Really bad product a second miter saw I got thinking this one was going to be better than the one I had to return due to failure in the second month......motor stops by itself after starting the cut of a 2x12. Not even 1/4 of the way with anee blade and it stops. Sad.

Well built
Bought a month ago and used to screen in our porch. Used in conjunction with miter saw stand. Made accurate cuts, made me look like a pro, which I’m not even close. Locks up real well, so no chance of slipping up on cut. This replaced my old Dewalt miter saw I had for 15 years and sold it still working like new, only sold because I moved 700 miles. All my power tools are Dewalt, they hold up real well. I have one suggestion for Dewalt, put wheels on miter stand.

Great saw
I had the first generation model of this saw and got a lot of use out of it. Dewalt has made several improvements — the bevel function is easier to use and the dust collection is fairly efficient. This is a great saw, especially mounted on a Dewalt mobile stand.

Excellent Saw
I’m glad I didn’t purchase the other saw I was going to get. I have a number of Dewalt tools and have been very happy thus far. When it went on sale, (DWS779) I couldn’t pass it up. However, due to the store wanting my business and an opportunity to take away a customer from their competitor, I was able to purchase the DWS780 for what the DWS779 was on sale for. SWEET!!!! So happy to be staying with Dewalt!!!

Almost perfect
I've had this for only a week so far and it has performed quite well.
I've heard great reviews about the accuracy of the XPS cutline system and for the most part it is a great feature but the accuracy I feel is slightly exaggerated. I do lots of finishing work and the line it provides is more of a reference point and tends to be approximately 1/16 of an inch off on the left side of the blade but very accurate on the right side.
I've also heard great reviews on the thought that went into developing the dust collection system and it does work pretty good with the dust collection bag.
However if you need to hook up a shop vac to the saw it becomes completely useless, the flexible rubber guides on the intake of the dust collection port get sucked into the opening as soon as the vacuum turns on and completely plug the intake. The only way to make this system work with a vacuum is to remove the rubber guides and once you do that it loses any efficiency in dust collection.
Aside from those couple issues this is an amazing saw that is very easy to use with an excellent cut range. I would definitely recommend this saw to anybody who does not plan on connecting it to a Shop-Vac.

if you buy this produduct they give you free the heavy-duty miter saw stand?
jorge f on Jan 6, 2017
BEST ANSWER: Yes, sometimes. It depends on if they are offering the stand as a free special or not. It will say on the page for the saw if the stand is being offered. The free stand does not automatically come with the saw.
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
Hola tienen de 220v ????
Pepegonzalez1 on Apr 1, 2016
BEST ANSWER: No. 120 VAC/60 Hz only.
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.
Does it have the laser line ?
A shopper on Jan 10, 2017
BEST ANSWER: It uses a light which brightens the cutting deck and casts a strong, thin shadow for a cut line. I like the feature.
I have had the 12" model for 8 years & love it. I have built a new shop with a dust collection unit- is there an adapter for the oval dust port to a circular hose?
jim t on Jan 10, 2017
BEST ANSWER: Yes it is only oval shaped by the blade and has a normal vacuum port on the back.
Looking for case for Dewalt sliding compound mighter saw.

I am interested in this product an I live in the UK. But i need to know if the power outlet is suitable to use in the UK which is 110v on UK building sites?
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
BEST ANSWER: Dewalt puts together the promotions for the item picked for the promotion only.

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 120 days.
