This extra hard screwdriver bit is a great choice for general tasks. S2-modified steel and an optimized heat treatment process result in above-average hardness for adequate performance in all types of work. The conical torsion zone of the bit effectively handles torque peaks, as it absorbs forces and vibrations while screwing. This makes it suitable for various tasks. It features a 1/4-inch hex shank for general screwing work with screwdrivers and drill drivers. This robust and compact set comes in a transparent storage box, providing both a good overview and secure storage and transport. Length: 25 mm.
