Our take on the Dewalt ATOMIC 20V MAX Brushless 4-1/2" Cordless Circular Saw with POWERSTACK Battery
The DeWalt ATOMIC 20V MAX is a compact brushless 4-1/2-inch circular saw built for one-handed cuts and tight spaces. It runs on DeWalt's 20V MAX batteries and ships with a POWERSTACK pack, which is lighter and holds charge longer than the standard battery. The small blade limits it to trim, plywood and framing stock rather than full-depth dimensional lumber. It is a specialty saw, not a replacement for a 7-1/4-inch circular saw.
- Brushless motor for more runtime per charge
- Compact and light enough for one-handed use
- POWERSTACK battery is lighter than a standard 20V pack
- Bevel capacity for angled cuts
- Shares batteries with other DeWalt 20V MAX tools

What reviewers say
Owners treat it as a trim and sheet-goods saw and like the light weight and one-handed control. Most complaints center on the shallow cut depth and the small blade, which keep it from replacing a full-size saw.
- Cut depthCriticisedOwners say the 4-1/2-inch blade limits it to about 1-1/2 inches of cut, so it cannot handle 2x lumber.
- WeightPraisedBuyers like that it is light enough to use overhead and one-handed.
- BatteryPraisedThe included POWERSTACK pack is described as light and long-running for trim work.
Questions and answers
- How deep can the DeWalt ATOMIC 4-1/2-inch saw cut?
- At 90 degrees it cuts about 1-1/2 inches deep, enough for 1x stock, plywood and trim. It will not cut through a 2x4 in one pass.
- Does it come with a battery and charger?
- This configuration includes a 20V MAX POWERSTACK battery. Check the listing for whether a charger is bundled, since DeWalt sells several kit and bare-tool versions.
- Will the POWERSTACK battery work in my other DeWalt 20V tools?
- Yes. POWERSTACK packs use the same 20V MAX slide mount as other DeWalt 20V tools and chargers.
- Is this a good replacement for a 7-1/4-inch circular saw?
- No. It is a compact trim saw. Keep a full-size saw for framing and deep cuts and use this for sheet goods, trim and overhead work.
- What blade does it use?
- It takes a 4-1/2-inch blade with a 3/8-inch arbor. A fine-tooth blade gives cleaner cuts in plywood and trim.
