  • With the right blades, this is a honey of a saw.
Color: Yellow Size: 6-1/2 inches
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. ... show more

  • DEWALT Chainsaw Review: Powerful, Reliable, and Surprisingly Lightweight
Color: Yellow Size: 6-1/2 inches
I’ve been using the DEWALT chainsaw for a few months now, and it’s exceeded my expectations in every way. Whether you're trimming branches or cutting down small trees, this tool delivers serious power with the reliability you'd expect from DEWALT. One of the best features is how easy it is to use, even for someone who isn’t a professional. It starts up quickly, and the controls are intuitive and well-placed. The chainsaw is also much lighter than I expected, which makes it easy to handle and reduces fatigue during longer jobs. I’m especially impressed with the battery performance (on the cordless model). It holds a charge well and provides enough runtime to get through most jobs without needing to stop and recharge. Maintenance is minimal—chain tensioning is tool-free and straightforward, and the bar oil reservoir is easy to fill. The build quality is solid, and it feels durable and well-balanced in hand. Whether you're a homeowner handling yard work or someone who needs a dependable tool for more frequent use, the DEWALT chainsaw is a great investment. ... show more

  • Works great, requires dexterity to pull the the trigger switch
Color: Yellow Size: 6-1/2 inches
A nice saw. I already had DeWalt battery powered tools, so this was a no-brainer. My only hesitation in giving the fifth star is because I find that the combination of pressing the trigger switch lock-off button and pulling the trigger switch to turn the motor on rather awkward; I’m hoping that with use it’ll become more automatic. ... show more

  • Profesional Quality Skill Saw!!! (At a Great Price)
Color: Yellow Size: 6-1/2 inches
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!!! ... show more
