Which is better for cutting metal?

The Milwaukee cuts faster, with 3,000 SPM and a 1-1/4 in stroke. The DeWalt still handles metal well with a brushless motor and variable-speed trigger, and it is easier to control overhead because it weighs less.

Is the Milwaukee worth the extra $80?

Only if you cut hard material often or already own M18 batteries. For occasional wood and PVC cuts, the DeWalt at $108.99 does the job for less.

Which saw lasts longer?

Both use brushless motors built for pro use. The Milwaukee adds metal-reinforced battery rails and an anti-corrosion blade clamp, which help on rough jobsites. Battery life depends on which packs you already own.

Do either come with a battery?

No. Both are tool-only listings, so you need a battery and charger. The Milwaukee uses M18 packs and the DeWalt uses 20V MAX or FLEXVOLT packs.

Which is easier to use overhead?

The DeWalt. At 5.1 lb it is 1.7 lb lighter than the 6.8 lb Milwaukee, and its compact body fits tighter spaces.

Which has better ratings?

The Milwaukee rates 4.6 out of 5 from 131 ratings; the DeWalt rates 4.4 out of 5 from 136 ratings. The gap is small.
