This Bosch Square Extra Hard Robertson Screwdriver Bit is supplied in an R1 Square tip size, 25mm length, in a pack of 3. The R1 tip is designed for smaller Robertson-head screws, and the compact 25mm length makes it ideal for confined spaces and precision work where a shorter bit gives better control. Constructed from S2 Modified Steel with an optimised heat treatment process, this bit delivers extra-hard quality for reliable 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.
