Wera Bit-Safe 61 BiTorsion Screwdriver Bit Set
The effectiveness of the BiTorsion system comes from a combination of two shock absorbing spring elements, both bits as well as holders have a cushioning torsion zone that diverts the kinetic energy away from the drive tip during peak loads.
BDC bits are absolutely premium products, they have a softer BiTorsion zone which reduces the hardness of the shaft by 20% in comparison to the drive tip. This means that peakloads that cause bit breakage and premature wear are absorbed in this zone. The diamond coating lowers the danger of slipping as the minute diamond particles literally "bite" themselves into the screw head.
