The freewheel function allows for a particularly fast return movement without the hassle of setting down when tightening screws. It is especially suitable for Wera torque screwdrivers with a pistol grip, enabling more ergonomic and quicker work. The Rapidaptor technology allows for bit insertion without the need to engage the sleeve. Removing the bit is done by simply pushing it forward, which enables a lightning-fast bit change, even with just one hand.
