What repairs are possible without bits? You can't unscrew or screw anything without bits, unless you have a classic screwdriver (or preferably a dozen, because there can be many fasteners). The set consists of 32 different bits, which are suitable for both screwdrivers and electric screwdrivers. All bits are made of alloy steel, have magnetic properties and a special anti-wear coating, which will help make the bits more durable. The sets include different torxes, hexes, flat and shaped bits. The length of the bits is 25mm and the diameter of the seating face is 6.3mm. They are fixed and stored in a special plastic stand.
