Saw Perfection !

Reviewed in the United States on October 19, 2017

Style: 20V Brushless 7-1/4"" (Tool Only)Pattern Name: SawVerified Purchase

This is the finest circular saw I have owned and I have owned many. I have waited for some time for a full sized, full featured right-blade 7-1/4" sidewinder. I am a fully seasoned former carpenter and I have always personally preferred B&D Sawcats, the very similar DeWalt models, Makitas and the better grade Skils. I have other cordless saws in various sizes which with the exception of a small 12v Makita are all left-blade saws. I consider them preferable only for cutting sheetgoods. I have 2 Skil wormdrives which I have used a bit when framing using West Coast methods. Most of my work was done with East Coast methods and therefore using right-blade sidewinders such as this. This saw has the fastest rotational speed I have used and that is perfect with modern thin kerf blades. This saw arrived perfectly aligned and adjusted. I particularly like the instantaneous blade brake, the led light which illuminates the line of cut exceedingly well, the balance and, of course, the lack of a cord. I remember many hours of frustration fighting cords in my time. I remember several near accidents using old saws without brakes. I would have loved to have had such a saw as this 15 to 50 years ago. One note; The pictured saw shows no rafter hook. The one I received has an excellent flip-out rafter hook. Icing on the cake! ......What a terrific saw!

works good.

Style: 20V 6-1/2" Saw (Tool Only)Pattern Name: SawVerified Purchase

got tired of running extension cords for my skill saw. so figured it was time to add another dewalt 20 volt tool to my inventory. didn't notice till after i purchased it was a 6.5" saw but still does the job. And blades are about 25-30% cheaper for the 6.5" then the 7 1/4". Used to cut 2x4's, osb and sawed 2x6's and cut them all without a issue.

Would recommend not leaving battery in unit. Safety switch works but would be easy to accidently hit safety switch and on switch while carrying it. so i always carry unit without battery and put battery in when i use it.

Great Saw for Everyday Use

Reviewed in the United States on April 7, 2019

Style: 20V 6-1/2" Saw (Tool Only)Pattern Name: SawVerified Purchase

I like that this saw is lightweight and easy to use. High quality and I like that the brake stops instantly when the trigger is released. Has depth adjustability with measurement gauge and 45 degree angle. It is easy to use and great for cutting sub-floor, stringers, 2x4's and much more. I have had no issues with not being able to keep up with the tasks I've subjected it to.

The reason I bought this one is because almost all of the DeWalt power tool package kits I was looking at buying all had "left-handed" circular saws I didn't want and DeWalt flashlights I didn't need. So I didn't buy the kit. I bought the "right-hand" saw I wanted and bought the other power tools I wanted that were in the kit individually. Also the kits only came with two 2.0AH batteries that I didn't feel would keep up with heavy use of a saw like this. So I bought the DeWalt 60V reciprocating saw kit that had two 6.0AH batteries that would be better suited for this circular saw. It was only slightly more expensive to get the tools I wanted individually, but got what I wanted and the batteries I preferred.

This saw was purchased tool only. The battery in the picture was purchased separately.

Really like this saw and would buy it again.

Perfect Saw For DIY

Reviewed in the United States on December 13, 2017

Style: 20V Brushless 7-1/4"" (Tool Only)Pattern Name: SawVerified Purchase

I have framed my whole basement and garage with this saw and dewalt driver / hammer drill combo. It is the perfect saw for me. It cuts fast, lasts surprisingly very long even on the 2amp battery. The best feature is the way they designed the bottom plate you can see EXACTLY where your blade is cutting. I make perfect cuts with this every time. It is also pretty quiet compared to a plug in saw. I cut 2x4 all night in the basement while people slept upstairs. This is the only saw I will ever need for house projects.

Great kit, but buy a big battery in addition

Reviewed in the United States on August 30, 2018

Style: 20V 6-1/2" Saw (Tool Only)Pattern Name: SawVerified Purchase

Excellent kit. Batteries are underpowered for anything but the normal drill. They operate the equipment fine but you are only going to get a about 15-20 cuts on a 2x4 with the regular battery. With two batteries you may be okay if your not cutting a lot fast but I built a shed and wished I would have bought a 5 or 6 amp hour battery earlier. I spent the first two days spending most of my time trying to figure out what I could do while batteries were charging then prime came through with the big battery and I was pretty solid the rest of the project.

Pleasantly surprised by this cordless saw

Reviewed in the United States on April 11, 2019

Style: 20V Brushless 7-1/4"" (Tool Only)Pattern Name: SawVerified Purchase

We needed a saw that we could move around in and outside our shop to cut wooden crates open. This saw fit the bill. We paired it with Dewalt's DCB205-2 20V MAX XR 5.0Ah Lithium Ion Battery. They do a fair job of keeping up with the saw. We also use it to trim pallets down to custom sizes or cut lumber to make larger pallets when necessary.

I liked it so much I bought one for use personally and used it to cut the tops off 50 pressure treated 4x4's for a fence. Managed that on one 5.0 Ah battery. Was adjusted to 22.5 degrees and set at deepest cut depth. No problems. Was even used to rip a 45 degree angle at the edge of 2 of the 4x4's. Only time it bogged down was when I didn't have the blade very straight on a plunge cut (I know, this saw isn't meant for plunge cuts).

Very nice saw, just needs a better blade.

Reviewed in the United States on January 7, 2019

Style: 20V Brushless 7-1/4"" (Tool Only)Pattern Name: SawVerified Purchase

I like the saw. I bought the bare tool, since I already had several batteries. The bare tool does not come with a rip fence, that will be anothe 15 dollar, sold separately. The blade supplied with the saw may be fine for rough home construction carpentry work, but if you are into more finished work, count on another 15 dollars for a blade. I bought this saw primarily for projects using pressure treated lumber, and with a 5Ah battery it will put in a full day for me. There is plenty of torque, and the almost instantaneous blade brake is a really nice feature. And no extansion cord to drag around the shop or job site, or a generator to set up.

Only negative ... cheapskates never included allen and wrench for blade changing

Reviewed in Canada on September 21, 2018

Style: 20V 6-1/2" Saw (Tool Only)Pattern Name: SawVerified Purchase

This has a very good feel in the hand ... very light and comfortable ... tried it out right away on a few 2x4's ... cut quickly and actually very quietly compared to my Skil saw. Purchased for 95 bucks in the warehouse deals but honestly it arrived in original packaging and never opened. I've been buying these Waitley 5.0mah and 6.0mah batteries for half of the dewalt ones so I bought the baretool. For the cost of a cheap little allen and wrench set to change out the blade you'd think Dewalt would add them with the tool. For a couple bucks it would save me taking mine from my set of allens and wrenches everytime I go somewhere. Taking a star off for that just because I can.

This saw could have easily incorporated an Allen key storage on the base plate ...

Reviewed in Canada on November 29, 2017

Style: 20V 6-1/2" Saw (Tool Only)Pattern Name: SawVerified Purchase

Exceeded my expectations as far as performance. I thought the saw (especially with the included 16 tooth blade) would have bogged down much more being cordless. It powered through 3/4" plywood, hardwood skids (slats and thick supports) and chewed 2x4's for breakfast. Was initially worried if there was enough blade to cut 4x4's being 6 1/2" but, it's more than capable with about 2" of cutting depth.
*******The major down fall is that there is NO included wrench/Allen key to change out saw blades. It's advertised as bare tool (without battery) but I had no idea how bare it was. This saw could have easily incorporated an Allen key storage on the base plate for example and included the tool for efficient blade changes

know the limits of a cheap non-brushless circular saw

Reviewed in Canada on October 26, 2019

Style: 20V 6-1/2" Saw (Tool Only)Pattern Name: SawVerified Purchase

This saw is designed for a low sales price, not to be a great tool. It cuts well for small cutting demands around the house. It does not feature a brushless motor which you will be reminded of with every single cut and plenty of battery swaps. The does not perform well on 1.5Ah or 2Ah batteries, you need the larger onces with 10 or more cells (can deliver higher current). Is it worth the money if you need a couple of cuts a year in a home enviromnent: YES. Would I buy it again for a larger project, definitely NO. It is just too flimsy and lacks the power of a conventional or a brushless driven saw.

DEWALT 20V CIRCULAR SAW IS TOP NOTCH .

Reviewed in Canada on January 18, 2018

Style: 20V 6-1/2" Saw (Tool Only)Pattern Name: SawVerified Purchase

The 20v vs the 18v is like night and day . Both saws are built rock solid and have used them both . I prefer the 20v as it does all I require as a do-it yourselfer . I have no qualms recommending the saw and I have never had a malfunction. I use it up at my off grid camp and no more genset to operate. A win win for me. Cheers

Works great and love the fact that I don't need an extension cord.

Reviewed in Canada on January 26, 2019

Style: 20V Brushless 7-1/4"" (Tool Only)Pattern Name: SawVerified Purchase

I have been very pleased with this Dewalt saw. It is better than another smaller bladed and cheaper cordless saw, a lot better. It is not as powerful as a corded saw but quite close and does a great job of cutting through wood. I really dislike extension cords and cords that get in the way in general. One can glide through plywood with having the cord catch as you work through it. Set up time is a fraction of the time and you can take it anywhere on a large property without having to bother with a generator. I bought this one for its brushless motor and the standard 7 1/4 " blade. This came as a bare tool (no battery) with one blade.
