Manufactured with an extremely hard titanium nitrite coating (TiN), the HSS step drills master every challenge. The precision-ground cone drills reliably drill into the metal to be processed. Thanks to the durable TiN coating, the countersink drills are heat-resistant, wear-resistant and ensure a long service life. The high-quality drill set consists of three HSS TiN step drills in sizes 4-12 / 4-20 / 4-32 mm. The coated peeling drills have a service life that is up to 400% longer than conventional HSS drills and are suitable for alloyed and non-alloyed steels such as cast iron, non-ferrous metals and plastics. The metal drills are delivered in a robust aluminum box for safe transport. The drill set is ideal for professional use in industry, crafts, workshops and DIY.
