This item is currently not available.


High-quality Impaktor bits for hexagonal socket 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. Hex-Plus ensures a greater contact surface in the head of the screw. The notching effect is therefore reduced to a minimum and damage to the screw head more or less eliminated.

- Particularly suitable for use with customary impact drivers
