Wiha puts an end to this complexity of considering the appliance used, the fastening type and the large selection of different bits. Thanks to Wiha's revolutionary bit concept, only the screw shape is the deciding factor when selecting the right bit.For example, the Y-bit is ideal for fastening Y-shaped screws with an angle not equal to 90° between the thread and screw head. Thanks to its patented torsion zone, the bit is also suitable for power tools and impact screwdrivers and guarantees a 120x greater lifespan compared to Wiha standard bits. The coloured bits are also quick and easy to find, even in the dark by using an UV light, thanks to its fluorescent coating. This reduces the number of bits which are lost and saves on the expense of acquiring new ones.
