The A510 is the primal ADX drill. This unique Dormer HSS is unrivaled in productivity. The ADX is characterized by its ability to work with high feed rates with a wide range of material and type of machine to be drilled. The approximately 25% higher feed in combination with the +/- 40% higher cutting speed than standard twist drills ensure that the chip formation becomes better and drills much faster. The costs per drilled hole are quickly reduced by using this high productive twist drill. In the meantime, VHM drills are often also chosen for high productivity. When the stability or available power is insufficient for VHM, the ADX is the better choice. This cylindrical drill has a TiN coating for better wear resistance.
