DEWALT 20V MAX XR Brushless Cordless 7-1/4 in. Circular Saw, Tool Only (DCS590B)

Across the reviewers we read, the DeWalt DCS590B is the full-size 7-1/4-inch option for 20V MAX owners who need more depth and power than a 6-1/2 saw provides. DeWalt markets it as their most powerful 20V MAX circular saw with up to 5,500 RPM and 368 cuts per charge, and Home Depot's verified-purchase summary reports "excellent performance with smooth and clean cuts, lightweight design, and good battery life."

r/Dewalt sentiment is genuinely split, which is worth surfacing. One owner says it "does great," ripping 3/4 plywood and white oak stair treads with a 60-tooth Diablo blade and an 8Ah pack, while another flatly calls it "underpowered," describing a "night/day difference" after using a friend's dual-battery Makita. The takeaway across threads is that this saw rewards high-output batteries; on small packs it can disappoint.

The cons are concrete: there's a community report of a unit that wouldn't run out of the box, recurring notes that it needs a large battery to hit its stride, and as a tool-only purchase the cost climbs once you add a high-amp-hour pack. There's no high-trust lab test in this candidate's signals, so the verdict leans on retailer and community evidence.
