Overview
On DeWalt's 20 volt battery platform, the DCS590B saw is rated at 5500 RPM with a stated cutting capacity around 4 inches, weighing 9.88 pounds in a metal build.
The B suffix DeWalt uses on many of its model numbers typically marks a bare tool sold without a battery or charger, worth checking before buying if you don't already own compatible batteries. The 160 watt motor power figure paired with a 5500 RPM speed points to a saw built for fast, light material cuts rather than heavy duty ripping. As with the rest of this batch, only a star rating and purchase count accompany the listing, with no review text to draw on.
- 20 volt battery powered
- 5500 RPM rated speed
- 9.88 pound weight
- About 4 inch cutting capacity
Who it's for
Suits someone already invested in DeWalt's 20 volt battery platform who wants a light cordless saw for cuts within its roughly 4 inch capacity. Not the right pick for anyone without compatible batteries already, given the B suffix commonly means bare tool.
Strengths and trade-offs

Performance notes
A 5500 RPM speed on the 20 volt battery platform is what drives the cut, and at 9.88 pounds the saw stays light enough for one handed use through a session. The roughly 4 inch capacity figure caps the material size it's built to handle.
