    • 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

    • Truly outstanding little saw.
Color: Yellow Size: 6-1/2 inches
I absolutely love this saw. It's small enough and light enough that it's perfect for most any job. And it uses my standard DeWalt 20-volt batteries. This is probably not for the commercial contractors who will likely want a larger, more powerful saw. But for the average DIY person, this saw is great. And it's a DeWalt, so you know it's outstanding quality. ... show more

    • Buy this excellent 👍 saw, you won't regret it
Color: Yellow Size: 6-1/2 inches
DeWalt saw is a excellent saw. It saws like cutting butter, very smooth. The quality and build of it is excellent 👍. I have a DeWalt drill, charger and batteries, all 3 are top notch 5 Stars, never had a problem with any of them. I beat the hell out the drill and it keeps going, just can't kill it .

    • 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
