Almost ordered 577, I didn't know when it was so big and heavy. Looks like I'll take 573. Thanks for the great video! 👍👍👍

[@stevenfoust3782]

Good comparison video. I like the flex volt advantage concept but I run several 60v saws for everything. The motor is super smooth allowing precision cuts from framing lumber to cabinet end panels with the proper blade and cut depth set for the material.

[@MyFortressConstruction]

Yeah, the 573 seems to be just as capable, but if you need just 60v, then 578 is a no-brainer.

[@AttnDefDis_]

You are super entertaining and this comparison is exactly what I was looking for. Thanks!

Thanks pal I'm gonna roll with the flex advantage saw. my brushed 6 1/2 lasted me ten years it just died yesterday. You video helped make the decision, keep it up!

[@MyFortressConstruction]

It's been a good saw, just check blade alignment with the shoe. I have found one that was off by a 16th from one side of the blade to the other. HD has a couple of sales right now, so it's a good time to get one.

[@BH-ip6ds]

Thanks for a great overview. Perfect for me as I have Dewalt batteries and looking to get rid of my prehistoric corded 7 1\4 circular saw. Now if I could only find the same sales you did to get the 573...

I just picked up the 578. Couldn’t find the 573 with an included flex volt battery. Just going to wait for a sale on the batteries to pick an extra one up. Just doing DIY/homeowner stuff, plan on building a shed. I wanted the most powerful for a good deal. The DCS578X1 package seemed like a good deal with the 9ah(3ah lol) battery and 6amp charger. I’ll pick up one more when they have a deal going on. Thanks for the demo!

[@MyFortressConstruction]

578 is a great saw. The 573 is just good for someone who wants to be able to use 20v batteries as a backup, so good choice.

[@marcowens3522]

[@JesseBCO18]

I am a DYI guy who wants a right side 7 1/4" that doesn't require flex volt batteries. What do you suggest?

[@MyFortressConstruction]

I am afraid a 7 1/4" running on regular 20v batteries just doesn't "cut it". I mean it will be fine for most diy stuff, but when you really need to cut some heavier stock it's going to struggle. Do you need that extra 7/16" depth of cut a 7 1/4" gives or is it just what you're used to? If so you'll have to make due, but I'd vote for the dcs391 or dcs565. There is a "power detect" version that when paired with an 8ah 20v battery will give you the torque needed, but my recommendation is to get the flexvolt advantage and find a cheap flexvolt battery on OfferUp or marketplace. You won't regret having a capable saw when you need it.

[@davekushman2363]

I’ve got a DCS391B which is the brushless 391 and the 4 1/2 DCS571 I love them both they both have have their time and place and are super useful but I want to get my hands on one of the 7 1/4 dewalt circ saws. Only problem I have is all the 6 1/2 saws are right handed saws which I love and all of their 7 1/4 saws are left handed saws which I can’t seem to ever get comfortable or accurate using. I really wish dewalt made each model in both right and left variations

[@MyFortressConstruction]

Yeah, I was using the rear handle and 6 1/2" until I got the 578 and it took a little to get use to but on certain cuts it's better than a blade left because of where the shoe falls. Also, If you ever cut pressure treated lumber, a flexvolt saw will definitely give you the boost in power to cut miters and bevels.

[@EireFirst2024]

Persevere with left side blade man... It'll change your life 👍😂

[@wondon2992]

I’ve had four of the 391 got the 571 and sold after about 8 months . The 391 is faster idk why DeWalt took power away from the 571? You can read the days side by side it’s true

[@snoopiedadawg5920]

This guy’s got it for sure 😭

[@MyFortressConstruction]

Insanity? Stupidity? A winning personality? Lots of DeWalt tools? 😂

[@jeffnorbert1871]

Have been seriously considering the 391. Free with a $200 kit of stuff I don't need but would "part out". 391 is $129 by itself locally. The brushless has similar performance. I don't care about the hook. The light I could live without. $169 locally. That bevel adjustment knob stripping out on your 391 really makes me hesitate. Tool designers rate a big "fail". Features but rarely get the basics right. Thanks for the video.

[@MyFortressConstruction]

Yes, so the 391 has had some longevity issues. I've gone through 3 of them in the last 5 years. Two of them the motor shaft started wobbling and it just sounded like it was dying before that, and the third one has been fine except for the bevel knob stripping. I'm curious to see how the brushless one performs long term. The only saw I've seen that has withstood the rigors of a construction site longer than 3 years has been the old worm drive skilsaws. If it weighs as much as a tank, it probably is one. It's not that the plastic saw casings break, it's that all of the internal parts are anchored to plastic via screws and glue and with all of the vibration they eventually start moving enough to allow internal things to break. It would be nice if DeWalt would make a 60v full metal beast of a saw.

[@G19Jeeper]

You would be better served with the 565 if you are concerned about longevity.

[@greendilldoz71]

Great video

[@benshapira5636]

I now want to buy a saw .. What is the most worthwhile? 573 or 578 I'm an amateur and it's for home use, thanks

[@MyFortressConstruction]

DCS391 is cheap and will do most everything for a homeowner/DIY. DCS573 is excellent with Flexvolt batteries and definitely more powerful than it's 6.5" little brothers, but not super strong with 20v batteries. DCS565 is more feature rich than DCS391, and a little boost in power and runtime, but not as powerful as the 573 with a Flexvolt. So if I was only picking one I'd go with the 573, but if I didn't plan on getting Flexvolt batteries then I would get the 565, and if I just wanted a cheap plywood/2x4 cutter I'd get the 391.

[@benshapira5636]

@@MyFortressConstruction Thank you so much bro

[@write2nick]

@@MyFortressConstruction Thank you. I will be getting 391 since I’m going to be cutting 1 or 2 plywood per DIY project. Also I don’t see myself working with anything more than 2 inches thickness of wood.

[@MyFortressConstruction]

@@write2nick Yeah, it's not super powerful, but I was able to do everything I needed to build an entire house with it. A sharp blade is important and the more teeth on the blade the more chance of burning and bogging down. It performs best with a 24 tooth blade (I usually buy a Diablo two pack when it comes on sale for $12 at HD).

[@loucifer323]

With circular saws you always want the most powerful you can get so the 578 is the one to get

Yes, US allows the funky 60v mambo jambo, but it's 54v in other countries. Same battery though.

[@bobbylibertini]

Trying to figure out the difference between the DCS565 and the 566, which came in the 7 tool XR combo kit I bought. Only thing I can see is that the 566 doesn't have a rafter hook. Anything else?

[@MyFortressConstruction]

There's a DCS566? I haven't ever seen that one. Guessing it is a slight variation, maybe to cut down costs if it's missing stuff?

[@kyleallen1858]

Sweet$ good to know I just bought the 578 😊

[@MyFortressConstruction]

👍 Great saw. Just check that the blade is properly aligned with the shoe. I got one that was off by almost an 1/8". Just measure from blade to shoe edge at front and back of the blade. Should be identical measurements.

[@darren92redrum67]

The brushed 391 costs £100 in UK on sale!😥

[@kyleallen1858]

How did you buy these for so cheap???

[@MyFortressConstruction]

I just watch for sales (buy kits and sell the batteries) and occasionally find good deals on eBay and from a local liquidator who buys pallets of tools from Home Depot.

[@kule510]

How did you get them that cheap they are over $500 Bucks in California.

[@MyFortressConstruction]

Since I've made the video the prices have definitely increased. I was buying them during sales and at a local liquidator or selling the battery to offset costs.

[@hmtrimworks7148]

@ 15:24 “The big monstrous saw” as you say, is a worm drive and it is a right-handed saw not a left-handed saw… If the blade is on the left side it is built for right handed person… (it’s a left bladed saw not a “left handed saw”)

[@MyFortressConstruction]

I hear ya, but it's really just vernacular. It's neither a right or left-handed saw as they're made to be ambidextrous. You're referring to line of sight, but different people, regardless of hand preference, use both. Around here people speak of the saw according to the position of the blade (blade is on the "left hand" so left-handed saw). They also call them wormdrive saws like you, because of the original Skilsaw version, but Skil owns that patent so its not a wormdrive. So it's actually a blade left, rear-handle saw.

[@renetessier2051]

These are also wormdrive style saws as it’s just a side winder with a rear handle. A true worm driver has worm drive gear and requires oil. This gear provides more torque. Only cordless worm drive on market is made by skil.

[@interman7715]

The 578 has waaayyyy more power then the 573 ,just plonk them into full depth rips into hardwood, that will show the difference.

[@MyFortressConstruction]

If it takes hardwood to show the difference then the 573 is just fine. I wouldn't use a circular saw to cut oak/maple or something like that anyways. The hardest wood to cut for most contractors are LVLs and pressure treated stair stringers, which the 573 does just fine with a Flexvolt battery.

[@interman7715]

@@MyFortressConstruction Or even full depth rips into pine ,the 578 shows much more power.

[@The2006200]

Right hand blade is a deal breaker for me. wish they all came in a left hand.

Yeah, I use to only use blade left saws and prefer the lightweight 6.5", but now I alternate. Blade right has its uses, but not for everyone.

Are you looking for the rear handle style (DCS577) or the sidewinder (DCS578)? There is also the 18v/54v sidewinder (DCS573). If you google those model numbers they should pull up.

[@DirkDigglerbig1]

I bought the DCS578, I guess the 6ah doesn't have enough juice to power the saw.

[@MyFortressConstruction]

The 578 is a great saw and shouldn't have an issue when you're using the 6ah (2ah 60v). Mainly just runtime will be an issue. Does it seemed to lack power to you?

[@DirkDigglerbig1]

@@MyFortressConstruction I believe I figured out the problem, I called a dewalt service center and they asked me if I ever used the 60 volts. I replied I always have. They explained to me that all the tools I used where not pulling the 60 volts but only 20 volts. I never really used anything other than a drill and an impact drill with that battery. Dewalt concluded that the 60 volt cells must of gone bad, because they where never used. Unfortunately the battery is out of warranty, it had a date code of 2017. They explained to me that it should work with the saw. Sucks man, I actually returned the saw to home depot thinking it was defective. I turned around and bought the worm drive. But that worm drive is a beast it feels like a chainsaw on your hand, im just a beginner I'm not even a carpenter, I think I bought an overpowered machine, for occasional use. I do want to learn carpentry, im probably going to go back to the DCS578, it just felt better in my hand. I have the gift of being ambidextrous, but the right side saw felt way better.

[@heatheldridge7127]

I’m right handed and can’t get my head around blade right saws. Wish I could - almost every brand makes its best saws with blade right...

I know what you mean. Ryobi, oddly enough, is the only manufacturer that I have seen make a sidewinder with it's blade on the left side. I think that blade left is considered a DIY style, but worm-drives have historically had the blade on the left so it really doesn't make a lot of sense.
