in the precision of their cutting. While the DWS779 product doesn’t provide any supportive functions, the more innovative DWS780 is equipped with the XPS cross-cut alignment system. The technology is based on an ultra-bright LED light that shows precisely where the blade will cut the bar.
  • Consequently, LED lighting also contributes to better visibility of the working surface. The first saw doesn’t have the LED, but you can purchase it separately.
  • Finally, we notice a slight difference in weight. The manufacturer claims that the last modification of the DWS779 weighs the same 56 pounds (like the DWS780). However, users state the first product is about 10 pounds heavier.

1. DEWALT DWS779 12-Inch Sliding Compound Miter Saw

Dewalt_779
View on Amazon

The DWS779 was specially designed to provide both professionals and hobbyists with an affordable yet efficient and versatile sawing device. The first sight and further detailed examination proved that though this model cannot boast of the latest innovative functions, it features several basic and extremely useful characteristics.

So, the DWS779 is a standard sliding miter saw by the DEWALT brand. The tool is portable, which is complemented by rather light construction and two side handles for easy use and transportation.

The main working element is a 12-inch carbide blade. Underneath, we see an exclusive back fence. The fence is equipped with the cam lock miter handle for quick adjustment of the bar’s position for any cuts.

Besides, we note a ruler with degree marking for easy establishment of the most popular sliding angles. The blade itself is also adjustable since you can tilt it to achieve an optimal position.

The combination of the blade and the fence contributes to the cuts up to 2×14 dimensional lumber at 90 degrees and 2×12 at 45 degrees.

The blade design provides a super smooth sliding action. According to users’ reviews, the saw cuts through various materials «like a hot knife through butter» with a 6.75-inch maximum cutting thickness.

However, not only the blade is the reason for such productivity. The DWS779 has a 15amp powerful motor with 3800 RPM. The whole system is corded.

The built-in dust collection system eliminates dust and other particles appearing during the operation. The dust chute and port trap about 75% of debris. The dirt comes into an included dust bag, or you can connect the saw to your vacuum.

When it comes to protection measures, the tool uses a standard transparent plastic blade guard. Also, in the case of any breakage, the manufacturer guarantees a 3-year limited warranty.

Though we noticed some drawbacks, which will be briefly listed in the cons part below and described in detail in the DEWALT DWS780 vs DWS779 face to face comparison section, the positive features of the DWS779 model are fascinating people of various skill levels. Besides, the saw is rather affordable, and the $370 price for such performance is a beneficial deal indeed.

Pros
  • suitable both for professionals and DIYers
  • 12-inch tilted carbide blade
  • transparent plastic blade guard for safe operation
  • back fence with the cam lock miter handle for angle adjustment
  • consequently, the model is suitable for versatile cuts and tasks
  • 15amp powerful motor
  • produces 3800 RPM
  • the dust collection system included
  • portable device
  • affordable option

View on Amazon

The release of the new DEWALT DWS780 model provoked lots of questions among customers. Indeed, the first impression seems to make unnecessary all DWS780 vs DWS779 comparisons. The models look very similar and use the same basic functions in their core. So, what changes do we get then?

Let us briefly note similar characteristics. Apart from the design and appearance, the DWS780 has the same lightweight, portable construction with a 12-inch carbide blade, fence system, and cam lock miter handle.

The same 6.75-inch maximum cutting capacity is combined with the same blade guard protection for both safe operation and visibility. Also, users get the same double bevel cutting system with a tilted blade and adjustable fence.

Thanks to the high-visibility scale and easy angle adjustment, you can apply the tool for various cutting tasks changing the blade’s and the workpiece’s positions up to 60 degrees to the right and 50 degrees to the left. There are 10 positive stops available.

The motor and the dust collection system didn’t change either in this sliding saw.

But what did face great improvements was the cutting precision. DEWALT can hardly boast of a more precise sliding saw in its lines. The DWS780 miter saw features the new XPS cross-cut alignment system.

It allows for avoiding tedious recalibration thanks to an improved ultra-bright LED light. The light casts a laser-like shadow of the blade on the work surface and shows the user precisely where the blade will contact the material.

This unique alignment system saves lots of time and effort on measuring. Besides, you won’t have to worry about recalibration after changing blades.

The unit is also very simple in use, so your skills and experience don’t matter at all. Moreover, the XPS cross-cut alignment makes this model a winner in the DEWALT DWS779 vs DWS780 battle for beginners. LED lighting will help you master the technique and save you from inevitable cutting mistakes and the waste of workpiece.

However, infallible work will cost you about $600 according to the current Amazon price. But who will dare to say it isn’t worth it?

Pros
  • suitable both for professionals and DIYers
  • 12-inch tilted carbide blade
  • transparent plastic blade guard for safe operation
  • back fence with the cam lock miter handle for angle adjustment
  • consequently, the model is suitable for versatile cuts and tasks
  • XPS cross-cut alignment system for more precise cutting
  • LED light
  • No recalibration is needed
  • 15amp powerful motor
  • produces 3800 RPM
  • the dust collection system included
  • portable device
Cons
  • dust collection is not very powerful and tends to clog
  • the blade can go too deep and cut the plastic base if you don’t set the depth stop
  • expensive

Both models have several crucial characteristics that greatly influence performance as well as customers’ choice. So, we believe it’s time to take a closer look at these factors. Without further ado, let’s get to the face to face comparison.

Design and Dimensions

According to the manufacturer's information on Amazon, the DWS779 measures:
2 x 23 x 18.5 inches

the latest modification weighs 56 pounds, though many users state it’s heavier when fully assembled (over 60-65 pounds)

The DWS780 is slightly bigger, but the dimensions don't influence the weight. So, the product measures:
17.72 x 21.46 x 17.13 inches

56 pounds

As we see, the dimensions and even the weight somehow differ. However, when it comes to the sliding saws’ materials and design, the manufacturer keeps to uniformity. Thus, both tools are made of durable stainless steel and aluminum. Some elements, like transparent blade guards and handles, are plastic.

You will also find no difference in their appearances. Brand black and yellow colors dominate in the general palette, adding inimitable and recognizable DEWALT look.

The last thing about the design we’d like to note is the useful carry handles. Since the saws are portable, handles contribute to the ease of transportation as well as allow you to choose and change your working place.

Motor and Rotations Per Minute

Motor and Rotations Per Minute Dewalt dws779 vs Dewalt dws780
DEWALT DWS779 and DWS780 are corded tools that work from a common outlet. Their motors are identical and require standard 120V.

The motor is 15amp and produces 3800 RPM. This power is enough to cut the majority of materials, including wood, plywood, gypsum goods, laminate, etc.

Unfortunately, engineers didn’t provide the motor with some overheating protection systems. However, even without these additions, it is quite durable, doesn’t lose power over time, and doesn’t exceed the required noise level.

Verdict: Motors are a worthy pride of the saws. Considering that they belong to the middle price niche, such power and rotation data exceed expectations and satisfy even experienced professionals.

Blade and Position Adjustment

Blade and Position Adjustment DewaltThe blade used in both powered tools is a 12-inch carbide blade with 60 teeth. The original element is designed for cutting wood and its derivatives, but users can purchase and install other discs for different types of materials.

The adjustment system is also one of the coinciding functions of the two saws. It is called the dual bevel where the blade head and the fence can change their tilt and angle for a more precise cut. The saws provide 60 degrees to the right and 50 degrees to the left. Both have convenient metric rulers, and the miter detent plate offers 10 positive stops. There are positive stops at 0 degrees, 22.5 degrees, 33.9 degrees, 45 degrees, and 49 degrees in both right and left directions.

The back fence and cam lock miter button also contribute to the ease of cutting. Thanks to the latter, you can lock angles between detents. The back fence cuts up to a 2×16 at a 90-degree angle and 2×12 at a 45-degree angle.

Verdict: In a short word, we can state that the saws come with efficient and durable blades. The combination of this sharp cutting element and powerful motor leads to easy, smooth sawing. Besides, numerous latches and clear position options support the most often needed angles, which means the sliding saws will turn into versatile tools in your kit.

Cutting Precision Improvement

Cutting Precision Improvement DewaltAs we’ve stated right from the start, the DWS779 has nothing to boast concerning the precise sawing. It doesn’t come equipped either with lasers or with any other technology. However, the DEWALT allows you to purchase them separately and install if needed.

Here, the DWS780 is not similar to its brother. This is a much more precise model thanks to the XPS cross-cut alignment system. Its work is based on LED lighting. The unit both lights the working surface and backlights the blade, making it cast a shadow on the workpiece. The shadow falls right on the place where the blade will cut the material. Thus, necessary marking is performed.

However, any system that can increase the speed and precision of cutting is welcomed. So, the XPS proved to be much more efficient than one would expect from such a simple technology.
The DWS779 is also compatible with the XPS system, and you can buy the components for this saw.

Verdict: Please mind that the light’s greatest benefit is not for making straight cuts, but for mitered cuts for you to see where the blade will fall at the side of the workpiece. Kerf line won’t be seen that well with the light when the saw is running. Also, the shadow is only visible enough to be used a few inches from the bar.

Dust Collection

dust chute and port Dewalt dws779 and dws780
Both tools come with a plastic dust chute and port. The system turns on automatically together with the saw. Thus, the generated suction traps the produced debris instantly and non-stop.

Unfortunately, we didn’t see the perfect dustless operation as the power is enough to pick up about 75% of particles. Dust goes into a dust bag. If you have a vacuum, you can easily replace the bag with it to both increase suction and dirt capacity. The port fits standard hoses.

Verdict: Users claim that the port is not very efficient, since it easily gets clogged. The suction also misses too big particles and dirt on the table and under the blade. Nevertheless, dust collection greatly improves work quality and convenience since even the minimum elimination of flying particles increases visibility and safety.

Safety Systems

Like all saw manufacturers, DEWALT has equipped its DWS series products with mandatory safety elements. There aren’t many of them, which prevents these models from getting the names of the safest.

So, a blade guard is the main and the only safety equipment presented in both sliding saws. The guards are made of transparent plastic that covers the rotating disk during the operation as well as in non-working condition. Not only does it protect you from direct injuries, but it also prevents particles from flying all over the room.

Transparent design is supposed to provide you free visibility and control over the process. However, since the plastic is dark, we didn’t feel 100% confident.

Verdict: The guard is nice and necessary protection that turned out to completely fulfill its functions. Still, we lack the safe stop buttons that could immediately stop the tool in case of an emergency. Similar units would help beginning craftsmen feel safer.

Accessories

DEWALT DWS779 comes with:

Dewalt_779

  • 12-inch 60 teeth carbide blade
  • blade wrench
  • vertical material clamp
  • dust bag

DEWALT DWS780 comes with:

Dewalt_780

  • 12-inch 60 teeth carbide blade
  • blade wrench
  • vertical material clamp
  • dust bag

As you see, the kits are identical. Customers get the minimum of necessary equipment, so if you were planning to find additional blades, knives, etc., we’d have to disappoint you. However, the beginning master has everything he needs for his first works while a professional can easily complement the tool with numerous accessories available.

Please pay special attention to the fact that being portable, these sliding saws do not come with stands or tables. In case you need some, DEWALT offers affordable and universal stands that are sold separately.

Guide – How to Choose the Best Sliding Saw?

A sliding saw is a much more versatile powered tool than one may think at first. They are irreplaceable for all carpentry workshops producing door and window frames, furniture, wooden goods, etc. Moreover, house owners will also find regular application for them. Minor local repair works like cutting of lining, baseboards, baguettes, pipes, floor laying are tasks for a sliding saw.

If you want your purchase to bring as much benefit as possible, you should pay attention to several crucial characteristics. Let’s briefly discuss the main of them.

Blade Position
The cutting head with a built-in blade is the main working element of the tool. In the majority of models, you will push the head. However, some saws locate a rotating disk in front of the user for better visual control and more comfortable work.
Gear and Belt Drive Models
The saw blade rotates as a result of the engine running and the gearbox engaging. There can be two modes here, each of which has its pluses and disadvantages.

During the gear tool operation, the saw eliminates the possibility of slippage. However, the belt drive transmission produces less noise, and the disk almost doesn’t vibrate. On the one hand, belt drive models save the engines. But on the other hand, the belt wears out quickly and becomes an obligatory consumable expense. So, here the choice is yours.

Fence System and Bevel Adjustment
All sliding saws allow users to adjust the position of the bar in relation to the blade. Basic tools are equipped with a single bevel system where the working surface can be rotated only in one direction. More expensive and professional-level tools come with dual bevel. It means that the fence changes its angle in both directions.

Dual bevel with left and right angle adjustment is important if you deal with workpieces of complex shapes and large sizes.

As a rule, the angle of adjustment in each direction is 45 degrees. It can be 50 and 60 degrees. Anyway, there are lots of options here, that’s why your special attention is required. The final choice will depend on your needs.

Disk
Sliding saws are mostly used for works with wooden goods. But with the disk replacement, you can also deal soft metals, plastic, gypsum items, etc. Some saws already include several disks in their kits. If you choose a more budget option, you will still be able to purchase additional blades.

Besides, the number of teeth and the disk size also significantly influence the operation. The diameter will change the cutting depth, while the speed and smoothness of sawing depend on the teeth.

Rotations Per Minute
The number of rotations, or the idle speed, is another criterion of exceptional importance. The higher this characteristic, the better and smoother the cut will be. Moreover, if we talk about the professional use of the tool, it is desirable that the saw has the ability to adjust the RPM. A good sliding saw will provide from 3200 to 6000 RPM.
Safety Measures
Since you are dealing with a sharp cutting tool, don’t forget about safety systems. The more, the better. A protective cover or blade guard is a compulsory element. Manufacturers also provide a soft start, safe stops, a lock for replacing the blade, an automatic shutdown if the equipment gets stuck, and many others.

These modern systems make the tool operation not only convenient but also safe.

Laser Marking
Modern models are equipped with a laser. The user sees the cut line, and there is no need to measure it manually each time. Such technologies increase the saws’ price, but they also reduce the preparation time, which is worth paying for.
Dust Collection
The dust collection system can be organized in different ways. In some models, sawdust is collected in bags, while in others, a vacuum cleaner is attached to the tool nozzle, which is certainly more efficient.
