The Worx 40V Power Share 12” Cordless Chainsaw with Auto-Tension is the tool for you when you want gas-like performance without all the fuss of gasoline, and still want to be free from the cord. With a 21 ft/s cutting speed and 3/8” chain pitch, you get performance that is as good or better than light-duty gas-powered saws. Plus, they’re much easier to start, much cheaper to maintain, and you won’t fill the neighborhood with fumes. And with an electric, you might get tangled up in the cord, and you’re always tethered to an outlet. With the 12” bar, you can safely cut fallen trees up to 21” in diameter. The automatic chain tensioning and lubrication systems make this saw easier to maintain and keep it running at peak efficiency. And the included bar and chain sheath protect the tool while in storage. This particular model doesn’t come with batteries, but that’s by design. It’s meant for users already on the Power Share platform, who can just grab two batteries from the collection they already have. It’s the cost-effective way to buy new cordless tools, because you don’t have to buy a battery each time. The Worx 40V Power Share 12” Cordless Chainsaw with Auto-Tension may be compact, but it’s packed with power. That slim design means it’s easier to control. And the two 20V batteries it uses gives it enough juice to tackle all your routine backyard maintenance, like cleaning up fallen trees and limbs after a storm.
