Bosch Professional Extra Hard Screwdriver Bit and Nutsetter Set, 43-Piece - £15.95 @ Amazon

The 43-piece set with Extra Hard screwdriver bits and nutsetters is a good choice for general tasks. Screwdriver bits made of S2-modified steel, manufactured in an optimised heat treatment process, offer above-average hardness for high performance with all kinds of tasks. The conical torsion zone of the bits handles torque peaks well, as it absorbs forces and vibrations during use. In addition, the bits are colour-coded for a quick overview and identification of the correct bit type. It has a 1/4 inch external hex shank for general tasks involving screwdrivers and drill drivers.
