Features of the Dhs790

Miter scale

Accuracy comes through easy-to-read, bevel, and miter scales engineered with convenience and durability. The miter controls are upfront, and there is a detent override that you need to press and hold as you adjust with a standard lock for uncommon angles. DeWalt features a button that holds the detent override for you.

Blade

The Dewalt DHS790 has an adjustment-free cutline blade positioning system for improved accuracy. The DeWalt miter saw has its Cutline Blade Positioning System that uses a shadow to show you where the blade will contact your workpiece.

Power

It features a battery platform that can switch between 20V and 60V performance based on the tool’s requirements. It can run on either batteries or AC power. To get to 120 volts, DeWalt needs two FlexVolt battery packs installed behind the motor head. If you are working near a power source, you can swap them out for the 120V AC adapter packed in two of the kit options.

Bevel adjustments

The bevel lock can be on the back like other DeWalt miter saws. Once loosened, you can bevel left from 0 – 45 degrees. To override the stop at 0 degrees and bevel right, engage that on the back. DeWalt added bevel stops that pivot in our out-of-position for 22.5 and 33.86 degrees.

The movements are smooth. The only drawback is that the controls are on the back, forcing you to reach around the saw or move to the back to make adjustments.

Stock blade

DeWalt includes a 60-tooth, 12-inch blade. The new accessories make cordless tools. Chances are low that you will have cut speed or quality issues using the included saw blade. There are blades out there you might upgrade to the stock blade’s useful life is over, but the results are of high enough quality to warrant.

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.

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?

Dhs790

  • Controls could have been at the front.
  • It could have been lighter. 

Dewalt dws780

  • It could have been a bit lighter for easy movement.
  • Ruler markings would have made it convenient to use. 

Similarities 

  • Both saw tools are heavy.
  • Both cut large materials.
  • Both miter saws come with a powerful 15-AMP brushless motor. 
  • They are both reliable.

Differences

  • The DeWalt DHS790 is a battery-operated power tool, whereas the DeWalt DWS780 is a corded machine.

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 hate cords, the DeWalt DHS790AT2 might be for you. After all, it goes back to preference.
