This cordless screwdriver features a unique dual chuck design that allows you to instantly switch between two different drills or bits without removing or replacing them. The Switchdriver features automatic torque control that prevents thread stripping and surface damage. Another great feature is compatibility with the Power Share line of batteries from Worx. The screwdriver has two operating speeds and adjustable rotational speed, so you can work with various materials and tasks as efficiently as possible. And the built-in LED backlight ensures comfortable operation even in dark and dusty conditions. Despite its power, the Switchdriver weighs only 2.75 pounds, making it compact and convenient for extended work, as well as working at heights and in hard-to-reach places.
