DeWalt DCS389X2 FlexVolt Reciprocating Saw Kit vs Milwaukee M18 FUEL SAWZALL 2821-22

Buy the DeWalt DCS389X2 if you cut heavy steel, cast iron or concrete forms and want corded-class power without a cord. Buy the Milwaukee 2821-22 if you want a lighter, more maneuverable saw for demolition, plumbing and everyday jobsite work. The DeWalt has the higher power figure and longer stroke; the Milwaukee has the longer track record with owners and a wear-resistant blade change. Both are brushless, both are pro-grade, and both are well rated.

  • Choose the DeWalt DCS389X2 if you need maximum cutting power and long runtime on heavy material, and you already own or plan to own FLEXVOLT batteries.
  • Choose the Milwaukee 2821-22 if you want a lighter saw with a proven blade change and you are already on the M18 platform.

What reviewers say

DeWalt DCS389X2 FlexVolt Reciprocating Saw Kit

  • 4.9 / 542 ratings

Rated 4.9 out of 5 across 42 ratings, buyers treat this saw as a corded replacement. They praise the power and the two-battery kit; the main gripes are weight and bulk.

What people mention
  • PowerPraisedOwners say it cuts through lumber and steel like a corded saw.
  • Battery runtimePraisedThe two 9.0Ah FLEXVOLT packs keep the saw running through long jobs.
  • WeightCriticisedBuyers find the saw heavy, particularly with a 9.0Ah battery attached.
  • SizeMixedThe large body limits access in tight spots, though it helps stability on big cuts.

Milwaukee M18 FUEL SAWZALL 2821-22

  • 4.8 / 5139 ratings

Owners rate the 2821-22 highly and describe it as a powerful, fast-cutting saw that holds up to daily jobsite use. Most praise the brushless motor, runtime and blade changes. The main complaints are weight and bulk.

What people mention
  • PowerPraisedOwners say it cuts through pipe, conduit and nail-embedded lumber without bogging down.
  • Battery runtimePraisedTwo 5.0Ah packs are reported to last through long work sessions, with one charging while the other runs.

Questions and answers

Which is better for cutting steel pipe?
The DeWalt has more raw power and a higher stroke rate, so it cuts heavy steel pipe faster. The Milwaukee still handles pipe well and is easier to control in tight spots.
Which lasts longer?
Both are brushless and built for pro use. The Milwaukee's wear-resistant blade change and anti-corrosion clamp are aimed at long service life, and its larger owner base backs its durability. The DeWalt's main long-life advantage is the bigger batteries, which mean fewer charge cycles.
Is the DeWalt worth stepping up to from an 18V saw?
Yes if you regularly cut cast iron, concrete forms or thick steel. For framing, PVC and light demolition, an 18V saw like the Milwaukee is enough and weighs less.
Which is easier to use overhead?
The Milwaukee. The DeWalt kit weighs about 18.9 lbs with a battery, which tires you faster when cutting above your head.
Do the batteries work in other tools?
Yes. DeWalt FLEXVOLT batteries run in 20V MAX tools, and Milwaukee M18 batteries run across the M18 line. Pick the platform you already own.
Which has the better blade change?
The Milwaukee's wear-resistant blade change is the more refined design and holds up to repeated swaps. The DeWalt uses a 4-position keyless lever clamp that is quick and lets you index the blade.
