DeWalt 60V Max FlexVolt 20" Chainsaw Kit

On peak output it's legitimate: up to 3,100W (about 3.49 HP), a 50.2cc-gas-equivalent claim, and testers found it rips through 16-inch-plus hardwood at speeds that embarrass 45cc gas saws. The gap versus gas shows up in sustained work rather than single cuts — see the thermal and battery caveats before planning a full firewood day around it.

Owners report thermal shutdowns and fast battery sag under sustained bucking — the saw protects itself and the pack when worked hard back-to-back. Pacing your cuts helps, but realistically a second FlexVolt pack (at $300+) is near-essential for extended sessions, both for runtime and to let packs cool between rotations.

It's the weakest retail aggregate of any major-brand big battery saw, though from a small pool (19 reviews). The recurring themes are the thermal/battery behavior under sustained load and durability complaints around the oiler and electronics. The counterpoint: professional testers rate its cutting speed highly, so it reads as a fast saw with consistency questions rather than a slow one.

Yes — unlike most battery rivals' tool-free knobs, the DCCS677 uses tooled tensioning, so you're fishing out the scrench for every adjustment. The upside is that the dual bar studs hold the bar more securely than the tool-free systems on competing saws. Chains are no problem: it runs standard 3/8/.050 70-drive-link loops available from any saw shop.

The heaviest in its class by a wide margin — 17.2 lbs with the FlexVolt 4.0Ah pack, versus about 19.4 lbs for EGO's CS2005 with battery but well above 50cc gas powerheads and every 16-inch battery saw. It's a saw you bring to planned cutting, not one you carry around the property all day. The included hard case, rare at any price, at least makes transport civilized.
