Bosch Professional Robustline 12+1 Piece Extra-Hard Set

This Extra Hard Screwdriver Bit is a good choice for universal use. All tasks are achievable thanks to the bit´s S2 Modified Steel and an optimised heat treatment process resulting in extra-hard quality, enabling adequate performance in all tasks. The bit´s tapered torsion zone copes easily with torque peaks as it absorbs force and vibrations when screw-driving and thus fulfilling all tasks. This robust and compact set features a transparent storage box providing a good overview of its contents as well as safe storage and transport. It has a 1/4-inch external hex shank and is intended for universal screw-driving with screwdrivers and drill drivers.
