Our Take

Best for: Framers and carpenters who own DEWALT 20V tools.

The DEWALT DCS590B is a powerhouse among cordless circular saws. Its brushless motor churns out up to 1,700 MWO, making it DEWALT's most powerful 20V MAX offering. The 5,500 RPM no-load speed lets you rip through framing lumber and plywood with ease. The electric brake stops the blade in seconds, adding safety and precision. On the downside, this is a tool-only purchase, so you'll need a 20V MAX battery and charger. The right-side blade orientation may not suit left-handed users. At 25% off, this is a solid buy for pros who already own DEWALT 20V tools.

Price Analysis

At $187.99, this saw is 25% off the $249 list price. While price history isn't provided, that's a typical discount for a bare tool. It's a good time to buy if you're already in the DEWALT ecosystem.
