Rated 4 out of 5 by from 1/2 the weight but not 1/2 the power Bought this to pare up with my other 20V tools. And to replace my 30+ year old Milwaki Hand Saw. I liked the fact that the fence on this is on the left and being right handed... it is much easier to see the blade line. It has no laser which you can't see in any light anyway so that makes no difference. The smaller blade makes no difference as well... I only cut 2x4's and plywood. You do need the 4.0 Ah battery to get any kind of life out of it. I only have 1.5 and 2.0 Ah batteries and yet it performed very well. I wish it had a fence extension on it but that is minor. The blade is good... the weight is great... it cuts through2x4's and 3/4" ply like butter (you just can't force it too much). Great build...

Rated 4 out of 5 by from Great saw, though w/ minor improvement needed Saw performed really well in helping to reclaim some oak flooring in my Victorian home. Light, handles and cuts well, with no cord to worry about and efficient battery usage. Only concerns are the plastic saw guard and the lack of easy-to-read measurements on the shoe.

Rated 5 out of 5 by from Awesome tool I bought this Saw last week and immediately undertook demolition of a 760 sq ft deck. The project took approx 5 hours (of course the saw wasn’t running the entire time) cutting over 200 5/4ths pressure treated deck boards and over twelve 2” x 6” joists all on one charge and it could have kept cutting. With the new blade it cut through this aged lumber like a hot knife through butter. Both my son-in-law (my informal foreman) and I were so Impressed with this Dewalt corldless saw with the 20v 5ah battery that he is getting one as well. I have owned a Dewalt cordless drill and an impact driver for 4 years and they perform equally well. Very well built products......the reciprocating saw is next.

Rated 4 out of 5 by from Light and powerful Will cut through pine like butter and some very hardwood (little more time) Excellent saw, have it for a year now, second circular saw, and for the control, the brake system and the level of confidence it gives me, that's my go to saw. Only bad thing is the guide on the base that should be an arrow to guide you on the line and instead you kind of have to hide the line, kind of confusing untill you get used to it

Rated 1 out of 5 by from Didn't buy it for lack of available blades I was about to buy it since I already use cordless DeWalt tools but realized last minute that it is virtually impossible to find 6.5" blades with 40, 60 or 80 teeth. I guess this is the perfect tool to cur 2x4 for framing, but not for fine finishing. Too bad.

Rated 5 out of 5 by from Powerful saw and very versatile! This skill saw is the perfect go to for everyday jobs such as a framing or basic cuts. It’s lightweight, powerful and the batteries last quite long. I recommend using the 5 amp battery to prevent overheating and to add longevity.

Rated 4 out of 5 by from Great, but you'll need to get a better battery As I did, you will probably be thinking "I have a Dewalt drill/impact with batteries, so I can get this and reuse the same batteries". Yes, it will work BUT it really won't last long. Drill batteries seem to be about 1.3Ah, Dewalt sells the saw with a 5.0Ah battery. So if you have to do 'real work' where a powercord doesn't reach. You will need to get a bigger/better battery.

Rated 4 out of 5 by from Good tool Good tool that does its job. Given the price, no complaints, but you should be aware this isnt a brushless tool. So it's great for smaller jobs, but if you're using to build a deck or to rip a lot of pieces, it's better to go with the more expensive brushless model.

I use a Dewalt 20v MAX drill that has the DCB207 20v 1.3Ah Battery and a DCB107 charger. Will these batteries work with the DEWALT 20V 6-1/2-inch MAX Lithium-Ion Cordless Circular Saw Model # DCS391B?

Asked by: WalterG
Yes it will work. You must know than more powerfull batteries are normally proposed with this tool, so maybe your battery will discharge sooner... But depending of your situation it could be ok if you don't anticipate to use intensively
