Bits for Pozidriv* 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; 1/4" hexagon, suitable for holders as per DIN ISO 1173-F 6.3. * Pozidriv = registered trademark of European Industrial Service Ltd.
