Our take on the DEWALT DCS391N Premium XR Circular Saw 165mm 18V Bare Unit

The DEWALT DCS391 is an 18V cordless circular saw that runs on DEWALT's XR slide-on batteries. It uses a fan-cooled motor with replaceable brushes and a cast magnesium base, and it takes 165mm blades with a 20mm bore. Cutting depth is 55mm at 90° and 42.1mm at 45°, which covers panel trimming and chipboard work rather than deep framing cuts. It suits tradespeople already on the 18V XR platform; the bare unit has no battery or charger, so the value depends on batteries you already own. Against compact 18V saws it is heavier at 3.8kg but has the metal base and brush access that cheaper models lack.

Questions and answers

Does the DCS391N include a battery and charger?
No. It is a bare unit, so you need an 18V XR slide-on battery and charger, or the kit version.
What size blade does it take?
A 165mm blade with a 20mm bore. A carbide blade, hex key and dust port come in the box.
How deep will it cut?
55mm at 90° and 42.1mm at 45°, enough for most sheet goods and thinner timber.
Is it worth it over a cheaper corded saw?
If you already own XR batteries, the cordless freedom and magnesium base justify it. Without batteries, a corded saw is simpler.
Can I use it for framing?
For light framing and trimming, yes. For repeated deep cuts in thick lumber, a larger saw with more depth is better.
Where is the DEWALT DCS391N Premium XR Circular Saw 165mm 18V Bare Unit cheapest?
At Walmart, for $338.95, as of our latest check.
