120V Max Sliding Miter Saw – Why It’s Making Waves Across The World

  • It provides you with the ultimate flexibility by giving you the option to run your miter saw on AC power or battery power
  • With a powerful 120V brushless motor, you get much longer run time when compared to brushed motors
  • With the integrated adjustment-free Cutline Blade Positioning System, this saw is extremely accurate and provides perfect working visibility
  • Thanks to the high visibility bevel scale, angle adjustments are always accurate and easy
  • The saw comes with tall sliding fences which will support crown molding up to 7/12 inches nested as well as base moldings up to 6-3/4 inches vertically
  • With its adjustable stainless steel miter detent plate, the capacity of this saw is greatly increased with the help of 11 detents, 60 degrees to the right and 50 degrees to the left

Notable Features of the DeWalt DHS790AT2 Double Bevel Compound Sliding Miter Saw Kit

Various Power Sources

Thanks to the FlexVolt 120V Max Sliding Miter Saw’s ability to run on AC power as well as battery power, it’s a hybrid tool.

This means that you’d easily be able to take some of the weight off the tool (yes, this monster requires two heavy FlexVolt batteries to operate) and just plug it into AC power if you’re working near a power source.

Blade Position Indicator

DeWalt’s Cutline Blade Positioning System relies on a shadow to indicate where and how the blade of this 12-inch, dual bevel, sliding miter saw will contact your workpiece.

We love the addition of the blade position indicator since it’s a super useful feature, one that is setting the pace for all of DeWalt’s competitors.

Miter and Bevel Adjustments

The miter and bevel adjustments on a miter saw (any saw for that matter) are, as you might know, kind of a big deal.

With the DeWalt 120V Max Sliding Miter Saw, the controls for the miter adjustments can be found up front, as can be expected.

A standard lock from uncommon angles is present along with a detent override that needs to be pressed and held throughout adjustments.

Luckily you won’t have to hold down the detent override since DeWalt added a handy button to do that for you.

Some users have commented on the fact that this saw is a little harder to pivot for miter cuts, and it’s a little stiffer when compared to its competitors, but that’s something that might require some easing in to.

Another key feature that we liked was the fact that this saw is able to move fast enough to effortlessly skip over notches without engaging the detent.

Adjusting the bevel is easy and the lock for the adjustment can be found on the back of the saw, just like all of DeWalt’s other miter saws.

When loosened, the bevel can be adjusted left from 0-45 degrees. You can override the stop at 0 degrees and bevel to the right, but to get that done, you’ll need to engage that adjustment on the back too.

To make the task easier, DeWalt included bevel stops which pivot out or in to position for 22.5 and 33.86 degrees.

Stock Blade

The DeWalt 120V FlexVolt Sliding Miter Saw comes with a 60-tooth, 12-inch blade. There haven’t been any significant issues reported with the stock blade that comes with this miter saw.

The options for upgrading your blade are endless, and once the stock blade’s lifespan has come to an end, you shouldn’t have any issues replacing it.

Notes on the Drive System

As you might be aware of, most miter saws use belt drive systems, and when it comes to the DHS790, it’s no exception to the rule.

This saw comes fitted with a Jason Industrial 220J, and with the addition of the ribbing, it may help delay stretching as long as possible. One of the best aspects of the drive system is the fact that the belt drive connects to a second gear drive.

What this does is to create a 90-degree angle to the arbor along with additional cutting height clearance, which is ideal for thin vertical cuts and crowning.

Cuts per Charge

You’d expect the DeWalt FlexVolt 120V MAX Sliding Miter saw to at least give you a fair amount of power and cuts per charge, and you’d be absolutely right with that expectation.

When fitted with the two 60V MAX FlexVolt batteries, the DeWalt Sliding Miter Saw is able to deliver at least 289 cuts on a 3-1/4 inch base molding per charge, which pretty much equates to enough power to last you an entire day.


Some sliding miter saws are simply impossible to move around from one space to another, but the DeWalt DHS790AT2 is an exception to the general rule.

Sure, it’s not a lightweight tool, but since it only weighs in at 56 pounds, it’s easy to carry this saw with you wherever you need to go.

  • Comes with a standard vertical clamp

How well does the DeWalt DHS790AT2 perform?

The DHS790 miter saw will have to be calibrated before the accuracy can be properly evaluated, and many users that have calibrated the saw have reported great accuracy with the saw.

As far as cutting power goes, it has been reported that this miter saw from DeWalt, when plugged into the AC adapter, has a motor rated for 15 amps, performing like even the most professional of corded miter saws.

What’s good to know is the fact that the DHS790 FlexVolt 120V Max Sliding Miter Saw cuts equally as good on battery power as it does when supported by AC power.

Something you might want to keep in mind with regards to this saw from DeWalt is its dust collecting abilities.

It’s more than a little rough, and users have reported that they ended up with a lot of leftover sawdust lying around after cutting.

Perhaps a dust extractor might do the trick here, but as far as its dust-collecting abilities go, the DHS790 comes in below average when compared to its competitors.
