A 7-1/4 inch blade with 2-9/16 inches of depth at 90 degrees is the standard full-size circular saw capacity, and it cuts through a 2x4 in one pass and a doubled 2x in two. The brushless motor spins at 5,500 RPM with no load, and the listing quotes up to 1,700 MWO, DEWALT's measure of power at the blade. That is a corded-class figure, and it explains why this saw lasts longer per charge than a brushed model.
The tradeoff is the bare tool listing. You get the saw and nothing else, so you need 20V MAX batteries, and a 5.0 Ah pack or larger is the right match for sustained framing cuts. Versus the older DCS391B, the XR model is the stronger and more efficient saw. Versus the RYOBI ONE+ HP, the DEWALT adds a more established platform at a higher price.
Ownership: the platform is the long-term value. Keep the blade sharp, because a dull blade drains a pack twice as fast as a sharp one. Clean sawdust from the shoe and guard pivot, check that the lower guard snaps back quickly, and store packs half charged. Many framers keep two packs on rotation, one in the saw and one on the charger, which turns a bare tool into a full-day setup.
What works
- Brushless motor reaches 5,500 RPM and extends runtime
- 2-9/16 inch depth cuts a 2x4 in one pass
- Mature 20V MAX platform has tools for every job
- Quoted 1,700 MWO suits framing loads
Watch out for
- Tool only, so batteries and a charger cost extra
- Heavier with a large battery than 6-1/2 inch saws
- Highest relative price among the 20V MAX picks
