    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 2×4’s, osb and sawed 2×6’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.

    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, 2×4’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.

    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 2×4 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.

    I simply adore this saw. I install real estate signs as side job and I have always used a hand saw when I need to cut wood while on the road (which is about once or twice a week). I didn’t realize how significantly batteries have improved over the years and was embarrassed when I realized how much simpler this made my job. This saw is powerful and will go a long way on a single battery. I have been finding tons of uses for it and have used it a few dozen times since I purchased it. I was so impressed that I’ve been buying other Dewalt battery tools and love all of them. I’ve had the same 18V Dewalt drill for at least the last 15 years and it is running like a champ. I hope to get many years of use out of this. It has paid for itself already.

    This skill saw is a great addition to DeWalts 20V Max line of tools.My first reaction after using this skill saw for a while, was just WOW, this thing is Amazing!!!The motor they use is smooth as silk, and powerful.I was hoping to wait till DeWalt incorporated there brushless motor into this skill saw.But I needed it, so I bought it. Man am I happy I did, I really LOVE this skill saw!This is a superb saw!It has all of the features and power of a Top Quality corded skill saw, and it’s light weight, with the 4Ah & 5Ah batteries, it does the work of a heavy duty skill saw.I’ve been in construction since 1980, and have used most all light and heavy duty power tools. This Skill Saw ranks among the best I’ve used, in cordless saws.Just remember your blade choice is the most important factor in how effective this saw will perform. Please see my blade recommendation below.Others have commented on it’s longevity with there batteries (1.5Ah & 2Ah batteries), regarding they drain fast. The smaller DeWalt batteries are going to drain faster. This skill saw is powerful, and puts a heavy load on the batteries. With this saw, you need the High Capacity 4Ah &5Ah batteries (model 204 &205). This saw will work with any and all of DeWalts 20V Max batteries, but the lower capacity batteries aren’t recommended.I only use DeWalts 4.0Ah and 5.0Ah batteries, and with those, I can use this skill saw all day long, with 1 battery lasting most of the day, and usually all of the day.Features:-This skill saw has a blade break, which is a very nice feature in any skill saw. As soon as you release the trigger, the break engages, and stops the blade from spinning within seconds.-This skill saw also directs the cut material away from the user, and away from your line of sight.-This skill saw has the ability to cut from a directly perpendicular (90 degrees), and also can cut up to a 50 degree angle.-This is a nice light weight skill saw, and that greatly cuts the fatigue you would feel from using a traditional skill saw, all day long.-This skill saw allows for a direct line of sight to the blade and working surface. This is much like the design of a worm drive saw (a Roofers Saw), the design of most all other skill saws have the motor and the blade on opposite sides, so the skill saw operator would need to look over the top of the saw, to see his work surface. This is Not the case with this DeWalt Skill Saw!-The front and the main handle has a rubber over mold, and this gives the operator a great and comfortable grip on the skill saw. This makes it safer, and easier to control.Blade choice is important!-This skill saw uses a standard 5/8ths inch arbor, which gives the owner a wide selection of blade choices.There is a LOT of new blades out today that use think kerf cuts. This means the width of the cut is very thin, usually about 1/16th of an inch thick. Just know that these are basically cheap, and throw away blades.You also need to know, the thinner the tooth, the faster it will dull.-Please see Blade recommendation below-This blade here: Vermont American 6-1/2-Inch 40T Smooth Cut Carbide Teeth Circular Saw Blade, is one of the best blades you can buy for this saw. It’s an extremely high quality blade, and the same blades that I use professionally, every day. It can be resharpened many times before needing replacement. It’s very sharp, and uses very high quality carbide teeth.I Very Highly recommend this saw blade!To end, this DeWalt skill saw is a Professional Quality skill saw, and will last you for many many years.Everything about this skill saw is very high quality, and built very well.Very Highly Recommended!!!

    This has a very good feel in the hand … very light and comfortable … tried it out right away on a few 2×4’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.

    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 2×4’s for breakfast. Was initially worried if there was enough blade to cut 4×4’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

    Dewalt being Dewalt! I’d but nothing butI did not think this little saw would have the power to cut a 2×4 but it just whizzed through it like a hot knife through butter.Hex key is needed to change the blade. There is no blade lock which is rather awkward when changing blades. This is my only peeve

     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

    I took it out of the box,put a 5 ah battery in it and away i went. Cut 1×4″s 2×4’s,and 2×6″s some 8 to 10 foot lenths in one foot pieces for about ten or more minutes straight with no battery drain.I think it worked well.

  11. Amazon Customer

    I bought this item about 9 months ago and only used it three very short times. I found it extremely cumbersome. Now as I look at pictures again on here I see they sent me the wrong item. The one they sent me the blade is on the right side of the handle. In the picture the blade is on the left side where I need it to be. There is no way to change the blade. I noticed a similar one where the blade is supposed to be on the right side. I believe they sent me that one in error. I am not a skilled craftsman to know the difference right away as I only needed it for craft items. I can not find a way to contact the buyer. But it’s probably too late anyway.

    I had an old Ryobi set, that the only thing that kept me from getting rid of it, was the cordless Circular saw. A couple of years ago, I bought a 20v Dewalt drill and driver set, and waited patiently for the this saw to go on sale to complete my set. When the price dropped to $89 on Amazon, it was a no brainer instant buy for me. I love the feel of this saw and the power. Easy to use, convenient with no cords to get in the way.

    Great tool, light enough to be used with one hand if needed (although not recommended).Having the key for the blades inserted in the handle is just a genius idea! It works very well with different types of cuts, from standard framing to melamine panels (using a 90 theet blade for that one). A 4 Ah battery will usually last for a day of medium use. The shoe is also quite versatile and supports most angles.I would recommend getting the 40 teeth “precision” blade for this saw, it doesn’t noticeably slows it and make much cleaner cuts.

    We were looking for a secondary saw to our Rigid 7.25″ and compared several brands before picking this one.This 6.5″ Dewalt is extremely light compared to most 7.25″ saws. In fact, our Rigid 7.25″ weighs about twice as much. It was a night-and-day difference in ease of control, get better quality cuts, and more pieces done before our hands got tired. The closest competitor was the Milwaukee 6.5″ M18 – virtually the same weight but with an 80% higher price tag at the time.This model also has a “brake” that stops the blade from spinning almost immediately after letting go of the trigger. Beginner DIY’ers will appreciate this safety feature that wasn’t in our older Rigid and also isn’t in some of the cheaper brands.The one drawback for a few people will be the smaller 6.5″ blade may not cut through thicker pieces in one pass – you’ll need to flip the wood over and do a second pass. That’s a small issue consider 99% of what we (and probably most people) cut are 2×4’s, 2×6’s, or plywood that’s 1″ or less, which this saw cuts with ease.If you’re not already invested in another brand of batteries or don’t mind adding another one, this Dewalt is an excellent saw – lightweight, low price for this level of quality, and a brand the pro’s know. Don’t make the same mistake of buying cheaper brands to save a few bucks – you’ll end up replacing them quickly and wasting your money. This one will probably last forever or until they stop making batteries for it.

  15. The great canadian

    Its 5,250rpm motor makes quick work of most household or job site cuts. With a 6 ¼” blade and 2 ¼” cutting depth, it offers a superb combination of power and versatility, plus the 5/8” arbor means you have access to a huge variety of blades. Compatible with the fleet of DeWalt batteries it can last all day(with multiple batteries changed all the time haha), and since it only weighs 7 lbs., you won’t wear out either. It handles bevel cuts up to 50 degrees, comes with a basic carbide-tipped blade, and features a blade brake.ProsHigh-performance cuttingBattery interchangeable with other DeWalt toolsComfortable and lightweight so you can saw all dayBlade brakeConsBattery hungry
