Some of the early power drills came with built-in screw-jack type devices to force the tool into the work. Some had a large nut with two or four handles (think of the handles around a ship's wheel, but much smaller), and pushed out a threaded rod with a pointed end to apply pressure. Some of these were used to drill railroad rails in order to install fish plates connecting them to adjacent rails, so they NEEDED some pressure. At least some I've seen in pictures didn't have conventional handles at all, and were not really usable except in a cradle or fixture. With their torque, they'd have been unsafe in hand-held use, even if they weren't so bulky and heavy.
