Overview
The DCS577B is DeWalt's 60 volt cordless saw, running a carbide-tipped blade at up to 5,800 RPM. Sold as a bare tool at 10.9 pounds, it targets tradespeople already on DeWalt's battery platform who need corded-level cutting power without a cord.
Bare tool listings like this assume you already own a compatible 60 volt FlexVolt battery and charger, since neither ships in the box. The 5,800 RPM motor speed and carbide blade point to a saw built for repeated cutting rather than fine finish work.

Who it's for
Suits contractors and serious DIYers already invested in DeWalt's 60 volt battery system who want to cut a cord on a job site saw. Not a fit for anyone starting from zero on batteries, since this listing is tool only.
Strengths and trade-offs
Drawn from this product's published specifications.
- Runs on DeWalt's higher-output 60 volt FlexVolt platform
- Carbide-tipped blade suited to repeated cutting
- Compact enough at 10.9 pounds for one-handed use
- Sold as bare tool, no battery or charger included
- Locks you into DeWalt's 60 volt battery ecosystem
Performance notes
The listed 5,800 RPM spindle speed and carbide-tipped blade are aimed at fast, repeated cuts rather than delicate trim work. At 60 volts the saw draws from DeWalt's higher-capacity FlexVolt line, which generally sustains power under load better than the standard 20V line, though runtime depends entirely on the battery you pair it with since none is included.
