This is the FlexVolt saw to buy instead of the 16". The DCCS672 moved to a .050-gauge 3/8" low-profile chain — the commodity size every shop stocks, rather than the narrow-kerf .043 DeWalt uses on the DCCS670 — and DeWalt's own claim is 2.85 peak horsepower, 26% more peak power and up to 2.5x the torque of a 40.9cc gas saw, with a 17" white oak log quoted at 24 seconds. Metal bucking spikes, a chain brake, and an onboard wrench for tensioning instead of a plastic dial. At 11.1 lb bare it is light for an 18" bar, which is the single best thing about it. The caveats are the platform's, not this saw's: a 3.0Ah FlexVolt pack is a modest battery behind an 18" bar, so expect short sessions, and DeWalt's 3-year warranty is the shortest here apart from Makita's, which matches it.

Best for: Property owners on FlexVolt who want a real 18" bucking saw and refuse to run narrow-kerf chain.

Manufacturer figures except the engine class and single-pass cut, which are derived here. What each spec means

3/8" LP, .050 gauge
11.1 lb bare
17" oak in 24 seconds

Where it is strong

Full .050 gauge on 3/8" low-profile — the most widely stocked loop size in America, not a proprietary narrow kerf
11.1 lb bare for an 18" saw, lighter than most battery saws two inches shorter
DeWalt claims 26% more peak power and up to 2.5x the torque of a 40.9cc gas saw
Metal bucking spikes and an onboard wrench for tensioning rather than a plastic dial
Street price around $395-$439 for the kit, well under the 18" Makita and 20" Milwaukee

Where it falls short

The included DCB609 is only 3.0Ah at 60V — a small tank behind an 18" bar
3-year limited warranty, half of EGO's and Milwaukee's tool coverage
No case in the X1 kit, just a bar sheath and tensioning tool
The FlexVolt oiler is the range's known weak point — see the 16-inch DCCS670 entry on this site — so check bar oil delivery on the first tank
Nothing on board tells you charge state — you read the pack, not the saw
