From 45 micro bits, 16 sockets, an ESD handle, a bit extension, a bit ratchet, and an adapter, the comprehensive 66piece precision screwdriver set has thought of everything. Filigree screwdriving work, such as electronics repair, model making, spectacle and watch repair, or smartphone repair, is done in no time thanks to the mini screwdriver set. By and for professionals: the electrostatically dissipative ESD handle of the screwdriver protects against discharge and offers the greatest safety for electrical devices. Bits made of chrome steel promise long use. Thanks to the included bit adapter, you can also use regular bits (1/4" hexagon) in addition to the filigree bits (4mm). This makes the ESD Micro Set a perfect allrounder for your workshop. The storage of the bit set is practical and functional. The labeling of the drive units in the lid and in the box creates order, and every part has its own place.
