This Bosch Square Extra Hard Robertson Screwdriver Bit is supplied in an R1 Square tip size, 50mm length, in a pack of 3. The longer 50mm length provides greater reach for recessed fixings, deep countersinks, or applications where a standard 25mm bit simply cannot gain adequate access. The R1 tip is suited to smaller Robertson-head screws. Manufactured from S2 Modified Steel with an optimised heat treatment process, this bit delivers extra-hard quality for consistent performance across all screw-driving tasks. The tapered torsion zone absorbs force and vibrations, coping easily with torque peaks during use. The 1/4" external hex shank ensures a strong, secure fit in three-jaw chucks and 1/4" internal hex tool holders.
