Overview
DeWalt's DCS571B is a 20V battery-powered saw built around a high speed steel blade and a roughly 2-inch cutting capacity, weighing 6.6 pounds. The B suffix on DeWalt models typically marks a bare tool sold without battery or charger.
At 6.6 pounds and 20V, this sits in DeWalt's compact cordless saw range built for one-handed cuts rather than deep rip cuts through thick lumber. The 2-inch capacity and high speed steel blade point toward a compact circular saw meant for trim, plywood and similar material rather than framing lumber.
- 20V battery powered
- About 2 inch cutting capacity
- 6.6 pounds
- Compact saw design
Who it's for
DeWalt 20V users who already own batteries and a charger and want a compact saw to add to the platform. Not the right buy for someone who needs a complete kit with battery included, since the B suffix points to a bare tool.
Pros and cons
- 20V battery platform, compatible with existing DeWalt batteries
- Light at 6.6 pounds for one-handed cuts
- High speed steel blade
- Cutting capacity limited to about 2 inches
- Bare tool, battery and charger likely not included
Performance notes
A high speed steel blade holds an edge through repeated cuts in wood and similar material, and the 2-inch capacity places this in compact saw territory rather than full-size circular saws that cut through thicker dimensional lumber. At 6.6 pounds, it is light enough for one-handed or overhead cuts, which is typical of DeWalt's compact 20V saw line.
