Describe Yourself:
Perfect saw for all your needs
After using a Dewalt miter saw that only turned 1 way and didn’t angle I knew I needed an upgrade. I bought this saw and instantly satisfied with its performance. It has Turned things around for me. It has increased my productivity and the cuts are perfect every time. I would nightly recommend this saw for anyone in the contracting profession. It’s versatile from framing to fine wood working.

I. Love. This. Saw.
I named her Hazel because she works hard. My first miter saw was the brand of a big box store. Never could I have imagined how much better a tool this was for a little more money. She is accurate, great features and SOLID! Because of this saw I purchased a table saw and circular saw from DEWALT and am looking at drills and drivers.

Fantastic buy
Bought this about a month ago to replace a smaller, older saw of a different brand.
I have not been able to put this to the test too much yet, but no disappointment so far. I’ll revisit my review after much more use. But the quality is excellent and all around a fantastic buy.
I was a little concerned at first after reading a few reviews and speaking with a friend about damage and missing seals upon unpacking. But I think that’s all because of the stores in which they were bought, as if the saws had been removed by them and perhaps put on display and repackaged. I just made sure to buy one with the outer plastic wrap still intact and no issues.

Workhorse saw for every use!
This saw has a ton of power and lots of nice features. I have used it for everything from chopping two 2x4s for a dog bed, to finely tuned and precise miters for fine furniture and moulding. A great workhorse saw for any purpose.

This is a game changer!
I bought this saw over a year ago, and it has dramatically improved my work. The saw is accurate, powerful, easy to adjust, easy to operate, and handles whatever I throw at it.

I have this paired with the smaller portable stand, which I think is a must have.

Workhorse of a Saw
This is an amazing saw. I purchased it mainly because of the massive 16 in cut capacity and it delivers. Makes quick work of 2 X 12s, large chunks of play wood, and trimming up doors. I was skeptical of the light shadow guide, but it is very accurate. People say its hard to see on a sunny day but I've never had a problem with it. Put it on your mark and cut. Best saw I have ever used.

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.
