Overview
The DEWALT DCS577B runs on DEWALT's 60V MAX FLEXVOLT platform and spins its carbide-tipped blade at 5800 RPM, a blade speed comparable to many corded saws. Rated 4.6 stars across 1,300 verified reviews with roughly 100 units bought per month, it sits in proven demand territory for a premium cordless circular saw.
At 10.9 pounds the saw is on the heavier side for a cordless model, which is expected given the larger 60V battery pack. The listed cutting capacity is 4 inches, suited to dimensional lumber and engineered wood. The carbide blade material indicates a durable cutting edge that holds up to extended use.
Priced at $233.72 body-only, the DCS577B sits in the mid-premium cordless segment. Owners choosing it are typically investing in the FLEXVOLT platform for long-term tool compatibility rather than a standalone purchase.
