- DEWALT DWS780 12″ Miter Saw: My Experience
- NOTE: This model saw is involved in a recall. See my article: DEWALT DWS779, DWS780, DHS790 Miter Saw Recall
I’ve owned a miter saw for nearly 20 years. It’s an essential tool to own for many on the jobsite, for house flippers, and for many homeowners.
My first miter saw was a DEWALT 10″ compound single bevel. It was all I needed at the time and it served its purpose well. There were many times, though, when a 12″ slider would have been great to own. Many of the cuts I needed to make were too large for my 10″ saw, but I worked with what I had.
I eventually decided to sell my 10″ miter saw and purchased a RYOBI 12″ sliding compound miter saw, and the RYOBI universal miter saw stand. The RYOBI saw was great at the beginning, but after dealing with several issues, and the nagging feeling that my DEWALT was much better quality, I decided to eventually sell it.
In 2021, I replaced that saw with one that I consider to be my final miter saw purchase: the DEWALT DWS780 12″ sliding compound double bevel miter saw. Read on to learn about this absolute beast and my experience in using it.

XPS Crosscut Positioning System
One of the best features of the DEWALT DWS780 12″ miter saw is, without doubt, the integrated XPS crosscut positioning system. It’s an LED light you can control with a switch that shines against the blade. The blade itself casts a shadow on the cutting surface and it provides the most accurate cutline I’ve ever seen.
You can see it in action in my Instagram video here.
The lighted cutline is great for both indoor and outdoor use and if you’re indoors, also helps to illuminate the surface area. Direct sunlight on the cutting surface will drown out the cutline. I can see still the cutline but it’s very faint. Personally, I don’t use it while in direct sunlight.
Is the XPS crosscut positioning system necessary to have? In my personal experience, no, it’s not necessary. As I said, I’ve owned a miter saw for nearly 20 years and most of them was without a cutline. The RYOBI 12″ sliding miter saw that I owned previously has a laser line but the accuracy wasn’t great so I never used it.
The cutline provided by the XPS system is very accurate, though. It’s a nice extra and I find myself using it all the time. If you’re looking for a new miter saw and have come to rely on a cutline for accuracy, this is a miter saw that you’ll want to check out.
Miter Saw Stand
If you need a portable miter saw stand like me, there’s two from DEWALT that I’ve personally owned and recommend.
DEWALT Heavy Duty Miter Saw Stand
This is a great, heavy-duty miter saw stand with folding legs that will support 16′ of material.
DEWALT Rolling Miter Saw Stand
The older I get, the more difficult it is to carry around heavy tools and materials. I currently own this rolling miter saw stand from DEWALT (pictured above), and it has been one of my favorite tool purchases ever.
It has a 3-position pneumatic-assisted raising and lowering system and, most importantly, it’s on wheels! This rolling stand is a breeze to roll around and has been a life-saver for my back. It can also be stored in an upright position to save space.
It only supports 8′ of material but that’s ok for me because I have four kids who can assist with longer boards if necessary.
DEWALT DWS780 12″ Miter Saw: My Experience
The DEWALT DWS780 12″ miter saw is heavy duty and is designed for professional wood cutting applications. If your trade involves those applications, you will love this saw.
In all honesty, it’s overkill for the average homeowner like I am now. But I wanted a miter saw that would last and would provide any cut that I could possibly need.
Typical materials I work with and cut often are 2x4s, 2x8s, 2x12s, 1x4s, 4×4 posts, and miscellaneous trim boards. I’ve also used this saw to cut vinyl flooring and pvc crown molding.
My previous 10″ miter saw was dependable and a joy to work with. This one has been that and more. Sure, this saw is expensive. But I just know when I’m cutting that this saw is a heavy-duty beast that will cut with accuracy and dependability. That confidence is worth a lot in my opinion.
