DeWalt Atomic Reciprocating Saw Vs Milwaukee M18 Fuel Hackzall Thursday Throwdown!

The DeWalt Atomic reciprocating saw didn’t make it in time for our compact cordless reciprocating saw head-to-head review. However, it’s here now and we’re putting it up against the best.

  • Tested Battery: Milwaukee M18 5.0Ah
  • Motor: Brushless
  • Stroke Length: 7/8″
  • Stroke Speed: 0 – 3000 SPM

Read our review here.


Just setting these two saws side-by-side, it’s clear that DeWalt has a more compact design. At 12.4″ long, it’s the smallest design in the 18V one-hand class. One the other hand, Milwaukee is more than an inch and a half longer at 14.0″

Verdict: DeWalt

DeWalt Atomic Reciprocating Saw Vs Milwaukee M18 Fuel Hackzall


Without batteries, DeWalt’s Atomic is significantly lighter—3.2 pounds vs 4.1 pounds. With the 5.0Ah batteries we tested, the gap grows a little bit. The Milwaukee M18 Fuel Hackzall’s 5.7-pounds full weight is more than a pound heavier than the DeWalt Atomic reciprocating saw at 4.6 pounds.

Verdict: DeWalt

Feature Set

When it comes to features, here’s what we look for:

Orbital ActionNoNo
Variable Speed DialNoNo
Tool-Free Adjustable ShoeNoNo
Pivoting ShoeYesYes

On the surface, these two saws are neck-and-neck with the features we expect to see on one-hand reciprocating saws. But DeWalt takes a turn and adds two features that no other saw we’ve tested has.

The first is a belt hook. Yep, a simple belt hook. The DeWalt Atomic reciprocating saw is light enough to justify having.

The other is a shoe design that has a claw for gripping material. You can hook it on 2x material, round stock, ladder rungs, and more. Whether you use it or the belt hook, we love that DeWalt took the extra steps to add both.

Verdict: DeWalt

Nail-Embedded Wood Cutting

Most one-hand reciprocating saws aren’t great at cutting wood, especially 2x. However, some are good enough at it to get electricians and plumbers out of the occasional pinch, so we test it as a baseline.

Using 2 x 10 pressure-treated pine with five 16D nails in it and adding 5 pounds of weight to each saw, DeWalt needs an average of 52.62 seconds to cut through. Milwaukee needs just 32.91 seconds.

That’s not a surprising result when you look at the spec sheet. We expect Milwaukee’s 3000 SPM and 7/8″ stroke length to easily outstrip DeWalt’s 2800 SPM and 5/8″ stroke length. What’s left to ponder is how it will affect cutting thin materials.

Verdict: Milwaukee

Metal Cutting

We used 3/4″ EMT to see kind of cutting speed you should expect in thin metal.

DeWalt Atomic Reciprocating Saw Vs Milwaukee M18 Fuel Hackzall

In this test, DeWalt posts an average cut speed of 6.04 seconds—the second slowest speed we tested. Milwaukee accomplished the same cut more than twice as fast, finishing with a 2.66-second average.

Verdict: Milwaukee

PVC Cutting

Switching over to 3″ PVC, the gap in cutting performance doesn’t change much. The DeWalt Atomic reciprocating saw needs 12.77 seconds to make the cut while Milwaukee’s M18 Fuel Hackzall does it in just 5.47 seconds on average.

Verdict: Milwaukee


For our vibration testing, we had our testing team score every saw in the class on a 1 – 4 scale. We cut wood, metal, and PVC, focusing on how good the vibration control is in each.

DeWalt Atomic Reciprocating Saw Vs Milwaukee M18 Fuel Hackzall

In our original head-to-head review, Milwaukee had the best vibration control in the class. However, our tests with the DeWalt Atomic push it ahead of Milwaukee as the new leader!

Once the results were in, DeWalt finished with a vibration control score of 100 with Milwaukee posting an excellent 94 points. We don’t think there a reason to be disappointed with either one in this test.

Verdict: DeWalt

Compatible Tools

When it comes to compatible tools, both of these brands go really deep. Considering these one-hand reciprocating saws do a lot of work for electricians and plumbers, we have to take that into consideration.

On the M18 battery platform, there are several trade-specific tools that DeWalt doesn’t have yet. In the end, it’s a difference that tips the scale clearly in Milwaukee’s favor.

Verdict: Milwaukee


The DeWalt Atomic reciprocating saw runs $149 as a bare tool and $269 as a kit with a 5.0Ah battery. Milwaukee sits at $159 as a bare tool and $269 for the 5.0Ah battery kit.

If you’re already on one of these platforms, DeWalt’s bare tool price wins the day. If you’re not, it’s a toss-up. To settle things, we put both saws under the microscope of our value algorithm to see if we can get some separation.

DeWalt came away with 77 points on our value scale—1 more than Milwaukee’s 76 points.

Buy DeWalt Buy Milwaukee

Verdict: DeWalt


DeWalt’s standard warranty is 3 years and includes a 1-year service agreement and a 90-day money-back return guarantee. Milwaukee gives you a 5-year warranty. We’ll take the extra 2 years.

Verdict: Milwaukee

DeWalt Atomic Reciprocating Saw Vs Milwaukee M18 Fuel Hackzall Final Verdict

Adding up the final scores, we end up with 5 – 5 tie. But it’s not really a tie when you look at the stark differences in design. DeWalt clearly went after the most compact design while Milwaukee targeted higher performance. Which one you decide on really boils down to where your priorities are between those two design philosophies.

Buy the DeWalt Atomic reciprocating saw if you’re looking for the smallest saw you can get with the best vibration control.

Buy the Milwaukee M18 Fuel Hackzall if you want top-tier cutting performance and deeper compatibility with trade-specific tools for electricians and plumbers.

Very good comparison. The Dewalt is smaller and lighter, as well as less expensive and it shows in the cutting. I’m would like to get the Dewalt myself as I already have a large reciprocating saw. Just to note, the Milwaukee M12 FUEL is comparable to this Atomic in specs.

Can we expect a similar thowdown with DeWalt’s new 12v DCS312 vs the M12 Fuel? Since it also did not come out in time for the full head-to-head review.


Good review! I suspect that the longer stroke combined with the higher RPMs significantly contributed to the higher vibration feel of the Milwaukee. It’s good that each company placed their focus in different areas to separate them somewhat. That extra length could pose a problem in tight spots but both are capable of working between standard 16″ on center framing so I’m not sure how often that extra 1-1/2″ is going to be an issue. I typically use the new 3.0Ah battery on mine so it’s likely about 5.4 lbs which to me seems quite comfortable. Either way you’re going… Read more »
