DeWalt DWS779 review: large capacity without the XPS premium
The DWS779 is a full-size 12-inch sliding miter saw for buyers who value crosscut capacity and dual-bevel flexibility more than a built-in shadow-line indicator.
How this guide has been updated
- Published with current manufacturer specifications, fit analysis, alternatives and source checks.
High-capacity general work, deck components, wide shelving, baseboard and crown where a corded 12-inch slider can remain on a stable stand.
Frequent carrying, very small benches, or buyers who want a factory shadow-line cut indicator.

What can the DWS779 cut?
DeWalt specifies capacity for 2x14 dimensional lumber at 90 degrees, plus tall-fence support for 6-3/4-inch base and 7-1/2-inch nested crown. Those figures make it useful when a compact non-slider would require a different cutting method.
Capacity at square does not transfer automatically to every bevel and miter combination. Check the manual’s capacity table for the exact compound angle and keep long material level with the saw table.
How should you think about accuracy?
The stainless-steel miter detent plate provides ten positive stops for repeatable common angles. That helps only after the fence, table and blade relationship have been checked according to the manual.
Unlike the DWS780, the DWS779 is not the choice for someone specifically buying DeWalt’s XPS blade-shadow system. Use a controlled test cut in scrap and preserve the waste side of the pencil line.
Does it fit a small workshop?
At roughly 56 pounds with rear slide travel, this is better treated as a station saw than a carry-everywhere tool. Measure total rear clearance, not just the base, and include hose, handle and bevel travel.
A suitable stand and level extensions matter as much as the saw when cutting long deck boards, baseboard or shelving. Unsupported stock can change the cut and create a handling hazard.
Should you buy the DeWalt DWS779?
Buy it when wide crosscuts, dual bevel and a mature corded platform matter more than portability or an integrated shadow line. For a small trim-only workload, a lighter 10-inch saw can be easier to store and move.
This conclusion is based on current manufacturer documentation and cited external context, not an undisclosed hands-on test. Confirm the exact model, included blade and current package before ordering.
Reasons to buy

- Dual-bevel and broad miter range
- Tall-fence capacity for base and nested crown
Reasons to pause
- Heavy for frequent transport
- Rear slide needs working depth
- No factory XPS shadow-line system

Is the DeWalt DWS779 good for beginners?
It can be, but its size, weight and capacity are more than many first-time trim projects require. A stable stand, manual-led setup and suitable work support are essential.
What is the main difference between the DWS779 and DWS780?
The most visible buying distinction is that the DWS780 includes DeWalt’s XPS cut-line system, while the DWS779 is commonly chosen to retain similar full-size capacity without that feature.
