The Impact Control screwdriver bit is extremely robust, ideal for heavy work and can withstand even the high torque of impact screwdrivers. The special torsion zone gives the bits extreme durability for longer working hours. S2-modified steel and optimized heat treatment process give maximum durability for best performance, even with extensive assembly and heavy industrial work. The HEX-9 MultiConstruction drill is ideal for use with materials of almost all types in interior fittings. It has diamond-ground cutting edges with high wear resistance and a two-spiral U-shape, which ensures good drilling dust removal and a long service life. In addition, the carbide tip allows easy drilling and good drilling guidance. All bits have a 1/4 inch external hex shank and are suitable for use with drill drivers, screwdrivers and especially impact screwdrivers. The bits are part of the Bosch Pick and Click system, which enables individually assembled accessory sets for absolutely flexible bit sets.
