but highly recommended for DeWalt battery users!

The DEWALT DCS391B is a powerful and reliable 20V MAX circular saw. The 6-1/2-inch blade cuts smoothly through wood, and the 460 MWO motor delivers excellent performance. The 0-50° bevel adjustment is precise, making angled cuts easy. Lightweight yet durable, it's perfect for DIYers and pros. Bare tool only, but highly recommended for DeWalt battery users!

With the right blades, this is a honey of a saw.

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.

Great DIY, saw, bought it for works around the home. Not as powerful as the XR, but this gets the work done.

Got it on sale for a steal! Great saw!

Great circular saw and I snagged it on a great sale (almost 30% off!). All of my battery operated tools are exclusively Dewalt (with one exception) so I love the flexibility of one battery system for all of them.Just received so have not had a chance to put it fully through the paces, but I expect nothing but good things.
