Detailed Review
The DEWALT ATOMIC 20V MAX Circular Saw (DCS571B) is a compact cordless cutting tool built for quick cuts in tight spots and sheet goods. Operating on DEWALT's 20V battery platform, this tool-only model uses a 4-1/2-inch blade size to deliver portable cutting performance without the bulk of a full-sized framing saw.
Its brushless motor is engineered for solid efficiency, capable of cutting up to 369 linear feet of 3/4-inch OSB when paired with a DCB205 battery. Despite its small blade, a specially designed bevel gear allows it to cut through 2x material at 90 degrees. For angled cuts, the bevel lever tilts up to 45 degrees to slice through 1x dimensional lumber.
Usability features focus on handling and convenience. A 1-1/2-inch finger trigger lets you choke up on the grip for detailed work, while a removable auxiliary handle offers two-handed stability when needed. Safety and site cleanliness are supported by a fast-acting electronic blade brake, an on-board dust port, a built-in hang hook, and dedicated storage for the blade change key.
As a bare tool, you must supply your own 20V battery and charger to get started. While it handles 2x dimensional lumber at 90 degrees, beveling at 45 degrees is limited to 1x material due to the compact 4-1/2-inch blade diameter.
Verdict: This compact saw is a great pick for woodworkers and DIYers who want a lightweight, manageable tool for sheet goods and light framing. It offers strong cutting capacity in a trim form factor if you already own compatible DEWALT 20V batteries.

Consider something else if you:
- Need an all-in-one kit that includes a battery and charger right out of the box
