Pick the DeWalt 20V MAX 7-1/4 in. circular saw (DCS570B) if...
You already have 20V MAX batteries, cut mostly plywood and framing lumber, and want to keep tool weight and cost down.
Pick the DeWalt FLEXVOLT 60V MAX 7-1/4 in. circular saw (DCS578B) if...
You cut thick or wet lumber, make long rip cuts, or want a cordless saw that stays closer to corded power on heavy jobs.
Who should skip both
You only make a few cuts a month. A corded circular saw costs less and never runs out of battery, or use a track saw if you need cleaner sheet-goods cuts.
Where to buy
Frequently asked questions
Is a 60V saw more powerful than a 20V saw?
FLEXVOLT 60V tools deliver more power for heavy cuts. DeWalt lists the DCS578B with up to 47 percent more power than its DCS575 saw; compare with the 20V saw for your own material.
Can I use 20V batteries in the FLEXVOLT saw?
FLEXVOLT batteries are designed to work across 20V MAX and 60V MAX tools, but a 60V tool on a 20V pack will have reduced power and runtime. Confirm compatibility on DeWalt.
Are these saws sold with batteries?
The listings here are tool only. DeWalt sells FLEXVOLT kits with batteries separately, such as the DCS578X1 and DCS578X2.
Which is better for a small shop?
The 20V MAX saw is usually enough for a home shop. Step up to 60V when you notice the saw slowing in thick or dense stock.
