This Bosch PRO Impact Control Robertson Screwdriver Bit is supplied in an R2 Square drive, 90mm length, as a single bit. The extended 90mm length gives added reach for deeper recesses, awkward angles, and applications where a standard 55mm bit simply won't reach. Up to 50x more robust than the Bosch Extra Hard Bit, this bit is constructed from heat-treated modified steel for exceptional strength and high torque resistance. The extended torsion zone absorbs torque stress at the tip, keeping the bit intact under sustained heavy-duty use. Colour-coded rings and laser size markings allow for instant identification, even when working quickly. The 1/4" impact-rated hex shank ensures full compatibility with impact drivers and drill drivers.
