Bits for Pozidriv* screws with tiny diamond particles on the bit tip. These ensure a secure fit in the screw, reduce the required contact pressure and reduce the risk of slipping. With torsion zone, into which kinetic energy is dissipated at peak loads. With softer bi-torsion zone to avoid twisting of the bit tip under high loads. This significantly increases product life. 1/4 inch hexagon, suitable for holders according to DIN ISO 1173-F 6.3. * Pozidriv = registered trademark of European Industrial Service Ltd.
