Differences : Dewalt DWS779 Vs 780

Engine Capacity:

Engines form the backbone of any hand tool or power tool and miter saws are also no different. Engines are also the one which decides the performance of the tool. So it is better to always look for tools which are powerful and do the work in record time to save energy for future use.

Dewalt dws779 and dws780 is provided with a 15amp motor which is very powerful and can cut through any hard surface with ease. Harder surfaces tend to become difficult to bring them to shape and the miter saws 779 and 780 are very capable to level the surface without much issues.

Both the miter saws are powerful to cut through the surface with sharp edges and that is the difference between which one can judge if the miter saw is good enough or just that in order to save cost the user has bought some random miter saw just for the sake of it.

The primary role of the engine is to provide the required torque to run the machine and cut through the sharp and clean edges easily. Very good device for beginners as well as for experts. Both devices won the race here.

RPM:

When the miter saws are provided with a powerful engine then the role of the speed of the motor also becomes decisive automatically. The speed of the motor is decided by the rotations per minute the engine can deliver. The speed decides how quickly the material can be cut in a clean way without much fuss.

Dewalt DWS779 and DWS780 are provided with 3800rpm. This is really interesting as the rpm is one of the best in the market available but still the miter saw should perform well even though the rpm is good.

The rpm is the one which provides the required torque power to cut through the material faster and also the precision of the cut material depends on the speed of the motor.

Both the miter saws are extremely useful in cutting high density material no matter how the surface is, the cut they provide is world class and are quite clean with sharp edges.

Not much of a difference between the two miter saws in terms of rpm. World class products deliver high class performance is my slogan and Dewalt has indeed made it to the top on its own through such powerful hand tools in the form of miter saws.

Blades:

Every miter saw is judged by how well the blade performs on rough surfaces and how quickly can it complete the work. Dewalt has taken care of them in most of their devices and has not disappointed the crowd in DWS779 and DWS780 products as well. Much to the surprise of everyone the blades are made of solid material and the performance is also good in both the miter saws.

Dewalt DWS779 is made up from stainless steel material which is really good considering the strength of the material itself. One drawback with steel is that it can lead to rust formation sooner than later if not used properly and bringing the blade in contact with water and other liquid stuff.

The blade is somewhat versatile and the work that is required to get out of it is fulfilled, but the user should take care of the abrasiveness of the material as well.

Dewalt DWS780 has overcome the abrasiveness issue by employing the carbide blade along with the steel blade. Dewalt has taken care of the blades issue in this model and is quick to fulfill the customers wish. Carbide blade is very useful as it is free of abrasiveness. The blade is well known for its versatility and durability as well.

Most of the users feel that carbide performs well under tremendous pressure and most often comes out with better precision and accuracy. Of course the accuracy also depends upon the complete device as well along with the blade used. The technology empowered is also very good with the idea of using carbide materials for the blade. Indeed a bold move by Dewalt. DWS780 wins the race here hands down.

Dust collection system:

The main job of a miter saw is to provide good deep precision cuts across edges and surfaces to develop furniture as required by the user.

There is also another important aspect of miter saw is to collect the dust that comes out while aligning the material or the surfaces. Dewalt provides a dust collection system in most of the miter saws it develops and DWS779 and DWS780 are also provided with the same.

DWS779 is a well known model among the masses for the accuracy and stability of the device when the machine is in use with full force. Generally when the user works on the wood surfaces it is known that dust particles are bound to be generated and there should be a mechanism to collect the same.

Also studies have revealed that such dust particles lead to respiratory issues and other health issues. Hence DWS779 is provided with a good dust collection system that would collect more than 75% of the dust it generates while working on the wood surfaces.

DWS780 is also provided with the dust collection system which collects more than 75% of the dust generated from the device. Dewalt had introduced the dust collection system in previous versions of the miter saws and has continued the trend in current models as well with better efficiency to collect the dust. Both the miter saw models DWS779 and DWS780 have won the race.

Guide system:

Guide systems are employed by Dewalt in miter saws and each model is employed with different guide systems. DWS779 and DWS780 also vary in the guide system and this is where the major difference lies between the two miter saws.

DWS779 is provided with a traditional laser guide system which is powerful enough to handle rough surfaces and provide enough light to cut through the surfaces of the material used.

The system is good enough to work on light and heavy surfaces with accurate precision along with cutting of sharp and clean edges. This is what most consumers look for and hence are mostly satisfied with the guide system.

DWS780 is one step higher where Dewalt introduced the XPS system which uses bright LED lights to help the users to work in dark spaces with great accuracy and precision.

With the XPs system the user need not adjust the device each and every time to cut the surface. The LED light produces the shadow which is good enough to cut the surface in a crisp and without much noise coming out of the blade.

One important aspect of the XPS system is how well the blade helps in aligning the device without having to adjust it each time. DWS780 wins the race here.

Dws779

Pros:

15amp motor

3800rpm

Good precision

Cons:

No XPS system

DWS780

Pros:

15amp motor

3800rpm

XPS guide system

Cons:

Very high priced device

Verdict:

After a good research on both the miter saws Dewalt DWS779 and DWS780, it gives an overall idea of both the hand tools and how well they perform. The devices are good in most aspects from blade selection, the engine capacity, speed of the motor and also the durability is very good as well.

One aspect where DWS780 is ahead is in the guide system which is very good compared to DWS779. Pricing wise DWS779 is well priced, but DWS780 is a very high priced device due to the XPs system.

Finally it all comes down whether the user is ready for a system with high precision or the traditional one which is good enough for them.
