Ingersoll Rand Screwdriver: 1/4 in, Industrial Duty, 15 in-lb to 60 in-lb, 1,700 RPM Free Speed

Inline air-powered screwdrivers align the bit-holding chuck with the tool body to allow fastening in recesses and tight spaces. They also keep the user's forearm in line with the bit to minimize fatigue and allow maximum pressure and control when driving screws into vertical and horizontal surfaces at waist level. They have a lever switch that is pressed with multiple fingers (rather than with a single finger like a trigger throttle) to reduce hand fatigue during extended use.
