Impact driver driving screws through metal - GIF

It's called a drill point. What poppycock. You could do this with a screwdriver if you were patient.

I dunno. I think this video is more showing how impressive impacts are at driving screws. Impacts are very impressive with respect to driving fasteners with PITA heads like Philips. The intermittent pulses of torque allow the driver to reseat preventing cam out. Those Philips heads would have cammed out and rounded off within a few turns if I were using a hand screwdriver. I would have a pair of vise grips on that screw after about a minute.
