In this video I put the DEWALT 20V MAX 12” cordless chainsaw (DCCS621) through a real-world test and compare it to the older DCCS620. I walk through the unboxing, the key features, and what DEWALT actually changed on this newer model—then I get straight to cutting so you can see what it does in the kind of yard cleanup and firewood situations most people actually use a small saw for. My main focus here is whether this compact 12-inch saw is “enough” power without the hassle of gas. I run it on logs and branches, and I also push it past what you’d normally do by cutting material bigger than the bar to see how it behaves when you’re asking a lot from a small cordless chainsaw. If you’re already on the DEWALT 20V platform and you want something lightweight, quick to grab, and way quieter than a gas saw, this is the kind of tool that makes sense—especially for cleanup, trimming, and smaller firewood jobs.
