Overview
The DEWALT DCS520B is a 60V FlexVolt cordless circular saw with a 6.5 inch cutting capacity and a 4000 RPM motor. At 12.5 pounds, the B in its model number marks it as a bare tool sold without battery or charger.
DEWALT's FlexVolt line runs on 60V batteries that automatically adjust voltage for compatible tools, and the DCS520B brings that platform into a circular saw sized for framing and general carpentry cuts. Bought past month reads 0 on this listing, so recent demand is quiet even against a strong 4.7 average across 374 ratings.
- 60V FlexVolt battery power

- 12.5 pound bare tool weight
Who it's for
Tradespeople and serious DIYers already on DEWALT's FlexVolt battery system who want a cordless saw with corded level cutting capacity. Not the pick for anyone who needs a battery and charger in the box, since bare tool listings require those separately.
Strengths and trade-offs
Drawn from this product's published specifications.
- 6.5 inch cutting capacity handles standard framing lumber
- 60V FlexVolt platform shares batteries with other DEWALT tools
- 4.7 average across 374 ratings
- Bare tool, no battery or charger included
- At 12.5 pounds it is heavier than smaller cordless circular saws
- Zero units bought in the past month on this listing
Performance notes
A 4000 RPM motor paired with 60V FlexVolt power is built to push through dimensional lumber without a cord, and the 6.5 inch capacity clears standard 2x material at square and beveled cuts alike. At 12.5 pounds the saw sits on the heavier side of cordless circular saws, trading some maneuverability for cut capacity.
