The impact driver — around 180 Nm from a 960 g machine, delivering torque in rotational blows rather than steady pressure. That is why it drives a long screw a drill would stall on, and why it doesn't try to twist out of your hand when the screw bites. It starts without impact so the screw finds its thread, then brings the hammer in as resistance rises.
