The double design with the same or different blades increases the utility value. It features a 1/4-inch outer hex shank 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 provide above-average hardness for adequate performance in various 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 all kinds of tasks.
