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 tapered torsion zone of the bit effectively handles torque peaks, as it absorbs forces and vibrations while driving screws. This makes it suitable for a variety of tasks. It features a 1/4-inch external hex shank for general screwdriving 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 mm: 25.
