Overview
The DEWALT DCS578B brings 60V FLEXVOLT power to a full-size 7.25-inch circular saw, delivering 5,800 RPM and 1,700 watts of motor output. At $188 for the tool only, it is priced aggressively for a saw with these specs, though buyers need a compatible FLEXVOLT battery to use it. The 8.2-pound figure is the bare-tool weight before the battery is attached.
Demand is strong: 1,400 reviews at 4.7 stars and 500 units bought last month put this among the top circular saws by recent sales volume in this dataset. That combination of high review count and strong monthly purchase rate confirms it is a mainstream professional saw, not a niche listing.
The 7.25-inch capacity and 5,800 RPM spec it for framing, decking, and full-depth lumber cuts, making it a direct competitor to corded worm-drive and sidewinder saws in that use case. The high speed steel blade is included.
Pros
- 7.25-inch blade capacity for full framing, ripping, and decking tasks
- 5,800 RPM and 1,700-watt motor output for high cutting speed and torque
- 4.7 stars from 1,400 reviews with 500 bought last month, strong demand signal
- $188 tool-only is a competitive price for a 60V full-size cordless saw
- High speed steel blade included
Cons
- Tool-only listing; FLEXVOLT 60V battery costs extra and adds significant weight
- 8.2 pounds bare tool is heavy relative to compact 20V saws
- FLEXVOLT battery platform requires higher investment than standard 20V MAX batteries

Performance notes
The DCS578B runs on 60V FLEXVOLT battery power and spins at 5,800 RPM with 1,700 watts of motor output. Its 7.25-inch capacity handles full-depth cuts in standard framing lumber. At 8.2 pounds for the bare tool, total weight increases substantially once a FLEXVOLT battery is installed. High speed steel blade material is noted in the specs.
What buyers say
Owners praise the DCS578B for cutting power that rivals corded saws and for its seamless fit into the FLEXVOLT battery ecosystem. The most frequent critique is that the overall weight with battery attached makes extended overhead cuts tiring. At 500 units sold last month it consistently draws buyers who view it as a professional-grade cordless solution.
