That 380 Nm of tightening torque is actually pretty generous for a cordless 1/2-inch — most guys in teh shop find it handles lug nuts on trucks without breaking a sweat, though your mileage varies with battery age.

We ship these with the 4.0Ah lithium pack, and charging takes about 2 hours, which is standdard for this class, but you'll get maybe 50-60 lug nuts on a single charge depending on how rusted everything is, and the brushless motor saves you replacing brushes every few months — basically a maintenance win for busy shops.

One thing I usually mention, and it's not on every spec sheet, is the hog ring on the anvil, that quick-release chuck holds sockets way better than pin-type setups, so you're not chasing dropped sockets under cars all day. Also, the brake stop isn't just marketing fluff, it actually stops the output shaft fast when you let off the trigger, which keeps your knuckles intact when you're working in tight engine bays.

The weight is 1.1 kg without the battery, so with battery it's about 1.6 kg or so, feels balanced for one-handed work but it's not a lightweight for overhead stuff, really better suited for wheel changes and suspension bolts.

0 to 2,500 RPM and 3,500 impacts per minute is range, and honestly most buyers go with the mode selector to dial it down for smaller bolts like M8 or M10, since at full tilt it'll snap M8 bolts in half if you're not careful.
