Cordless impact wrenches: pick by torque class.
Passenger-car wheels torque to 110–140 N·m, so the 320 N·m entry already clears them. SUVs and light trucks want 380 N·m. Seized, rusted or heavy-vehicle fasteners are the 800 N·m class’s job — the hammering action, not leverage, breaks the rust bond.
