Cutting through 2x4s with a corded saw used to feel like dragging around a stubborn dog on a leash. DEWALT’s 20V MAX DCS570B cuts the leash—and still bites like a beast. If you’re already knee-deep in the DEWALT 20V ecosystem, this saw might just be the missing piece in your tool trailer. Let’s break it down and see what this cordless brute really offers.
Specs at a Glance
| Feature | Detail |
|---|---|
| Blade Size | 7-1/4 inch |
| Motor | Brushless |
| No-Load Speed | 5,200 RPM |
| Bevel Capacity | 57° |
| Depth of Cut (90°) | 2-9/16″ |
| Brake | Electric blade brake |
| Weight | ~7.5 lbs (tool-only) |
| Battery | Not included |
It’s tool-only, so make sure you’ve got a 20V MAX or FlexVolt battery on standby.
Power & Performance
This thing rips. The brushless motor spins at 5,200 RPM and feels every bit as gutsy as a corded saw. I pushed it through treated 2x material and 3/4″ OSB—no bogging, no smoke, no drama.
You’ll get full-depth cuts on standard framing lumber. 2x material? It eats it. Sheet goods? Feels like slicing warm butter with a hot knife.
No-frills here: pull the trigger and it moves. Fast.
Bevel & Depth
Sometimes beveling with cordless saws feels like guesswork. Not here. The DCS570B gives you a solid 57° bevel capacity, with positive stops at 22.5° and 45°. The markings are clear and the adjustments aren’t fiddly.
Cut depth is a strong point: 2-9/16″ at 90°, and just under 2″ at 45°. That means you’ll have no problem making clean passes through stacked plywood or beefy boards.
Runtime
With a 5Ah battery, DEWALT claims you’ll get about 330 crosscuts in 2×4 pine. In real use, I didn’t count cuts, but I ran it hard for an afternoon doing deck repairs and didn’t need to swap batteries.
It plays nice with all 20V MAX batteries. Toss a FlexVolt on and it’ll last even longer.
Biggest tip? Don’t skimp with a compact 1.5Ah battery—you’ll kill it faster than a mosquito in a bug zapper.
Handling & Balance
The saw feels solid in the hand. There’s no flex or rattle when you fire it up. At about 7.5 pounds, it’s not featherlight—but the balance is spot-on. You don’t feel like it’s fighting you during a long rip.
The top handle grip is rubberized and actually comfortable. Trigger travel is responsive and smooth, and you won’t need Hulk hands to keep it steady.
It’s got a rafter hook (thank you, DEWALT), which is one of those features you don’t realize you need—until you do.
Safety & Braking
The electric brake is fast. Let go of the trigger and the blade stops within a second or so. That’s more than just a convenience—it’s a real safety feature.
Visibility is decent, even indoors. It comes with an LED light that helps cast a shadow line when you’re cutting in lower light conditions. Nothing fancy here—just stuff that works.
Build Quality
This isn’t a toy. The shoe plate is rugged, the guards don’t feel cheap, and the blade change is quick with the onboard wrench.
One minor gripe: some users report the shoe plate gets scuffed easily. If you’re picky about cosmetics, grab a base plate cover.
This tool’s meant to get dirty, though—if you’re worried about scratches, maybe don’t use a circular saw.
What You Get (and What You Don’t)
Inside the box:
- The bare tool
- Blade
- Blade wrench
- Rafter hook (pre-installed)
You won’t get a battery or charger. So if you’re not already part of DEWALT’s battery club, budget for that.
Also, there’s no case or bag. It’s on you to carry it or make room in your toolbox.
Pros
- Brushless motor = power and efficiency
- Full 2-9/16″ cut depth
- Bevels to 57°, solid detents
- Electric brake
- Good ergonomics
Cons
- No battery or case included
- Dust port is meh
- Slightly heavy for overhead cuts
DEWALT vs. The Others
Compared to Makita’s XSH06Z, the DEWALT has better weight balance but falls behind in dust collection.
Milwaukee’s 2732‑20 offers similar power but comes at a higher price tag, and its brake isn’t quite as snappy.
The DCS570B doesn’t try to be the lightest or fanciest. It aims for power, comfort, and consistency. And it nails those three.
Final Thoughts
The DCS570B is everything a cordless circular saw should be—strong, predictable, and ready to get dusty.
If you’re already in DEWALT’s 20V line, this saw makes a ton of sense. It won’t babysit you, but it won’t quit either.
I’ve used plenty of saws that promised the world and barely delivered the block. This isn’t one of them. It’s built for pros, but friendly enough for the weekend warrior.
And hey—if your old saw is fraying cords like a spaghetti monster, maybe it’s time to cut the cord… literally.
