Beware of CPO advertising comparisons
The $210 savings over a regular retail price is not a true comparison for a reconditioned saw. What they don't tell you is that the reconditioned machine does not include a blade for some reason. Buying reconditioned looks like a good deal over new, but when you end up having to buy a blade and the shortened warranty, I'd stick with buying new.

Great tool

Excellent machine!
First use was a 10x14 gambrel shed/barn with a home-made window. Made cutting roof and window angles completely effortless. The free stand is almost as great and important as the saw--easy storage & setup, very sturdy, extendable arms on the ends make cutting long pieces a breeze. These two together are just outstanding- don't know anything they could have done better. The light that casts a shadow of the blade on the work is SUPER. I think this is better than the laser systems I've seen for precisely locating cuts. One of my best-ever tool buys with the stand thrown in.

Best yet 12" compound mitre saw
Great saw for the shop and the field. Perfect for large crown mould. Great for deck construction to cut larger board lumber.

A very good tool.
I've only begun to learn all this tool's capabilities. I use it with the DeWalt stand which I also highly recommend. It's extremely well designed. I'm very happy with both purchases.

Great Saw, Upgrade from earlier models
Buying factory refurbished, saving $100.00 and getting the saw system I wanted makes for a good day.

This unit is replacing a radial arm saw and a miter saw, while taking up less space. This makes my garage workshop more productive and parking my wife's car easier.

I combined the tool with Dewalt's rolling saw stand and got a package that only takes up about 2x2 feet of floor but can be moved around for use with ease.

The saw's LED system makes cutting door casing trim easier and faster. This projects the blades curf on the work material better than Dewalt's older laser system. While speeding the cutting process, it also eliminates adjustments when changing blades.

In addition to giving good miter service, it cuts 2x4s and larger quickly for those projects that always need dimensional lumber.

Great Product: Delivered As Promised.
Overall a great product. The only issue I have found is that you have to remove part of the guide and add a peice of wood in order to put a 45 deg angle on a 1x12. Bottom line is that this is a great piece of equipment and I will be making future purchases from CPO.

Sensational Mtre Saw!!!
Bought this Dewalt Mitre Saw for my son who just got back from 9 months in Afghanistan leading a SEAL platoon. I went to his home to help him set up his woodworking shop in the garage of the house he just rented and this saw was sensational. We were able to easily cut the legs for his work bench and had to cut blocks and shims for his table saw/router table combination, and it was super easy. Great, great, great.

Great Product and Super Service from CPO
This Saw has improve 75% from the previous model although I"m still trying to get use to the XPS light, is not really that accurate but at least it serves as a light and is very convenient at times. Overall I am very pleased with this saw and would recommend it to anyone that is serious about finish carpentry.

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

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.

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.
