Due to its robust thickness of core and a distinctive hardness this drill bit has a long tool life. Especially when drilling with diameters below 6 mm the anti-torsion capability is very high while the danger of fracture is low. It is very suitable for working with alloyed and unalloyed steel, non ferrous metals, cast iron and hard plastics.
