DEWALT 20V MAX Circular Saw Cordless, Battery Not Included (DCS391B)

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!!!

I’m slowly transitioning my hand tools to cordless and this was the latest one, so convenient! I bought it as tool only. It’s lightweight, has cut everything I’ve put to it up to 2x8, has the standard 45 angle ability and as others have said the immediate stop on blade rotation is a great feature. So far nothing but positives.

I really like this saw and rechargeable system. Is it possible to love a saw? I have several tools that use the 20-volt batteries, including the 20-volt rotary hammer and 3 different chargers, as well as the 12-volt vehicle charger so I can recharge the compatible hand-held flashlight and flood light for road emergencies or anywhere I need to see in the dark. I carry them wherever I drive. One never knows. As with any saw, using a sharp blade appropriate for the material one is cutting is always the most important measure to ensure top performance. I have this saw paired with the premium 5Ah & 4Ah batteries and a selection of blades for different materials, some Dewalts and some Diablos (my favorite blades). It fully exceeds my expectations. It will cut all day and then some. It's light and extremely portable, and it tears through solid oak and maple like it's going through soft butter. There is a small "learning curve," as one becomes comfortable with the saw blade on the left side of the tool, as viewed from the operator's perspective. The corded saws I've always used have the blade on the right side, but it doesn't take long to adapt to this configuration. Without a doubt, this saw is my favorite power tool followed by the rotary hammer, which is a close second. The only (small) source of disappointment is that it's shipped without a rip fence. For the life of me, this seems rather cheap behavior on the part of DeWalt, a manufacturer of quality tools that usually doesn't cut corners in my experience. My guess is that it would probably only have cost DeWalt a few extra pennies to have included the rip fence with the tool rather than inconvenience customers with the necessity of purchasing it separately upon discovering this admittedly minor deficiency. The rip fence is available on Amazon for about thirteen dollars as I write, so that issue can be readily addressed. It seems odd, though, and the discovery of the absence of a rip fence in the package might lower the perception of value for some customers. With shipping charges and sales tax, it could easily add $15-20 to the total cost of the saw. Of course, if one does not intend to rip, one might elect to skip it, but that could be short-sighted. From my perspective, one never knows if the rip fence might be needed in the future and there could come a time when it may not be as readily available, so my choice was to make the purchase so as to have it on hand for any contingency. I'm so pleased with this saw that I'm thinking of purchasing the Dewalt 36-volt cordless saw as well. The 36-volt tool uses full-sized 7¼ blades and has even more power than the 20-volt model, thus allowing one to cut thicker material, likely with even greater battery charge longevity, but I digress. To be clear, the reviewed model (20-volt) will meet the needs of the vast majority of those looking for a well-performing portable saw without the encumbrances presented by a cord and its not as heavy as the 36-volt model. I think there's some good news if I decide to purchase the larger model as well in that the rip fence appears to be interchangeable between the two saws, so that assuages the issue from my perspective. Anything I would add would be all good, however it should be obvious that I'm pleased to have made the purchase of this quality DeWalt product.

This 6.5-inch circular saw works great. I read some complaints about battery life, but after years of using DeWalt and Milwaukee battery tools, I found the battery life of this saw to be just what I expected. You don't approach a job with just one battery and expect it to go a long time; you always plan for a spare(s) and for recharging. It was easy to use, easy to see the guide marks and didn't blow sawdust up at me. Any circular saw can bind, and you just need to get familiar with the saw, the material you're cutting and back off on how hard you push.

for the longest time i wanted a cordless circular saw. now this thing does the job. before switching to the de walt 20v line i had plenty of the craftsman 19.2 tools including the saw. i mean these are/were toys. you really come to realize it once you start to work with this dewalt gear. for this dewalt saw i bought the craftsman 40teeth i think its the 6.25 inch blade.(since it came without a blade) a good,sharp blade is key on working with these cordless tool. to compare it with a brand new fully charged 19.2 battery pack and supplied blade i did with the craftsman saw 7' on a 3/4 ply......then the battery was flat. the dewalt with the 40t blade and a 3.0 amp new and fully charged battery.: -24' through pressure treated T1-11 5/8" (all teh wood was pressure treated) -8' 3/4 flooring ply -9' 2x4 rip cut and plenty of 2x4 cross cuts. the key was a brand new blade. it is clearly less with a dulled up blade. just to have this freedom not to hang on a cord is priceless. it gives you accurate cuts (with exception -read below) so for a lot of my framing work to cut 2x4, i'm using this saw with a "squangle" even to cut 4x headers or posts. it is amazing. now the two reasons why only four stars is simple. if you are left handed you may be the happiest person on the planet with this saw. it is not build for right handed. so if you cut off 1/2 inch the weight of the saw is not resting on the 2x4. these cuts are not accurate and more of a drag.( try cut overhangs...no good) frankly i think what must have happened is when they build the saw they must have flipped the blueprints by accident- or it was a purely academical engineer that never smelled a job site. and the other reason is the shoe. they have two different type of shoes for this saw. the metal one (on my saw) even i kept it always dry the coating came/comes off on the edges and it started and is still rusting. i noticed this on some of the other de walt tools that screws and the metal parts that are black if they get wet and not dried the start to rust. what i'm doing to prevent i wipe 'em with a oily rag (damp not soaked)

Light, powerful, and very decent battery life! I bought this for a nonprofit I was working with in Panama. We operated out of a field station in the jungle that ran on a little 1000w hydroelectric plant. Most of the wood we were cutting was tropical hardwood. This little saw got further with that than I ever expected it would. Here are my rough estimates: * Casual project: A+. It's such a blessing to be able to just pick it up off the shelf, take a foot off of a board and put it back. I can't tell you how elated I was to be able to do this. * Day project: A+. I used it a number of times all day long for lightweight hobby-type projects (changing batteries a few times, of course, though not as much as you would think). * Limited professional job: A-. Don't let the minus fool you -- that's still an A! It's just kind of annoying to have to change batteries if you're using it tons. * Heavy professional job: C. Unfortunately, it heats up quite a bit under heavy use, and once it heats up, it shuts itself off. There's no solution for this other than just waiting around for it to cool down. I'm glad that it has the shutoff circuit, but this means it's never going to be a replacement for your plug-in circular saw. That said, it'll cut just about whatever you throw at it, so it's still worth its salt in a pinch. As for notes on cuts, I'm afraid it's been too long since I used it to have good solid numbers. I do want to point out, though, that I used it with some really hard tropical woods (Nispero, cuajao, mahagony...) and have two relatively reliable figures in my head for them: * Doing small cross cuts (like cutting 2x4s and 2x6s to length) I could go just about forever as long as I kept changing batteries (the batteries lasted about 15 minutes under heavy use in these cases). * Ripping boards was very difficult. I could usually get about 10 to 12 feet in 2" - 3" hardwoods before the saw overheated and stopped. Then I had to just let it rest and pick up again when it was cool.

So far so good. Works like a champ.

For years, I've resisted buying a cordless circular saw based on my experience with one 20 years ago, when they first came out. The old Makita system just didn't have the balls to last long enough for professional use. How times have changed.... I'm a part time home improvement carpenter, and have had my Dewalt 20vMAX cordless for about a month. I purchased the "Tool only" version, and added 2 of the new 5amp hour batteries to go with it. I went with "tool only" based on some reading here that the tools included in many combo deals are not the same as buying the tool only, and I know for sure that is true with this saw. I have used this on a few framing jobs, and mostly on interior trim work, cutting lots of 1x pine moulding and 5/4 pine too. We did a job with all PVC Azack trim, and it cuts that stuff like butter. Just today, I had to rip 16' of 1x6, and this saw never even slowed down. At the end of the job, I checked the battery life and it still showed full. This saw is nice and lightweight compared to a standard plug in 71/2" saw. Obviously, it won't cut as deep, but it easily cuts through 2x4. I would guess you could crosscut 100 2x4 studs or more before needing to swap batteries. It easily cuts 3/4" CDX plywood too. I find this saw very well balanced in my hand, and cutting a straight line is effortless. Working on a ladder is also much easier as it is lightweight compared to a full circular saw. Overall, I am very impressed with this, and it's now my go-to circular saw for most jobs. So much easier than stretching out a cord. NOTE: the blade supplied with the saw isn't very good, so get the Diablo http://www.amazon.com/gp/product/B00008WQ2P/ref=oh_aui_detailpage_o08_s00?ie=UTF8&psc=1 to put on. PROS: lightweight and great balance for cutting Powerful enough to cut wet 2x4 fir studs Long lasting with 5AH batteries Well placed angle and depth adjustment locks Very accurate notch to show the left side of the blade All around sturdy and quality built CONS: Blade is on the left of motor (like a worm drive), might bother some people A secondary lockout button that must be pushed before you can pull the trigger; didn't bother me but bugs the hell out of my brother Tool only means just that: they don't even include the rip guide I wouldn't break this saw out in the morning when starting to frame an entire house or roof, but for paneling, small framing, moulding and plywood, this is a great option.

Works well

Bought this light saw for use at our cabin. It was on promotion and the price was great. Upon receipt one of the teeth on the included blade simply popped off. It was still wrapped in the plastic! I called Amazon and they said it’s the manufacturer’s problem. The saw wind have still cut, I was most concerned about a safety issue should other tips fail while I was actually trying to cut something. I called Dewalt and they facilitated the replacement immediately of both saw and blade. Further, a couple weeks later received another blade at no cost for my inconvenience. The unit functions as expected for light weight and duty. It is an exceptional value and the company support continues to make look to Dewalt when I need power tools. FYI, for all Dewalt (and top brands) they carry a 30 day retailer warranty that Amazon makes very difficult to use… always pointing customers to the manufacturer. If you’ve received a faulty tool, insist that Amazon provide the replacement as per their agreements with the manufacturer!

Perfecto

Serra muito boa
