DeWalt gets away from traditional multi-tool ergonomics and controls - a move that a number of users will welcome and others will need some time to get used to. 

Overall Score 7.9 (out of 10)

We recently spent a fair bit of time with 26 different oscillating multi-tools for our head to head shootout. Now, we’re taking some time to look at each of these tools individually. On today’s docket, we have the 20V Max DeWalt Cordless Oscillating Tool.

Noteworthy Features

Standard Pro Features

  • Brushless Motor: Brushless motors have slowly become the industry standard for Pro-level tools, so much so that we’ve found ourselves feeling let down when we find a new tool that still uses a brushed motor. Brushless motors provide more power and longer runtimes, as well as generally just lasting longer. Far be it from DeWalt to let us down in this department; their 20V Max multi-tool features the brushless motor that we’ve come to expect.


  • Lock On/Off Switch: Most oscillating multi-tools use a grinder-style on/off switch. Since the DeWalt Cordless Oscillating Tool uses a variable speed trigger, a lock on is crucial for those longer jobs. DeWalt is on board with that thinking and makes sure to include one.

  • LED Work Light: LED lights are much more common on cordless oscillating tools than corded, and lo and behold, DeWalt’s 20V Max model doesn’t let us down in this department.


Bonus Features

  • Dual-Grip Variable Speed Trigger: I prefer an on/off switch to DeWalt’s trigger format. But if you plan to go with a model that features a trigger design, we really like DeWalt’s. The dual-grip design helps with ergonomics and allows you to trigger the tool from multiple grip positions.

  • DeWalt Cordless Oscillating Tool Guide System: This optional feature, which comes with the kit, allows the user to set a consistent depth for repeatable accuracy.

Missing Features

  • Variable Speed Dial: An oscillating multi-tool that has an on/off switch needs to pair it with a variable speed dial to make it more versatile. DeWalt makes a trade-off (the positive is in ergonomics) with a variable speed trigger. It’s tough to maintain a consistent speed other than full speed with this design considering the kind of awkward cuts you’re often making. I like the physical design, but I’d like to see DeWalt add a variable speed dial to it so I can just pull the trigger instead of trying to feather it.


The DeWalt Cordless Oscillating Tool features the same thoughtfulness that the company puts into their other tools. The handle diameter is on the smaller side, and it has plenty of grippy overmolding. As I previously mentioned, this model features a trigger design that allows for multiple hold positions. Moving away from the traditional multi-tool styling, the handle ergonomics are up there with Ridgid as our Pro team’s favorite.

At 3.03 lbs with a slim pack battery, it doesn’t weigh a whole lot either.

Overall, the DeWalt Cordless Oscillating Tool finished in 3rd place with 4.5 stars for its ergonomics, bested only by the Ridgid models.

Accessory Changes

Though it doesn’t use the Starlock System that we like so much, DeWalt has a pretty solid system working for it. Basically, a squeeze of the silver trigger loosens the blade enough to pull it out from the clamps. No extra tools, no muss, no fuss. Outside of Starlock, it’s the easiest system to work with and earns 4.5 stars.

Vibration Control

Vibration is where we start to see the DeWalt Cordless Oscillating Tool lose a step or two. The vibration control on this model, or lack thereof, really hurts this tool’s final rating. After using this multi-tool for an extended amount of time, the chances are good that you’ll definitely know it – the vibrations rattling up your arm will likely cause some significant fatigue. Overall, it earns a 3-star rating for vibration control.

If you’re sticking mainly with making small cuts as your primary need for this tool, the vibration won’t be as big of a deal as extended sanding or grout scraping duties.

Noise Level

DeWalt has one of the loudest multi-tools we tested 102 dB(A) during the cut. For those of you keeping score, this means that the DeWalt Cordless Oscillating Tool finished in a tie for 10th place. Of course, a set of earplugs can remedy this problem. Realistically, you’re likely going to need them with any oscillating multi-tool. DeWalt earns a 3-star rating here, too.

Cutting Speed

While not the fastest-cutting multi-tool we tested, the DeWalt Cordless Oscillating Tool is no slouch either. At a top speed of 20,000 OPM and an oscillating angle of 1.6° (3.2° L/R combined), this tool hums right along. In our plunge cutting test, DeWalt’s 20V Max Oscillating Multi-Tool averages 18.1 seconds. That’s good enough for 10th place overall and a 4-star rating.

Price And Value

For the kit, this model will run just under $300. We came across a few cheaper kits than this, however many of those cheaper models might not meet our qualifications for Pro-level tools. The DeWalt Cordless Oscillating Tool Kit presents a solid 4-star value rating and finishes in 15th place for value.
