DeWalt ATOMIC 4-1/2 in. Circular Saw (DCS571B)

A true compact cordless saw: 4-1/2 inch brushless, and it still cuts 2x stock.

Our verdict

The DCS571B is the compact saw the category kept promising: genuinely small at about 5.5 lb, brushless, and with a bevel-gear layout that still severs 2x stock at 90 degrees. Trim, flooring, and plywood breakdown are its home; production framing is not, and it does not pretend otherwise.

What we like

  • Brushless 20V MAX motor spins the 4-1/2 inch blade at 4,500 RPM
  • Bevel-gear design cuts 2x material at 90 degrees and 1x at 45 degrees
  • Electronic blade brake stops the blade fast between cuts
  • Removable auxiliary handle and on-board dust port for controlled trim work

What to watch out for

  • 1-9/16 inch depth ceiling rules out doubled-up lumber and thick beams
  • Tool-only listing; battery and charger are separate if you are new to 20V MAX
  • Small blade selection is narrower than the 7-1/4 inch ecosystem

What owners report: DeWalt ATOMIC 4-1/2 in. Circular Saw (DCS571B)

Synthesized from recurring themes in long-term owner feedback.

Most praised

  • Bevel gearing that still cuts standard lumber depth in a compact body surprises owners expecting a toy
  • The electronic brake and auxiliary handle give trim work controlled, deliberate handling
  • An on-board dust port helps keep the cut line visible on finish work indoors

Common complaints

  • Depth ceiling rules out doubled lumber and thick beams entirely
  • Blade choice in this size is narrower than the full-size ecosystem owners are used to
  • Tool-only pricing assumes an existing battery collection

Who it is for

Remodelers, flooring installers, and DIYers who cut sheet goods and trim more than framing lumber.

Compact without the toy-saw compromise

Most 4-1/2 inch saws stall at panel stock. The DCS571B's bevel-gear design reaches 1-9/16 inches at 90 degrees, enough for a full 2x in one pass, and 1x at 45, which moves it from novelty to the saw that actually rides in the truck.

Control details

An electronic brake halts the blade quickly, a removable auxiliary handle gives a second grip for plunge and overhead starts, and the on-board dust port keeps the cut line visible in MDF and laminate, the materials this saw will meet most.

Runtime expectations

DeWalt cites up to 369 linear feet of 3/4 inch OSB per charge with a 5Ah battery in its materials, a manufacturer figure to treat as a ceiling. Real trim work, short cuts with pauses, is exactly the duty cycle where a compact brushless saw shines.

Questions, answered

Can the DCS571B cut a 2x4?

Yes. Its 1-9/16 inch depth at 90 degrees clears dimensional 2x lumber in one pass, and it handles 1x stock at a 45-degree bevel.

Does it come with a battery?

No. The DCS571B listing is tool only, so it suits existing 20V MAX owners; new buyers should price in a battery and charger.
