The DEWALT DCCS677Z1 60V MAX 20 in. Brushless Cordless Chainsaw Kit is a professional-grade battery chainsaw built for demanding outdoor cutting. This is a chainsaw designed for felling, bucking, storm cleanup, and cutting thick wood without the upkeep of a gas engine. Model Number: DCCS677Z1. If you want a cordless chainsaw that can step into real work instead of occasional yard duty, this is the one DEWALT aimed at.

The big story here is output. DEWALT rates this saw at up to 4 peak horsepower when paired with the included DCB615 FLEXVOLT battery, and claims 20% more peak power than a 50.2 cc gas chainsaw along with up to 2.36X the torque. On the job, that matters because the saw is built to keep chain speed and cutting force up when you lean into larger material. DEWALT also states it can cut through a 17 in. white oak log in as fast as 15 seconds using that same battery, which gives you a clear idea of where this saw sits in the cordless chainsaw category.

The 20 in. bar gives this DEWALT chainsaw the reach needed for larger diameter cuts and more efficient bucking. That longer bar makes it a better fit for firewood processing, clearing downed trees, and property maintenance where smaller saws start to feel undergunned. Because it is cordless, you get instant start-up, no pull cord, no fuel mixing, and no idling while you reposition between cuts. For crews and property owners who cut in bursts throughout the day, that convenience is not a small thing. It saves time and makes the saw easier to live with.

From a design standpoint, DEWALT built this model around jobsite practicality. The brushless motor is there for efficiency and durability, and the auto-oiling system continuously lubricates the bar and chain during use. That helps reduce maintenance interruptions and supports consistent cutting performance over long sessions. Tooled chain tensioning is paired with an onboard wrench, so you can tighten the chain as needed without digging through a truck or toolbox. Bar retention matters on a saw in this class, and DEWALT calls that out directly.

Safety and control also get real attention. The chain brake is built in, and the low kickback bar and chain are engineered to help reduce aggressive reaction during cutting. That does not replace good technique, but it does mean this 20 inch chainsaw is set up for the kind of real-world outdoor cutting where buried bark, knots, and awkward branch positions can quickly test a saw. For storm cleanup and property work, those details matter just as much as raw power.

As a kit, the DEWALT DCCS677Z1 60V MAX 20 in. Brushless Cordless Chainsaw Kit comes ready to work with a DCB615 DEWALT FLEXVOLT battery, DCB115 charger, bar sheath, rugged carrying case, sharpening file, and tensioning tool. That is important because this is not a bare tool. You are getting the battery platform needed to hit the published performance numbers, plus the core accessories to store, maintain, and transport the saw properly.

This saw makes the most sense for landscapers, large-property owners, farmers, general contractors handling site cleanup, and serious homeowners who need more than a compact pruning saw. It is also a strong fit for DEWALT FLEXVOLT users who want a cordless chainsaw that can handle thicker wood and routine heavy cutting. If your work regularly involves storm damage, firewood processing, or medium to large tree cleanup, this brushless cordless chainsaw is built for that kind of load.
