The Festool combi drill has two modes of operation: drilling and screw driving. A battery is typically used to fuel it. This allows you to choose between low and high torque, which decides how much force the drill uses to push the screw.
It has a brushless EC-TEC motor for maximum output and service life, as well as individual control, LED lighting. It also has a battery status monitor and can be used for easy fastening, drilling, and impact drilling.
