Cordless Drill-Drivers

The most versatile drill, it is both a power drill and screwdriver. It is battery-operated, which makes it highly portable and easy to use. The battery detaches for recharging. The differences between types of drill-drivers are usually indicated by their level of power. The higher the battery's voltage, the more powerful the drill — most are in the range of 9.6 volts to 24 volts. A trigger allows control of the drill's speed. A keyless chuck makes it easy to change out bits. Some drill-drivers also have a hammer action.
