Drills are more powerful and have a longer battery life, but they are also heavier in tight spaces. Cordless screwdrivers are lighter and have more maneuverability, but their battery life is shorter, and their power output is weaker. With these things in mind, you are sure to find the right tool for your next project.

A power screwdriver can serve as a drill for certain projects, but it is critical to remember that it is not suitable for heavy-duty drilling tasks such as metalworking or concrete work. For those types of jobs, choose an electric drill or even an air drill due to their increased power and torque output.

1. Hold the tool firmly with one hand on the grip and the other hand on the bottom of the battery pack to control the twisting action. 2. Place the point of the screwdriver bit align to the screw head and apply pressure to the tool, start the tool slowly and then increase the speed gradually.

To use an electric drill as a screwdriver, you need to fit it with a screwdriver bit that matches the screw head type. The bit is inserted into the drill's chuck, tightened, and the drill's direction switch is set for tightening or loosening screws.
