Key Difference: Power Source and Power Options

As you can see in the chart above, the main difference between the two DeWalt miter saws is their power source.

The DeWalt DHS790AT2 is a battery-operated power tool. It is part of DeWalt’s FLEXVOLT product line. Meaning, this tool makes use of a battery system called FLEXVOLT, which allows you to switch between two voltages when you change tools. In addition, the DHS790 also gives you the ability to choose between two power sources – cordless or corded.

The DeWalt DWS780, on the other hand, is a corded machine. That said, don’t expect to get a charger and battery packs.
