The bits in the kwb Impact bit box are ideal for commercially available impact screwdrivers. Thanks to a special torsion zone and modified steel, the bits are absolutely impact-proof and extremely durable, and can easily withstand continuous stress even under extreme conditions. The folding carry case is fitted with snap-in inserts. What’s more, the case contains labels that indicate where the case’s components are stored. This fast find feature and the quick-change bit holder enable swift and effective bit changes. To name but a few examples, the box contains screwdriver bits measuring 25 mm and 50 mm long, socket wrenches and a quick-change bit holder.
