It is a corded electric saw that uses 120 volts. This saw is a 12-inch double bevel sliding compound miter saw which truly tip toes on hold of being to a great degree sturdy but refined and exact. This is an awesome saw for those that need delicate accuracy at work site, additionally require a saw that will be ready to withstand whatever you toss at it.

Carpenters depend on miter saw to aid them do their work quick and exact so as to have a furnished outcome. They distinctly have criteria of choosing which miter saw to use like decisively adjusted, feels common, works solid and smooth, offers extensive cutting limit, and doesn’t measure a ton.

This saw accompanies a ton of positives. As a matter of first importance, the saw is to a great degree well-constructed and strong. The saw comes prepared to utilize right out of the container. This is an advantage for quite a few people as they won’t need to invest energy adjusting it.

Costumer Review

Addition of XPS LED Light makes this a nice improvement over previous model ★★★★★

I’m writing this review not from the perspective of a home contractor or professional, but rather a home handyman / hobbyist. I do not have a huge collection of tools, but previous to receiving this DeWalt DWS780, my “chop saw” of choice was a Dewalt DW703, a 10″ compound miter saw, single bevel. That DW703 has since been replaced by the largely similar DW713. Both saws had a smaller blade, and only a single-bevel with no slide.

Likewise, the DWS780 is replacing the similar DW718. Looking at both miter saws online, they are hard to distinguish except for the addition of the new XPS cross cut positioning system that I will discuss in a minute.

The DWS780 is truly a versatile saw, and you can tell the second you get the box that it is solidly built and not like some of the cheaper off-brand tools you see today. This is the quality you expect from DeWalt, and the saw is ready to be used the second you take it out of the box. Despite having a 15-amp motor and a huge 12″ blade, it is surprisingly quiet, well balanced, and actually reasonably portable. With 1 hand I was able to carry it down to my work room in the basement. I have confidence that I can store and transport this tool without needing to have a permanent bench for it.

Most homeowners do not need more than a 10″ single bevel miter saw. If you are doing flooring, shoe moulding, or other simple tasks, a “chop saw” with a single bevel is all you need. If you are graduating to crown moulding you will appreciate the double-bevel. The saw features clear marks for all angles and bevels, with positive stops for the commonly used angles of 0, 22.5, 33.9, 45, and 49

A Costumer’s Perspective about DEWALT DWS780

First, the light: DeWalt’s XPS Crosscut Positioning System utilizes bright LEDs that are projected on both sides of the blade. This illuminates the work-piece while simultaneously creating a shadow line you can cut to. It’s brilliant. Every saw should have one.
The kerf ends up slightly wider than the shadow line, but it really helps you index to your mark quickly, especially when making bevel cuts where it is more difficult to visualize where the blade will enter the work-piece.
The saw is impressively lightweight (56 pounds) and a well-placed handle makes it easier to carry. It offers very good cutting capacity: 60-degree miters to the right, 50-degree miters to the left, and 13 7/8-in. (advertised) square cuts.

The miter scale is chrome with crisp, etched black angle markings. There is no vernier or micro-adjust knob, but the angle gradations are a full 1/8 in. apart so it is pretty easy to set the saw to cut at 1/2 a degree

The detents feel reassuringly solid, and the detent override located to the side of the miter lock knob allows you an unhindered angle adjustment when you need it.

If you depress the button behind the miter lock knob with your thumb while swinging the saw from side to side, you can glide over the detents, preventing them from wearing out prematurely.

The saw was square out of the box, so no adjustment was necessary. I removed the miter scale anyway to see how difficult it would be to calibrate again. If your saw isn’t cutting square, the recalibration process would begin with loosening the four star screws while holding the miter scale in place, using the onboard star driver/wrench. You don’t need to take them all the way out, but if you do, note that the two near the front are shorter. From the factory, these screws are pretty tight; it helps to stick a nut driver in the onboard wrench to give you some extra leverage. After you get the miter scale loosened so it rotates freely, lock the saw into the 0* detent and nudge it back and forth until it is square, checking both fences as insurance. I like to use a digital bevel square for this. Once you’re satisfied, tighten the screws back up and re-check to make sure the position didn’t change. Overall I think this design makes adjustment easier and more accurate than the Makita, where you have to move the fence to correct for square.

The bevel scale is yellow with etched black angle markings. It measures over 5 inches across, but due to the design of the pointer it is difficult to set it finer than 1 degree. The bevel calibration screw is located in front and to the left of the bevel scale. Turning it adjusts the default position of the saw at 0 degrees (90 degrees to the saw table
The saw required some minor adjustment out of the box, and I have adjusted it several times since, which does make me suspicious about the long-term reliability of the bevel calibration. (Read David Collins’ “Miter Saw Tune-Up” article for more information on miter saw adjustments.)

Changing the bevel-cutting angle requires reaching around the back of the saw to the three-pronged 4-in. cast knob. It’s not the most comfortable arrangement, but I tend to prefer it to the single plastic lever on my Makita.
After I received the saw I immediately changed the blade out for a Freud 80T since I prefer to use Freud blades instead of stock blades. Changing the blade is simple: unplug the saw, loosen a bolt (using the onboard star driver/wrench) in order to slide back the blade cover and fix the guard in the raised position. Next, engage the spindle lock and unscrew the arbor nut, again using the onboard wrench. Reverse the process after installing the new blade. (A rule of thumb I like to remember for blade changes: loosen with the blade rotation, tighten against the blade rotation.)

Out of the box, I noticed the slide action was quite rough. I added some lubricating oil and tinkered with the slide adjustment screw, but my tinkering was to no avail. This is a bummer, especially on bevel cuts where there is added torque on the slide rails while cutting. I suppose the smaller-than-normal rails could have something to do with it, but it just feels like sloppy machining between the rails and the guides.

The other major detriment to this saw is the huge amount of flex in the saw head at full extension—almost a full 1/8 in. in either direction from center. You can’t cut trim accurately when the saw head is flexing all over the place, especially when you’re shaving 1/32 in. off the end of a work-piece. The blade gets “pushed” right off the edge of the board, and makes this common and simple task frustratingly difficult.

I put the saw through its paces cutting poplar trim, AZEK, 2x pine, ash tongue and groove, and oak paneling. Cutting cupped 1×8 oak baseboard on a bevel, the saw visibly struggled, mostly due to the issues mentioned before—rough slide operation and excessive flex in the saw head. As a result, I tried to avoid using this saw for wide, demanding cuts. The 10-inch Makitas and Hitachis that I use track much more reliably.

Dust collection is a challenge on any miter saw, but hooking up a vacuum to this saw does make a worthwhile difference, which is more than can be said for some other saws. I wondered if the light would trigger the auto-start on our Festool vacuums, but it didn’t—the vacuum only came on when the saw motor was switched on.

The base of the saw has a low profile—it sits close to the table when mounted, which aids in keeping the cut station clean by preventing chips and sawdust from building up underneath.

This saw does come with a built-in dust shroud, which can also be helpful.


The DEWALT DWS780 is easy to use,very handy and flexible. It could be adjusted according to length, size and angle.

Keeping That Saw Working Like It Used To

Every carpenter should know that when you buy a new chisel or hand plane it’s not razor sharp out of the box — you have to sharpen it before using it. Well, the same is true for miter saws. They don’t come from the factory in perfect tune.

  • Blade considerations
  • Check the table
  • Straighten the fence next
  • A word about calipers
  • Calibrating the miter gauge
  • A quick check
  • A closer examination
  • Four-cut calculation
  • Adjustment is trial and error
  • Movable fence adjustment
  • Miter scale adjustment
  • 45° Miters
  • Calibrating the bevel


I could see this being a phenomenal buy for somebody looking for a sturdy, skilled, and capable 12 inch miter saw. This machine is substantial, yet keeps up some compactness with a decent stand. On the off chance that you are in the business sector for a miter saw that gives you great worth at the cost, this is a decent saw to take a glance at. You ought to have the capacity to discover it for under $600 in the commercial center. For a saw under $600, this is without a doubt one amazing bit of gear. Add to that a 3 year restricted guarantee from Dewalt, this miter saw is an extraordinary buy.
