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.

Love it. Have a few Dewalt items. Used a friends saw & had to have one!! This was very affordable. The Price and size was perfect. This cuts 2x4 with ease. Easy & portable & cuts smoothly. The unit- as all of them pulls a lot of power so the battery does not have a long life-- FYI.. But long enough to do the project. Just keep another handy. Good product-- good price

Love the versatility of being cordless. Have used the saw many times that I would've pulled my corded saw for. Cuts good. It's taken a beating in my truck and 4 wheeler with no issues.

The DeWalt DCS391B is a popular choice for contractors and DIY enthusiasts looking for a cordless circular saw that balances power, portability, and affordability. This "bare tool" version means it doesn't include a battery or charger, making it a great option for those already invested in the DeWalt 20V MAX battery system. Here's a breakdown: Pros: Good Power for Cordless: While it won't replace a corded saw for heavy-duty ripping all day long, the DCS391B offers impressive cutting power for most common tasks. It can handle 2x4s, plywood, and even thicker lumber with relative ease. Lightweight and Maneuverable: Compared to corded circular saws, and even some other cordless models, the DCS391B is relatively lightweight and easy to handle. This makes it less fatiguing to use for extended periods and more convenient for working in tight spaces or overhead. Durable Construction: DeWalt is known for its robust tools, and the DCS391B is no exception. It feels solid and well-built, suggesting it can withstand the rigors of job site use. Bevel Capacity: The saw can bevel up to 50 degrees, providing versatility for a variety of cuts. The bevel adjustment is relatively straightforward and secure. Blade Brake: A blade brake is a valuable safety feature that quickly stops the blade rotation after the trigger is released. This helps prevent accidental cuts and makes the saw safer to use. Compatibility with 20V MAX Platform: A major advantage of this tool is its compatibility with DeWalt's extensive 20V MAX battery system. If you already own DeWalt 20V MAX batteries and chargers, this is a cost-effective way to add a circular saw to your arsenal. Easy Blade Changes: The spindle lock makes blade changes quick and easy, minimizing downtime. Cons: Battery and Charger Not Included: As a "bare tool," the DCS391B doesn't come with a battery or charger. This is only a con if you don't already own DeWalt 20V MAX batteries. If you need to purchase these separately, it significantly increases the overall cost. Runtime Depends on Battery Size: The runtime you get will depend heavily on the amp-hour (Ah) rating of the battery you use. A smaller battery (e.g., 2.0Ah) will provide less runtime than a larger battery (e.g., 5.0Ah or higher). For demanding tasks, you'll want to invest in larger batteries. Not Ideal for Thick, Dense Materials: While it can handle most common lumber, the DCS391B might struggle with very thick, dense hardwood or treated lumber, especially for extended cuts. A corded saw is generally better suited for these applications. No LED Work Light: The lack of an integrated LED work light is a minor drawback, as it can make it more difficult to see the cut line in dimly lit areas. Dust Collection: Dust collection is minimal. Consider using a dust mask and eye protection. Who is it For? The DeWalt DCS391B is a great choice for: DIYers: Homeowners who need a reliable circular saw for occasional projects around the house. Contractors: Professionals who need a lightweight, portable circular saw for punch-list items, trim work, and general tasks. Existing DeWalt 20V MAX Users: Anyone who already owns DeWalt 20V MAX batteries and chargers and wants to expand their cordless tool collection. Overall: The DeWalt DCS391B is a solid, reliable cordless circular saw that offers a good balance of power, portability, and durability. While it has some limitations compared to corded models, its cordless convenience and compatibility with the DeWalt 20V MAX platform make it a worthwhile investment for many users. Just be sure to factor in the cost of a battery and charger if you don't already own them.

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.
