Manufactured with an extremely hard titanium aluminum nitrite (TiAlN) coating, the HSS step drills master every challenge. The precision-ground cone drills reliably drill into the metal to be processed. Thanks to the durable TiAlN coating, the countersink drills are very heat-resistant, wear-resistant and ensure a long service life and a long service life. The coated step drills have a service life that is up to 10 times longer than conventional HSS drills and are suitable for alloyed and non-alloyed steels such as cast iron, non-ferrous metals and plastics. Thanks to their titanium-aluminum-nitrite coating, the countersinks have high heat hardness and oxidation resistance. For safe transport, the metal drills are delivered well sorted in a robust plastic storage box. The different sizes of the cones are clearly displayed on the cone drills themselves. The complete set consists of 5 step drills in different sizes. The cone drill set is particularly suitable for professional use in industry, crafts and DIY.
