The double design with the same or different blades increases usability. It features a 1/4-inch external hex shaft for general screw work with screwdrivers and drill drivers. This extra hard screwdriver bit is a good 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 during screwing. This allows for the completion of various tasks.
