How long does a 9.0Ah battery last in this saw?

Runtime depends on the material and cut depth. A 9.0Ah FlexVolt pack gives long runs in framing lumber, and two packs in the box cover most of a workday.

Does it come with a blade?

The listing lists batteries as included accessories. Confirm whether a blade and charger are in the box before ordering.

Can it cut 2x lumber at 45 degrees?

The 7-1/4 inch blade and bevel capacity handle common framing cuts. Maximum depth at 45 degrees is less than at 90, so check the depth for thick stock.

Is it compatible with other DeWalt 20V batteries?

It runs on 60V FlexVolt batteries. FlexVolt packs also work in 20V DeWalt tools, but 20V Max packs do not power this saw.

Is this saw worth it over a corded circular saw?

If you cut away from power often, the cordless freedom and two included batteries justify it. For shop use with an outlet nearby, a corded saw costs less.

Our take on the Dewalt DCS578X2 (2x9.0Ah)

The DeWalt DCS578X2 is a 60V Max cordless circular saw with a 7-1/4 inch blade, 5,800 rpm no-load speed and a bevel capacity for angled cuts. It ships with two 9.0Ah FlexVolt batteries, which is a lot of runtime for a saw this size. It suits framing and heavy cutting where a cord would get in the way. No current price was given for this listing, so check the live comparison before buying.
