DeWalt DCS573B Full-size 7-1/4-inch cordless saw that gets a power boost with 60V FLEXVOLT batteries. This page is a research-backed, spec-checked review page for readers who want the quick buying context behind the product card, not a recycled retailer description.

Who This Circular Saw Is For

DeWalt buyers who want a circular saw for sheet goods, dimensional lumber, deck repair, and jobsite cuts. The strongest case for this model is not just the badge on the side; it is whether the platform, size, and configuration match the work you repeat most often. For a buyer already invested in 20V / FLEXVOLT, DeWalt DCS573B can make more sense than starting over with another battery ecosystem.

It is also a practical choice when the job calls for sheet goods, dimensional lumber, deck repair, and jobsite cuts and you want one tool that stays inside a familiar brand platform.

Spec Check

We checked the product record for the model name, battery platform, bare-tool or kit positioning, and the outbound retailer link before keeping it live. The current record identifies this as the bare-tool configuration, which matters because batteries, chargers, blades, wheels, bars, chains, and cases can change the real checkout cost.

Blade platform and battery size matter as much as the model number because they change both cut depth and runtime. The model number, included accessories, and platform fit are the details most likely to decide whether this is the right buy.

What Stands Out

FLEXVOLT battery increases blade speed beyond standard 20V MAX output for denser material. 7-1/4-inch blade handles structural lumber beam cuts in a single cordless pass. Those are the reasons this model still belongs in the review database and related buying guides. The best use case is a buyer who understands the platform tradeoff and wants a tool that fits a specific workflow instead of a generic all-purpose recommendation.

Tradeoffs To Know

Bare tool only -- battery and charger sold separately. FLEXVOLT battery adds weight versus standard 20V MAX packs for the same tasks. Those limitations are not automatic dealbreakers, but they are the details that separate a smart purchase from a regret buy.

If you are comparing this against a kit, check whether the competing package includes the battery size you would actually use. If you are comparing it against another bare tool, compare the platform you already own first, then the headline specs second.

How To Compare It

The cleanest comparison set for DeWalt DCS573B is not every circular saw on the market. It is the closest same-platform model, the closest competing-brand model, and the cheapest credible alternative that still covers sheet goods, dimensional lumber, deck repair, and jobsite cuts. That keeps the decision grounded in real buying tradeoffs instead of spec-sheet noise.

For most readers, the first question is platform ownership. If you already own batteries in 20V / FLEXVOLT, this model gets a natural advantage because the checkout price can stay lower and the tool is easier to fold into your shop. If you do not own the platform, treat the battery and charger as part of the purchase even when the retailer headline makes the tool look inexpensive.

The second question is workload. A buyer doing occasional homeowner work can prioritize weight, control, and package value. A buyer using the tool every week should put more weight on durability signals, accessory availability, and whether the tool has enough headroom for tougher material. That difference is why this review keeps the recommendation tied to use case rather than calling it a universal winner.

Bottom Line

DeWalt DCS573B is worth considering when you want a DeWalt Circular Saw option and the 20V / FLEXVOLT platform fits your shop. It is not the automatic pick for every buyer, but it is a credible shortlist model when the configuration, accessories, and real work pattern line up.

Correction, October 21, 2026: Removed obsolete references to a numerical rating. This research-backed page does not present a measured test score.
