The DEWALT ATOMIC 20V MAX* Circular Saw (DCS571B) is a compact 4-1/2-inch cordless saw built around a brushless motor. It can cut up to 369 linear feet of 3/4-inch OSB on a single DCB205 battery charge (battery sold separately). The removable auxiliary handle, on-board blade key storage, electronic blade brake, and built-in dust port make it a capable tool for both job site and home use.
Why Consider This Product?
The DEWALT ATOMIC 20V MAX* Circular Saw packs a brushless motor into a compact body that still delivers real cutting performance. On a single DCB205 battery charge, it cuts up to 369 linear feet of 3/4-inch OSB. That kind of runtime means fewer interruptions whether you’re framing a shed or breaking down sheet goods.
The removable auxiliary handle gives you a second grip point, which makes a noticeable difference when you’re guiding the saw through long cuts or working at awkward angles. The hang hook keeps the saw off your workbench and within easy reach, which matters when you’re moving around a job site or cramped garage.
Features and Benefits
High Performance Brushless Motor
A brushless motor runs more efficiently than a traditional brushed motor because it has no carbon brushes wearing down over time. The result is more power from the same battery, less heat buildup, and a longer tool lifespan. For a cordless saw in this size class, that efficiency matters.
Hassle-Free Blade Changes
The blade key stores directly on the saw, so you’re not digging through a toolbox every time you need to swap blades. Blade changes take seconds, and you get back to cutting faster. It’s a small detail that adds up over a full day of work.
Enhanced Safety Features
The electronic blade brake stops the blade within seconds of releasing the trigger, which reduces the risk of accidental contact after a cut. The 1-1/2-inch finger trigger lets you choke up on the handle for tighter control when you need it. Both features help you stay in control without slowing you down.
Versatile Bevel Cuts
The 4-1/2-inch blade cuts through 2x material at 90 degrees, handling standard framing lumber without issue. The bevel lever adjusts the saw to 45 degrees for angled cuts through 1x dimensional lumber. That range covers most cuts you’ll run into on a typical DIY or construction project.
Product Quality
DEWALT builds this saw to handle regular use on job sites and in workshops. The housing feels solid, the adjustment levers have a positive lock, and the fit and finish are consistent with what you’d expect from the ATOMIC line. This is not a saw that feels like it will fall apart after a season.
What It’s Used For
The Perfect Cutting Tool
This saw handles wood, sheet goods, and light-duty cuts in plastic. It excels at ripping plywood panels, crosscutting dimensional lumber, and trimming material in place where a larger saw would be unwieldy. The compact size is a genuine advantage in tight spots.
Ideal for Construction Projects
On a construction site, you often need a saw you can grab, make a quick cut, and move on. The DCS571B is light enough at 6.2 lbs to use one-handed when needed, and the brushless motor gives it enough power to work through framing lumber without bogging down.
The Go-To Tool for DIYers
If you’re building a deck, putting up shelving, or doing basic home repairs, this saw covers the cuts you’ll need most. The compact size makes it less intimidating than a full-size 7-1/4-inch saw, and the brushless motor means it won’t run out of steam on a longer project day.
A Reliable Tool for Renovations
Renovation work often means cutting in confined areas, trimming pieces to fit, or making cuts close to walls and floors. The compact footprint of this saw makes it easier to maneuver in those situations. The dust port helps keep the work area clear, which matters when you’re cutting indoors.

Tips and Tricks For Best Results
- Match the blade to your material. A wood blade on sheet metal or tile will ruin the blade fast and produce a rough cut.
- A dull blade makes the motor work harder and leaves ragged edges. Swap it out before it gets to that point.
- Wear safety glasses and cut-resistant gloves every time. Debris and kickback happen quickly.
- Let the saw reach full speed before entering the cut, and keep steady pressure throughout for a clean, accurate line.
- Read the manual for the recommended maintenance schedule. Keeping the blade guard clean and the battery contacts clear will extend the life of the saw.
