HSS step drill HICOAT
HSS step drills for drilling and deburring thin sheets, pipes and profiles made from various materials. To ensure reliable torque transmission, all step drills have a three-surface shaft. HSS step drills with premium HICOAT coating HC-FEP are wear resistant and versatile as they can be used to process steel, stainless steel (INOX), non-ferrous metals, thermoplastics and duroplastics. Step drills with HICOAT coating HC-FEP provide good high-temperature hardness and resistance to oxidation. They can therefore also be used on hard materials without the addition of coolants.
