The kwb Titanium bits are particularly suitable for serial screw connections. Made of titanium-nitrised TQ 60 steel. This surface finish where the titanium and the TQ 60 steel coalesce increases the strength of the steel and ensures over-average tool life with highest continuous load. The extremely hard titanium surface combined with the torsion zone and the Mega Grip Ribs increases the bit´s tool life by approx. 600 % . With colour-coded rings to distinguish the shape of the head. 1/4″ C 6.3 shank.
