High quality bits for recessed Torx screws. The Impaktor technology offers an above-average service life even under extreme circumstances. Enhanced friction resistance, thanks to the rough diamond-particle coating on the bit tip, prevents any slipping out of the screw head. Particularly suitable for use with customary impact drivers. 1/4" hexagon, suitable for holders as per DIN ISO 1173-F 6.3. Wera Impaktor holder for the absorption of extreme impulse peaks. Special torsion effect thanks to the double-torsion spring. The Impaktor holder additionally holds long and heavy screws absolutely securely. This enables a rapid and dependable positioning of the screw. Ideal also for overhead work. Should, situation-related, the magnet not be desired e.g. when working with metal, it can be removed from the screwdriving zone and thereby be neutralised. Used mostly for manual power tool applications. Output: suitable for bits with 1/4" hexagon head drive as per DIN ISO 1173-C 6.3. Drive: 1/4" hexa
