Even breaks through reinforcements. Highly suitable for concrete and natural stone. Great details such as solid carbide blades and reinforcement chamfers have been developed to ensure absolute high-performance in difficult drilling ground and a very long service life. Impacts and torsion forces are absorbed in the drill head thanks to maximised connecting surfaces between the hard metal and steel. The reinforcement chamfers ensure optimised drilling behaviour and prevent catching when reinforcements are hit. The four spiral backs work evenly, which in turn reduces the spiral wear.
