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 various types of work. The tapered torsion zone of the bit effectively handles torque peaks, as it absorbs forces and vibrations while screwing. This makes it suitable for all kinds of jobs. It features a 1/4-inch external hex shank for general screwing tasks 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.
