Last reviewed: September 22, 2026 · Editorial cross-check against current manufacturer service documentation, SKU spec cards, and shared instruction manual specification tables. A prior version of this article reversed which model includes the XPS/CUTLINE LED shadow line; that factual direction has been corrected in this review pass.
Quick Verdict
The DeWalt DWS782 and DWS780 are very similar 12-inch double-bevel sliding compound miter saws. The key difference is that the DWS780 includes DeWalt’s XPS/CUTLINE cross-cut positioning system, while the DWS782 is the lower-feature version without that factory cutline light.
Choose the DWS780 if accurate cut-line visibility matters — trim, crown molding, finish carpentry, repeated precise cuts.
Choose the DWS782 if you want similar sliding-saw capacity for less money and can live without the cutline system.
If you are already cross-shopping the 12-inch sliding DeWalt tier, read our Ridgid R4222 vs DeWalt DWS779 12-inch miter saw head-to-head first to understand where these two sliders sit relative to adjacent 12-inch options. Both the DWS782 and DWS780 use the same 15-amp / 3,800-RPM motor, the same 60-degree-right / 50-degree-left dual miter geometry, the same 0-49 degree double-bevel design, the same tall sliding crown fences, the same 2×16 at 90 degrees / 2×12 at 45 degrees sliding cross-cut, and the same dust-port class. Outside of the XPS/CUTLINE factory LED on the DWS780 and the resulting street-price gap, the two saws are interchangeable frames — this is a feature-tier decision, not a performance-tier decision.

Table note: both models share the same core sliding miter saw platform. Street-legend claims that the DWS782 has lower RPM, lower weight, or lower cross-cut capacity than the DWS780 are not supported by current spec references used for this refresh.
Why DWS780 Is Not a More Powerful Saw
The DWS782 and DWS780 share the same 15-amp / 3,800-RPM belt-drive motor, 12-inch sliding double-bevel frame, miter range, bevel range, crown/base capacity, 56-lb saw weight, and dust-port class. The single meaningful SKU-level difference is the factory-integrated XPS/CUTLINE LED shadow-line system, which ships standard on the DWS780 and is omitted from the DWS782.
XPS/CUTLINE works by casting a true shadow of the blade kerf onto the workpiece. That means it tracks actual blade thickness and does not need the alignment routine that bolt-on lasers often require. For the adjacent no-XPS vs XPS ladder, see our DeWalt DWS779 vs DWS780 sliding miter saw tier comparison.
Buy the DWS780 if you were already planning to add a bolt-on cutline aid, because factory XPS is cleaner than an aftermarket workaround. See our DWS716XPS vs DWS780 miter saw tier page if you are deciding between non-sliding XPS and sliding XPS.
Both DWS782 and DWS780 are 12-inch double-bevel sliding compound miter saws, not fixed-head chop saws. That sliding rail travel changes setup and clearance needs; our beginner miter saw guide covers core setup and safe-use habits.
Use-Case Winners: Which Model Fits Your Workflow
Before buying either saw, confirm your miter saw stand and jobsite setup can handle the weight, rear-slide clearance, and support needs of a 12-inch sliding saw.
| Workflow / Scenario | Clear Winner | Why |
|---|---|---|
| Trim, casing, and finish carpentry | DWS780 | XPS/CUTLINE speeds up accurate cut-to-mark alignment. |
| Rough framing, blocking, deck work | DWS782 | Same motor and sliding capacity for less money. |
| Crown molding | DWS780 | Shadow line helps compound-angle alignment and reduces bad cuts. |
| Budget under the DWS780 street price | DWS782 | Put the saved money toward blades, stand, PPE, or dust control. |
| Low-light shop or jobsite | DWS780 | The XPS LED doubles as cut-zone illumination. |
| Already buying an aftermarket laser | DWS780 | Factory XPS is cleaner and more accurate than bolt-on laser solutions. |
| Resale value | DWS780 | Used buyers often pay more for factory XPS/CUTLINE. |
| Same-capacity production cutting where marks are less critical | DWS782 | Identical frame, rails, motor, and cutting capacity. |

DWS782 vs DWS780 FAQs
What is the main difference between the DeWalt DWS782 and DWS780?
The main difference is XPS/CUTLINE. The DWS780 includes the factory LED shadow-line cut positioning system, while the DWS782 does not. Motor, rails, bevel range, miter range, cutting capacity, weight, and dust-port class are otherwise very similar.
Do the DWS782 and DWS780 have the same motor?
Yes. Both use a 15-amp motor with 3,800 RPM no-load speed. Dust collection is also the same class on both; if that is your concern, see our DWS716XPS vs DWS779 comparison for adjacent DeWalt miter saw workflow notes.
Does the DWS782 have XPS?
No. The DWS782 does not include factory XPS/CUTLINE. If a listing says otherwise, treat it as a likely catalog copy error and verify the exact SKU before buying.
Does the DWS780 have XPS?
Yes. The DWS780 includes DeWalt’s factory XPS/CUTLINE shadow-line system. That is the main reason to choose it over the DWS782.
Is the DWS780 worth the extra money?
Yes for trim carpenters, crown installers, cabinet work, and repeated precise cuts. It is less important for rough framing or occasional work. For broader miter saw choices, see our best miter saw for homeowner guide.
Which is better for crown molding?
The DWS780 is better because XPS/CUTLINE helps line up compound miter and bevel cuts more confidently. The DWS782 has the same mechanical crown capacity but lacks the factory cutline aid.
Which one should I buy?
Buy the DWS780 if cutline visibility, trim accuracy, and repeatable finish work matter. Buy the DWS782 if you want similar sliding capacity for less money and can live without XPS.
Original Comparison Notes, Preserved and Fact-Checked
DeWalt DWS780 and DWS782 are two miter saws with similar features, but there is one that is more suitable for your needs. (editor note Sep-2026: the 15-amp / 3,800-RPM motor, sliding frame, bevel, miter, cross-cut, fences, dust, and weight are identical across both suffixes; the single meaningful difference is the XPS/CUTLINE LED shadow line on the DWS780.) Compare speed, design, power, and accuracy between the miter saws. Let us have a look at how they compare.
DeWalt DWS782
The DEWALT DWS782 slide compound miter saw is for most cutting applications, including crown molding up to 7-1/2 inch It features a powerful 15 Amp, 3,800 RPM motor that delivers extended power and durability. The exclusive back fence design cuts to 2 x 16-dimensional lumber at 90 degrees and 2 x 12 at 45 degrees.
Due to its High-Visibility scale and easy angle adjustment, the dual bevel system is easy to see and use in job site conditions. Its bevel is from zero to 49 Degrees with positive stops at 0 Degrees, 22.5 Degrees, 33.9 Degrees, 45 Degrees, and 49 Degrees in both right and left directions.
The saw also miters 60 Degrees to the right and 50 Degrees to the left and features an adjustable miter detent plate with 10 Positive stops. A cam lock miter button allows the user to lock angles between detents. A miter detent override allows precise angle adjustment without falling into detents.
Pros
- Powerful

Features of the DeWalt DWS782
Power
This miter saw comes with a 15 amp motor power that aits the blade spin for up to 3,800 RPM. That means you may not cut through all different kinds of wood. You would also be able to have the needed convenience to make the power cord of the motor route the rail back of the machine. It does not have to interfere while the miter saw does its job.
Rails and fence system
It has dual horizontal steel rails, an innovative clamping mechanism and linear ball bearings for an accurate, durable, and compact saw. Tall sliding fences support crown molding up to 7-1/2 inch nested and base molding up to 6-3/4 inch vertically against the saw fence while easily sliding out of the way for bevel cuts.
Stops
An adjustable stainless steel miter detent plate with ten positive stops improves productivity and ensures cutting accuracy.
Miter system
Miters 60 degrees to the right and 50 degrees to the left, providing increased capacity. Precise miter system and machined base fence support optimize durability and cutting accuracy (Undersignmag.com). Its system has a dual bevel that makes easy angle adjustments and allows one to go from 0 to 49 degrees. It has positive stops at 49 degrees, 45 degrees, 33.9 degrees, and 22.5 degrees in both directions.
Design
The Compact, lightweight design is for easy transport and storage. The cam lock miter handle with detent override delivers quick and accurate miter angles. Unlike other saws, this miter saw has a compact dimension at 33 x 23.7 x 18.8 inches. This fits in any trailer or at the back of your truck.
Features of the DeWalt DWS780
XPS the shadow line cut indicator.
The DWS780 is sturdy and adjustable. It remains accurate without compromising speed during your use of the tool.
Bevel stop
It has a fast discharge bevel stop setting up to 49° left and right. The unique depth stop allows the saw to track falsework. The new quick-release bevel stop setting provides the accurate and simple setting of bevel angles up to 49° left and right.
It features the easy-to-use miter and bevel controls making the tool fast and simple to change from one setup to another. The Cam action miter lock function makes miter setting faster and easier, allowing the user to adjust angles between 0° – 50° left and 0° – 60° right.
Miter lock
It also features a cam action miter lock, making your miter setting quicker and more efficient. It allows the user to work with angles between 0° – 50° left and 0° – 60° right (Diyspotlight.com).
Speed control
Electronic speed control is for adjusting cutting speed when using non-ferrous materials. Clamps are for cutting non-ferrous materials.
Sliding fence
The large dual sliding fence gives maximum support in large, material cuts at any angle or combination of angles.
What could have been better?
DeWalt DWS782
- It may have other extra features, but it failed to provide a laser guide that would have made cutting a much easier.
- It could have been available in multiple colors.
DeWalt DWS780
- It could have been a bit lighter for easy movement.
- Ruler markings would have made it convenient to use.
Similarities
- Both have no laser.
- Both tools produce 3,800 rotations per minute.
Differences
- The DWS780 includes the XPS/CUTLINE cross-cut positioning system; the DWS782 is the lower-feature version without that factory cutline light. (editor note Sep-2026: prior copy reversed which model includes XPS/CUTLINE; manufacturer SKU pages, shared instruction manual, and regional distributor spec cards all confirm factory XPS/CUTLINE is standard on the DWS780 suffix only.)
The verdict
DeWalt miter saws are great tools that will improve any workshop. The difference between them is slight, but that separates the two. By now, you should have your best pick. A corded tool such as the DeWalt DWS780 gives you a continuous flow of electricity/power. If you need to transport your saw tool frequently, you may prefer the DWS782 if it costs less. (editor note Sep-2026: both saws share an identical 56-lb saw-only tool weight; there is no proven 4-lb weight difference between suffixes.) After all, it goes back to preference.
