Difference between the DeWalt DWS779 and DWS780
Most buyers will probably have already whittled their decision down to between the DWS779 vs DWS780.
The DWS709 is rather lacking in it's cutting capacity despite still sharing a lot of other common specifications and features with the two newer models.
So ultimately you need to understand how the DWS780 and DWS779 compare to each other.
The DWS780 is essentially and upgraded DWS779. That upgrade comes by way of DeWalt's new XPS guide system.
The DWS709 and DWS779 and virtually all other miter saws you'll see from top brands use what is called a laser guide system.
A laser guide shines a laser in line with the miter saw blade to help you determine where the blade will make it's cut on your piece of wood.
The only disadvantage with using a laser guide system on a miter saw is that when you change the blade it can sometimes affect the alignment of the laser which will throw out the accuracy of your cuts.
If you are using you saw a lot like on a job site or in a busy woodworking shop then this may become more of an issue than for a regular home user that may only use their saw occasionally.
The DWS780 uses DeWalt's newer XPS system. The XPS shines a bright LED down the length of the blade. Because the light is projected as close along the blade as possible it ends up casting a shadow where the tip of the blade is.
This results in one of the most accurate alignments by sight that you can have. One of the other advantages is that because the LED is cast along the blade even if you change the blade you will not need to re-calibrate the shadow as it is formed by the new blade.
DeWalt DWS779 Review
The DWS779 offers a great trade off between cutting performance and power and afford-ability.
It is a double bevel 12 inch sliding compound miter saw. It's 15 Amp motor is capable of achieving a maximum no-load speed of 3,800 RPM.
The DWS779 can make miter cuts in a range from 50 degrees left through to 60 degrees right.
Being a double bevel saw it's bevel angle runs in a range of 49 degrees in both left and right directions. There are positive bevel stops at the most commonly used angles of 0, 22.5, 33.9, 45 and at 49 degrees.
Weighing in at roughly 56 pounds it is a pretty sturdy saw. Once mounted to your work bench or on a stand the quality and smoothness of operation becomes aparent.
There are no cheap plastic parts used on any of the elements. The majority of the saw is constructed from precision casted parts that are finished to very fine tolerances. The detent plate of the miter is actually stainless steel which is a lot more robust than you will find on some cheaper brands.

If you are always going to use the saw in your workshop or garage then the best way to both store and use the saw is to mount it permanently to a strong, stable and level workbench.
The workbench needs to have sufficient room behind it to clear the back of miter saw arm. Before you mount it you should move the saw through it's full range of motion before it is connected to the power.
Make sure that you can freely and accurately use all of the features of the saw and that it is at the right height. You don't want it too low so that you are bending over to use it and not too high so that you can easily reach the main handle.
