DEWALT ATOMIC 20-Volt MAX Cordless 4-1/2' Circular Saw Review DCS571 Power with New FlexVolt Battery

---------------------------------------------------------------------------------------------------
The DEWALT Atomic 20V Brushless 4-1/2″ Circular Saw is a lightweight and compact saw designed for pro use all the way down to DIY.  The size of the saw and blade makes it comfortable and easy to use, even for people who are new to wood saws.

The DEWALT Atomic 20V Circular Saw will be a popular saw due to its easy one-hand cutting on thinner materials.  For small jobs or quick work, this saw is easy to get out, travel with and put away.  It will not take the place of a traditional 7-1/4″ circular saw, but more as a supplement for smaller jobs and in tight spots where a standard circular saw won’t fit.

4-1/2" Circular Saw Design

When looking at the DEWALT Atomic 20V Brushless 4-1/2″ Circular Saw from the side, you will note a few places the saw was designed to hold with a single hand.  The trigger has a multi-level sort of “S” shape that allows for a forward or rearward grip, each having access to the trigger.  This is ideal for tight places in a more professional application.

There is a secondary or auxiliary handle above the motor and just slightly to the rear of the blade.  This is a great place to hold the saw with a second hand for precise cuts.   We found the auxiliary handle comfortable for cutting sheet goods.  The auxiliary handle is also removable if you need the saw for tight areas.

Height and bevel adjustments have a familiar feeling to a traditional circular saw.  The Atomic Saw will bevel to 45º with a depth of cut of 1".  You can adjust the stop at 90º with a Philips head screw for improved accuracy. At 90º you have a 1-1/2″ cutting capacity that will just cut 2x dimensional lumber.  This saw will struggle to fully cut 2x lumber that is warped as we show in the video.

Finding 4-1/2″ Blades

The DEWALT Atomic 20V Brushless 4-1/2″ Circular Saw comes with a Carbide tipped 24-Tooth 4-1/2″ blade.  This blade works well for rough cuts but leaves a lot to be desired when used for trim or siding.  We have listed multiple blades above that will fit this saw and increase the cut quality.  Unfortunately, if you purchase this in a big box store, you will most likely not find any blades to fit this saw in the store.  we feel this will quickly change once more of these 4-1/2" saws become more popular with pro-grade brand names.

For now, we can look and find decent blades on Amazon.

Hey Brian. Thanks for the review. I've been using this saw on a near daily basis as a professional remodeler / contractor and although it does have a few minor quirks on occasion such as the vac adapter & allen key for blade changes needing to be better secured or stored separately to avoid losing. I've found it to be an incredibly versatile tool to have on the job site. I refer to it as my trim saw & it is perfect for flooring rips & fitment cuts. It's quick, lightweight & easy to use for accurate cuts in a multitude of materials. It's pretty much, my go to circ. saw on most of our remodeling projects. it takes care of about 80-90% of the tasks we use a circular saw for every week. It performs well and is a quicker & easier to alternative to my DCS577 Flexvolt for most applications, especially for the less experienced guys. Plus, you just can't beat the accuracy & great line of sight you get from using a blade-left saw.


Couple of tips- for best performance when cutting any kind of wood, I use the DIablo 4 3/8" 36T Carbide finish blade. Super fast & pristine cuts, with Zero Tearout (night & day difference to stock blade).


#2. You can actually get Turbo Diamond blades with 3/8" arbor or use an adapter from amazon etc. (3/8-5/8"). WIth the right diamond blade, it is actually capable of performing clean (dry) cuts in tile, Quartz or even 2cm stone on occasion.


#3. The factory blade or 60T HSS blades will also work well for cutting the newer types of shower waterproofing panels, kerdi, schluter, Wedi Etc. Even Cement backer board on occasion with the 60T.


Thanks for all your hard work, honest reviews & fantastic content!! Especially your dedication to producing high quality, entertaining & informative content right now, with such limited resources. It's most appreciated!!👍👍👍


Keep up the great work, you just earned another subscriber!

I am a contractor and I use this on a daily basis for framing, sheet8ng and even finish carpentry. I just did some cuts on stained oak 3/4" trim, taped it with masking tape and had a perfectly smooth finish cut. I used the blade it came with, no issues. 🙏🏻😁

[brianf]

I always wanted one of these and recently a guy on a remodeling job I was doing had one and I finally got a chance to use one, I really liked it, its great for doing some quick cuts especially were space is limited and it's so lightweight I can take it with me everywhere I think I might need a saw, I immediately when out and bought myself one, right now H.D. has them on sale for $99 and that's a great price for this tool, they don't go on sale too often, so I'd suggest getting down there and buying yourself one ....11/12/21

I found this video extremely helpful and purchased this item due to your video review. The reason I bought this for my husband was to help him with a picked fence. The farm doesn't have available outlets so the batteries are a plus. Thank you for dropping all those jewels on the description below. Thank you even I can understand how to use this tool.

Been a plumbing apprentice for a year now and bought one of these because we cut lumber for backing all the time. A sawzall was too much work and inaccurate. A normal circle saw seemed overkill. This was the perfect middle. Perfect for pocket cuts and patching holes in floors. Tool is awesome.

[codybavar]

I didnt need it, but I bought this saw to have a new gadget. I love it! It is always in my truck right next to my Dewalt 60 volt 7 1/4". The only downsides are yes, loosing the allen tool, wish it would cut just 1/8" deeper, the screws leaves gowges in the rip guide, and its left handed. Not a fan of left handed, but on occasion that characteristic comes in handy. Besides for that, I love it. Its rips fantastically, lets me get into tighter spaces, and actually has a bit of power for its size.

[TheBigWrist]

I bought this 4 1/2 inch saw on a whim. I did not not need a another saw, but what the heck! Wow, what a great saw! It is my go to saw for most of my sheet goods and cut off needs. A great little beast of a saw.

[Influnc]

I’m getting one now. I really like the slim compactness when I have smaller projects and I don’t want to haul around my circ saw.

[hasandilek]

probably the best 'cordless' saw for flooring and trim work. perfect sight of line...and they should call this saw a "recircular" saw, its like a circular saw with a reciprocating saw grip.

[btrswt]

These little circular saws are actually very handy. Making a quick cut or two is easy. I find it to be less intimating than a 7 1/4" saw so it would be good for those people that are timid with larger tools.

[mikegoswami]

Brian, I am a dewalt man, just baught a dewalt circular cordless saw and a planer, also have the saw in your video. Love your demo. I own a UPS store in Austin and build crates for customers and boy I tell you these tools have made my life easy and more than half the time with the corded tools. Thanks

[northcackalacky]

I've really appreciated your reviews. Dewalt forced me out of my favorite 18v tools.
3 days of shopping and watching your revenues saved me $ and mistakes.
I rounded up 11 miscellaneous 20v Dewalt tools and
4 batteries and free $90
rolling toolbox! $1100

DCKTS600M2 combo kit was an accidental find @ HD
$499

I'm a Carpenter, I bought that saw about 18 months ago and I Love it, its great for small framing jobs and it's small enough to fit in my rolling bag so I always have it with me, Awesome Saw, Well Built, Buy One

Actually, I wasn't surprised that the dust collection port operated well.
With the vacuum on, the port is held in place by suction.
If there was a manual lock on it, and someone tripped over the vacuum hose, it could pull the saw from the operator's hand and cut them.
That's the reason Apple created MAGLOCK for their laptops.

[nikko]

I purchased this saw on June 27th 2024, as a kit. I read the manual and came across the the dust collection section, turns out that the manual reads that the kit comes with a dust collector bag. I called Dewalt and, sure enough, they mailed me out a bag to use with this particular saw. If you purchase the kit version be sure to read your manual to see if it says that a dust bag should be supplied....🤗🤗🤗

[IdahoIsaiah]

This little dewalt saw it a beast at frameing demo! I got one and it gets into some tight spaces. Good purchase

[johnclarke]

I just got my DeWalt DCS571B. I bought a Power Stack battery to go with it. It assembled together very easily. It runs fine on my standard 1.5 ah batteries, some I have had for ten years it has cut everything that I have asked it to cut with ease. I don’t think it needs anything but the entry level batteries for most jobs. I am not a journeyman carpenter but I occasionally demand a lot from my tools, often outside their normal abilities- just ask my 20 odd Stihl chainsaws.😊

LOVE THIS SAW ESPECIALLY after adding Rockler's DUST RIGHT FLEXIPORT DUST CANISTER. Only wished it had a light

[HelsinkiPink]

I love how this saw dumps sawdust away from me. Very important since I use this usually in awkward positions or tighter quarters, so dust kicking up in my face would suck. Love this thing. Done so much more than I thought it would. If I did have one wish with this, the shoe could be a be improved on . The rolled steel sometimes would ride up on guides or rulers I use as a guide, where as your typical saws will butt up on it nicely.
