While the main use for portable drills is to drill holes, a drill with a controllable angular velocity (variable RPM) can be used as a screwdriver. The Tulane MakerSpace owns several types of portable drills.
1/2" (maximum hole [= drill bit] size) corded (gets power from wall power outlet) drills produce high torque at lower speeds. They're heavier and typically used to drill large holes in wood or metal. All have a side handle that must be used, so you will have two hands to control the tool and keep the tool from twisting, which can lead to injury.
