The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the DEWALT DCS590B is the strongest cordless 7-1/4 pick in this candidate pool. protoolreviews.com, a high-trust source, lists impressive cutting power, a fast electronic brake, generous bevel capacity, excellent cut depth, and comfortable ergonomics among its pros. Medium-trust r/Dewalt threads back this up with real-world reports of ripping 3/4-inch plywood and white oak stair treads when paired with an 8Ah PowerPack and a 60-tooth Diablo blade.
What reviewers liked
- High-trust protoolreviews.com endorsement on power, brake, bevel, and ergonomics
- Real-world community reports of ripping hardwood treads and plywood on larger packs
- Brushless motor and full 7-1/4 inch blade match framing capability
- Strong Amazon rating (4.6) despite smaller review count
Where it falls short
- Home Depot verified reviewers report isolated blade-binding and gear durability issues
- Performance falls off noticeably on smaller 2Ah batteries per YouTube and r/Dewalt feedback
- Bare-tool price is high once a suitable 6Ah+ battery is factored in
- Lower review volume than older DEWALT cordless models — less long-term data
Across the reviewers we read, the DEWALT DCS590B is the strongest cordless 7-1/4 pick in this candidate pool. protoolreviews.com, a high-trust source, lists impressive cutting power, a fast electronic brake, generous bevel capacity, excellent cut depth, and comfortable ergonomics among its pros. Medium-trust r/Dewalt threads back this up with real-world reports of ripping 3/4-inch plywood and white oak stair treads when paired with an 8Ah PowerPack and a 60-tooth Diablo blade. Community discussion notes it sits between the older DCS573B and the FlexVolt 60V saws — adequate for most users without stepping up to the larger platform.
Reviewers do not agree unanimously. Verified-purchase reviewers on Home Depot flag isolated instances of blade binding and gear durability concerns, and one YouTube reviewer cited in the signals said they weren't blown away, particularly on smaller 2Ah batteries. r/Dewalt community sentiment is that the saw needs a meaningful battery (6Ah or larger) to deliver its rated performance — buyers running 2Ah packs should expect bog-down. With the right battery, the consensus is that it closes most of the gap to corded performance.

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.
Both are brushless, cordless both 20V max. The DCS573B is "flexvolt advantage" and is priced at $215.36 on Amazon and the DCS590B is $249 at Lowes, no battery ...
