Wera 851/1 BDC SB SiS 05073334001 Philips bit PH 3 Tool steel DLC coated, alloyed D 6.3 1 pc(s)

BDC = BiTorsion Diamonad coated. Bit with a softer torsion zone, whereby the hardness of the shaft by about 20% compared to the tip is reduced. This will result in the twisting of the bit tips in the event of load peaks largely avoided, which further increases the service life of the bits. With diamond coating to reduce the risk of skidding. The tiny diamond particles bite when screws formally in the screw without risk of injury.
