DEWALT Circular Saw Review: Picking the Right Model, Battery and Kit
[AFFILIATE DISCLOSURE ] As an Amazon Associate, I earn from qualifying purchases.
Shopping for a DEWALT circular saw gets confusing fast. The brand sells compact 20V saws, full-size 20V saws, 60V FLEXVOLT saws and corded models. Many come as a bare tool or as a kit.
Pick the wrong one and you could end up with a saw that’s too small for your cuts. You could also open a box with no battery inside. Our research found that no single DEWALT saw suits every buyer.
The right choice depends on three things: whether you already own DEWALT batteries, how deep you need to cut, and how often you rip long boards. This review compares the main options and shows what a working setup really costs.
Which DEWALT circular saw does this review cover?
This is a brand-level buying review, not a test of one saw. The product link we received couldn’t be traced to a specific model, seller or package. Instead, we compare the DEWALT saws that independent reviewers have covered recently.
We haven’t used any of these saws ourselves. Specifications come from DEWALT’s own documents, and performance notes are credited to the reviewers who ran the tests.

How the main DEWALT circular saws compare on power, size and price
| Model | Power source | Blade size | Suited to | Price seen Nov. 2, 2026 |
|---|---|---|---|---|
| DCS391B | 20V cordless | 6-1/2 inch | Lighter cuts and occasional projects | $129 on product page; $99 shown on category page |
| DCS590B | 20V MAX cordless, brushless | 7-1/4 inch | Full-size cut depth on the 20V platform | $229, bare tool |
| DCS578B | 60V MAX FLEXVOLT, brushless | 7-1/4 inch | Demanding, heavier cutting | Not verified |
| DWE575SB | Corded | Not confirmed in our research | Work near an outlet | Not verified |
Both observed prices came from Northern Tool and cover the saw alone. They’re retailer snapshots, not list prices. The two DCS391B figures conflict, so treat the lower one as unconfirmed until you see it at checkout.

What DEWALT saws can cut: spec sheets versus real tests
DEWALT’s published numbers for the DCS590
The DCS590 has the clearest manufacturer documentation of the group. DEWALT’s spec sheet lists:
- Brushless 20V MAX motor running at 5,500 RPM
- 7-1/4-inch blade in a blade-right layout
- Electronic brake to stop the blade quickly after you release the trigger
- 57-degree bevel range, with stops at 22.5 and 45 degrees
- Cut depth of 2-9/16 inches at 90 degrees and 2 inches at 45 degrees
- Bare weight of 8.2 pounds
Blade-right means the blade sits on the right side of the motor. Blade position changes how easily you can see your cut line, so check it if you have a preference. These figures apply only to the DCS590, not every DEWALT saw.
What independent testers reported
TechGearLab tested the compact DCS391B on bevel changes, crosscuts, ripping and blade swaps. Its testers found the saw better for lighter work than for long rips. That’s a useful signal for DIY buyers who mostly cut shorter pieces.
Pro Tool Reviews tested the 60V FLEXVOLT DCS578 and praised its cutting power, tracking and guard behavior. Its focus leans toward professional workloads, which many occasional users won’t need.
The same outlet noted higher shoe friction on both the DCS578 and the DCS590. The shoe is the flat base plate that slides across the wood. More friction means you push a little harder through each cut.
Bare weight versus working weight
The DCS590’s 8.2-pound rating is the saw alone. A battery adds weight, and larger batteries add more. Check the battery’s weight before you buy if you’ll cut overhead or carry the saw around a job site.
What a ready-to-use DEWALT cordless setup really costs
The price on a “tool only” listing rarely matches what you’ll spend to make your first cut. The DCS590B box includes the saw, a blade-change wrench and a 24-tooth blade. It doesn’t include a battery or charger.
The DCS590WW1 kit adds an 8Ah DCB2108 battery, a DCB118 charger and a bag. We couldn’t verify a current kit price, so compare it against the bare tool plus a separate battery and charger.
If you already own compatible DEWALT 20V batteries, the bare tool is usually the cheaper path. Starting from zero changes the math, since you’re buying into a battery platform as well as a saw. Confirm compatibility for the exact model number before you order.
Runtime claims need a close read. DEWALT’s “up to 368 cuts” figure for the DCS590 is tied to 2×6 SPF lumber with the DCB2108 battery. It isn’t a promise for smaller batteries or other saws.
Ongoing costs stay modest, and no subscription is involved. Plan for replacement blades over time, and consider one matched to your material if the stock blade doesn’t give the finish you want.
DEWALT’s three-year limited warranty covers defects in materials and workmanship, not normal wear or misuse. Its stated terms also include one year of free service and a 90-day money-back guarantee where specified. Buy from an authorized seller and keep your receipt, because eligibility depends on both.

Drawbacks and cautions to check before you buy
- Bare-tool listings are easy to misread. A low price often means no battery and no charger.
- Compact saws have limits. Testers found the 6-1/2-inch DCS391B less suited to long rips.
- Shoe friction. Pro Tool Reviews noticed extra drag on two DEWALT models, though that’s a handling note, not a defect.
- “20V MAX” is a peak figure. It means maximum initial voltage; nominal voltage on the DCS590 is 18V.
- Retailer spec tables can be wrong. Northern Tool’s DCS590 table conflicts with DEWALT’s figures in several places, so trust the manufacturer sheet.
- Owner complaints are unconfirmed. One review of the corded DWE575SB reports blade, dust-adapter and cord complaints but doesn’t show its sample.
- Returns differ by store. DEWALT’s money-back guarantee isn’t the same as every retailer’s return policy.
We also couldn’t confirm recall status for any specific model. DEWALT’s safety notices page lists an older circular-saw notice, but we couldn’t load it fully. Check your exact model and date code against DEWALT’s official recall page.
Two alternatives worth comparing
SKIL 5280-01 for a low-cost corded start
The SKIL 5280-01 lists at $69.99 direct from SKIL. Home Depot showed it at $49 on November 2, 2026, though that price can change. It comes with a blade and bag, so it’s ready to use out of the box.
The trade-off is the cord, which keeps you near an outlet. Its stated maximum cut depth of 2-7/16 inches is also a bit less than the DCS590’s 2-9/16 inches. It suits budget buyers who work mainly in a garage or shop.
DEWALT DCS590B for full-size cuts on 20V
If you’re leaning toward a compact DEWALT, the DCS590B is the step up to consider. It brings full-size 7-1/4-inch cut depth while staying on the 20V battery platform. That matters if you already own 20V tools.
At $229 for the bare tool, it costs far more than the SKIL before you add a battery. It makes the most sense for buyers who already have the batteries or plan to grow their 20V collection.

Should you buy a DEWALT circular saw?
A DEWALT cordless saw is a strong fit if you already own DEWALT 20V batteries. In that case, a bare tool keeps your cost down, and the full-size DCS590 offers the most cut depth on that platform. Light-duty DIYers who mostly make short crosscuts can look at a compact model instead.
The biggest limitation is entry cost for new buyers. A battery and charger can push the total well past the bare-tool price. If you work near an outlet and want to spend less, a corded saw like the SKIL is the better value.
The evidence supports DEWALT as a sensible choice, but only once you’ve matched the model and package to your work. Confirm the exact model number, what’s in the box and the seller before paying.

Common questions about DEWALT circular saws
Does a “tool only” DEWALT circular saw include a battery and charger?
No. Tool-only versions like the DCS590B include the saw, a blade wrench and a blade, but no battery or charger. Kit versions such as the DCS590WW1 add both.
Should I choose a compact 6-1/2-inch or a full-size 7-1/4-inch saw?
Choose full-size if you need deeper cuts or rip long boards often. TechGearLab found the compact DCS391B better for lighter work. A 6-1/2-inch saw can suit occasional projects and shorter cuts.
Is 20V enough, or is FLEXVOLT worth the extra money?
For most DIY work, 20V is likely enough, especially with a full-size model like the DCS590. FLEXVOLT saws like the DCS578 target demanding, heavier cutting. They mainly make sense if you already own 60V batteries or cut hard and often.
