Performance
The 15 amp motor turns a 12 inch blade at 3,800 RPM, which is standard for the class and plenty for framing lumber, deck boards and hardwood trim. The headline number is capacity. Cutting a 2x14 at 90 degrees means a single pass through a wide board or a 1x12 shelf, and at 45 degrees a 2x10 crosscuts cleanly. An independent review by ProToolReviews also notes that a removable back fence allows deeper cuts of about 16-1/8 inches on 1x material at 90 degrees, which is handy for wide shelving and panels.
Blade choice determines finish quality far more than motor size. The stock blade is fine for framing and rough carpentry, but if you cut trim, casing or hardwood you will want a fine-finish blade with 80 to 100 teeth. A 100-tooth 12 inch DeWalt blade lists for about $66 on Amazon and is the single best upgrade you can make. With a good blade, a slider of this class can produce cuts ready for paint or stain, provided the saw is set up correctly.
The XPS Cut Line
The feature most owners point to is the XPS LED shadow line. Instead of a laser that can drift or wash out in daylight, the saw projects a shadow of the blade onto the workpiece, so you line up your pencil mark with the shadow and cut. One independent review notes it stays accurate when the saw is bumped and remains visible in sunlight, and DeWalt says it needs no calibration. For anyone cutting trim on a jobsite or in a garage with bright windows, that is a real advantage over a laser.
Design and Build
The DWS780 uses dual horizontal steel rails, and an independent review reports they resist flex during 45 degree bevel cuts. The trade-off is footprint. Because the rails extend behind the saw, the DWS780 needs clearance from the wall, which is a problem in small shops where the bench sits against a wall. If that is your situation, read our comparison of the Makita LS1019L vs DeWalt DWS780, because the Makita is designed to sit flush against a wall.
The fences are tall and slide out of the way for bevel cuts. They support crown molding up to 7-1/2 inches nested and base molding up to 6-3/4 inches vertically against the fence, which covers most residential trim. The miter range is 50 degrees left and 60 degrees right with 10 positive stops, and the fold-away bevel stops at 22.5 and 33.9 degrees speed up common crown cuts. At 56 pounds it is portable enough to carry to a job, though most owners will want a stand. DeWalt's DWX726 rolling stand lists for about $299 on Amazon, and the ProToolReviews write-up describes the saw and stand combination as bulky to store.
Dust Collection
DeWalt claims the DWS780 captures more than 75 percent of the dust it generates, and the manufacturer's dust collection system includes a bag. One independent review reports the long dust tube can clog easily. As with every miter saw, dust collection is a partial solution: connect a shop vacuum and expect to wear a mask and glasses regardless. If dust control is your top priority, no saw in this class will make you fully happy without an external extractor.
Value for Money
On Amazon as of September 29, 2026, the DWS780 lists at the current retailer price, with an additional $50 instant discount offered on approval for the Amazon Visa card. It is sold and shipped by Amazon.com with a 30-day refund and replacement window. For a saw that cuts a 2x14, holds crown molding upright against the fence, has an accurate shadow line and carries a 3-year warranty, that is a fair price.
The alternatives shape the decision. A 10 inch slider costs the same or more and gives up capacity. A cheaper 12 inch slider from an off-brand may cost a third as much but usually lacks the rail quality, the cut line and the service network.

Who Is the DeWalt DWS780 For?
The DWS780 suits deck builders, framers, trim carpenters and serious DIYers who need one saw to cut wide boards and large molding. It also suits homeowners planning a big project, such as a deck or a whole-house trim job, who would rather buy the saw they will not outgrow. It is less suited to small shops with a wall-hugging bench, buyers who want soft start and an electric brake, or anyone cutting only occasional 2x4s, for whom a smaller and cheaper saw is enough.

Verdict: 9.0 out of 10
The DeWalt DWS780 earns 9.0 out of 10. It gives you the capacity of a full 12 inch slider, one of the most accurate cut line systems available and a 3-year warranty, at a price that undercuts many rivals. It loses a point for the footprint its rails require, average dust collection and the absence of soft start and an electric brake. For most buyers it remains the best 12 inch miter saw to start with. Check the current price on Amazon, since promotional pricing on this saw changes often.
FAQ
What can the DeWalt DWS780 cut?
It cuts a 2x14 at 90 degrees and a 2x10 at 45 degrees, crown molding up to 7-1/2 inches nested and base molding up to 6-3/4 inches standing vertically against the fence. Miters are 50 degrees left and 60 degrees right, and the saw bevels in both directions.
Is the DeWalt DWS780 worth the money?
For most buyers, yes. It lists at the current retailer price on Amazon with a 4.8 star rating from more than 2,500 owners, a 3-year warranty and best-in-class capacity. Occasional users who only cut 2x4s can save money with a smaller saw.
Does the DWS780 need a stand?
It is not required, since the saw weighs 56 pounds and can sit on a bench. Most owners add a stand such as the DeWalt DWX726 for jobsite work, but a stand adds cost and storage bulk.
What is the XPS light on the DWS780?
XPS is DeWalt's LED shadow line system. It projects the shadow of the blade onto the workpiece so you can line up a cut mark, and DeWalt says it needs no calibration. One independent review reports it stays accurate when the saw is bumped and stays visible in bright light.
Should I upgrade the blade on the DWS780?
If you cut trim or hardwood, yes. A fine-finish blade with 80 to 100 teeth leaves a cleaner cut than a general-purpose blade. For framing and rough carpentry, the included blade is adequate.
