How deep can the DeWalt Atomic 4-1/2 in saw cut?

The 4-1/2 in blade limits it to roughly 1-1/2 in at 90 degrees, so it handles 1x and 2x trim but not deep framing cuts. Check the depth scale on the saw for the exact setting at 45 degrees.

Does it come with a battery?

This configuration includes a 20V Max 4.0 Ah battery. Confirm the listing shows the kit version if you need the charger too.

Will my other DeWalt 20V batteries work in it?

Yes. It uses DeWalt's 20V Max battery system, so packs from other 20V Max drills, drivers and saws fit.

Is it a replacement for a 7-1/4 in circular saw?

No. It is a compact companion saw for trim, siding and quick cuts. For full-depth framing cuts you still want a 7-1/4 in saw.

Can it cut plywood and 2x4s?

It cuts 2x4s and thinner plywood in one pass at 90 degrees. Thicker stock or deep bevels need a larger saw.

Our take on the Dewalt Atomic 20V Max 4-1/2 in Circular Saw

The DeWalt Atomic 20V Max is a compact 4-1/2 in cordless circular saw built for one-handed cuts and tight spaces. It runs on DeWalt's 20V Max batteries and ships with a 4.0 Ah pack, so it shares batteries with the rest of the 20V line. The small 4-1/2 in blade limits depth of cut, so it is a trim and framing companion rather than a replacement for a 7-1/4 in saw.

What reviewers say

Owners treat the Atomic as a handy second saw: light, easy to control one-handed and convenient on the DeWalt 20V battery platform. Most criticism centers on its shallow cut depth and its role as a companion rather than a primary saw.
