DeWalt 20V MAX XR 7-1/4 in. Circular Saw (DCS570B) Review

What the DCS570B actually is

The DCS570B is DeWalt's brushless 7-1/4 in. sidewinder for the 20V MAX platform, sold as a bare tool. It is the saw a DeWalt owner buys after the 20V MAX drill driver and the 20V MAX impact driver, using the batteries already on the charger.

It is a blade-right sidewinder with an aluminum base, an electric brake and a brushless motor. It is not a worm drive and not a FLEXVOLT 60V saw. Those distinctions matter for torque, and we return to them under Features.

DeWalt's product page footnote (checked October 10, 2026) states that maximum initial battery voltage is 20 volts measured without a workload, and nominal voltage is 18. In other words, this is an 18-volt-class saw with 20V MAX branding, the same as every other tool on the platform.

This is a documentation review. We compared DeWalt's spec sheets, warranty terms and published owner reports. We did not run cuts of our own, and nothing below should be read as a test result.

Who the DCS570B is best for

The platform decides this purchase more than the saw does. A circular saw is a second or third cordless tool for most buyers, and the battery stable you already own should carry most of the weight.

• DeWalt 20V MAX owners who already have at least one 5.0Ah pack and want a saw without buying a second charger
• Deck and fence builders at home cutting 2x6, 2x8 and 4x4 stock where a 2-9/16 in. depth of cut clears the material in one pass
• Sheet-goods cutters breaking down 3/4 in. plywood and MDF in a driveway where a cord is a nuisance
• Renovators who want the 57-degree bevel for trim, roofing and compound work the cheaper saws cannot reach
• Buyers who value warranty terms, since 3 years limited plus 90 days money-back is the best paper coverage in this cluster

Who should skip it

Not every buyer should pick the yellow saw, even a good one.

• Buyers with no batteries yet: the Ryobi ONE+ HP saw is listed at $139 on Ryobi's site as of October 2026 and starts a cheaper platform
• Daily framers who need maximum torque: Milwaukee's M18 FUEL saw lists 6,000 RPM and a 2-5/8 in. cut, and DeWalt's own DCS574 is listed as up to 54 percent more powerful
• Overhead and ladder work: a 7.5 lb bare saw plus a 5.0Ah pack is a two-hand tool; a 6-1/2 in. compact saw suits that job better

What is in the box and what is not

The B in DCS570B means bare tool. DeWalt Canada's page (checked October 10, 2026) lists the saw, a 7-1/4 in. 24-tooth carbide blade and a blade-change wrench. The battery and charger are sold separately.

That changes the real cost. A circular saw pulls far more current than a drill, so DeWalt's documentation pairs it with 5.0Ah packs and larger. If your only battery is the 1.3Ah or 2.0Ah pack that came with a drill kit, plan on buying a bigger one.

DeWalt also sells the saw in kits, including a version with a 5.0Ah POWERSTACK pack that surfaced in retailer listings during our search. We could not read a manufacturer price for either the bare tool or the kits, so we do not quote one.

For the battery math itself, our note on volts, amp-hours and watt-hours explains why a 5.0Ah 20V MAX pack holds roughly 90 watt-hours and why that figure, not the voltage, predicts how many cuts you get.

How the pricing is structured

DeWalt does not publish a list price for the DCS570B on the product pages we could read on October 10, 2026. The US product URL returned the DeWalt homepage, and the Canadian page lists no price. We also could not read the Lowe's or Home Depot listings, which blocked automated access.

So the honest pricing statement is this: the saw is sold bare, retailers set the street price, and the kit versions bundle a battery and charger at a higher figure. Check the current retailer page before you decide.

One structural note that does not depend on the exact number: the bare-tool price is only the real price if you already own a battery large enough to run a saw. Add a 5.0Ah pack and charger if you do not, and compare that total against the Ryobi kit and the Milwaukee bare tool.

Ease of use: what the 4.3 is built from

The score comes from the spec sheet and from what published reviews report about handling, not from cuts of our own.

In favour: the 7.5 lb bare weight is the lightest of the three saws in this cluster by DeWalt's own figure, and the electric brake stops the blade after the trigger is released. Pro Tool Reviews' write-up of the DCS570 described the brake as very fast and praised the aluminum base and smooth bevel adjustment with detents at 22.5 and 45 degrees.

Against: the same review disliked the push-in trigger safety, preferring the push-down style found on other saws, and a retailer reviewer found the handle awkward when the blade was raised for thin stock. Rafter hook availability is unclear in the documentation: DeWalt Canada's page lists one among the included items, while Pro Tool Reviews flagged its absence on the DCS570. Check the box.

We hold the score at 4.3 rather than higher because of the trigger complaint and the hook ambiguity.

Features: what the 4.0 is built from

DeWalt's spec sheet (checked October 10, 2026) lists a 5,500 RPM no-load speed, a 2-9/16 in. depth of cut at 90 degrees, 2 in. at 45 degrees and a 57-degree bevel capacity. Those are full-size sidewinder numbers: 2x lumber clears in one pass at 90 and at 45.

The 57-degree bevel is the widest in this cluster. Milwaukee's M18 FUEL saw lists 50 degrees and Ryobi's ONE+ HP saw lists 56. For roofing and compound trim, the extra degrees occasionally matter.

The ceiling is torque. The DCS570 runs on an 18-volt-nominal pack, and DeWalt's own documentation for the newer DCS574 claims up to 54 percent more power than the DCS570 paired with a 5.0Ah battery. Pro Tool Reviews likewise rated the DCS570 at 8.1 out of 10 and called it a legitimate corded-sidewinder replacement with less torque than a worm drive or FLEXVOLT saw.

Dust extraction is not listed as a feature on the pages we read, and an LED work light is not mentioned on the Canadian page. Milwaukee's saw lists both. That is why Features sits at 4.0, below the red saw's 4.7.

Value: what the 4.2 is built from

Value here is the capability per dollar against the tier above and below, with the caveat that DeWalt does not publish the dollar figure.

Against the tier below, the Ryobi ONE+ HP saw at $139 (Ryobi's site, October 2026) matches the DeWalt's 2-9/16 in. cut depth and nearly matches its bevel, so the DeWalt has to justify its premium on the warranty, the lighter weight and the platform.

Against the tier above, the Milwaukee M18 FUEL 2834-20 is listed by retailers at roughly $249 to $279 bare as of October 2026, with 6,000 RPM, a 5-year tool warranty and up to 750 cuts per charge on Milwaukee's largest pack.

For an existing DeWalt owner, the DCS570B is the cheapest route to a capable full-size saw because the battery cost is already sunk. That is where the 4.2 comes from. For a buyer starting fresh, the value case weakens, and our best cordless circular saw guide walks through that decision.

Support: what the 4.2 is built from

DeWalt's warranty page (checked October 10, 2026) states a 3-year limited warranty on power tools covering defects in materials and workmanship, a 1-year free service period during which DeWalt will maintain the tool and replace worn parts caused by normal use, and a 90-day money-back guarantee from purchase or delivery.

The 90-day return window is the part most buyers overlook. It means a saw that feels wrong in the hand can go back without arguing about defects.

Milwaukee's product page shows a 5-year tool warranty logo, which is longer on the headline number. DeWalt's 1-year free service and 90-day return terms are more generous in the first year. We score DeWalt's support at 4.2 and Milwaukee's at 4.5, reflecting the longer total coverage on the red side.

Parts availability for 20V MAX tools is broad because of the platform's size, which is the same argument we made in the Milwaukee M18 vs DeWalt 20V comparison.

What published owner reports say

We could not read the Home Depot or Lowe's review pages on October 10, 2026; both blocked automated access. What follows comes from professional reviews and retailer review snippets surfaced in search, and should be weighted accordingly.

Pro Tool Reviews scored the DCS570 at 8.1 out of 10, praising the fast electric brake, the aluminum base and the bevel detents, and criticising the push-in trigger safety and the lack of a rafter hook on the unit they covered.

Retailer reviewers reported running a full day on a 9Ah pack with charge remaining, and one cautioned that a dull blade drains the battery noticeably faster. A retailer listing claims 330 crosscuts in 2x4 pine per charge; DeWalt's own page does not state a cuts-per-charge figure, so treat that number as a retailer claim.

A Lowe's summary surfaced in search noted that a few customers reported battery-life problems without specifics. We could not verify the count or the context.

Alternatives worth a look

Three saws sit close to the DCS570B in price or platform.

Milwaukee M18 FUEL 7-1/4 in. (2834-20): 6,000 RPM, 2-5/8 in. cut, 50-degree bevel, LED, dust port, rafter hook and a 5-year tool warranty, per Milwaukee's page checked October 10, 2026. Choose it if you are on M18 or want the most power in this cluster. Otherwise choose the DeWalt if your batteries are already yellow. Read our Milwaukee M18 FUEL circular saw review and the head-to-head comparison.

Ryobi ONE+ HP 7-1/4 in. (PBLCS302B): $139 on Ryobi's site as of October 2026, 2-9/16 in. cut, 56-degree bevel, 3-year warranty. Choose it if you are starting from zero batteries or your saw will see a few weekends a year. Otherwise choose the DeWalt for the lighter body and the better warranty terms. Read our Ryobi ONE+ HP circular saw review.

DeWalt DCS574 (POWER DETECT): DeWalt Canada's page lists up to 54 percent more power than the DCS570 with a 5.0Ah battery when paired with an 8Ah pack, the same 2-9/16 in. cut and a kit (DCS574W1) with an 8.0Ah battery. Choose it if you frame regularly on 20V MAX. Otherwise the DCS570B is enough for homeowner work.

Buy it if / Skip it if

The decision in one list each.

• Buy it if you already own DeWalt 20V MAX packs of 5.0Ah or larger
• Buy it if your work is decking, fencing, sheet goods and the occasional wall, not daily framing
• Buy it if warranty terms matter: 3 years limited, 1 year free service, 90 days money-back
• Skip it if you own no batteries and could start on Ryobi for $139 or Milwaukee for more power
• Skip it if you need an LED, a dust port and a confirmed rafter hook, which Milwaukee lists and DeWalt's page does not
• Skip it if you frame most weekends, where the DCS574 or an M18 FUEL saw has more headroom

Frequently asked

Short answers to the questions people type before buying this saw.

Bottom line

The DCS570B is the right circular saw for a DeWalt 20V MAX household and an ordinary one for everyone else. Its spec sheet covers homeowner work with room to spare, its bare weight is the lightest in this cluster, and DeWalt's 3-year, 1-year, 90-day warranty stack is the best paper coverage of the three.

Its weaknesses are the unpublished price, the bare-tool packaging and a torque ceiling that DeWalt itself has moved past with the DCS574. If your charger already has yellow packs on it, buy the DCS570B and a 24-tooth framing blade. If it does not, read the best cordless circular saw guide first, and pick the platform before the saw.

As with the first power tools guide, the rule holds: buy the battery platform you will still want in five years, then buy the saw that runs on it.

Best for

Homeowners and serious DIYers who already own DeWalt 20V MAX batteries and want one cordless saw for decking, sheet goods and the occasional framing job.
