A power drill is a type of electric-powered, handheld power tool consisting of a handle bar with a trigger (similar to a handgun) that activates the device's motor when pressed.
Despite the name, modern power drills are not exclusively a drill as they are now designed to be modular, with the drill head can be swapped with various types of other heads for different purposes.
Not to be confused with impact wrench, which has similar design but is otherwise a different type of tools.
