59 ft/s of chain speed is the headline, and it is a real number — more than double the WG384's 26 and in the territory 60V saws from Toro and Greenworks occupy. Worx gets there with a brushless motor and two 4.0Ah Power Share Pro packs, which is also why the kit price lands near $250 while the tool-only WG385.9 sells for well under half that. Where it loses is mass: 15.3 lb with both packs fitted makes this the heaviest 16-inch battery saw here, heavier than most 50cc gas saws; Worx lists the bare tool at 12.4 lb, so roughly three pounds of that is battery. Worx does not publish a chain gauge for it, which matters when you go looking for a replacement loop. Treat it as a firewood saw you set down between cuts rather than one you carry up a ladder.

Best for: Firewood and storm cleanup on the ground, for Power Share Pro owners who want 60V-class chain speed without a new platform.

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

59 ft/s chain speed
Brushless, 2x4.0Ah Pro packs
15.3 lb — heaviest 16-inch battery saw

Where it is strong

59 ft/s chain speed is 60V-class and more than double Worx's own WG384
Brushless motor, so it holds speed under load better than Worx's brushed saws
Two 4.0Ah Pro packs make it the largest energy budget of any kit in this group
5-year warranty on the tool
WG385.9 tool-only is far cheaper for owners who already have Pro packs

Where it falls short

15.3 lb listed is the heaviest 16-inch battery saw here — overhead work is out
Worx publishes no chain gauge for this model, which complicates buying loops
Still needs two matched packs to run at all
Kit pricing ranges roughly $240 to $295 across retailers for the same SKU
A 16-inch bar on a battery saw this heavy competes directly with lighter 60V saws
