BiTorsion Bits

Peak forces that occur in power tool applications often result in premature wear of bits or damage to the screw head.This usually occurs during initial power up and the when the screw comes to standstill. Screwdriving could become more productive and safer it these peak load could be minimised. The Wera BiTorsion system prevents premature wear. The service life of the tool is extended and the productivity of power tool applications significantly increased.
