DeWalt 20V Max Brushless Oscillating Multi-Tool Earns Big Gains in PTR's Ratings
We waited months and were very much looking forward to testing the DeWalt 20V Max XR Brushless Cordless Oscillating Multi-Tool for several reasons. First off, we know this is an upgrade over the previous brushless model. Second, because so many of you let us know how good it is!
advantage
- Move from one speed to three speeds
- Comfortable handle design
- Multiple grip options to engage the trigger
- Quick and easy accessory replacement
- In-Depth Guide Included
- value for money
shortcoming
- Some accessories require the included universal adapter to work
When we started making the initial cuts, two things became clear. For starters, the tool seems to be really faster than the last brushless model, and is clearly a big upgrade over the original brushed model. This is a bit surprising considering the DeWalt DCS356 has the same 20,000 OPM speed and 3.2° arc as the 355.

We also noticed that the vibrations seemed more controlled than before. DeWalt doesn't tout a specific shock system, but it seems to have improved on our hands.
To see how it compares to other cordless vibrating multitools, we put it on the PTR test track. It includes the following:
- Undercut the door frame to install the tiles
- Drywall cutout for electrical box
- Remove the trim by popping off the five facing pegs
- 12 inches of grout removed
- sanded 6" 2 x 4 pine
Along the way, we have to change parts twice.
DeWalt DCS356 Performance Speed Results
After the dust settled, DeWalt completed the track in 1:27. All that said, third overall behind the Fein Supercut cordless in first (1:24) and the Flex 24V multitool in second (1:26).

It's the combination of fitting variation, design and performance that earns DeWalt such a high ranking. Fixture styles change very quickly. It's not as fast as Starlock, but pretty close. The only downside is that when your accessories don't have rear cutouts, you'll need to use the included universal adapter to mount them.
Physical design also helps. The shape, size and weight make it highly maneuverable since we have to change the angle to cut from all directions.
Then there's cutting and sanding speed. While other models have greater swing angles, DEWALT's brushless motors are able to maintain high speeds and work faster.
three speeds
One noticeable change from the 355 is that the DeWalt DCS356 has three speed settings instead of just one. There's a selector switch on the foot, rather than going the variable-speed dial route on the side.

lock, lock
Many cordless tools have a lock or lock switch, DeWalt actually combines the two. Push the switch from the left or right with the trigger down and it locks the trigger. Push it from either side with the trigger closed and it will lock it.
size and weight
The physical dimensions of this DeWalt cordless oscillating multitool are the same as previous models and the Atomic version. It measures 11.2 inches from front to back and weighs 2.3 pounds naked. With the 2.0Ah battery, the weight increases to a very manageable 3.0 lbs.

Quick Change Accessory Changes
As we mentioned before, DeWalt's replacement parts are pretty quick. The Quick-Change system uses a very strong spring to push the blade clamp and hold the attachment in place. You push it up with two fingers to reveal the interface and hold the blade in place, then release the clip to secure it.

It needs fittings cut out in the rear to work. If you have a fully enclosed one, DeWalt includes a universal adapter to make it work. However, you lose the speed and convenience of the system.
Additional features
- Brushless Motor
- Includes Depth Gauge (Great for undercutting door frames!)

the bottom line
We're well aware that the DeWalt 20V Max XR Oscillating Multi-Tool is one of the top models available. It's a solid design, solid performance, and a significant upgrade from the previous version. Most importantly, DeWalt's value proposition is excellent.
