Bosch Square Extra Hard Robertson Screwdriver Bit

The Bosch Square Extra Hard Robertson Screwdriver Bit is an excellent choice for universal screw-driving tasks, delivering reliable performance across a wide range of applications. Manufactured from S2 Modified Steel with an optimised heat treatment process, these bits achieve an extra-hard quality that stands up to demanding, everyday use.

The tapered torsion zone is a key design feature, absorbing force and vibrations during screw-driving to cope effortlessly with torque peaks. The 1/4-inch external hex shank ensures a strong, secure connection with maximum torque transmission in both three-jaw chucks and 1/4" internal hex tool holders, making these bits compatible with most screwdrivers and drill drivers.

Available in R1, R2, and R3 Square (Robertson) tip sizes, in 25mm and 50mm lengths, and in packs of 3 or 25 to suit both occasional and high-volume use.
