DeWalt 20V Max XR Brushless Cordless Oscillating Multi-Tool Review

DeWalt 20V Max Brushless Oscillating Multi-Tool Makes Big Gains in PTR’s Ratings

We waited months in great anticipation of testing the DeWalt 20V Max XR Brushless Cordless Oscillating Multi-Tool for a couple of reasons. First, we knew it was an upgrade over the previous brushless model. Secondly, because so many of you let us know how much better it is!


  • Moves from one speed to three speeds
  • Comfortable handle design
  • Multiple grip options to engage the trigger
  • Fast and easy accessory changes
  • Depth guide included
  • Excellent value


  • Some accessories require the included universal adapter to use

As we started making our initial cuts, two things because clear. For starters, the tool seemed to be genuinely faster than the last brushless model and clearly a big upgrade from the initial brushed one. That was a little bit of a surprise considering the DeWalt DCS356 has the same 20,000 OPM speed and 3.2° arc as the 355.

We also noticed the vibration seemed to more controlled than before. DeWalt doesn’t tout a specific vibration dampening system, but it seemed to be improved to our hands.

To see how it compares to other cordless oscillating multi-tools, we put it on the PTR Test Track. Here’s what it includes:

  • Undercutting a door jamb for tile installation
  • Drywall cutout for an electrical box
  • Removing trim by popping five finish nails
  • 12 inches of grout removal
  • Sanding 6 inches of 2 x 4 pine

Along the way, we have to change accessories twice.

When the dust settled, DeWalt finished the track in 1 minute, 27 seconds. To put that in context, that’s in third place overall behind Fein’s Supercut cordless in first place (1:24) and the Flex 24V multi-tool in second (1:26).

It was the combination of accessory changes, design, and performance that earned DeWalt such a high placement. The clamp-style changes are really quick. It’s not quite as fast as Starlock, but it’s awfully close. The only downside is when your accessories don’t have a rear cutout and you need to use the included universal adapter to install them.

The physical design also helped. As we had to shift angles to cut from various directions, the shape, size, and weight were made it highly maneuverable.

We will be happy to hear your thoughts
