With the BOSCH Cordless Screwdrivers
and Cordless Impact Drill/Drivers, you can not only insert but also remove screws. All you have to do is set the direction of rotation switch accordingly: right rotation for insertion and left rotation for removal. However, so that you can perform screwdriving tasks, you have to insert the suitable screwdriver bits in the drill chuck. There are four suitable bit shapes for different screw heads: slotted, hexagon socket, cross-head and Torx.

If you want to drive several screws in succession into, for example, wood, you can set the turning power or torque by using the torque setting ring. When the machine reaches the set value, it automatically stops driving the screw. In this way, all screws are tightened with the same force. None are over tightened or damaged.  

The main switch controls the rotational speed. It works like the accelerator in a car: the more you press, the faster it moves. That means the more firmly you press the main switch on your Bosch Cordless Screwdriver or impact drill/driver, the faster the machine drives screws or drills.

BOSCH Cordless Screwdrivers and Cordless Impact Driver/Drills have 2-speed gearing. This works in the same way as the gearbox of a car: low speed with high torque in 1st gear, high speed with lower torque in 2nd gear. In switching back to first gear, you select higher turning power. You need this, for example, to insert screws with larger diameters.
