Summary: I was a little nervous after reading reviews claiming sticky slides. My DWS780 arrived in a beat-up box, but the saw was perfect when it came out of that box. Perfectly in square, both bevel and miter. The slides run as smooth as silk, not the slightest catch or crunch. I was prepared to buy a replacement blade right away, as the blades on new saws are often junk, but the 60 tooth finish blade produced cross cuts with a surface like glass.
Summary: It is the best Compound Miter Saw I have had, the angled cuts are accurate and clean. I like the XPS system it uses for lining up the cuts, not only it is accurate it also provides nice light for the cutting area.
Summary: I really like the saw. I bought it to trim the interior of my house. Out of the box, the saw I received was not square in either plane. Spend about an hour truing the saw before jumping into your first project. For interior trim, the stock blade will not be the best option, however, for general framing, it will work great. I changed the stock blade for the 96T. Although a little dim in the brightest daylight, the aiming light is a great help.
Summary: I purchased this machine as an upgrade to my 12" Delta miter saw. The Delta did not have a sliding blade, and I was limited to the width of a board I could cut on it as a result. The Dewalt's sliding mechanism has provided all of the capacity that I've required to crosscut rough stock before it goes to the jointer.
Summary: High quality product... works great. The light on the blade is wonderful. Better than a laser because the light is on both sides of the blade casting a shadow on the object to be cut EXACTLY the width of the blade and exactly where it will cut. Also purchased the rolling miter saw stand and the two combined are my new favorite tool around the property. Bravo DeWalt!
Summary: Loaded with features, widest range of cut angles I've seen on a miter saw (roughly LH ~50 deg. / RH 60+ deg), smooth action, soft start, and lots of attention to design details. Dust collection doesn't work the greatest, but compared to other miter saws, not bad. Repeatability and precision are much better than my old Ryobi 10", and with the DWS780 LED, alignment to the cut mark is a breeze.
Summary: It would have a higher rating if there was an easy way to get repairs. On the third time of use, the guard flew off and now cannot be reattached. As far as we can tell, the entire 50 lb saw must be mailed back to manufacturer. Cannot use the saw w/o the guard unless one wants to lose a digit or two!
Summary: Overall this is a great saw. Has the feel of a well built tool. The light that shadows the blade is great. I had to make minor adjustments after it was out of the box which was nice. I will chime in on the one improvement that does need to be made and that is the rails for the slide. The saw doesn't slide as smoothly as some of the competitors, but it is still one of the best out there.
