The Robust bit-check by Wera. bit-checks provide a quick overview of the tools available. Bits not needed are simply reinserted into the set and do not get lost. Simple transportation e.g. in the shirt pocket. 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. Impakt holder for the absorption of extreme impulse peaks. Special torsion effect due to the double-torsion spring. Comes with a ring magnet that holds even long and heavy screws extremely securely, making it ideal for overhead work. The magnet can be pushed back and thereby neutralised. Particularly suitable for use with customary impact drivers.
