A little early yet for a full review
A little early yet for a full review, only used it for one day, but wow! I previously had a 10" old mitre saw, this thing knocks it's socks off. I'll re-review it after a little more use. Also bought the DWX723 Stand for it as well, with my old knees, it's a dream to work on the saw standing up instead of crouching down continuously.

Describe Yourself:
Consistent Performance
I've owned this saw and stand for over 2 years now and am impressed with its capabilities and consistent performance. I have renovated 2 houses, moving the saw and stand frequently. Back to the home shop for fine woodworking. Its accuracy is dependable. Check your set up, fine tune if needed, and it will not go out of sync. It works!

I bought this for a complete basement remodel. I haven't found anything yet to slow this machine down. It works amazing smooth slide. It is very heavily built and super solid no slack anywhere.

Definitely one of the best tools in my shop. I use it for almost every project. When I bought it a few months ago it came with a stand. Dewalt has a reputation for quality and they do cost a little more than other brands but well worth it.

Great saw!
Purchased this saw a couple years with the stand and use it daily. Easy to adjust, replace blades, etc. I sometimes travel with the saw and can easily detach from the stand and carry each independently.

The only saw you need!
From job site to hobby garage, this saw does it all. I bought this a few weeks ago and have been impressed with the capabilities it has. Whether I'm cutting pressure treated 2x12 or 6" oak crown molding, this saw does it.

What is the big difference between the 780 and the cheaper 782?
ziggy on Sep 18, 2014
BEST ANSWER: I just called DeWalt. The 780 has the lighting system built-in, the 782 does not. Also, some retailers include the $199 stand bundled with the 780.
I am considering purchasing a 12" Dewalt mitre saw, MODEL (#DEWNDWS780). Could you tell me what "DEWN" that precedes "DWS780" stands for? "Thank You"
Scott on Jun 12, 2016
BEST ANSWER: I have no idea unless it is a specific model designation. GREAT Saw! but
would recommend buying the cart that comes with it or waiting until the
cart is free. Saw is very large and takes up a lot of space, but
can you add laser beam to dewalt DWS 780 or recommend another saw
Rick on Mar 4, 2013
BEST ANSWER: why would you want to? The shadow system shows up even in direct sun as I recently found. the shadow system is always indicating blade location, while lasers are independent from blade and must be readjusted for each blade.
Could I saw cement patio pads ?
A shopper on Jun 16, 2019

Are you offering this saw with the free heavy duty stand with purchase still?
N on May 2, 2015
BEST ANSWER: We are not currently offering the free stand with miter saw purchase promotion.
Can the depth of the cut be adjusted to stop and stay at that depth of cut. I want to be able to make a mortise. The older model of this saw was able to do this, will the dws780 also be able to do the same?
If it will, thats the saw for me.
Michael on Jan 16, 2015
BEST ANSWER: Yes, this item may be adjusted to stay at a level cut.

Woody on Nov 28, 2015
BEST ANSWER: The Dewalt dws780 would need a step down converter to use in the UK.
I am still trying to find out if I order this saw can I get the DWX726 stand instead of the statioary one offered since the price is the same?
DON on Oct 13, 2015

DON on Oct 12, 2015
BEST ANSWER: The current promotion can only be used with the folding stand.
What is the difference between a Double Bevel Sliding Miter Saw and a Dual Bevel Sliding Miter Saw?
David on Sep 18, 2015
BEST ANSWER: Double Bevel and Dual Bevel is the same,just different terminology.
Just bought the DWS780 because it is considered to be Dewalt's best and newest miter saw and I have always trusted Dewalt's quality. The truth is, I never would have spent $600 on this saw if the $200 stand did not come with it. I have not used the saw yet but I am finding that the glider feels very smooth. Is that because i am not cutting wood with it or did i just get a saw that was made better than many others are complaining about? The saw I was going to buy was the 716, 12" without the slider for $349. I paid $600 for the slider but if the slider is an issue, maybe it needs to go back to the store. Any ideas if corrections have been made to this saw gliding system or am I just lucky?
Bob on Sep 15, 2015
BEST ANSWER: Please contact the manufacturer direct at 1-800-433-9258 for technical assistance.
Are you shipping type 1 (made in Mexico) or type 20 (made in Tiawan) ?
Glass on Jul 9, 2015
BEST ANSWER: The DWS780 type is printed on the saw, it is no longer printed on the outside of the box. I know from previous orders that I have placed with customers, that the type was 20
Can you add a laser light to saw
Heil on Jan 29, 2015
