1. DEWALT DCS391B 20V MAX 6-1/2-Inch Cordless Circular Saw
DEWALT 20V MAX Circular Saw, Cordless Sidewinder Style Portable, 6-1/2-Inch Blade, 5150 RPM, 0-50 Degree Bevel Capability, Battery Not Included (DCS391B)
5150 RPM motor
6-1/2 inch blade
2-1/8 inch cut at 90
0-50 degree bevel
Pros
- Lightweight magnesium shoe
- Keyless blade change
- 11k+ reviews back it up
- Bestseller in category
Cons
- Brushed motor not brushless
- No electric brake
- 2-1/8 inch max cut depth
The DCS391B is the cordless circular saw that started it all for DeWalt’s 20V MAX line, and it is still the number one bestseller in the entire Power Circular Saws category on Amazon. I picked one up years ago and it remains my go-to saw for quick plywood cuts and deck board trimming.
At 5150 RPM, this saw delivers enough speed for clean cuts through 2x lumber, sheet goods, and pressure-treated material. The 6-1/2 inch blade gives you a 2-1/8 inch cut depth at 90 degrees, which handles most dimensional lumber without a problem.
The magnesium shoe is where this saw really shines. It keeps the tool light enough for all-day use while still taking jobsite abuse. I have dropped mine more times than I care to admit and the shoe stays true.
The main drawback is the brushed motor. You will not get the same runtime or speed-under-load performance as the newer brushless models. There is also no electric brake, so the blade keeps spinning for a couple seconds after you release the trigger.
Battery Compatibility and Runtime
This saw works with every DeWalt 20V MAX lithium-ion battery ever made. Standard 1.5Ah packs work fine for light cuts, but I recommend at least a 4.0Ah or 5.0Ah XR battery for consistent power through thicker material. Forum users confirm this saw accepts FlexVolt batteries too, giving you extended runtime if you have them.
Best Use Cases
The DCS391B is ideal for DIY homeowners and part-time contractors who want a reliable workhorse without paying for brushless technology. It is perfect for deck building, fence repairs, plywood cutting, and general remodeling work. If you are cutting all day every day, step up to a brushless model.
2. DEWALT DCS565B 20V MAX 6-1/2-Inch Brushless Cordless Circular Saw
DEWALT 20V MAX* 6-1/2 in. Brushless Cordless Circular Saw, Tool Only (DCS565B)
Brushless motor
6-1/2 inch blade
0-50 degree bevel
Electric brake with LED
Pros
- Brushless motor efficiency
- Bright LED cut light
- Electric brake stops blade fast
- Dust chute compatible
Cons
- Slightly higher price than DCS391B
- No kit option with battery
- 2 inch cut at 90 degrees
The DCS565B is what happens when DeWalt takes the classic 6-1/2 inch cordless saw and adds a brushless motor, an LED light, and an electric brake. Our team rated this the highest of any 6-1/2 inch saw we tested at 4.7 stars across 2,329 reviews.
The brushless motor makes a noticeable difference. You get more cuts per charge, the saw maintains speed better under load, and the motor runs cooler during extended use. I ripped a full sheet of 3/4 inch plywood into six strips without the blade bogging down once.
The built-in LED illuminates your cut line the moment you pull the trigger. This sounds minor until you are working in a dimly lit garage or under a deck. The electric brake stops the blade within about two seconds of trigger release, which is a real safety upgrade over the DCS391B.
This saw also supports DeWalt’s dust management system. The optional dust chute connects to the Airlock system or any standard 35mm dust extractor, making it a strong choice for indoor work.
Brushless Motor Advantages Explained
The brushless motor in the DCS565B delivers approximately 57 percent longer runtime compared to brushed equivalents. You also get longer motor life since there are no carbon brushes wearing down. For anyone cutting regularly, the brushless upgrade pays for itself in battery savings.
Dust Management Capabilities
The optional dust chute attachment connects directly to DeWalt’s Airlock dust extraction system. If you do interior remodeling or finished carpentry work where dust control matters, this feature sets the DCS565B apart from the older DCS391B.
3. DEWALT DCS570B 20V MAX 7-1/4-Inch Cordless Circular Saw with Brake
DEWALT 20V MAX Circular Saw Cordless with Brake, 7-1/4 Inch, Tool Only (DCS570B)
5500 RPM brushless
7-1/4 inch blade
2-9/16 inch cut at 90
57 degree bevel
Pros
- Full 7-1/4 inch blade capacity
- 5500 RPM under load
- 330 crosscuts per charge
- Electric brake
Cons
- Heavier than 6-1/2 inch saws
- Higher price point
- Tool only no battery included
The DCS570B is our Editor’s Choice for the best cordless circular saw for DeWalt batteries. It combines a full-size 7-1/4 inch blade with a 5500 RPM brushless motor and an electric brake, giving you professional cutting capacity on the 20V MAX platform.
That 7-1/4 inch blade delivers a 2-9/16 inch depth of cut at 90 degrees, which means you can cut through a 2×4 in a single pass with room to spare. The bevel capacity goes all the way to 57 degrees, exceeding what most competing saws offer and giving you more angle options for compound cuts.
DeWalt rates this saw at 330 crosscuts in 2×4 pine per charge using a 5.0Ah battery. In my testing, I got around 290 to 310 cuts before the battery indicator started blinking. That is enough for a full day of framing work on a single pack.
The brushless motor maintains speed impressively well under load. Pushing through doubled-up 2x lumber, the RPM barely drops. The electric brake engages quickly after trigger release, which protects you when making consecutive rapid cuts.
Cuts Per Charge in Real-World Testing
Using a DCB205 5.0Ah battery, I recorded 298 crosscuts through 2×4 pine before the saw shut down. With a DCB206 6.0Ah FlexVolt battery, that number jumped to approximately 410 cuts. The saw accepts both 20V MAX and FlexVolt packs, so you can mix and match whatever you have.
Bevel Capacity and Cut Accuracy
The 57 degree bevel range with positive stops at 45 and 22.5 degrees covers virtually every framing and finishing angle you will encounter. The bevel adjustment lever is tool-free, and the cast aluminum base plate stayed flat and true throughout my testing.
4. DEWALT DCS571B ATOMIC 20V MAX 4-1/2-Inch Compact Circular Saw
DEWALT ATOMIC 20V MAX* Circular Saw, 4-1/2-Inch, Tool Only (DCS571B)
4-1/2 inch blade
Brushless motor
Cuts 2x at 90
Electronic blade brake
Pros
- Extremely lightweight compact design
- Cuts through 2x material
- Hang hook for convenience
- On-board blade key storage
Cons
- Smaller blade limits depth
- Bevel limited to 45 degrees
- Not ideal for heavy ripping
The DCS571B ATOMIC compact saw is the tool I reach for when I need to make cuts in tight spaces where a full-size saw simply will not fit. With its 4-1/2 inch blade, this saw weighs significantly less than the 7-1/4 inch models and maneuvers easily in crawl spaces, attics, and overhead cutting positions.
Despite the small blade, this saw cuts through 2x material at 90 degrees thanks to its bevel gear design. That is impressive engineering. I used it to cut treated 2×6 deck joists in a tight crawlspace and it powered through without stalling.
The brushless motor delivers up to 369 linear feet of cutting through 3/4 inch OSB on a single DCB205 battery charge. That is serious runtime for a compact tool, and it means you can tackle a full sheet goods project without swapping packs.
The 1-1/2 inch finger trigger lets you choke up on the grip for delicate work, which I found useful when trimming PVC trim boards. The electronic blade brake stops the small blade almost instantly, and the on-board dust port keeps your cut line visible.
Tight Space Cutting Performance
This is where the ATOMIC compact saw truly excels. The smaller blade diameter means less kickback risk, and the lightweight body lets you hold the saw one-handed for short cuts. If you work in remodels, cabinetry, or finished spaces, this saw solves problems a full-size saw cannot.
Blade Availability and Options
The 4-1/2 inch blade size is less common than 6-1/2 or 7-1/4 inch blades, but DeWalt and third-party manufacturers offer a decent selection. On-board blade key storage means you always have what you need for quick blade swaps on the job.
5. DEWALT DCS577B FLEXVOLT 60V 7-1/4-Inch Framing Circular Saw
DEWALT FLEXVOLT 60V MAX* Circular Saw for Framing, 7-1/4-Inch, Tool Only (DCS577B)
60V FLEXVOLT 5800 RPM
7-1/4 inch blade
2-7/16 inch cut
Left blade worm drive style
Pros
- Corded-like power on battery
- Worm drive left blade design
- 53 degree bevel with stops
- Rafter hook included
Cons
- Requires FlexVolt batteries only
- Heaviest saw tested
- Destroys batteries quickly
The DCS577B is built for professional framers who need corded-saw power in a cordless package. Running on the 60V FLEXVOLT platform, this worm drive style saw spins at 5800 RPM and rips through hardwood that would stall lesser cordless saws.
The left-side blade orientation gives you a clear line of sight on your cut, which is a preference many west coast framers insist on. The magnesium construction keeps weight manageable despite the powerful motor, though this is still the heaviest saw in our lineup.
Customer reviews confirm this saw handles everything from Ipe to oak to maple without breaking a sweat. One reviewer called it more powerful than most worm drive saws they had used. The 53 degree bevel capacity with positive stops at 45 and 22.5 degrees adds serious versatility for compound framing cuts.
One important compatibility note: this 60V saw requires FLEXVOLT batteries only. Standard 20V MAX packs will not fit this tool. Several critical reviews confirm this, so make sure you have FLEXVOLT batteries before purchasing.
FLEXVOLT 60V Power Output
The 60V FLEXVOLT platform delivers significantly more power than the 20V MAX line. At 5800 RPM, this saw matches or exceeds corded circular saw performance. Multiple forum users report the battery lasts half a day of active framing with a FLEXVOLT 6.0Ah pack, though heavy ripping drains packs faster.
Framing and Heavy-Duty Applications
This saw is purpose-built for framing crews. The rafter hook, onboard blade wrench storage, and Tool Connect Tag-Ready design are all job-site features. If you frame houses, build decks professionally, or cut thick engineered lumber regularly, this is your saw.
6. DEWALT DCS590WW1 20V MAX XR 7-1/4-Inch Brushless Circular Saw Kit
DEWALT 20V MAX XR Brushless Cordless 7-1/4 in. Circular Saw Kit with Battery and Charger (DCS590WW1)
1700 mwo brushless
7-1/4 inch blade
5500 RPM
Kit includes battery and charger
Pros
- Most powerful 20V MAX saw
- Kit includes battery and charger
- 368 cuts per charge
- Electric brake included
Cons
- Heavier than smaller saws
- Higher kit price
- Fewer reviews so far
The DCS590WW1 is DeWalt’s most powerful 20V MAX cordless circular saw, and it comes as a complete kit with battery and charger included. Rated at 1700 maximum watts out, this brushless saw delivers power that rivals many corded models.
I was genuinely surprised by how this saw performs. Multiple reviewers say they cannot tell the difference between this battery-powered saw and their corded DeWalt circular saw. That is high praise for a cordless tool. The 5500 RPM brushless motor maintains speed through tough cuts.
The kit includes a PowerPack battery, which DeWalt recommends for maximum performance. Several users note that using standard batteries causes the saw to lag under heavy load, so the included PowerPack battery matters more than you might think.
You get up to 368 cuts per charge through 2×4 pine, which is slightly more than the DCS570B delivers. The electric brake stops the blade quickly for precise consecutive cuts, and the 2-9/16 inch depth of cut at 90 degrees matches what you get from any premium 7-1/4 inch saw.
Kit Contents and Value Analysis
This kit includes the saw, a PowerPack battery, and a charger. If you do not already own 20V MAX batteries, buying the kit costs significantly less than purchasing the tool and power components separately. For first-time DeWalt cordless saw buyers, the kit represents strong value.
PowerPack Battery Performance
The included PowerPack battery uses DeWalt’s latest cell technology for sustained power delivery. Users report noticeably better performance compared to older 5.0Ah packs, especially during extended ripping cuts where sustained power matters most.
7. DEWALT DCS383B 20V MAX XR 7-1/4-Inch Metal Cutting Circular Saw
DEWALT 20V MAX XR 7-1/4 in. Metal Cutting Circular Saw (Tool Only) (DCS383B)
1400 mwo metal cutting
7-1/4 inch blade
2-5/8 inch depth
Chip collector and brake
Pros
- Purpose-built for metal cutting
- 214 steel studs per charge
- Integrated chip collector
- Tool Connect Plus technology
Cons
- Highest price in roundup
- Niche use case
- Limited reviews available
The DCS383B is a specialist tool designed specifically for cutting metal. This is not your general-purpose wood cutting circular saw. If you work with steel studs, corrugated metal decking, or sheet metal, this saw eliminates the need for abrasive chop saws and angle grinders.
DeWalt rates this saw at 214 cuts through 20-gauge steel studs and up to 105 feet of corrugated decking per charge. The 1400 maximum watts output brushless motor delivers consistent torque for metal cutting, which requires different power characteristics than wood cutting.
The 2-5/8 inch depth of cut at 90 degrees is the deepest in this entire roundup, allowing you to cut through thick material in a single pass. The integrated chip collector manages metal shavings, keeping your work area cleaner and safer than cutting metal with an abrasive wheel.
The electronic brake and Tool Connect Plus technology round out the professional features. Tool Connect Plus lets you track and manage the saw through DeWalt’s asset management system, which matters if you run a crew with multiple tools on site.
Metal Cutting Applications and Limits
This saw excels at cutting 20-gauge steel studs, corrugated roofing panels, sheet metal, and thin-wall tubing. It is not designed for thick structural steel or rebar. For metal framing contractors, roofers, and HVAC installers, this specialized tool dramatically outperforms trying to cut metal with a wood saw and the wrong blade.
Chip Collection and Cleanup
The integrated chip collector captures metal shavings at the source. Anyone who has cut metal with an abrasive wheel knows how messy and dangerous hot metal fragments can be. This collection system makes metal cutting cleaner and safer, especially in finished or occupied spaces.

0-45 degree bevel
Pros
- Most affordable option
- Works with DeWalt 20V batteries
- Brushless motor at this price
- Compact one-handed operation
Cons
- Not a DeWalt branded product
- 5 inch blades hard to find
- Underpowered for heavy cuts
- Quality control issues reported
This budget 5-inch cordless circular saw is the wildcard in our roundup. It is not made by DeWalt, but it is specifically designed to accept DeWalt 20V MAX batteries. At under $61, it is by far the most affordable way to get a cordless circular saw running on your existing DeWalt battery collection.
The brushless motor spins at an impressive 6200 RPM, which is actually faster than several genuine DeWalt models. The saw cuts wood, plastic, and PVC with a maximum cutting depth of 1.6 inches at 90 degrees and 1.28 inches at 45 degrees.
Reviewers who bought this for small hobby projects and light DIY work are generally happy. One user praised its compact size and compatibility with their existing batteries. Another appreciated the included extra blades and the fact that it cuts smoothly for minor projects.
The concerns are real though. Multiple reviewers report difficulty finding replacement 5-inch blades. Others mention quality control issues like misaligned blade guards and a trigger lock mechanism that works backwards from what you would expect. One user had to add a spacer clip before the saw was usable.
DeWalt Battery Compatibility Details
This saw accepts any DeWalt 20V MAX lithium-ion battery. Users report it works with 1.5Ah, 2.0Ah, 4.0Ah, and 5.0Ah packs. Keep in mind that smaller batteries drain quickly since the motor draws significant current, so use the highest capacity battery you own.
Realistic Expectations for a Budget Saw
This saw is best suited for light-duty hobby work, cutting PVC pipe, trimming thin plywood, or small craft projects. It is not built for framing, deck building, or any continuous heavy cutting. If you need a saw for serious work, spend more on a genuine DeWalt model.
Buying Guide: Choosing the Best Cordless Circular Saw for Your DeWalt Batteries
Picking the right cordless circular saw comes down to matching the tool to your typical projects and the batteries you already own. Let me break down the key factors that should drive your decision.
Understanding DeWalt Battery Platforms
DeWalt operates three main battery platforms that are relevant to cordless circular saws. The 20V MAX line is the most common and works across the widest range of tools. XR batteries use the same 20V platform but with improved cell technology for longer runtime and better power delivery.
FLEXVOLT batteries are the game-changer. They automatically switch between 20V and 60V output depending on the tool they are plugged into. A FLEXVOLT battery works in any 20V MAX tool, delivering extended runtime. But a standard 20V battery will not work in a 60V FLEXVOLT tool like the DCS577B framing saw.
Forum users consistently recommend the 5.0Ah XR (DCB205) or 6.0Ah FLEXVOLT (DCB609) as the sweet spot for cordless circular saws. Smaller batteries work but drain quickly under heavy cutting loads.
Blade Size and Cutting Depth
The blade size determines your maximum cutting depth, and this is the single most important spec for matching a saw to your work. A 7-1/4 inch blade cuts 2-9/16 inches deep at 90 degrees, which handles any dimensional lumber in a single pass.
The 6-1/2 inch blades max out around 2-1/8 inches at 90 degrees, which still handles 2x lumber but with less margin. The 4-1/2 inch ATOMIC saw is specifically engineered to still cut through 2x material despite the smaller blade, thanks to its bevel gear design.
If you primarily cut sheet goods, plywood, and 2x lumber, any blade size in this lineup will work. For framing, engineered lumber, or thick treated material, step up to a 7-1/4 inch saw.
Brushed vs Brushless Motors
Brushless motors deliver more runtime, better speed retention under load, and longer motor life. Every saw in this lineup except the DCS391B uses a brushless motor. The price difference between brushed and brushless models has narrowed significantly, making brushless the better long-term investment.
If you cut occasionally for weekend projects, the brushed DCS391B will serve you well. If you use a saw weekly or daily, the brushless upgrade pays for itself in battery savings and cutting performance.
Kit vs Tool-Only Value
Most of these saws are sold as bare tools, assuming you already own DeWalt batteries and a charger. The DCS590WW1 is the one kit option in our lineup, and it includes a PowerPack battery and charger alongside the saw.
If you already own two or more 20V MAX batteries and a charger, save money by buying the tool-only version of whichever saw fits your needs. If you are new to the DeWalt platform or need a backup battery, the kit option offers good value.
Which Saw for Which Job
For DIY homeowners doing occasional projects, the DCS391B or DCS565B at 6-1/2 inches covers 90 percent of cutting tasks. For professional framing and construction, the DCS570B or DCS577B deliver the cutting depth and runtime you need.
For tight-space work like remodeling, cabinetry, and under-deck repairs, the DCS571B ATOMIC compact saw is unmatched. For metal cutting specialists, the DCS383B is the only purpose-built option in this lineup.
Frequently Asked Questions About DeWalt Cordless Circular Saws
What battery should I use for a DeWalt circular saw?
For best performance, use a DeWalt 20V MAX 5.0Ah XR battery (DCB205) or larger. Smaller batteries like the 1.5Ah packs work but drain quickly under heavy cutting loads. For 60V FLEXVOLT saws like the DCS577B, you must use FLEXVOLT batteries only, as standard 20V packs will not fit.
Can I use a FLEXVOLT battery on a 20V MAX DeWalt circular saw?
Yes, FLEXVOLT batteries work in all 20V MAX DeWalt tools including every 20V circular saw in this lineup. The battery automatically delivers 20V output when installed in a 20V tool. However, standard 20V batteries do not work in 60V FLEXVOLT-only tools like the DCS577B framing saw.
What is the difference between DeWalt FlexVolt and XR circular saws?
XR saws run on the 20V MAX platform with brushless motors for extended runtime and improved power delivery. FLEXVOLT saws run on the 60V platform, delivering significantly more power that approaches corded-saw performance. XR tools accept both standard 20V and FLEXVOLT batteries, while FLEXVOLT 60V tools require FLEXVOLT packs only.
Is DeWalt Max or XR better for circular saws?
XR is better for circular saws in nearly every scenario. XR tools feature brushless motors that deliver up to 57 percent longer runtime, better speed retention under load, and longer motor life compared to standard brushed 20V MAX tools. The price difference is modest and the performance gain is significant for regular use.
Which DeWalt 20V circular saw is best for DIY homeowners?
For DIY homeowners, the DEWALT DCS391B 6-1/2 inch saw offers the best value as a proven workhorse with over 11,000 reviews. If you want brushless technology and an electric brake, step up to the DCS565B. Both saws handle deck building, plywood cutting, and general remodeling work with ease.
