The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the DCS590B is the most consistently praised 7-1/4" cordless saw on DeWalt's 20V MAX platform. protoolreviews.com calls out impressive cutting power, a fast electronic brake, generous bevel capacity, and comfortable ergonomics, and notes that 2x pine studs put up little resistance even under load. Verified-purchase reviewers at homedepot.com echo the power and battery-life themes, and r/Dewalt threads describe ripping 3/4" plywood and white oak stair treads with a 60-tooth blade and an 8Ah pack without drama.
What reviewers liked
- High-trust expert review at protoolreviews.com cites strong cutting power and fast electronic brake
- Verified-purchase reviewers at homedepot.com consistently praise battery life and cordless convenience
- r/Dewalt users report ripping 3/4" plywood and hardwood stair treads with no bogging on larger packs
- 7-1/4" blade allows full-depth 2x cuts at 45° that 6-1/2" saws can't match
Where it falls short
- Reviewers note it's noticeably heavier than 6-1/2" sidewinders on the same platform
- Community threads agree runtime suffers badly on 2.0Ah batteries
- Sold as bare tool at this price; battery and charger are an additional spend
- DeWalt's own FlexVolt 60V saws are stronger if raw power is the priority

The honest caveats surface in the same community threads we read: it's a heavier saw than the 6-1/2" sidewinders, and runtime drops sharply if you pair it with a 2.0Ah battery instead of a 5.0Ah or FlexVolt pack. Reviewers comparing it to DeWalt's FlexVolt 60V saws agree the true 60V models edge it on raw power, but on the 20V MAX platform this is the well-rounded pick for someone who already owns DeWalt batteries and wants a do-everything cordless saw.

I have this saw. It does great. I have ripped 3/4 plywood and white oak stair treads. 60 tooth Diablo blade and 8ah powerpack keep it slappin.
It's powerful and sturdy and accurate, however the only downside is that it's relatively heavy. Never had a problem with it cutting super ...
