DeWalt DWS780 vs DWS779: what is the key difference?
The DWS780 is distinguished by its cut-line indication system. Decide whether that visual aid is useful for your work, then confirm it on the exact saw configuration you plan to buy.
A cut-line indicator can help you see where the blade will meet the workpiece. It doesn't replace setting the saw, supporting the material, or checking the cut before making it.
The DWS779 may suit you if you don't need that feature and its specifications meet your needs. Check the manuals for both exact models before assuming their other capabilities are identical.

Which saw should you choose for your projects?
Choose the DWS780 if its cut-line indicator is useful for your work; choose the DWS779 if you don't need that aid and its specifications fit. The right choice depends on the projects you plan to tackle.
For trim and molding, consider how often you make repeat cuts and how much setup time matters. A cut-line aid may help with alignment, but measuring and making a test cut still matter.
For framing or rough cuts, the indicator may matter less than capacity, mobility, and how the saw fits your workspace. Confirm the specifications for the material you regularly cut.
When does the DWS780 make more sense?
The DWS780 may suit you if seeing the intended cut line on the workpiece is a priority. That feature can help you understand where to position stock for a cut.
Check the manual for how to set up and maintain the cut-line system. Keep your hands clear and follow the saw's safety instructions even when the line looks clear.
When does the DWS779 make more sense?
The DWS779 may suit you if you don't need the DWS780's cut-line system and its capacity, adjustments, and footprint meet your needs. Compare the exact manuals before choosing.

What should you compare before buying?
Compare the exact specifications and package contents for both saws before choosing. A model name alone doesn't tell you whether a saw will fit your stock, bench, or available room.
Start with the cuts you need: crosscuts, miters, bevels, and compound cuts. Check the published capacity for the angles and material thickness you use, since capacity can change with the cut.
Next, measure the saw's footprint and the room needed for its sliding motion. A saw that fits on a bench while parked may need more room when its rails extend.
Verify whether the package includes the stand, blade, clamp, and other accessories you expect. Check the manual or exact package information for what comes with the saw.

What accessories fit both models?
Some replacement parts and inserts name both the DWS779 and DWS780 as compatible, but check the exact model and part before buying. Compatibility for one accessory doesn't mean every accessory fits both saws.
The DEWALT OEM N544383 kerf plate names both models as compatible. Check the part number and your saw's model before ordering.
Zero-clearance inserts also name both saws as compatible. The Generic insert can be customized for blade size, while the CNC Designs set includes 3 inserts calibrated for specific blade and bevel combinations.
The clamp assembly is compatible with the DWS780 Type 1, but DWS779 compatibility isn't specified. Check the saw type and fit if you need a clamp.
Use an insert according to its instructions. Each zero-clearance insert is calibrated to a specific blade and bevel angle, so it isn't suitable for every cut.
How do you set up either saw safely?
Follow the exact saw manual for assembly, adjustment, and operation. Support and secure the workpiece before cutting, and keep hands outside the blade path.
Place the saw on a stable surface or suitable stand. Check clearance for the sliding rails, fence, and long stock before making a cut.
Use eye and hearing protection, and connect dust collection if the saw supports it. Keep guards in place and hands away from the blade while it moves.
Review the guide to using a DeWalt miter saw before operating the saw. Read the manual for your exact model, since setup steps and safety details can differ.
Which DeWalt saw should you choose?
Pick the DWS780 if its cut-line indication is useful for your work; pick the DWS779 if you don't need that feature and its verified specifications suit your needs. Compare capacity, workspace needs, package contents, and exact model type before buying.
Start with your most common cut and measure the largest workpiece you need to handle. Then compare both manuals and choose the model that meets those requirements.
