Wera BiTorsion Diamond Phillips Screwdriver Bits

High quality bits for Phillips screws with tiny diamond particles on the bit tip. This ensures a secure fit of the bit in the screw, reduces the contact pressure required and lowers the risk of slipping. Comes with Torsion zone – where kinetic energy is diverted from peak loads – and softer BiTorsion zone to prevent the bit tip from twisting under peak loads. This greatly extends the product service life; ¼” hexagon, suitable for holders as per DIN ISO 1173-D 6.3. Features and Benefits:
